Lots of Reasons to Decline Lenfest’s Menhaden Reference Points, Says Beaufort Lab Scientist

November 10, 2017 — SEAFOOD NEWS — Joseph Smith is a retired marine scientist formerly with the NOAA Southeast Fisheries Science Center, Beaufort Laboratory, National Marine Fisheries Service. He was the principal investigator for the Menhaden Program with the Sustainable Fisheries Branch, where he supervised the collection of fishery-dependent data for the Atlantic and gulf menhaden purse-seine fisheries. He has written an op-ed on the debate before the Atlantic States Marine Fisheries Commission on reference points for the Menhaden stock. Lenfest, whose 2012 book on Forage Fish sparked a huge debate, is pushing for a reference limit that would shut down fishing if the menhaden stock nears 40% of its unfished level. Smith argues that this approach does not work for Menhaden, as there is no stock size recruitment relationship, and for that reason, no evidence that fishing based around current reference points is not fully sustainable for ecosystem functions.

His letter is below:

Since the Lenfest Forage Fish Task Force issued their publication, “Little Fish, Big Impact” in 2012, there has been an enormous focus on “forage fish” – small schooling stocks important food for larger marine predators. Atlantic menhaden, a stock on which I worked for over thirty years as a scientist for the National Marine Fisheries Service, is now a subject of this focus.

Despite being abundant and widely distributed, the debate over menhaden centers on a looming decision by the Atlantic States Marine Fisheries Commission over how to adopt reference points that incorporate menhaden’s role in the ecosystem. At the broadest level, this goal is impossible to argue against.

The pending question is to how best to get there. Reference points must make biological sense to ensure a sustainable menhaden population, along with sustaining the coastal communities that the fishery supports. Indeed, the Commission’s scientific advisors are currently working on ecological reference points, or ERPs, specific to menhaden and their ecosystem. There should be no debate that Atlantic menhaden-specific ERPs are the most desirable.

The real issue is how to manage the stock in the interim. Currently, menhaden are managed to sustain a high level of annual egg production. While not typical, this works for menhaden because there is a very weak relationship between the number of spawners and population size.

Annually, the stock produces trillions of eggs, but their development into larvae and then young menhaden depends on factors such as winds, currents, water temperature, salinity, and predation. Historically, there are instances where relatively large spawning stocks of female menhaden produced few young recruits to the population, while relatively small spawning stocks produced large numbers of young recruits.

This lack of what is known as a classic “stock-recruit relationship” is important to understanding the current debate because the “rule of thumb” which the Lenfest group developed for forage stocks is premised on it. Lenfest devotees urge the Commission to adopt ERPs premised on maintaining 75% of an unfished population, and allowing no fishing when the stock falls to about 40% of this level.

Of course, to manage a stock for a predetermined level of abundance, there has to be some relationship between fishing effort and stock size; this also does not exist for the menhaden fishery.

More disconcerting is that the Lenfest 75%/40% approach may involve harvest cuts of up to 50,000 metric tons from current levels. If the stock is determined to be only about 46% of unfished levels, the fishery would be very close to a shutdown. Looking forward, if Lenfest advice is adopted and harvest levels curtailed in the near-term, what is the relevance of harvest advice which may evolve in a few years from the current menhaden-specific ERP work? If the latter studies endorse appreciable increases in harvest, this could create a climate of regulatory “whiplash”, a situation which fisheries managers I believe should avoid.

The crux of the debate, then, is whether one believes there needs to be a reduction in menhaden catch to maintain a healthy ecosystem or whether the current, conservative management regime is working. In my view, the system has worked well for the stock, the fishery, and ecosystem, particularly over the past decade.

The wisest alternative to “rule of thumb” management advice is maintaining the current reference points which are specific to Atlantic menhaden. I support the current single‐species reference points until the ERPs are developed by the Commission’s scientists. Next year in 2018, the ERP working group will hold data workshops to select and standardize data that will be used as model inputs; this includes data that pertains not only to menhaden abundance, but also the abundance of bluefish, striped bass, and other predator species.

The ERP group is comprised of state and federal scientists who have spent a significant portion of their careers working on ERPs for menhaden. The Commission sent them down this path several years ago. Stay the course, let them finish their work, and present their results as planned in 2019. The menhaden population currently has a broad age structure with six or more age classes represented, the population is expanding into the northern half of its range, and recruitment in recent years is above average – the sky will not fall on the menhaden population in the interim. Given menhaden’s current stock status, allowable catches could increase 10% with no discernable impact to the population.

In the end, the Commission should follow the advice of its scientific advisors who have indicated that the Lenfest approach is not a good fit for menhaden. The current approach of protecting spawning potential has worked well. There is no obvious biological or scientific reason to abandon it now.

Menhaden Fisheries Coalition Analysis Finds 92 Percent of Atlantic Menhaden Already Left In Water to Serve Ecological Role

Analysis Challenges Arguments That Interim Ecological Reference Points Are Urgently Needed

An analysis finds that 92 percent of Atlantic menhaden are left in the water to serve their ecological role. A high quality version of this infographic is available by clicking on the image.

WASHINGTON – November 9, 2017 – The following was released by the Menhaden Fisheries Coalition:

A new analysis from the Menhaden Fisheries Coalition (MFC) finds that current management leaves 92 percent of Atlantic menhaden to serve their ecological role as forage for predators. The analysis is based on data from the Atlantic States Marine Fisheries Commission’s (ASMFC) 2017 update stock assessment of Atlantic menhaden. The MFC has produced an infographic illustrating this analysis, which is available here.

In recent weeks, numerous ENGOs and recreational fishing groups up and down the Atlantic Coast have published articles and op-eds arguing that menhaden are in dire need of greater protection. These groups include the Pew Charitable Trusts, the Chesapeake Bay Foundation, the American Sportfishing Association, and local activists from coastal states like Rhode Island and New Jersey. However, the MFC’s analysis challenges the assertion that fisheries take too many menhaden, and makes clear that the vast majority of fish are already left in the water to fulfill their ecological role.

The analysis tracks an average menhaden year class through its full life cycle. It finds that two-thirds of juvenile menhaden (younger than age 1) are either consumed by predators or die of natural causes. These juvenile menhaden are the preferred forage for predator species and are not targeted by the fishery, which takes less than 1 percent of these fish.

Over half of the menhaden that survive to age-1 are allocated to the ecosystem to be eaten by predators such as striped bass and marine birds or die of natural causes. Only 8 percent of age-1 menhaden are harvested by the fishery.

The menhaden fishery largely harvests menhaden over the age of 2, but even for this age group, it only harvests about 40 percent of fish. Overall, just 8 percent of a menhaden year class is harvested by the fishery. The overwhelming majority of fish – 92 percent – are not impacted by the fishery.

This MFC analysis is an update of a previous analysis that was based on the ASMFC’s 2015 benchmark stock assessment of Atlantic menhaden. That analysis was reviewed by the ASMFC last fall. Both the 2015 benchmark assessment and the 2017 update assessment found that Atlantic menhaden is neither overfished nor experiencing overfishing.

‘Rule of Thumb’ Management Approach Is Wrong For Forage Fish, Dr. Ray Hilborn Tells U.S. Senate Subcommittee

WASHINGTON (Saving Seafood) – October 31, 2017 – At a hearing of the U.S. Senate Commerce Subcommittee on Oceans, Atmosphere, Fisheries and Coast Guard last week, respected fisheries scientist Dr. Ray Hilborn testified that fisheries managers “can do better than a one-size-fits-all” approach to managing forage fish. He also said there was “no empirical evidence to support the idea that the abundance of forage fish affects their predators.”

Dr. Hilborn’s comments came in response to questioning from Sen. Roger Wicker (R-MS) about whether fisheries managers should manage forage fish according to a “rule of thumb” approach, where fisheries are managed according to a set of broad ecological and management principals, or a “case-by-case” approach, where management is guided by more species-specific information.

Dr. Hilborn, a professor at the University of Washington’s School of Aquatic and Fishery Sciences, was part of a team of top fisheries scientists that recently examined these issues, as well as what effects fishing for forage fish species had on predator species. Their research indicated that previous studies, like a 2012 report from the Lenfest Forage Fish Task Force, may have overestimated the strength of the predator-prey relationship.

Before the hearing, Dr. Hilborn spoke with Saving Seafood about his research and his message for lawmakers.

“It’s very clear that there really are no applicable rules of thumb, that every system is independent [and] behaves differently, and we need to have the rules for each individual forage fish fishery determined by looking at the specifics of that case,” Dr. Hilborn told Saving Seafood.

He also discussed his team’s finding that forage fish abundance has little impact on their predators. They looked at nearly all U.S. forage fish fisheries, including the California Current system and Atlantic menhaden, and concluded that predator species generally pursue other food sources when the abundance of any one forage species is low.

“The predators seem to go up or down largely independent of the abundance of forage fish,” Dr. Hilborn said, adding, “For Atlantic menhaden, for their major predators, the fishery has reasonably little impact on the food that’s available to them.”

Another key message Dr. Hilborn had for the Subcommittee was that fisheries managers must determine what they want to accomplish so that scientists can advise them accordingly.

“The time has come to refocus our fisheries policy on what we actually want to achieve because rebuilding is only a means to an end,” Dr. Hilborn told Saving Seafood. “Do we want to maximize the economic value of our fisheries? Do we want to maximize jobs? Do we want to maximize food production?”

In his testimony, Dr. Hilborn praised U.S. fisheries policy that has “led to rebuilding of fish stocks and some of the most successful fisheries in the world.” He attributed this success to a variety of factors, including funding of NOAA, regionalizing fisheries management decisions, and requiring managers to follow science advice. As a result, overfishing should no longer be the top priority for fisheries managers, he testified.

“The major threats to U.S. fish stock and marine ecosystem biodiversity are now ocean acidification, warming temperatures, degraded coastal habitats, exotic species, land based run off, and pollution,” Dr. Hilborn testified. “Overfishing remains a concern for a limited number of stocks but should not continue to be the most important concern for U.S. federal fisheries policy.”

The hearing was the latest in a series examining reauthorization of the Magnuson-Stevens Fishery Conservation and Management Act, the nation’s supreme fisheries law. It was organized by subcommittee chairman Sen. Dan Sullivan (R-AK), and focused on fisheries science.

Ray Hilborn tells US Senate overfishing shouldn’t be most important concern

October 25, 2017 — WASHINGTON — A U.S. Senate subcommittee considering the reauthorization of the Magnuson-Stevens Act heard additional testimony Tuesday, with a University of Washington researcher telling lawmakers the U.S. is leaving money in the ocean.

Ray Hilborn, a professor at the university’s School of Aquatic and Fishery Sciences, noted that in many cases fisheries aren’t even bringing in half of the total allowable catch in some seasons. For example, in 2015, mixed bottom commercial fishermen caught USD 65 million (EUR 55.1 million) worth of fish available in the West Coast. The total allowable catch had an estimated value around USD 168 million (EUR 142.5 million).

Public Comment Guidelines

With the intent of developing policies in the Commission’s procedures for public participation that result in a fair opportunity for public input, the ISFMP Policy Board has approved the following guidelines for use at management board meetings:

For issues that are not on the agenda, management boards will continue to provide opportunity to the public to bring matters of concern to the board’s attention at the start of each board meeting. Board chairs will use a speaker sign-up list in deciding how to allocate the available time on the agenda (typically 10 minutes) to the number of people who want to speak.

For topics that are on the agenda, but have not gone out for public comment, board chairs will provide limited opportunity for comment, taking into account the time allotted on the agenda for the topic. Chairs will have flexibility in deciding how to allocate comment opportunities; this could include hearing one comment in favor and one in opposition until the chair is satisfied further comment will not provide additional insight to the board.

For agenda action items that have already gone out for public comment, it is the Policy Board’s intent to end the occasional practice of allowing extensive and lengthy public comments. Currently, board chairs have the discretion to decide what public comment to allow in these circumstances.

1. Comments received 3 weeks prior to the start of a meeting week will be included in the briefing materials.

3. Following the Tuesday, November 7, 2017 5:00 PMdeadline, the commenter will be responsible for distributing the information to the management board prior to the board meeting or providing enough copies for the management board consideration at the meeting (a minimum of 50 copies).

The submitted comments must clearly indicate the commenter’s expectation from the ASMFC staff regarding distribution. As with other public comment, it will be accepted via mail, fax, and email.

Big decision looms over little oily fish that feeds so many others

Fishery managers eye whether to weigh ecological role of Atlantic menhaden in setting harvest limits

October 12, 2017 — If you were to round up all of the menhaden swimming along the Atlantic coast and somehow put them on a scale, they’d weigh in at about 1.2 million metric tons.

To visualize that, imagine 220,000 Asian elephants stampeding along the coast — about five times more than exist in the world. For menhaden, though, that equates to tens of billions of tiny fish. This fall, fishery managers will tackle the question of whether that’s enough.

An update on the status of Atlantic menhaden released in August found the population robust. The current biomass, combining their number and weight, is the greatest that scientists have estimated in the last four years — and more than was seen anytime from 1992 through 2007.

Menhaden are not overfished, the report concluded — fewer than 200,000 metric tons were caught last year.

But critics, including some scientists and many conservation groups, say those figures only tell part of the story. Menhaden should not be looked at in isolation, they say, but as part of the broader marine ecosystem, where the small, oily fish is an important food for other fish, whales, sea birds and a host of other species.

“We’re probably not going to damage the menhaden stock all that much by continued heavy fishing. It seems to be in reasonably good shape,” said Ed Houde, a fisheries scientist with the University of Maryland Center for Environmental Science. “But what happens to the rest of the ecosystem? That’s the question mark.”

In November, the Atlantic States Marine Fisheries Commission, a panel of state fishery managers that regulates catches of migratory fish along the coast, will grapple with whether it should continue to manage menhaden as a single species — or begin considering its value to the ecosystem as well.

Fish shrinking as ocean temperatures rise

October 4, 2017 — One of the most economically important fish is shrinking in body weight, length and overall physical size as ocean temperatures rise, according to new research by LSU Boyd Professor R. Eugene Turner published today. The average body size of Menhaden—a small, silver fish—caught off the coasts from Maine to Texas—has shrunk by about 15 percent over the past 65 years.

Menhaden make up about one-half of the Atlantic and Gulf of Mexico fish harvest and had a dockside value of about $129 million in 2013. They are coastal species that spawn offshore and move to estuaries where juveniles grow to one- and two-year old fish. The air and sea surface temperature off the Atlantic coast and the Gulf of Mexico has steadily increased, especially in estuaries, where heat exchange occurs efficiently between air and sea. Adult menhaden return offshore where they are harvested with purse seine nets.

Little Fish, Big Worry: Future of Menhaden Sparks Concern

October 2, 2017 — PORTLAND, Maine — A big decision about the future of a little fish is attracting the attention of ocean conservation groups who say they are concerned about whether menhaden fishing can be considered sustainable.

Industry players are petitioning the London-based Marine Stewardship Council to offer its well-known sustainability certification to the Atlantic Ocean and Gulf of Mexico fisheries for menhaden, a small schooling fish that plays a vital role in the ocean food web.

The Marine Stewardship Council’s sustainability marker, prominently displayed on seafood packages in grocery stores, is one of the most recognized seafood labels in the marketplace. The company requesting the certification is Omega Protein, which is the largest harvester of menhaden in the Atlantic and the Gulf.

A sustainable certification for menhaden is important because companies that use menhaden products are starting to require it, said Ben Landry, a spokesman for the Houston-based company. He said it’s becoming especially common for aquaculture firms to require that feed be certified responsibly harvested.

Landry said the company is hopeful to obtain certification sometime in early 2018.

“It’s the gold standard in seafood certification. It signals to consumers that you’re truly a sustainable company that harvests these fish,” he said.
