Fact-based Fisheries Management and MPAs (or not)

Richard,
Thanks for asking for the facts on the status of fish and the need, or not, for MPAs.
First, I discuss the environmental rationale for resisting the MLPA (Marine Life Protection Act) as it is being implemented. Next, I post information on current fisheries management, fisheries management tools, the stock rebuilding program and status of stocks (see below).
Background—Science responds to new information
As you know by now, Dr. Boris Worm has joined Dr. Ray Hilborn and 19 other renowned international scientists in a July, 2009, article in Science, “Rebuilding World Fisheries,” refuting Worm’s earlier prediction of world ocean fishery collapse by 2048. Hilborn mentions that many earlier studies were based on fish landings, which are not a good assessment of stocks. The article is one of hope, and suggests that the best combination of fisheries management tools is the combination we are already using on the West Coast.
“Most often, it appears that a combination of traditional approaches (catch quotas, community management) coupled with strategically placed fishing closures, more selective fishing gear, ocean zoning, and economic incentives holds much promise for restoring marine fisheries and ecosystems” (Worm, 2009). We have these in place already, and they are working.
“The regions that have made the greatest advances toward recovery are California, New England and Iceland, but also we see signs of recovery in other regions around the world.” –Dr. Boris Worm. (Worm, August, 2009).
Environmental Reasons for Resisting the MLPA
Far from opposing government management of fisheries, most fishing folks support, participate in and certainly comply with current management through the Pacific Fisheries Management Council (PFMC). The MLPA process, however, is taking the fishery/environmental community’s staff resources away from real ocean protection. The MPAs don’t ‘protect’ the ocean from land-based pollution, offshore oil and aquaculture development, or ocean acidification—they only stop fishing and gathering. They don’t protect migratory and pelagic species or help the spawning/rearing habitat for anadromous species like salmon. They do restrict local gathering of local seafood, thus undercutting the strongest supporters of ocean protection. There are additional environmental justice issues, such as Native American subsistence rights and conflict of interest allegations in the MPA decision-making process.
Legislators can apparently do little at this time to “stop or de-fund” the MLPA, a 1998 state law, implementation of which is funded by the Packard Foundation through its Resources Legacy Fund Foundation in partnership with the California Resources Agency. Fishery/environmental interests are forced to participate to 1) minimize the damage to local economies, and 2) retain legal standing for any future litigation. Participation is being done under protest.
A legislative effort to investigate the buying of government by private foundations was derailed by Senate pro tem Darrell Steinberg. The Governor replaced the swing vote on the Fish and Game Commission with his head of the BRTF, Don Benninghoven, two days before the 3-2 vote on the North Central Coast MPAs (Pt. Reyes to Alder Creek, north of Point Arena.) Commissioner Mike Sutton is being investigated for conflict of interest for his foundation-backed research organization paycheck. The BRTF changes the rules for the stakeholders at will. (“Reduce the number of proposals.” “Wait, don’t throw out that one!”) Stakeholders participate in months of meetings, only to have their work overturned by the BRTF “preferred alternative” before the Commission vote.
Current Fisheries Management
I assume you are concerned about groundfish (rockfish, flatfish, roundfish), as they are the most sedentary fish that are most likely to receive any help from closed areas. Area closures are not the best management tool for pelagic or migratory fish that move around. All rockfishing is constrained by the stock rebuilding programs for certain overfished species (see below).
There are huge areas already closed to rockfish fishing: The Rockfish Conservation Area (RCA) closes waters for all bottom fishing from 20 fathoms out to 100 fathoms (basically between 2 and 10 miles offshore). The RCA closes about a third or 200 square miles of state waters. Besides the RCA, there are large cowcod closure areas.
Trawl fishing (with drag nets) is outside 100 fathoms; none is inside state waters, the area of the state MPAs. A trawl buyback in 2002 reduced the trawl fleet to about 20 active boats in California, and that number is expected to be reduced more by the groundfish Individual Fishing Quotas that have gone into effect. Rockfish fishing in state waters is by hook and line for sport and commercial.
Fisheries Management Tools
By visiting the PFMC website, you can find out the many tools that are currently being used to manage rockfish and flatfish—or any other ocean fish. The Council considers outside proposals.
Management tools currently in use are: Landing limits, mesh size regulations (for net or trap fisheries), trawl modifications (area limits, footrope size limits to prevent operation in reef areas, no roller gear, selective flatfish gear that allows rockfish to escape), quotas (Optimum Yields), escape ports and biodegradable panels (to prevent ghost fishing), size limits, bag limits (per day for sport), time/area closures, Essential Fish Habitat closures (NOAA , 2009. ), effort control (limited entry and more), and gear restrictions (number, size, and shape of hooks, traps and pots.) In-season adjustments are made throughout the year as needed.
Stock Rebuilding Program and Status of Stocks
“Overfished” for rockfish is defined by NMFS as being below 25% of estimated (spawner) virgin biomass. Recovery to fishable status is placed at 40% of same.
There are 64 species of rockfish off California. Rockfish are long-lived, late maturing, and slow-growing species. These traits make them particularly vulnerable to overfishing. Seven species of West Coast groundfish are currently considered “overfished” by NMFS. They include widow rockfish, canary rockfish, yelloweye rockfish, darkblotched rockfish, bocaccio, Pacific ocean perch, and cowcod.
Pacific whiting was declared overfished in 2002 and subsequently removed from the overfished list in 2004. Lingcod were also declared overfished in 1999, but were rebuilt and taken off the overfished list in 2005 (Groundfish, 2007).
Widow rockfish is expected to recover by next year, according to John DeVore of the PFMC, staff officer for the Groundfish Management Team and the Groundfish Advisory Subpanel (DeVore, 2009).
“Overfishing” is defined as an annual catch higher than the “acceptable biological catch” (ABC). “Very little overfishing [has recently occurred] on the west coast, with only sablefish [black cod] subject to overfishing last year. That problem was based on a data error in our catch tracking system that has since been fixed” (DeVore, 2009).
There is currently no overfishing occurring in West Coast fisheries that are within US waters, according to the National Marine Fisheries Service (3rd quarter 2008 report to Congress), .
Two high seas Pacific species that are currently being overfished are yellowfin tuna and big–eye tuna.
MPAs—the wrong tool for the job
Marine Protected Areas have no apparent goal, other than to close the ocean to fishing.
