The
northern stock of Striped Marlin in the Eastern Pacific Ocean
migrates to waters off the Baja's coast during autumn and winter
months for feeding and breeding purposes. These stocks have
been severely over fished. First, in the early 1960s by the
Japanese tuna longline fleet and recently by an Ensenada fleet
of drift gillnetters that started working the Baja coast in
the early 1980s. In the mid 1990s a Mexican longline fleet
also based out of Ensenada became prolific. This fleet consists
of about 50 large drift gillnetters with 2 mile long nets and
about the same number of large longliners using 35 to 70 mile
longlines. Two longliners took 11,743 striped marlin in 9 months
off Magdalena Bay (details below) Add to that a large number
of small vessels called “pangas” that fish the entire Pacific
coast of the Baja with short 3-4 mile longlines and 400 foot
drift gillnets. That's a major longliner or drift gillnetter
every 8 miles from the Mexican border to Cabo. Add to all the
above, approximately 600 licensed and unlicensed sports boats
between the East Cape and Cabo and you start to get an idea
of the magnitude of the problem.
The billfish population in the Sea of Cortez is down about
80% to 90% from pre-industrial fishing levels of the 1960s
paralleling what the recent (Myers/Worm)
report says; what Sea
Watch reported in 1993 and what the
Inter-American Tropical Tuna Commission (IATTC), said at
their 69 th annual meeting in late June 2002, “The striped
marlin are overfished with a current abundance at less than ½ of
the level which would support maximum sustainable yield.” The
average weight of a striped marlin caught in Cabo has gone
from 160 lbs in the mid 1980s to 110 lbs in 2000 to about 100 lbs in 2003.
Some still claim the declines are cyclical, that the fish will return, but
at this level of fishing effort, be assured they will not.
In
Mexico it is illegal to catch any billfish commercially inside 50 miles from
the coast as they are - by chapter 13 Fisheries Law or “Ley de Pesca” - reserved
exclusively for sportfishing. But Mexican longliners and drift gillnetters are
operating on shark permits which allow them to come within 1,000 meters of the
beach and take huge numbers of marlin and other species also reserved for sportsfishing.
Inshore they also have
killed large numbers of turtles,
mammals, seabirds and whales migrating
down the Baja coast. For example two longliners fishing for swordfish
off Magdalena Bay from September 1997 through May of 1998 deployed 472,000 hooks
catching 11, 743 Striped Marlin as incidental catch. The incidental billfish
caught were 80% of the total catch, while the targeted swordfish were less than
3% of the catch (details)
Although drift gillnets and longlines are primarily responsible for the marlin's
dramatic declines, they are not alone. Though most of the major hotels and
The Sportfishing Association of Cabo San Lucas and the East Cape strongly encourage “catch
and release” of all billfish, it is more and more common to see the fleet captains
and deckhands with an ice chest stuffed with marlin. The going rate for an
illegal marlin paid by restaurants and markets is $75.00 per marlin. In the
1970s there were less then 25 sports fishing boats out at anytime from Cabo
to the East Cape. Now there are about 600 registered boats.This doesn't include
the commercial panga fleet, which also often fishes for and takes the marlin
illegally.
From 1994-2001, SeaWatch interviewed approximately fifty-five Mexican and
American fisherman. Those fisherman, who had been working in the Sea of Cortez
for the last twenty to thirty years report a severely depleted sea.(click
for details) The
anecdotal data collected in these interviews mirrors the
recent study by Myers and Worm , which shows that within 10
years of the start of commercial exploitation, a fishery is reduced by about
90%.
The people who fish daily in the oceans know when sea life disappears. Their
job requires them to look carefully for signs of fish in the oceans. When those
signs disappear, it is the fisherman, not the scientists who notice first.
For the last twenty five years in Mexico the scientists and fishery management
agencies have been strongly influenced by commercial interests, and thus refuse
to acknowledge the true depletion of the fisheries lest they offend their benefactors.
Meanwhile politicians call for new studies to establish “baseline data” but
the baselines no longer exist. As Meyers and Worm confirm in their report, “Management
schemes are usually implemented well after industrialized fishing has begun
and only serve to stabilize biomass at current low levels.”
Today, fish stocks in the Sea of Cortez are down 80%-90% from thirty years
ago. As Dr. Russell Nelson observed fishing
interests “have attempted to achieve maximum harvests in the face of
stock biomass declines with little regard to future sustainability.”
If gillnets and longliners are not removed from the Sea of Cortez immediately,
there is no chance for recovery.
Mexico must implement a sound management plan based on a candid acknowledgement
of the present depletion of the sea. That plan must include:
1.- Enforce the 50 mile and the core management area no take zones,
which are the feeding and breeding waters off the Baja coast out to the Revillagigedo
Islands, by implementing immediately
VMS.
2.- Remove drift gillnets immediately from all Mexican waters (in
the EEZ)
3.- Place a No-Fishing Moratorium on longliner permits until available
scientific information (national and international) is reviewed and environmental
impact studies show if it is true that sufficient fish stocks are available.
Then and only then allow limited fishing with the restrictions similar to those
that longliners in North America have to comply with, including
VMS and staying outside
50 miles and out of the core management areas and other designated commercial
closed zones.
4.- Start Guardianes del Mar which
is a program similar to a State Fish and Game Department. Modeled after existing
Federal law, Guardianas del Mar brings together Mexican Federal and State Government
offices that deal with fisheries management and enforcement. This project currently
being put together in B.C.S would be jointly financed and overseen by the civilian
population.
You must start with people understanding that there is a rule of law in the
Sea of Cortes. There is none now.
