ASMFC Begins Preparations for American Lobster Benchmark Stock Assessment

January 30, 2018 — ARLINGTON, Va. — The following was released by the Atlantic States Marine Fisheries Commission:

The Atlantic States Marine Fisheries Commission has initiated a benchmark stock assessment for American lobster (Homarus americanus) to be completed in the summer of 2020. The goals of the assessment are to evaluate the health of stocks along the U.S. Atlantic coast and inform management of this species. The Commission’s stock assessment process and meetings are open to the public, with the exception of discussions of confidential data, when the public will be asked to leave the room.

The Commission welcomes the submission of data sources that will contribute to the goals of the assessment. This includes, but is not limited to, data on abundance (young-of-the-year, recruits, full recruits), biological samples (sex, maturity, weight, carapace length), life history information (growth, natural mortality, mating, shell disease), stock connectivity (tagging data), catch (harvest, fishing effort) and information regarding the environmental influence on lobster life history. For data sets to be considered, the data must be sent in the required format, with accompanying description of methods, to the Commission by April 13, 2018.

The Data Workshop will be conducted May 14-17, 2018 at the University of Rhode Island’s Graduate School of Oceanography, 218 South Ferry Road, Narragansett, RI 02874. This workshop will review available data sources for American lobster and identify datasets to be incorporated in the stock assessment.

For those interested in submitting data and/or attending the American Lobster Data Workshop (space is limited), please contact Jeff Kipp, Senior Stock Assessment Scientist, at jkipp@asmfc.org or 703.842.0740.

Healthy status of Atlantic menhaden confirmed

August 10, 2017 — The Atlantic States Marine Fisheries Commission (ASMFC) on August 2 received an updated stock assessment that shows Atlantic menhaden is neither overfished nor experiencing overfishing. These positive conclusions mirror the results of the ASMFC’s 2015 benchmark assessment of Atlantic menhaden, which showed a healthy and sustainable stock, as reported by the Menhaden Fisheries Coalition.

Atlantic Menhaden Stock Assessment Update Finds Resource Not Overfished and Overfishing Not Occurring

August 3, 2017 — ALEXANDRIA, Va. — The following was released by the Atlantic States Marine Fisheries Commission:

The Atlantic States Marine Fisheries Commission’s Atlantic Menhaden Management Board reviewed the results of the 2017 Atlantic Menhaden Stock Assessment Update, which indicates the resource remains healthy; it is not overfished nor experiencing overfishing relative to the current biological reference points. In 2016, population fecundity, a measure of reproductive capacity, is estimated to be 83,486 billion eggs which is well above the threshold (57,295 billion eggs) but below the target (99,467 billion eggs). Additionally, total fishing mortality is estimated to be 0.51, below both the fishing mortality threshold (1.85) and target (0.80). The stock assessment update uses the same modeling approach as the 2015 Atlantic Menhaden Benchmark Stock Assessment but added additional years of data from 2014-2016.

While the stock status was assessed in the same way as the 2015 benchmark report, the reference point values have changed. Adding additional years of data to the model resulted in generally higher fishing mortality values throughout the times series which changed the scale of the reference points. While the scale is different and the trend differs in some years, the stock status for both fishing mortality rate and fecundity has been similar over the past decade.

Atlantic menhaden is harvested by both commercial reduction and bait fisheries. In 2013, Amendment 2 to the Fishery Management Plan implemented a total allowable catch (TAC) of 170,800 metric tons (mt). The coastwide TAC was increased by 10% to 187,880 mt for the 2015-2016 fishing years and by another 6.45% to 200,000 mt for the 2017 fishing year. In 2016, reduction landings were 137,400 mt and accounted for approximately 76% of coastwide landings and bait landings were 43,100 mt and comprised 24% of coastwide landings.

Update Assessment Confirms Sustainable Atlantic Menhaden Stock

Atlantic fisheries managers will take positive findings into consideration for management purposes

ALEXANDRIA, Va. – August 2, 2017 – The following was released by the Menhaden Fisheries Coalition:

Today, the Atlantic States Marine Fisheries Commission (ASMFC) was presented with an updated stock assessment that shows Atlantic menhaden is neither overfished nor experiencing overfishing. These positive conclusions mirror the results of the ASMFC’s 2015 benchmark assessment of Atlantic menhaden, which showed a healthy and sustainable stock.

The 2017 Atlantic Menhaden Stock Assessment Update, prepared by the ASMFC’s Atlantic Menhaden Stock Assessment Subcommittee using data through the 2016 fishing year, shows that fishing mortality remains well below the ASMFC’s target levels (see Table 7.2.1.1 below). The assessment further indicates that the target has not been exceeded for many years; this includes 2012, when the ASMFC cut Atlantic menhaden catch rates by 20 percent based on a flawed stock assessment.

“We’ve maintained for years that Atlantic menhaden is being managed sustainably, and today’s update assessment continues to prove our case,” said Peter Himchak, Senior Fisheries Scientist at Omega Protein, a member of the Menhaden Fisheries Coalition. “Coalition members who make their living in the menhaden fishery have worked diligently to safeguard this resource, and today’s findings validate their hard work.”

The Assessment Update approved today also shows an increase in Atlantic menhaden biomass and numbers of individual fish (see Figure 6.2.3.4 below). Taken in combination, positive trends for both biomass and numbers of individual menhaden are strong indications of a healthy menhaden stock.

In 2012, the ASMFC slashed Atlantic menhaden catch rates after a flawed stock assessment indicated menhaden was being overfished. However, a 2015 assessment using improved methods and better science showed that menhaden had not been overfished in 2012 or at any time since the 1960s, and that the stock was healthy. Based on these positive results, the ASMFC raised the catch quota for Atlantic menhaden in both 2015 and 2016, but catch rates remain below 2012 levels when quota reductions were implemented.

“This update assessment further confirms our view that the 2012 harvest cuts were unwarranted and not based on sound science,” said Jeff Kaelin, Government Relations Coordinator at Lund’s Fisheries, another Coalition member. “In large part due to those cuts, we are underfishing this resource and unnecessarily hurting the fishermen who depend on it. The ASMFC’s menhaden board has options before it that could restore the fishery to pre-2012 levels, and we ask that they give those options the consideration they deserve.”

KENNY HEBERT: CCA is telling fish tales about Omega Protein

April 20, 2016 — On April 2, the Sun Herald published an op-ed from the spokesman of the Coastal Conservation Association — Mississippi, F.J. Eicke (“A most important fish raises need for public scrutiny”), that was filled with more holes than a fisherman’s net. Sadly, time and time again, Mr. Eicke has demonstrated dismissiveness toward sustainable fisheries and the hardworking men and women of Mississippi’s commercial fishing industry.

A major contention offered by Mr. Eicke is that Mississippi’s resident menhaden stock is troubled. This statement is 100 percent incorrect and is little more than a scare tactic. There is no such thing as “Mississippi menhaden.” Due to their very nature — their biology and habitat — menhaden are a Coastwide migratory species, which is why menhaden stock assessments are conducted on a Coastwide basis.

As such, Mr. Eicke’s claim that the public “has no basis for assessing the catch in Mississippi waters” is nonsensical. Menhaden cross state borders routinely as they move around the Gulf. To assess the amount of menhaden in Mississippi waters at any given time is pointless, since, due to migratory patterns, the stock size would be completely different in subsequent days, weeks or months.

Contrary to Mr. Eicke’s claim that menhaden regulations are “minimal,” existing management has been successful in maintaining a sustainable fishery. According to the most recent, peer-reviewed Gulf States Marine Fisheries Commission stock assessment, the menhaden stock is healthy: It is neither overfished nor experiencing overfishing. The same results have been consistent going back 20 years.

West Coast Catch Share Program Failure Keeps Vessel Off Fishing Grounds for 2016 Season

SEAFOOD.COM NEWS [SeafoodNews] By Susan Chambers – March 21, 2016 — Criticism that the West Coast catch shares program is underperforming came to the forefront recently at the Pacific Fishery Management Council meeting in Sacramento.

West Coast trawlers have been operating in fear of a “disaster tow” or “lightning strike” of a choke species since the beginning of the individual quota program in 2011. And for the F/V Seeker, a disaster tow of 47,000 pounds of canary rockfish – a species at the time listed as overfished — in November 2015 will prevent it from fishing for all of 2016.

The Seeker’s misfortune is an extreme example of the program’s failure, particularly for those fishing in the non-whiting sector.

Jeff Lackey, who manages the vessel, testified to the PFMC the vessel is in a bind and already has made plans to fish in Alaska for most of 2016 and return to fishing off the West Coast in 2017. The Seeker fishes in both the non-whiting shoreside sector and in the whiting mothership sector.

The Seeker is a victim of several features of the current regulatory system in the West Coast individual quota program.

First, current vessel limits prohibit the Seeker from acquiring enough quota to solve its deficit.

Second, canary rockfish was listed as overfished for more than a decade but an assessment accepted by the council in 2015 shows canary rockfish has been rebuilt.

And third, the PFMC’s management process operates on a two-year cycle, with no way to change annual catch limits (ACLs) mid-cycle.

“[The F/V Seeker] is not the only one,” Pete Leipzig, director of the Fishermen’s Marketing Association, told the Council. Other trawlers have come up against vessel limits for other species that have prevented them from fishing for some time, but none have been confronted with the extremity of the Seeker’s situation.

The vessel limits were designed to prevent consolidation of the fleet. Bycatch of choke species have prevented many vessels from capturing target fish. Fear of a disaster tow — one so extreme that a quota pound deficit cannot be covered in the existing fishing year — has limited trading of quota as fishermen hoard these species to cover their fishing operations for the year.

The biennial management cycle only complicates matters. Several years ago, the PFMC instituted two-year management cycles to streamline the management and regulations process, with stock assessments being conducted in off-year cycles. For instance, the council and the National Marine Fisheries Service set annual catch limits for 2015 and 2016 at the same time. Stock assessments are done and presented to the council for acceptance in odd years.

The council accepted the canary rockfish assessment in 2015. ACLs could double for the species were it not for the two-year management cycle.

There is no mechanism to allow the council or NMFS to increase the 2016 annual catch limits for canary in 2016. If higher ACLs would have been allowed this year, the Seeker’s deficit could have been covered and it would be fishing this year.

The Seeker is a member of the Newport, OR based Midwater Trawlers Cooperative. The organization proposed a solution to the Seeker’s problem: use an alternative compliance option that was eliminated during the development of the catch shares program. It would have been available for overly restrictive events, such as the Seeker’s, but still hold fishermen accountable. The council opted not to move forward with examining that option at this time.

This is the new reality of the West Coast individual quota program: rebuilding species will be encountered more frequently and fishermen could be held to conservative annual catch limits for a year or more if they experience an infrequent disaster tow and have insufficient quota to cover their deficit.

“As the regulations are currently written, any vessel that experiences the same situation would likely have to sit out of the shoreside trawl program for several years … This seems overly punitive and raises equity concerns,” Heather Mann, executive director of the MTC, wrote in a public comment letter to the council.

Although the Council took no action to try to remedy the situation in March, the issue is sure to come up again as the Council begins the five-year program review in June.

Between 2011 and 2015, the non-whiting shoreside quota program has harvested only between 20 and 35 percent of its annual quota. The industry has identified several dozen changes it would like to see implemented in an effort to make the program work.
