    The Economic Argument Against the California Driftnet Fishery

    econ-report-cover

    The California driftnet fishery has an overall negative impact on our economy because it costs more to manage the fishery than the wealth that is created from the fishery.

    Taxpayers pay for observers and regulators for fisheries to protect public marine resources. Because driftnets are inherently destructive, tight regulation is necessary to ensure that the fleet complies with U.S. and California law and that the fishery does not devastate the public marine resources of the California coast. The cost of regulation would substantially decrease if the California swordfish fishery used more sustainable fishing gear instead of driftnets.

    The catch from the California driftnet fishery peaked in the 1980s and has been steadily declining.1 According to the California Department of Fish and Wildlife, the California driftnet fishery landed 135,000 pounds of swordfish in 2013, valued at $585,000.

    Sea turtles are among the most ancient of living species, having evolved during the age of the dinosaurs some 110 million years ago. Today, seven species survive. All sea turtles found in U.S. waters are listed as ‘endangered’ or ‘threatened’ under the U.S. Endangered Species Act. Importantly, the two main species killed by the driftnet fishery – the Pacific Loggerhead and the Leatherback – are both endangered and in imminent peril of extinction.

    Sea turtles reach a large size as adults, making them immune to most natural predators and allowing females to produce thousands of young over their long reproductive lives, despite the fact that relatively few will survive to adulthood. This successful evolutionary strategy has worked for millions of years, but is now being short-circuited when adult sea turtles are killed in industrial fishing gear. Sea turtles are now endangered worldwide.

    Coho Spawning Population

    SPAWN, National Park Service, and Marin Municipal Water District (MMWD) are part of the team counting and monitoring the numbers of fish migrating to their natal streams to spawn and lay eggs. SPAWN monitors these fish in the San Geronimo Valley’s small tributaries, specifically Arroyo, El Cerrito, Barranca, Montezuma, Larsen, Willis Evans, Woodacre, and North Fork San Geronimo creeks. Below is our brief overview of the data collected this spawning season in our watershed.

    This season a total of 271 coho redds were observed throughout our watershed.

    For the first time in recent years, the timing and amount of rainfall allowed our coho salmon to make their way into some of San Geronimo’s smaller tributaries. SPAWN documented a total of 30 coho salmon redds (nests) this season in the San Geronimo tributaries, but they were all in just two of the eight tributaries, with 17 redds recorded in Arroyo Creek, and 13 redds in Woodacre Creek.

    These two small tributaries accounted for 30 percent of the total 99 spawners for the San Geronimo Valley and 11 percent of all the redds in the Watershed (which includes Lagunitas Creek, Devils Gulch, Cheda Creek, San Geronimo Creek and all seven San Geronimo tributaries).

    Coho graph

    While media reports have stated the run count of 271 is the best in ten years, what may be more biologically relevant is the fact that the spawning numbers for this year-class are below its 311 average.

    These fish live and die in a three year period, so there are basically three distinct year-class populations. If you look at the year-class that spawned this year, and compare it against those 3 years ago, six years ago, nine years ago, etc., it is below average. Scientists do not normally try to draw conclusions about population trends from a single year’s data point.

    The stated U.S. National Marine Fisheries Service recovery goal is to bring the runs of these imperiled fish to average 2,600 adult fish each and every year.

    In Marin, the species is on the verge of extinction, no matter how the numbers are spun. This year, our creeks and tributaries did provide spawning grounds to a few more fish than last year, but more must be done to ensure these fish not only survive but thrive.

    As scientists are warning that our ocean ecosystems are on the verge of collapse, leaders are taking action to rein in the world’s worst industrial fisheries.

    Astonishingly, one of those worst offenders is California’s driftnet fishery, (also known as the CA drift gillnet fishery). Currently, the fishery consists of a small fleet of roughly 20 active vessels that set nets the size of the Golden Gate Bridge to drift unattended through our oceans. While the primary targeted commercial species for this fishery are swordfish and shark, these nets entangle everything in their mile-wide path, resulting in high levels of bycatch (unintended catch, most thrown overboard dead or injured).

    Over the past ten years, nearly a thousand air-breathing whales, dolphins, and sea turtles have drowned, while thousands of sharks (that depend on constant movement) have suffocated.

    In the last ten years, an estimated 26,000 sharks overall were caught by this deadly fishery, with nearly 10,000 simply being tossed overboard. The fishery was especially wasteful in its treatment of blue sharks. In the last decade, 8,186 blue sharks were caught, and an astounding 8,180 were discarded. Of those discarded nearly 5,313 were dead. The fishery also caught an astounding 8,000 common thresher sharks (a candidate species for listing under the U.S. Endangered Species Act) and is further jeopardizing shark populations.

    This inherently destructive fishing gear has been banned by the United Nations, on the high seas, by a host of countries, and throughout the United States. California is the last state in the U.S. to allow this fishing method, which has been described as “invisible curtains of death.”

    Essentially, this gear entangles or kills almost everything that becomes entangled, in hopes that some of the thousands of animals caught or killed are swordfish, an expensive luxury product with dangerous levels of mercury. Only one in eight of the animals caught are swordfish.

    Given the tremendous difficulty in enforcing environmental laws for such a destructive fishery, U.S. taxpayers bear the cost of managing this economically marginal fishery for almost no benefit. The end result is that the driftnet fishery is a net drag on the U.S. economy.

Fact Sheets

  • SilkyShark_NestorRomero

    Silky Shark Fact Sheet

    Common Name: Silky Shark

    Scientific name: Carcharhinus falciformis

    Global distribution:
    -One of the three most common pelagic sharks in the world, and most common shark in tropical pelagic fisheries.
    -Present in global tropical waters between latitudes 20° N and S.
    -Inhabits both oceanic and coastal habitat.

    SilkySharkSubBanner

    Facts About Silky Sharks:
    -Name comes from its smooth skin and slim body
    -Commonly reaches a length of 2.5 m (8.2 ft), with a maximum recorded length of 3.5 m (11 ft) and weight of 346 kg (763 lb)
    -An opportunistic predator, feeding on squid, tuna, mackerel, sardines, groupers, and snappers.

    Population Decline
    International consensus agrees on the precarious state of the population by overfishing, judging by the low in relative abundance and reducing size of specimens caught in fisheries where data exist.

    -Total annual catch reported to the Food and Agricultural Organization fell steadily from 11,680 tons in 2000 to 4,358 tons in 2004
    -Declines of some 90% in the central Pacific from the 1950s to the 1990s
    -60% decline off Costa Rica from 1991 to 2000
    -91% decline in the Gulf of Mexico from the 1950s to the 1990s
    -85% decline (for all large requiem sharks) in the northwestern Atlantic from 1986 to 2005
    -The silky shark fishery off Sri Lanka reported a drop from a peak catch of 25,400 tons in 1994 to only 1,960 tons in 2006

    IUCN Red List Category: Vulnerable in the Eastern, Central, and Southeast Pacific, and Northwest and Western Central Atlantic. Near Threatened on a global scale.

    Convention on Migratory Species Status: Listed under Appendix II in November of 2014, and listed under Annex I of the Memorandum of Understanding (MoU) Migratory Sharks in February 2016.

    Threats
    -Greatest numbers of silky sharks are caught incidentally by tuna and mahi mahi longline and purse seine fisheries throughout its range, particularly those using fish aggregating devices.
    -Most-caught species in longline fisheries in the Eastern Tropical Pacific, constituting up to 90% of the total catch of sharks.
    -Large numbers of silky sharks caught by commercial and artisanal multispecies shark fisheries operating off Mexico, Guatemala, El Salvador, Costa Rica, the United States, Ecuador, Spain, Portugal, Sri Lanka, the Maldives, Yemen, and Côte d’Ivoire.
    -Fins from an estimated 0.5 to 1.5 million silky sharks are traded globally per year; it is the second- or third-most common species auctioned on the Hong Kong fin market, which represents over half the global trade
    -The meat (sold fresh or dried and salted), skin, and liver oil may also be used
    -Predominant source of dried shark jaw curios sold to tourists in the tropics

    Recommended conservation actions
    -The IATTC should enact the recommendations of its Scientific Advisory Committee to reduce and limit the catch and implement 3-month fisheries closures
    -CITES should list the Silky Shark on Appendix II and trigger measurable action plans to reduce mortality and reverse population decline
    -Reduce fishing effort in the Eastern Tropical Pacific
    -Release sharks alive

    What you can do
    Sign our petition calling on the Inter-American Tropical Tuna Commission to implement 3-month closures and improve gear types.

    Make Your Own Sea Turtle Costume!

    Materials:

    • 1 or 2 large cardboard box/cartons. I get these from appliance stores or bicycle shops
    • 8 1-2″ wide strips of fabric about 1-2 ft. long. I got fabric from a thrift shop, old sheets or bed spreads work well for this (try to find a color that is similar to your turtle).
    • Quart of exterior house paint (possibly some Z-prime for an undercoat depending on quality desired).
    • A heavy-duty stapler with 3/8″ staples. Stapler needs to be the long handled heavy duty type. Staples longer than 3/8″ tend to bend and come back through the cardboard creating a sharp, snagging hazard.

    Cocos Island Gallery

    Cocos Island National Park in Costa Rica is known worldwide as an ocean haven for spectacular sharks, rare sea turtles, whales and abundant marine wildlife. But even World Heritage status has not stopped commercial fishers from invading these treasured waters.

    Turtle Island is working to demand that Costa Rica protect Cocos Island National Park create a protected area that connects all the way to Ecuador’s waters, northeast of the Galapagos Islands. These two nations could create one of the world’s largest protected ocean zones, and save the endangered leatherback turtle from extinction.

    And now you can help us! We welcome experienced divers who want to participate in our ongoing research to help tag and track sea turtles and sharks in the Cocos Islands. You will get hands-on opportunities to capture turtles and attach satellite and acoustical transmitters and to tag and photograph hammerhead sharks underwater.
