This paper is a discussion of the history and future of Harpoon
Swordfishing in Southern California. It covers how the fishery operates
and how it has been affected by the introduction of new technology
and by other fishing methods. Also included is a discussion of the
unlimited fishing pressure applied by the Mexican near shore Swordfish
fleet. More importantly, the paper compares the current state of
Swordfishing in California and Mexico with the collapse of the Swordfish
industry in Chile. The parallels are too frightening to ignore when
discussing the future of this fishery. They dramatically show how
indiscriminant fishing techniques such as gillnetting and long lining
destroy a priceless fishery resource. The conclusions offer some
disturbing news. The recommendations offer stringent but necessary
management tools for consideration.
HARPOONS
THE ORIGINAL ROD AND REEL!
"Harpoon Swordfishermen today, as in the past, use their eyes
to find the fish. It follows that they see every kind of life that
swims on or just below the surface while they fish. It also follows
that when they see very little life swimming around their boat they
know something is very definitely wrong. The boat is in the wrong
place, or the life is gone!" Larry E. Mebust
INTRODUCTION and SUMMARY
THE CALIFORNIA HARPOON FISHERY for SWORDFISH
The Harpoon Swordfishery in California is a traditional fishery.
It is documented as having been practiced by West Coast Indian fishermen
dating back as far as 3,000 years. Modern commercial Harpoon fishing
in California began around 1900 utilizing sail powered sloops or
schooners. The gear in use today has changed little since then except
for the materials from which it is made. With the advent of new
fishing methods, harpoon swordfishing will probably never again
be the primary way to catch swordfish; but it will always be the
leading indicator, or bellwether, by which to measure the health
of the stock and thus the performance of those who manage that stock.
TROUBLING LANDINGS DATA
Until the deployment of Drift Gillnets in the late 1970's, the
harpoon was the primary gear type in use in California. Since the
deployment of the Driftnet, the landing statistics indicate to us
that a classic "boom/bust" scenario has already occurred
in California's near shore fishery with swordfish landings steadily
decreasing since they peaked in1985.
DRIFT GILLNETS AND LONGLINES ARE TOO EFFECTIVE
Unmanaged or under-managed fishing with both Drift Gillnets and
Longlines has been proven to lead to overfishing and ultimately
to failed fisheries. Our near shore fishery has for the past ten
years, exhibited all classic signs of excessive fishing for swordfish
and other species. These gear types have also been proven to produce
unacceptable levels of by-catch and discarded catch. These gear
problems must now be dealt with objectively; they can no longer
be ignored. I tenaciously support every commercial fisherman's right
to fish for a living and to feed his family. However, I believe
that this right comes with the direct responsibility to fish in
a manner that shows concern for the fish stock as well as the entire
ecosystem.
THE WRITING IS ON THE WALL
The California/Mexico near shore fishery for swordfish parallels
that of Chile in its evolution: Harpoons to Driftnets to Longlines.
Chile began introducing stringent management measures far too late
in the evolution to prevent the collapse of its swordfishery. The
new measures may someday allow the rebuilding of the Chilean fishery,
but for now it is commercially unviable. The recent introduction
of Pelagic Longlines into our off shore fishery (outside the 200
mile Exclusive Economic Zone, EEZ) in California is the final requirement
for us to evolve into a mirror image of Chile.
Hopefully the conservation and management measures evolving from
the current efforts of the Council will preclude that evolution.
MORE EFFECTIVE MANAGEMENT IS REQUIRED
My specific concerns are itemized and quantified in this document,
as are recommendations for change. New national and international
conservation and management measures are desperately needed if swordfishing,
and especially Harpoon swordfishing is to remain a commercially
viable fishery in California.
THE CALIFORNIA HARPOON FISHERY for SWORDFISH
Today's harpoon swordfishery in California was clearly and in the
main, accurately described from both a technical and historical
stand point by ATILIO L. COAN JR., MARIJA VOJKOVICH, AND DOUG PRESCOTT
in their paper, The California Harpoon Fishery for Swordfish, Xiphias
gladius. The historical description in the introduction and many
of the statistics utilized in the writing of our paper were obtained
from this work. Credits for the usage of their information in are
given and herein, their work is referred to as Coan et al, 1994.
I disagree with some of Coan's conclusions regarding the California
harpoon fishery and discuss these later.
Harpoon fishing pressure is limited by nature
Harpoon swordfishing in California is limited annually by two major
factors. First, swordfish are only found in fishable numbers in
the calmer waters of the Bight between June and November. This is
due to the annual northwesterly push of the North Equatorial Counter
Current. Secondly, the winter and spring weather in the area tends
to be too rough to operate in with a harpoon pulpit extended. These
two conditions levy a natural, seasonal closure on the harpoon fishery.
The other gear types fish in all but the worst of weather conditions.
Boat / Airplane "team fishing"
The boat/airplane team harpoon fishery, as it is today, began to
evolve in the early 1970's when airplanes were introduced. Initially,
infighting between the purists and those intent on modernization
caused the airplanes to be a very limited factor in the fishery
for over ten years. The planes were banned by the DFG for one year
during 1976. In 1984, airplanes were finally allowed full time in
the fishery. This only occurred after many of the boats had been
converted to fish drift gillnets. The modern, I believe technically
correct, boat/plane team-fishing model for swordfishing never had
a real opportunity to show what it could accomplish in the market
place before the near shore swordfish stocks began to show a serious
decline in numbers.
The harpoon swordfishery produces zero by-catch
By-catch in any fishery describes those non-targeted animals that
are incidentally or accidentally taken by the fishing gear while
fishing for the target species. Harpoon swordfishing produces absolutely
zero by-catch! A harpooner intentionally takes every single fish
landed by his boat.
Average weight of landed harpooned swordfish
Coan et al, 1994, describes the average landing weight of harpooned
swordfish during the period 1981 - 1993 as being 85 kg (187.4 lbs.)
and explains that they did not have total numbers of fish, only
total weight with which to calculate the number. Coan's average
is low when compared to average weight per fish data reported by
harpoon boats from landing receipts. My calculations of annual average
dressed weight per fish taken by harpoon over the past ten years
averages approximately 90.7 kg (200lbs.). This varies from about
195lbs to well over 200lbs on a boat-to-boat basis over the same
ten-year period. The primary reason for this higher average weight
(than other gear types) is selectivity. Harpooners seldom take juvenile
swordfish.
Intentional take of secondary species
Some harpoon boats take Mako sharks as a secondary species due
to its readily marketable meat. Makos in the one hundred to one
hundred fifty pound range tend to be the shark most likely to be
taken due to the steak quality of that size fish. In recent years,
however, sharks of this size are seldom seen in the Bight. My boat
quit taking shark's altogether due to a combination of low price
and the modern knowledge about the animals' limited ability to reproduce.
Erroneous harpooned shark landings disputed.
The data indicate that in the late 1960's sharks were not routinely
targeted or landed by Harpooners (Coan et al, 1994); this is the
norm for the fishery. Table 1 in Coan's work shows that between
1969 and 1974 harpooners landed only 53 Mako sharks, all in 1970.
Beginning in 1977, the data show a massive increase in shark landings
by harpooners including hundreds of metric tons of Thresher, Mako,
Blue and other sharks.
These dramatic numbers are undoubtedly accurate, however harpooners
did not take these sharks! The beginning of these landings coincides
precisely with the beginning of the drift gillnet fishery. The driftnet
fishery was originally licensed as an "Experimental near shore
Shark fishery" targeting Threshers and Makos with swordfish
as by-catch. By rule, swordfish landings could not exceed shark
landings. Coan theorizes that those boats with both permits (harpoon
and drift gillnet) simply assigned enough of their sharks to their
harpoon catch in order to make their high percentage of swordfish
landings appear legal.
At this writing, I understand that due to Coan's work, the Department
of Fish and Game and NMFS both understand why these old figures
are erroneous. They are, however, part of the record and I mention
them for the benefit of others who may read this paper. This "unexpectedly
high by-catch problem" must become a lesson learned for those
who evaluate future requests for "experimental fisheries."
Harpooners service a demanding niche market
Harpooners have developed a specialty customer base in the high
quality seafood restaurant market. The Department of Fish and Game
licenses many of these first quality restaurants as fish receivers.
A direct sale to this market produces better income for the fisherman.
It rewards his efforts to deliver truly fresh fish to the end user,
and assures the customer of a consistently high grade of product.
Only when the fisherman-direct market is satisfied do the harpooners
begin to deliver to wholesale buyers. Even wholesale buyers will
generally pay more per pound for the harpoon product than for swordfish
caught by other gear types. As a general rule, when a harpooner
calls a wholesale buyer to sell fish, those fish are already sold
to restaurants by the time of delivery to the buyer. Harpooned swordfish
are often referred to by the wholesalers as "cherries"
thus acknowledging the high quality of the product.
Our markets demand top product quality
Harpooners pride themselves on the high quality of their product.
This notable quality is due the handling of the fish after it is
harpooned. Once aboard, the fish are bled immediately. This single
action improves the color and quality of the meat markedly. (The
meat from any fish that dies with its blood in the meat will be
darker and stronger tasting than that from a fish which has been
bled. Side by side, a steak from a bled fish appears pink or white,
while a steak from a fish that died without being bled will appear
brown in color.)
After bleeding, the fish are immediately finned, gutted, trimmed
and the body cavity thoroughly scrubbed before they are placed in
the refrigerated fish hold and iced down. The fish are re-iced after
about 12 hours to replace the ice lost in the cooling process.
Most harpooners try to unload their fish within 1 to 3 days after
catching them. Although refrigerated swordfish does hold very well,
the harpoon customer base generally wants the fish as soon as they
can have them.
Harpooning is a bellwether fishery
Harpooning on the California coast is a fishery in decline. This
is because it is becoming more difficult to make a profit with every
passing year. The foregoing statement poses the question: "why
is it harder to be profitable"?
Coan's work states "competition from the more efficient drift
gillnet fishery since 1980 has resulted in decreases in harpoon
catches." I strongly disagree with this statement in two important
ways. First, the term efficient cannot be applied to the use of
gillnets to catch swordfish. They are certainly effective at catching
sea animals, but efficiency requires getting the job done without
creating damage. Secondly, harpooners do not and cannot compete
with the drift net fishermen in numbers of fish caught! Harpooners
pride themselves on catching and delivering only one thing - high
quality fresh swordfish! They are, I believe, willing to live with
a Catch Per Unit of Effort (CPUE) that I below that of the other
available gear types in order to be selective. However, harpooners,
myself included, must remain profitable to continue fishing.
The steadily decreasing catch levels and resulting limits on profitability
result directly from a steadily declining stock of fish! It's simple:
less fish available to catch = less fish caught = less profitability!
There is only one reason for this: the swordfish stocks have diminished
due to excess fishing in the near shore waters of both Mexico and
the Bight of California, our primary fishing grounds.
Harpooners only fish in the top layer of water where the fish fin
or bask. It stands to reason that we only see a percentage of the
fish in a given area on a given day. If the stock of fish in that
area is healthy, we see plenty of fining fish. If the stock is small,
we see very few. Unfortunately, even with the use of airplanes,
"very few fish" is becoming the norm.
The near shore harpoon fishery for swordfish is in trouble because
the near shore swordfish stocks are in trouble! We are the same
bellwether that first forecast the demise of both the North Atlantic
and Chilean swordfisheries - the Harpooners.
The U.S. drift gillnet boats are by no means completely responsible
for this decline in the near shore stocks. The U.S. flagged driftnet
boats are managed to an extent by the CDFG by means of time/area
closures. The virtually unmanaged Mexican near shore drift gillnet/longline
fleet has landed (and imported to the U.S.) all the swordfish it
was capable of catching over the past 15 years. These Mexican landings
must be included in any future studies of the health of near shore
swordfish stock. The Mexican fleet must also be included by treaty
or other means in any viable fisheries management plan affecting
California based swordfishermen.
TROUBLING LANDINGS DATA
A NOTE ON DATA
The graphs in this section were created using thirty-nine years
of landings data obtained from the NMFS database. It should be noted
that an average of one metric ton per year of landings shown as
"Harpoon" can be attributed to unknown gear types. These
are the occasional landings made by purse seine boats and other
gear types not normally associated with swordfish.
FIGURE 1
Actual harpoon landings - Figure 1
Figure 1 shows the record of landings by the California harpoon
fleet for this thirty-nine year (39) period. At first glance the
chart would indicate that swordfish just come and go haphazardly
in the waters of the California Bight. There is no information to
explain the low catch recorded for 1962 except to say, "the
fish just didn't show up." An over reaction to mercury levels
in some international fish stocks caused the 1971 dip; many boats
just didn't fish that year. The 1976 dip was also primarily man-made
due to airplanes being totally disallowed by the DFG for that year.
1978 - THE UNEXPLAINABLE YEAR
During this period came the fishing season that no one could have
believed and many still don't -1978. The harpoon boats could go
anywhere in the Bight of California and find between ten and twenty
fining swordfish in any given day. They could return to the same
little piece of water every day with the same results - more fish.
From San Diego to Santa Cruz Island the ocean was alive with swordfish
for the taking. Airplanes were the last thing on anyone's mind during
this season. There is no harpooner alive today who, having experienced
that season, won't tell you that it was a one in a million year.
The current belief about 1978 is that it gave a one-season look
at the large stock of swordfish that once populated the near shore
waters of southern California and Mexico.
I have created a five-year moving average of harpoon landings to
produce a long-term trend analysis of the data. In the interest
of smoothing out the radical three year peak in the harpoon graph
which was caused by the astounding landings in 1978, the actual
data point for 1978 (1171 mt) was replaced with the arbitrary figure
of five hundred metric tons (500 mt). This figure serves to acknowledge
a great year without creating a misleading three-year peak for the
harpoon fleet. The blue (diamond) aircraft data points are arbitrary
and only serve to show limits and closures placed on aircraft use.
Airplanes - The key to the harpooners success
Even with limited ability to use spotter planes, the landings for
the harpoon fishery were trending upwards. Experience dictates a
harpoon boat with a spotter plane will catch approximately three
times the swordfish than a boat with no airplane. This is due to
the plane's ability to see sub-surface fish and those fining fish
that are beyond binocular range. Airplanes were finally allowed
into the fishery full time in 1984, one year before the drift gillnet
fishery peaked and began a precipitous decline in landings.
Drift Gillnets - the new swordfishing gear
- Figure 3
During the mid-1970's a few harpoon swordfishermen began to experiment
with using drift gillnets to catch sharks. To say the least, this
gear proved to be highly effective at catching anything that swam
into it, especially sharks and swordfish. They were issued experimental
gear permits as a shark fishery. This group of boats generally had
drift net gear on the aft deck and a harpoon pulpit on the bow -
the best of both worlds. The boats began fishing the nets in 1978,
steadily increasing their annual catch of swordfish by an average
of nearly five hundred metric tons (500 mt) per year by 1980. This
success peaked in 1985 with landings of over twenty four hundred
metric tons (2,400 mt) of swordfish alone.
This dramatic success was followed by an almost equally dramatic
decline in landings beginning in 1986 when landings fell to just
under seventeen hundred metric tons (>1,700 mt) beginning a precipitous
slide. By 1991 annual drift net landings had fallen to less than
eight hundred fifty two metric tons (>852 mt) for the fleet!
This rise followed by a continuing decline, points toward a classic
case of exceeding the maximum sustainable yield for a species in
a given geographic area.
FIGURE 3
The graph (Figure 3) clearly shows a precipitous drop in swordfish
landings beginning in 1986. It also clearly shows no signs of recovery
for the near shore stock in the Bight. I am quite certain, although
location of catch data is not available, the sub-peak shown for
drift gillnets occurring in 1992 and '93 includes many metric tons
of fish that were actually caught outside and above the Bight. I
can say this because the drift gillnet fleet fished along side of
us until late October for these two seasons and then moved to northern
waters. 1993 was the last profitable year for many harpoon boats.
Where did they fish?
Most of this early catch came from the Bight of California. This
was where these new gill-netters had grown up fishing as harpooners
so this is where they fished with their driftnets. When, in just
a few years, the Bight quit producing swordfish in the quantities
they had become accustomed to the larger drift net vessels moved
outside the Bight and North, working between the Cortez Bank and
central California. By doing so they were able to continue fishing
on the near shore stocks of fish that move north from Mexican waters
each year. (See also the discussion of the California Bight as a
fishery later in this document.)
Where do they fish now?
A group of smaller near-shore San Diego and Los Angeles based drift
net boats still fish along the border and in the waters of the Bight.
However, because they have had such limited success fishing within
the Bight over the past ten years, most of the larger Southern California
based drift net boats travel directly to the outer edges of the
Bight or to the escarpment between Pt. Conception and Morro Bay
when the season opens in August. These boats now follow the fish
into northern California and sometimes Oregon state waters before
their near shore season ends in January, or when they are forced
to move south due to weather.
The development of the Mexican fleet.
In 1985 two of these California drift gillnet fishermen theorized
that they could catch more fish in Mexican waters if they could
only fish there. With swordfish available year round, they would
only have to limit their fishing time during hurricane season. These
Americans approached the Mexican government with a proposal to fish
in Mexican waters. In return for their permits they would teach
the Mexicans how to fish for swordfish using drift nets. The program
was a rousing success. The Mexican fleet of swordfish boats grew
dramatically and is still fishing today. Most of the fish caught
by this fleet is imported to the United States after being landed
in Mexico. Although only one American captain remains fishing in
Mexico today, the fleet is now modernizing itself. The Mexican fleet,
as of this writing, has converted all of its approximately 50 near
shore driftnet boats to longline gear because it is more effective
in terms of Catch Per Unit of Effort (CPUE). To my knowledge, Mexico
still doesn't impose closures or limits of any kind on its swordfish
fleet.
Longline fishing - The newest technology
In 1991, three Gulf of Mexico based longliners arrived in southern
California and began test fishing for swordfish and tuna. This fishing
was reportedly to be carried out outside of the 200-mile U.S. Exclusive
Economic Zone, EEZ. Without observers aboard, it is impossible to
tell exactly where the fishing was, or is being, done.
Longline landings
According to VOJKOVICH et al 1994, during 1991 and 1992 respectively,
these three boats landed 27.5 and 28.8 metric tons of swordfish.
In August of 1993, numerous longline vessels from the Gulf of Mexico
began arriving in southern California. Landings for 1993 jumped
to 101.3 metric tons. In 1994, with thirty-one boats in California,
landings were reported to be 496.7 metric tons. Also stated in the
Vojkovich paper is the fact that by sampling the catch, the average
weight of the fish being caught was 139 lbs. The actual sample breakdowns
were 13% under 55lbs. with the smallest of these weighing 13 lbs.,
35% weighed between 55 and 110lbs., 35% weighed between 110 and
220lbs., with the remaining 17% weighing over 220 lbs. This is the
same experience the Chilean longline fleet had just a few years
before the fishery collapsed.

Updated longline landings information is plotted in Figure 4
The information contained in Figure 4 is the latest available NMFS
data and indicates a much higher success rate during the test fishing
and early fleet fishing years. The latest data available shows the
1991 landings to be 39.4 metric tons followed by 95.5, 165.5 and
739.7 for 1992, '93 and '94 respectively. I have plotted the available
NMFS landing data for this fishery through 1998.
In addition to the Gulf of Mexico-based fleet fishing off of California,
a large group of Hawaiian based longliners set up their operations
in Los Angeles harbor in 1999. These boats are now fishing the eastern
Pacific stocks that annually feed the California in-shore fishery.
I believe the final boom of the classic boom-bust cycle that occurred
in Chile is now or soon will be, in full swing in California and
Mexico.
DRIFT GILLNETS AND LONGLINES - TOO EFFECTIVE AND
TOO INEFFICIENT
EFFECTIVENESS
I created a five-year moving average (not shown) of landings for
each of the three fisheries to produce a long-term trend analysis
of the data. Again in the interest of smoothing out the three-year
peak in the harpoon graph caused by 1978, the actual data point
for 1978 (1171 mt) was replaced with the arbitrary figure of five
hundred metric tons (500 mt).
Harpoon landings
The graph (not shown) clearly shows that until the deployment of
drift gillnets, harpoon landings were slowly rising. With what is
now known (after 1984) about the effectiveness of airplanes in the
fishery, a fleet of fifty airplane/boat harpoon teams would have
easily stabilized the harpoon landings well above 700 metric tons
of swordfish per year with the previously healthy fish stocks.
Drift gillnet Landings
My graph (not shown) clearly shows a sharp decline in catch after
just 10 years of targeted fishing with drift gillnets in the near
shore waters of the California Bight. The actual peak of this fishery
occurred in 1985, the year that Mexico first deployed drift gillnets.
The chart shows a continuing, long-term trend toward further decline
in the fishery. I feel this continuous decline in landings must
be addressed by the Council as evidence of exceeding the Maximum
Sustainable Yield in any plan development process.
Longline landings
It is apparent from the sharp rise of the graph that the longline
fleet has targeted the pelagic population of swordfish that exists
off our coast and which feeds the near shore and Bight fishery.
The graph is almost as vertical as that of the early gillnet efforts.
Based upon harpooners visual observations of these longliners unloading,
it is logical to forecast the graph will rise much more steeply
after the 1999 counts are tallied. It can also be forecasted with
certainty that its eventual fall will come, and that its fall will
be every bit as precipitous as was its rise. While these predictions
are dire they are easy to substantiate. One need only review the
landing data, which shows that 50% of the fish being landed are
sub-adult pups, not swordfish!
EFFICIENCY
Drift gillnets and longlines are not efficient!
Targeting brother Commercial fishermen for additional grief based
upon their levels of by-catch and discarded catch is not the intent
in the discussion that follows. The intent is simply to reiterate
concerns about the use of the term efficient to describe both drift
gillnets and longlines as gear types. Coan et al, 1994 states that
drift gillnets are efficient. Lindgram Pittman, the producers of
a major amount of the pelagic longline gear in use today also brag
about the efficiency of their gear. I absolutely disagree with the
use of this term to describe these gears.
Both gear types are extremely effective at catching a wide array
of sea life. Anything that swims in the ocean at the depths these
gears are fished is liable to be caught by them. This statement
alone belies the efficiency of the equipment. Efficiency in a gear
type requires the ability to routinely target one species or specific
size of that species while avoiding the catch of another. Neither
of these gear types has been able to stand this test.
My purpose in this paper is to discuss the history and future of
harpoon swordfishing. I pointedly leave the discussions about the
obviously unacceptable levels of by-catch and discarded catch associated
with these gears to others.
THE WRITING IS ON THE WALL
Chile - An object lesson for the California/Mexico
near shore fishery.
The boom-bust scenario has been played out again and again in swordfishing
all over the world as is well known. The current collapse in the
Chilean fishery is one that parallels the Southern California/Mexico
situation closely enough to deserve special note. At first it was
a highly selective harpoon fishery that exported its' swordfish
to the United States. As in California, harpooning swordfish in
Chilean near shore waters has been documented as being practiced
for hundreds, if not thousands of years.
FIGURE 6

NOTE ON DATA - FIGURE 6
There are hard data points for 1984,1991, 1995 and 1996. There
are approximate data points for 1997 and 1998. The rise and fall
of the data between 1984 and 1995 was shown as linear due to a lack
of precise data. However, this rise and subsequent fall are both
described as "steady" by NMFS Swordfish Links, Latin American
Swordfish Page, Chilean summary, 1/18/2000. The rise in landings
after 1995 reflects a change to fishing outside of the Chilean 200
mile EEZ and off other countries while still landing in Chile.
When man's inventiveness came into play and drift gillnets were
put to sea in 1982, Chile became a major player in the world swordfish
export market, again shipping much of its product to the U.S. This
driftnet fishery was composed mainly of former harpooners and targeted
the near shore coastal waters. The dramatic success of this fishery
led to the introduction of pelagic longlines in the mid-1980's.
As in California today, Chilean regulations limited the use of longlines
to waters outside of 200 miles. From the start however, as in California
today, the longliners reported catching large quantities of juvenile
fish. The Chilean near shore fishery peaked in 1991 and has been
in a precipitous decline since. By 1995, the international pelagic
longliners were finished working Chilean off shore waters because
they became economically non-viable. Since 1996, former near shore
fishermen now fish pelagic longline gear off other countries.

NOTE ON DATA FIGURE 7
California swordfish landings for all gear types were totaled to
produce this chart comparing the Chilean situation to our own. If
the California numbers are moved six years to the right to create
a ten-year overlap presentation, the comparison is chilling. Only
the numbers are different. Attempts to obtain Mexican landing figures
for this time period to show the California/Mexico totals were unsuccessful.
Prior to the use of drift gillnets beginning in 1978, the Southern
California near shore harpoon fishery for swordfish was viable,
healthy and growing. Further, through the use of spotter planes,
it was evolving into a technically correct model for the selective,
sustainable harvest of swordfish. Drift gillnetting for swordfish
in both California and Mexico has now severely diminished our near
shore stock. With the introduction of a longline fishery off both
California and Mexico (near shore in Mexico), I am convinced that
we are witnessing the final few years, if not months, of this fishery's
viability unless emergency international measures are taken. Ladies
and gentlemen, the crisis is not approaching, it is upon us. A repeat
of the Chilean debacle is on our doorstep! Conservation and management
measures to prevent such an occurrence are needed immediately.
The Bight of California as a swordfishery
The waters of the Bight are unique. They are not, during our summer,
part of the waters of the northeast Pacific, which are fed by the
cold California Current. The Bight is annually washed by a swirling
influx of warm water from the southeast that in turn displaces the
California Current to the west. This annual push is caused by the
northern reaches of the North Equatorial Countercurrent that flows
northwest up the coast from the Gulf of Panama. In late summer and
fall, we know by experience, this push can extend all the way to
the Washington border (Jimmy Cornell, North Pacific Currents, WORLD
CRUISING ROUTES, 1987).
The waters of the Bight and its outer banks were prime groundfish
habitat in the 1960's and `70's. The fishing out of the groundfish
from these banks by gear that was too effective has been well documented,
is now regulated, and hopefully will be rebuilt. Once these stocks
are rebuilt, this habitat will hopefully be managed as the long
term, sustainable fishery it should be. The availability of on-board
infrared sea surface temperature SST charts since the late 1980's
has allowed us, the fishermen, to watch the ebb and flow of the
counter current on an annual basis. By watching this picture change
in late spring we can know exactly when to put our boats to sea
in search of fish. This knowledge has also led us to the question
of why we used to see swordfish all year and now we don't.
It is my theory that once there existed a somewhat stable, resident
population of swordfish on our outer banks and those to the south
of us. Despite the annual cool down of the water, swordfish were
seen in these waters during every month of the year. Many of the
older Harpooners can boast of having harpooned swordfish during
every month of the year. While large numbers were not caught during
the winter months due to weather conditions, a portion of the annual
influx probably stayed because they found food in great abundance.
Again, with the exception of a very few winter sightings, this has
not been the case since the late 1970's. Clearly the explanation
of this lies in the statistical facts presented in the portion of
this paper dealing with landings over the past twenty-five years.
I also believe that this resident population of fish in the Bight
was added to and mingled with, indeed replenished, by the annual
push of warm water and migratory fish. Thus, when the fish moved
inshore with the current change, local harpooners were actually
fishing on a combination of resident and migratory fish. It is obvious
from the graphs that this near shore or resident population, if
it did exist, was greatly diminished by excessive fishing between
1980 and 1990. Since then, the harpooners have been fishing on the
stocks that enter the Bight area from the pelagic migration.
The only alternative to the above theory is that the nearly year
round fishing pressure by the Mexican near shore drift gillnet/longline
fleet coupled with the annual pressure applied by the West Coast
U.S. near shore drift gillnet fleet has resulted in a near collapse
of the West Coast near shore swordfish stock. Placing additional
pressures on the pelagic migration that obviously feeds this West
Coast near shore fishery makes no sense at all.
44 Million Additional Hooks IS NOT The Answer!
The HMS Plan Development Team is currently considering the allowance
of longline fishing within the EEZ in California. This is in addition
to the pelagic longline vessels currently fishing off of California.
The impact of this can only be realized by doing the math.
ASSUMPTIONS:
The 80 or so currently permitted California swordfish drift gillnet
boats are allowed to convert to longline gear and fish within the
EEZ.
They are allowed to fish between August and January (5 months).
Their gear is limited to 25-mile long sets with 1 hook every 300
feet.
They fish 25 days per month.
IMPACTS:
Up to 2,000 miles of gear set any night containing 35,200 baited
hooks.
Each boat will set up to 55,000 baited hooks per season.
Total hooks per year = 4,400,000!
Total hooks over next ten years = 44,000,000!
The primary point to be made here is that some form of sea creature
will eat every one of those
millions of hooks! Which creature is simple, the first one that
finds the bait.
MORE EFFICIENT MANAGEMENT IS REQUIRED
The science is in; the writing is on the wall.
In Chile, a multi-million dollar export fishery for swordfish and
sharks was brought to its knees within twelve years after the unmanaged
introduction of drift gillnets and longlines. Chile is no longer
a much of a factor in the world market. I quote NMFS Swordfish Links,
Latin American Swordfish Page, Chilean Summary, 1/18/00: "Annual
results from the fishery do show the classic indicators of overfishing."
If that is true, what do our dramatically similar results show?
Let the near shore swordfish stocks recover!
It is high time that we humans stop catching every fish in the
ocean just because we can. Nature has repeatedly reminded us that
we are capable of overfishing any region. The scorched earth, strip-mining
approach to fishing must be brought to an end and replaced with
fisheries that are both selective and sustainable. Harpoon swordfishing
is one of these and there are many others. It is apparent however,
that if harpoon swordfishing is to ever be given a chance to show
itself as the model of a traditional, sustainable and profitable
fishery, the near shore stocks in Bight of California and Mexico
must be allowed to recover. This recovery process can only be realized
by enhancing the annual escapement of swordfish into the Bight of
California. The only way to accomplish this is to apply efficient
conservation and management measures to current and future West
Coast near shore, and now, off shore swordfishing efforts. Declining
landings in the harpoon fishery were the first indicator of trouble
in the near shore California swordfishery. The turn-around of this
decline will also be the leading indicator, the bellwether, showing
that recovery has begun.
RECOMMENDATIONS
There are numerous measures available for managing fisheries. Time-area
closures that limit damage to juvenile stocks may be one answer.
Another may be imposing quotas on California based boats in addition
to limiting imports by Mexican based operators in this unique shared
fishery. Further, limited entry to swordfishing must be considered.
Finally, the Council and the HMS Plan Development Team must now
directly and objectively confront and deal with the unsavory problem
of by-catch and discarded catch associated with drift gillnets and
longlines.
In addition to offering the above methods for consideration, the
writer takes the following specific positions:
1. I strongly oppose the introduction of longline gear inside the
U.S. EEZ by anyone for any purpose, experimental or otherwise.
2. I support the immediate, emergency implementation of an observer
program on all U.S. flagged longliners landing fish in California
coupled with the mandatory installation of electronic tracking gear
on these vessels. These two measures should be paid for by a landing
fee or tax on all longline fish landed in or imported into the state.\
3. In place of a quota system for swordfish take, I support the
implementation of a system triggering the immediate shut down of
fishing by any gear type if low landing weight averages are detected
in that fishery. This trigger should occur when the Department of
Fish and Game catch measurements show that thirty percent of the
average landing weight has fallen below 150 lbs dressed in any gear
type. Discarded juvenile swordfish must be measured at sea and their
numbers and weight must be included in this average.
4. I support the establishment of a realistic, total take quota
system for sharks of all species, including discards, that when
reached by any gear type triggers the automatic shutdown of that
gear type for the remainder of that season.
5. I support the establishment of a realistic, total take quota
system for discarded marlin and for sea turtles of all species that
when reached by any gear type triggers an automatic shutdown of
that gear type for the remainder of that season.
6. I encourage the implementation of import restrictions on Mexican
longline swordfish and sharks until the U.S. near shore stocks show
signs of recovery. These management methods penalize no one. Nor
do they prevent anyone from fishing. They do however specifically
target most areas of concern by specifically targeting the offender
on a case-by-case basis. Whatever steps are taken to reverse the
obvious current damage, a rising trend in future harpoon landings
will be the first indicator that a reversal has occurred and the
near shore swordfish population is on the mend. This trend reversal
will only be seen by first preventing a Chilean style devastation
of the off shore pelagic migration which feeds and rebuilds our
near shore fishery and secondly, by enlisting the help of Mexico
in rebuilding our shared near shore stocks.
CLEARLY, SCIENCE MUST PLAY A LARGER ROLE
While researching this paper, I have been constantly reminded that
I am not a scientist and that not enough "Science" exists
to support my conclusions. My conclusions are based upon the numbers
of swordfish and sharks we no longer see and they are backed up
by statistics supplied by government agencies! My suspicions are
that no scientist in any of these agencies has ever simply graphed
out these very compelling statistics. Had this simple thing been
done, the question "what's wrong with this picture?" would
surely have been asked. Maybe that would have lead to some "real
science". I beg the council and every member of the HMS Plan
Development Team to ask that question of the scientific community
now and to have it specifically and "scientifically" answered
prior to the implementation of a severely flawed HMS Management
Plan.
It is quite frustrating to me that yet another swordfishery might
be allowed to collapse before the scientific community decides that
a study is in order. If we change anything in our fisheries management
practices, it must be in the area of providing timely and thorough
science to those charged with creating our fisheries management
plans.
I thank the Council and the members of the HMS Plan Development
Team for the opportunity to present one fisherman's position. I
sincerely hope that my presentation provides you with additional
perspective to assist in your critical work. I welcome and look
forward to your comments.
Sincerely,
Larry E. Mebust
