Pacific Council Gives Preliminary Nod to Two Coastal Sardine and Other Pelagic Species Projects

November 22, 2017 — SEAFOOD NEWS — The Pacific Fishery Management Council last week approved for public review two exempted fishing permits that should help improve coastal pelagic species stock assessments.

Both projects would add more survey work to nearshore areas. Fishermen have identified schools of sardines, in particular, close to shore but accessing them for survey work has been a problem because the sardine season has been closed and NOAA ships cannot access shallow areas. Additionally, both proposals would build on the use of industry knowledge.

The California Wetfish Producers Association research project intends to sample CPS schools in the southern California Bight using aerial spotter pilots with camera systems to fly surveys close to shore and photo-document schools. At the same time, qualified purse seine vessels would capture a subset of the schools identified in the photographs as “point sets.” This would provide a way to address issues identified in the aerial survey methodology review. The survey period is scheduled for late August 2018.

According to the CWPA application, all fish captured, including sardines, would be processed and sold by participating processors, and fishermen will be paid for their catches at the usual rates. Aside from the sale of fish, processors would not be compensated for the extra labor they will incur in weighing and fully sorting each school individually and documenting species composition by school, rather than the normal procedure of offloading the entire catch and documenting by load.

“We strongly support these EFP projects to improve the accuracy of stock assessments. It should be noted that 70 percent or more of the CPS harvest in California occurs in the area inshore of NOAA acoustic surveys,” CWPA Executive Director Diane Pleschner-Steele said. “We are grateful to the California Department of Fish and Wildlife and Southwest Fishery Science Center for their help and recognition that surveying the nearshore is a high priority research and data need.”

Pacific Seafood’s Mike Okoniewski presented the Westport, Wash.-based West Coast Pelagic Conservation Group project to both the Council and the Scientific and Statistical Committee. The project is designed to provide supplementary data collection and additional sampling techniques for areas nearshore of the proposed 2018 NOAA/Southwest Fisheries Science Center acoustic-trawl survey, according to the group’s application. This research off of Washington and Oregon would continue and expand the 2017 collaborative effort in 2018 so that samples of CPS for species composition and individual fish metrics may be obtained through purse seine operations, according to Council documents.

Sampling would be done at the same general time and nearshore areas as the NOAA survey, the applicants stated. The coastal pelagic species (CPS) that will be retained in small amounts (e.g. 5kg to 25kg) for sampling will be dip-netted sardines, anchovies, and mackerel(s). The sample fish will be frozen and retained for identification and biological measurements to be performed by NOAA.

But unlike the southern EFP, no fish will be harvested for commercial purposes. Wrapped schools would be released alive, the applicants said.

“This collaboration will continue to support the already commendable efforts of the scientists, balancing it with industry knowledge of the fishing grounds,” Okoniewski said.

Both EFPs will add to current survey and stock assessment work, providing more robust data for the fisheries in the future. The Council’s Scientific and Statistical Committee and Coastal Pelagics Species Management Team supported the EFPs and suggested minor technical changes to each; both applicants plan to incorporate those suggestions prior to the Council’s and NMFS’ final approval in early 2018.

“The CPSMT recognizes the value of the EFP research proposed by both groups to improve CPS stock assessments by obtaining data that has not been attainable by other means,” the CPS Management Team said in its statement.

The Coastal Pelagic Species Advisory Subpanel also supported the projects. “[We are] encouraged that forward progress is now being made to develop effective survey methods for the nearshore area,” the panel said in its statement. “The CPSAS thanks CWPA, WCPCG and especially the SWFSC for acknowledging the data gaps in current surveys and helping to provide support and funding for cooperative surveys that will hopefully improve the accuracy of future CPS stock assessments.”

Pelagic survey highlights NOAA’s growing collaborative relationship with industry

August 30, 2017 — Earlier this year, officials with the National Oceanic and Atmospheric Administration used the Lisa Marie, a private fishing boat, to collect data for its annual coastal pelagic species survey. The move was part of an effort to increase collaboration between the public and private sectors.

Earlier this summer as officials with the U.S. National Oceanic and Atmospheric Administration completed work on an annual survey of coastal pelagic species (CPS) in the Pacific Ocean, they received some assistance from a new source: the private sector.

Not only were representatives from the West Coast seafood trade industry on board a federal vessel for five days while survey samples were taken, but one fisherman allowed NOAA officials to outfit his boat with equipment to survey more shallow waters near the coastline. The collaborative venture marked a milestone in a public-private dialogue that’s been going on for years.

The CPS survey collects data primarily on Pacific sardines, said Kristen Koch, the acting science and research director of NOAA’s Southwest Fisheries Service Center in La Jolla, California, but it also includes observations on other CPS fish such as northern anchovy and jack and Pacific mackerels. Typically, officials use the Reuben Lasker, a NOAA vessel, to conduct the survey. However, private sector representatives felt the government was missing out on some key data in their work.

Government leaders welcomed the idea to get more data to fill in the gaps they also sought to fill.

“Data is like gold to us,” said Koch. “If we can collect more of the kind of data we need, it improves the precision of our assessments of these species.”

Fishermen See ‘Science in Action’ Aboard NOAA Survey Ship

August 18, 2017 — Each spring and early summer, scientists set out along the West Coast aboard NOAA vessel Reuben Lasker to survey coastal pelagic species, or CPS, which includes small schooling fish such as northern anchovy, Pacific sardine, and jack and Pacific mackerels.

This year, with the help of West Coast fishermen, the scientists tested a new approach to extend their reach into nearshore waters to improve the accuracy of the survey results. The collaboration involved the fishing vessel Lisa Marie, of Gig Harbor, Washington, and brought two commercial fishermen aboard Lasker for an inside look at NOAA Fisheries surveys that inform stock assessments and guide decisions on how many fish can be caught by West Coast fishermen.

The idea emerged years before when the then-Director of NOAA’s Southwest Fisheries Science Center in La Jolla, California,  Cisco Werner, along with Deputy Director Kristen Koch and Fisheries Resources Division Director Gerard DiNardo, discussed the potential collaboration with Mike Okoniewski of Pacific Seafood and Diane Pleschner-Steele of the California Wetfish Producers Association.

Werner has since been named Chief Scientist of NOAA Fisheries.

The Magnuson-Stevens Fishery Conservation and Management Act requires NOAA Fisheries to use the best available science to help managers set catch limits and prevent overfishing. Annual surveys, using echosounders to detect and measure the abundances of CPS populations off the coasts of California, Oregon, Washington, and Canada’s Vancouver Island help fulfill this mandate. NOAA Fisheries also uses trawl catches, and fish-egg samples to help gauge fish reproduction and population trends.

“Acoustic-trawl surveys are our principal tool for monitoring the various species and determining how their abundances, distributions, and sizes are changing,” said David Demer, the Chief Scientist of the survey and leader of the Advanced Survey Technologies Group at Southwest Fisheries Science Center in La Jolla. “The surveys are very rigorous because they’re very important to our mission.”

Oceana Files Legal Challenge to Northern Anchovy Catch Limit

WASHINGTON (Saving Seafood) — November 29, 2016 — Last week, environmental group Oceana filed a lawsuit alleging that a recent National Marine Fisheries Service (NMFS) specification rule allows commercial fishing for northern anchovy at levels that threaten the anchovy population and the marine ecosystem. The complaint was filed against the NMFS, Secretary of Commerce Penny Pritzker, and the National Oceanic and Atmospheric Administration (NOAA) in the District Court of Northern California.

The specification rule in question, announced October 26, 2016 under the Coastal Pelagic Species Fishery Management Plan, set an annual catch limit (ACL) of 25,000 metric tons for the central subpopulation of anchovy. In its lawsuit, Oceana claims that the NMFS did not articulate the scientific basis for this ACL, did not base the ACL and related management measures on best available science, and did not explain how it would prevent overfishing and protect the West Coast marine ecosystem’s food web.

In doing so, Oceana claims that the rule violates the Magnuson-Stevens Fishery Conservation and Management Act and the Administrative Procedure Act. The complaint claims that the northern anchovy population has severely declined since 2009, and that northern anchovy are “one of the most important forage species” in the California marine ecosystem.

“The Fisheries Service’s actions and failures to act have harmed Oceana’s members’ interest in rebuilding and maintaining a healthy and sustainable population of northern anchovy and a healthy ocean ecosystem,” said the lawsuit, which was filed by lawyers from Earthjustice on Oceana’s behalf. “This harm will continue in the absence of action by the Court.”

Fisheries scientists to address flaws in past forage fish research

WASHINGTON (Saving Seafood) – May 2, 2016 – Dr. Ray Hilborn, a marine biologist and fisheries scientist at the University of Washington, has launched a new initiative aimed at addressing key issues surrounding forage fish science and the impacts of forage fishing on predator species. Dr. Hilborn’s Forage Fish Project is one of several scientific efforts occurring in the next few months to expand the existing body of scientific research on forage fish.

Comprised of 14 renowned fisheries scientists from around the globe, the Forage Fish Project held its inaugural conference last month in Hobart, Australia, where it identified shortcomings in the existing forage fish research. Specifically, it found several issues with work produced by the Lenfest Forage Fish Task Force, whose April 2012 report, “Little Fish, Big Impact,” concluded forage fish are vulnerable to overfishing, among other findings.

The Forage Fish Project, which includes two members of the Lenfest Task Force, began work to address these flaws, with the goal of producing an accompanying study later this year.

In Hobart, Project members found that most of the models used in previous forage fish studies, like the Lenfest Task Force report, left out factors such as the natural variability of forage fish stocks, and the extent of size overlap between fisheries and predators. The group also found multiple indications that the Lenfest study greatly overstated the negative impact of forage fishing on predator species.

“Most [food web] models were not built with the explicit intention of evaluating forage fish fisheries, so unsurprisingly many models did not include features of forage fish population biology or food web structure that are relevant for evaluating all fishery impacts,” according to minutes from the Hobart meeting.

Two upcoming fishery management workshops will also evaluate forage species on the East and West Coasts of the U.S., the first organized by the Southwest Fisheries Science Center and the Pacific Fishery Management Council. The workshop, which will be held in La Jolla, Calif., from May 2-5, will focus on how to improve stock assessment methods for northern anchovy and other coastal pelagic species. Attendees will evaluate model-based assessment approaches based on routinely assessed pelagic species from around the world, consider non-assessment approaches to estimate fish stocks, and develop recommendations for how the SWFSC should evaluate coastal pelagic fish stocks in the future.

A similar forage fish workshop will be held May 16-17 in Portland, Maine. This workshop will focus on Atlantic herring, with the goal of establishing a rule to specify its acceptable biological catch (ABC), the recommended catch level for any given fish species. An effective ABC rule will consider the role of Atlantic herring in the ecosystem, stabilize the fishery at a level that will achieve optimum yield, and address localized depletion in inshore waters.

Ultimately, these various forage fish workshops and projects are striving to use the best available science to update previous research and determine sound management practices for forage species.
