Wasted Fish – What to Make of Recent Data Showing 10% of Fish are Discarded at Sea?

July 12, 2017 — A paper published last week titled, Global marine fisheries discards: A synthesis of reconstructed data, concludes that commercial fishermen have thrown away (discarded) about 10% of catch over the past decade. Researchers, led by Dirk Zeller, used catch reconstructions – estimates of how many fish were caught – to approximate that around 10 million tons of fish are discarded at sea per year. This number is down from a high of 18 million tons in the 1990s.

Zeller et al. 2017  suggest that the decline in discards are a result of declining fish stocks, though they acknowledge that gear and management improvements could also play a role. Indeed, worldwide fish stocks have remained relatively stable since 1990s, indicating that perhaps management and gear technology have played a larger role in reducing discards than researchers propose.

Previously, we have featured an in-depth analysis of discard policy in the EU by Philip Taylor & Griffin Carpenter.

In the below comments we offer 3 different perspectives on fishing discards and the recent Zeller et al. 2017 paper.

Comment by Bill Karp, Affiliate Professor, University of Washington

The recent paper by Zeller et al highlights challenges associated with estimation of discards and interpretation of overall estimates and trends. Their work builds on an extensive body of research, most notably earlier global discard estimates published in 1994 and 2005, and relies heavily on the Sea Around Us database and catch and discard estimation methods outlined by the authors.

Unwanted fish results from almost all fishing . Fishers generally target a species or group of but fishing gear is not perfectly selective for species or size. Regulations may preclude landing of some species and sizes (usually smaller fish), or economic factors may favor retention of larger fish or higher-value species  If the undesired fish are not retained and marketed in some form (e.g. as fish meal for aquaculture feed, or fertilizer) they are generally returned to the sea as discards. This issue is not unique to fishing, waste is a concern in all types of food production. In the United States, roughly 7% of all crops are wasted at the farm (i.e. never harvested), with estimates up to 40% of food waste through the supply chain.

In recent years, waste associated with fisheries discard has become a major public policy issue in some regions, with partial discard bans being implemented in Norway, the European Union, and elsewhere. At the same time, regulatory and operational innovations have resulted in lower discard rates in some fisheries, and demonstrated the potential for broader improvement. Fisheries discard can be reduced by development and use more selective fishing methods, developing markets for unfamiliar species or products, and by regulatory approaches which provide incentives for improved selectivity and/or utilization or even prohibit certain types of discarding.

Zeller et. al. argue that high-grading (discarding of lower-value in favor of higher-value fish) and regulatory discard are major problems and shortfalls of individual transferable quota (ITQ) fisheries. While high-grading and regulatory discarding are substantive causes of discarding, ITQ-type of programs (catch share, rights-based) may include provisions for transferring of quota among participants as well as sharing information that can improve selectivity. These types of programs also reduce or eliminate the race for fish and thereby reduce levels of unwanted fish. They can also encourage accountability, a key to improved catch and discard data. Examples can be found in Alaska and elsewhere.

EU Discard Ban Stimulates Innovation and Improved Cross-Sectoral Communication

July 7, 2017 — The following is a report written by Dr. Bill Karp, Affiliate Professor at University of Washington:

The Common Fisheries Policy (CFP) governs fisheries management in the European Union and is, very roughly equivalent to the Magnuson-Stevens Act in the US. The CFP is updated (reformed) every ten years. Article 15 of the 2013 reform is entitled “Landing Obligation” and includes the following text:

  1. All catches of species which are subject to catch limits and, in the Mediterranean, also catches of species which are subject to minimum sizes as defined in Annex III to Regulation (EC) No 1967/2006, caught during fishing activities in Union waters or by Union fishing vessels outside Union waters in waters not subject to third countries’ sovereignty or jurisdiction, in the fisheries and geographical areas listed below shall be brought and retained on board the fishing vessels, recorded, landed and counted against the quotas where applicable, except when used as live bait, in accordance with the following time-frames:

For further details (including exceptions) see http://eur-lex.europa.eu/legal-content/EN/TXT/PDF/?uri=CELEX:32013R1380&rid=1

This “Landing Obligation” or discard ban was enacted in response to public concerns regarding perceived wasteful practices. It is being implemented over several years, initially in the more industrialized, large scale fisheries of northern Europe. Many concerns about practicability, cost, and other aspects have been raised and hotly debated in Europe, but implementation is proceeding.

As expected, this change in public policy has directly impacted many aspects of fishing, handling, processing, and marketing. The EU has funded several projects designed to encourage cross-sectoral engagement to improve gear selectivity, share information on avoiding unwanted catch (spatial, areal, etc.), encourage advances in handling, stimulate marketing opportunities, etc. Among these initiatives is a project called “DiscardLess” which is a four-year, multi-million Euro project. Through this project, researchers and stakeholders from throughout Europe and elsewhere are working together to reduce discards in European fisheries. The DiscardLess Consortium includes 31 partners from 20 countries.

Participants include fishermen, gear technologists, economists, handling, processing and marketing experts, and marine scientists. Work packages within the project focus on selectivity, avoidance, optimal use, ecosystem considerations, and policy aspects. Work began more than two years ago, and some important results are already apparent. For example, the Atlas, and Selectivity Manual provide broad-based and comprehensive information, much of which will be useful to US fishermen.

DON CUDDY: A clean sweep on the ocean floor

October 4th, 2016 — Most of the reporting in the media about commercial fishing and declining stocks in the Northeast dwells on how dire the situation has become with the fault generally attributed to fishermen and “overfishing.”

The view on the waterfront is very different, however. Fishermen have long maintained that there is a huge disconnect between what they see on the water and the conclusions derived from the surveys and stock assessments made by the National Oceanaic and Atmospheric Administration. Their claims have been dismissed as self-serving. Now it seems the fishermen have a strong case. On a recent bottom trawl survey, a typical industry net caught four times as many flatfish as the rig used on the government trawl surveys.

For years, fishermen have clamored for more collaborative research using industry vessels. They were largely ignored. But in August, Dr. Bill Karp, director of the Northeast Fisheries Science Center in Woods Hole, revealed a plan for NOAA Fisheries to shift all or part of its trawl surveys from its research vessel, the Henry B. Bigelow, to commercial fishing boats. At the same time, from Aug. 7-21 the Point Judith fishing vessel Karen Elizabeth was at sea conducting a twin-trawl survey on behalf of the Science Center with a team of scientists working alongside the crew.

The boat was rigged to tow two nets simultaneously, each of the type used on the Bigelow, with one significant difference. One net was fitted with a rockhopper and the other had a chain sweep. Because different fish species behave differently, fishermen use a chain sweep, attached to the leading edge of the net and in contact with the sea floor, when targeting flatfish such as witch flounder. These fish hide in the sediment on soft bottom to evade predators. You will hear fishermen refer to fishing boats with rockhoppers as “hard bottom boats” because those boats typically go after other species such as cod and haddock which tend to be found over rocky or gravel bottom.

The Bigelow uses a rockhopper on every tow, despite surveying in our multispecies fishery. That is because this gear allows nets to be towed across a variety of habitats. A net equipped with a chain sweep is prone to snag on a rocky bottom. Its exclusive use of a rockhopper has been a point of contention with the fishermen since the Bigelow commenced operations in these waters. Fishermen openly questioned its accuracy in estimating flatfish abundance. The survey work on the Karen Elizabeth has provided the evidence that their skepticism is well founded. Here are some relevant quotes taken from the Science Center’s own paper, authored by the scientists who were on the Karen Elizabeth to conduct the study:

“On average, catch rates in the experimental chain sweep gear were about 4-fold the catch rates of the rockhopper sweep gear used on the standard survey.”

Bottom trawlers sought for NOAA surveys

September 2, 2016 — NOAA Fisheries is looking for a few good boats.

The federal fishing regulator’s Northeast Fisheries Science Center in Woods Hole seeks one to three commercial fishing boats to participate in the agency’s bottom trawl survey in the waters of the mid-Atlantic and New England regions of the Atlantic Ocean.

The use of the commercial vessels to help supplement — or in some cases, supplant — the work of the National Oceanic and Atmospheric Administration’s survey vessel, the FSV Henry B. Bigelow, is one of the first steps in NOAA’s recently announced plan to incorporate more commercial boats in the trawl survey.

NOAA announced on Aug. 3 that it plans to shift “part or all” of its spring and fall trawl surveys to fishing industry boats over the next five years in an attempt to get more consistent and expansive coverage and to bridge the current gap between what fishermen say they are seeing on the water and what NOAA is reporting from its trawl surveys.

“The goal is to build trust in the best science through cooperative and collaborative research and improving both the communication and transparency with the fishing industry,” Bill Karp, the director of the Northeast Fisheries Science Center, said at the announcement.

Sharing survey work signals positive shift in government, fishermen relationship

August 9, 2016 — The announcement from NOAA on Tuesday that they will begin to transition the Northeast Fisheries Science Center’s bottom trawl surveys from their research ship, the Henry B. Bigelow, to fishing industry vessels is a cause for celebration on the waterfront and represents a real opportunity to get the fishing industry in New England out of disaster mode. It is a bold decision but it is undoubtedly the correct one and, from an industry perspective, one that is long overdue.

Science Center director Dr. Bill Karp deserves enormous credit for setting this process in motion. It is a clear signal that NOAA wants to build trust and transparency, qualities that have not always been in evidence in its long and difficult relationship with the commercial fishing industry in New England.

The problems facing our fisheries are well documented. But amidst all the controversy, litigation and hard feelings surrounding fishery management, there is general agreement on one point: the need for better fishery science, to enable timelier, more accurate and more useful stock assessments. Maintaining healthy, sustainable fish stocks to support a robust commercial fishing industry are goals shared by all. Of course fishermen should be actively involved in the collection of survey data since the results determine how much fish they are permitted to catch.

We hear a great deal in the media about overfishing but the value of groundfish landings has declined by almost 50 percent since 2011. Yet the catch for several of our stocks is less than 50 percent of the quota because of regulatory constraints and catch limits that do not reflect what fishermen see out on the water. It is a fact that more fish are dying of old age in our waters than are coming ashore, largely as a result of scientific uncertainty. Fishermen continue to pay a heavy price for such uncertainty and many understandably feel as though they have become merely objects of regulation.

‘Sea change:’ NOAA to shift fish surveys to commercial boats

August 3, 2016 — In what one advocate called “a potential sea change” for the commercial fishing industry, NOAA Fisheries announced intentions Tuesday to shift all or part of long-controversial stock surveys from its Bigelow research vessel to commercial boats, saying a transition over the next five years could bring “greater shared confidence” in survey results.

“We have to learn to work better with the (commercial fishing) industry — we have to open up better lines of communication,” Dr. Bill Karp, director of NOAA’s Northeast Fisheries Science Center in Woods Hole, said of the transition.

How fish stocks are measured has been one of the biggest points of contention for years between governmental regulators and commercial fishermen, as survey results affect seasonal catch limits, quotas for various species and more. The latest questions about NOAA’s Henry R. Bigelow research ship arose this spring, for example, when maintenance problems delayed NOAA’s spring survey from April to June.

Don Cuddy, program director for the Center for Sustainable Fisheries in New Bedford, said fishermen also have felt the Bigelow is unable to accurately count “flatfish,” such as yellowtail flounder, because of the type of gear it tows.

“Yellowtail flounder are critical to the scallop industry as well as the groundfish,” Cuddy said, explaining that low quotas for yellowtail can force scallopers to prematurely stop operations, if they incidentally snag too many yellowtail as a bycatch.

Cuddy said enabling commercial boats to participate in NOAA surveys — and placing government scientists on the same boats as fishermen — could help “close the credibility gap” that has long surrounded survey results.

NOAA Fisheries Considers Moving Trawl Surveys to Fishing Vessels

August 2, 2016 — The following was released by NOAA:

NOAA Fisheries is initiating a planning process to support its intention to transition part or all of the Northeast Fisheries Science Center’s spring and fall bottom trawl surveys from the NOAA Ship Henry B. Bigelow to fishing industry vessels provided that survey data collection quality and time series integrity can be maintained.

“The bottom trawl survey is perhaps the most valuable ecological data set that we maintain at the Center,” said Bill Karp, the center’s director. “Those data are critical for many of the fishery stock assessments in the region and are mined by a wide variety of researchers for other purposes. By sharing the responsibility for gathering these data with the fishing industry, I think there will also come greater shared confidence in the results obtained using them.”

A typical survey covers about 400 stations off the Northeastern U.S. in the Gulf of Maine, On Georges Bank and south to Cape Hatteras. The scientific trawl is towed to collect marine species, while a variety of environmental and oceanographic data are also being collected. Biological samples are taken from trawled animals for a variety of studies and to calculate an index of catch per tow by species. The resulting data are used to study everything from food habits to habitat use and the effects of climate change.

Transitioning such a large-scale data gathering enterprise to commercial vessels is a complex challenge, but Karp notes it has been done in the past, both when it needed to move from one research vessel to another and elsewhere in the world where commercial fishing vessels are used for this purpose. “It’s important to note, “said Karp, “that this will happen providing we can also maintain survey data collection and time series integrity.”

The target timeframe for the transition is five years. A science center working group is being established to develop options and criteria for making the shift. They will work closely with industry during this process through the Northeast Trawl Survey Advisory Panel, convened jointly by the Mid-Atlantic Fishery Management Council, the New England Fishery Management Council, and the Atlantic States Marine Fisheries Commission.

The NEFSC bottom trawl survey is the longest-running of its kind in the world. The first trip was in May 1963, and since then seasonal surveys have been conducted annually. The surveys are conducted from government research vessels operated by NOAA and her predecessor agencies.

NOAA Fisheries Releases Draft Northeast Climate Science Action Plan

June 22, 2016 — The following was released by NOAA:

NOAA Fisheries is seeking comments on a draft plan to help guide our approach to increase the production, delivery, and use of climate-related information and to reduce impacts and increase resilience of fish stocks, fishing-dependent communities, and protected species. As part of its efforts to increase the production, delivery, and use of climate-related information, NOAA Fisheries has released a draft climate science action plan for the U.S. Northeast. It outlines a strategy and specific actions for increasing understanding of, preparing for, and responding to climate change effects on the region’s ocean species — including marine and anadromous fish, invertebrates, marine mammals, sea turtles and seabirds — and the people that depend on them.

The draft action plan was developed to meet the growing demand for information to better prepare for and respond to climate-related impacts. Ultimately, this information will be used to develop science-based strategies to sustain our marine resources and human communities that depend on them during this time of changing climate. Each NOAA Fisheries’ region will have a climate science action plan that helps implement the NOAA Fisheries Climate Science Strategy.

“Our science center is studying how climate variability is affecting fishery species and marine communities in the region,” said Bill Karp, Director of NOAA’s Northeast Fisheries Science Center. “Warming oceans, rising seas, and ocean acidification are affecting marine life and also disrupting fisheries and local economies. We hope this plan will help us provide the kind of information needed to support actions that will ensure sustainable fisheries and coastal communities in this time of great change.”

The Northeast region includes waters that extend from Cape Hatteras, North Carolina to the western end of the Scotian Shelf, the Mid-Atlantic Bight, Southern New England, Georges Bank, and the Gulf of Maine. These waters are among the fastest warming in the world’s oceans, a result of both human-caused climate change and natural climate variability. Fish, shellfish, marine mammal, and sea turtle populations are already responding to this changing environment, which is also affecting habitats that these species use, predator-prey relationships, and competition in the ecosystem. Human communities that depend on the function and health of this ecosystem are also feeling the effects.

“With water in the Gulf of Maine warming at a significant pace, understanding how environmental changes are affecting our species is critical to planning for a sustainable fisheries future,” said John Bullard, regional administrator for NOAA Fisheries Greater Atlantic Region. NOAA Fisheries’ Northeast Fisheries Science Center collects, analyzes and provides scientific information necessary to fulfill the agency’s mission to sustain marine species in watersheds, estuaries and the coastal ocean. The NOAA Fisheries Greater Atlantic Regional Office ensures effective science-based management of these resources to achieve the same goals. The Northeast Regional Climate Action Plan focuses on present climate variability and future climate change in this large marine ecosystem.

“This plan builds on the work already underway in the region to address climate change,” said Jon Hare, of NOAA’s Northeast Fisheries Science Center and lead author of the plan. “For instance, we’ve been leaders in long-term monitoring needed to explain change, linking stock assessment and climate models, and working toward an ecosystem-based understanding of sub-regions like Georges Bank. We are also providing biannual and annual state-of-the-ecosystem reports to federal fishery managers to support their efforts to implement fishery management in a more holistic way, accounting for ecosystem factors as well as the biology of the fish.”

The core elements of the Northeast Regional Action Plan include developing new multispecies models that incorporate environmental terms such as temperature and ocean acidification, conducting work to better understand how climate change is forcing change in species distribution and habitat use, initiating a Northeast Climate Science Strategy Steering Group, cooperative research with the fishing industry, and integrating social science into ecosystem assessments in order to better account for human dimensions.

Designed to increase the production, delivery, and use of climate-related information, the plan will guide efforts to provide timely information to managers to reduce impacts and increase resilience of fisheries, protected species and coastal communities.

If you have questions about the plan, please contact jon.hare@noaa.gov. Written comments can be submitted via email to nmfs.gar.nerap@noaa.gov by July 29, 2016.

NOAA Eyes Possible Move from Woods Hole

May 27, 2016 — The National Oceanic and Atmospheric Administration (NOAA) is zeroing in on a new home for its Northeast Fisheries Science Center, a mainstay in the culture and economy of Woods Hole. The federal agency said last week that it has narrowed its search to Barnstable County, which includes all of the Cape, and would keep the center closer to research partners in the area.

NOAA began assessing its Woods Hole complex more than a year ago, in light of dwindling office and laboratory space and other concerns. As a first step, a feasibility study is expected to be completed this summer or fall, although a final decision about whether and where to relocate is likely years down the road.

But NOAA representative Teri Frady told the Gazette that the process is moving forward.

“The analysis thus far has reviewed many locations across the region and based on needs and partnerships, Barnstable County has been selected as the best fit for a potential facility re-capitalization,” she said in an email.

The original list had included New Bedford, Narragansett, R.I., and Groton, Conn. In recent months since the plans emerged, officials in New Bedford and elsewhere have lobbied for NOAA to come to their towns, while the Falmouth selectmen have pleaded for the science center to stay put.

But it may not be as simple as picking up and leaving, said Bill Karp, the center’s director of science and research.

“There are a number of different options on the table,” Mr. Karp told the Gazette. “One possibility is that we would maintain some presence on the waterfront in Woods Hole, and then have a second facility upland. But there is a lot of moving parts to this.”

Saving Seafood Executive Director Talks Lost NOAA HabCam

 

WASHINGTON (Saving Seafood) – May 25, 2016 — A $450,000 camera used to survey scallops on the ocean floor was lost Friday when a NOAA-chartered vessel towed it too close to a known ship wreck, as reported yesterday by the New Bedford Standard-Times.

This morning, Saving Seafood Executive Director Bob Vanasse spoke with New Bedford 1420 WBSM morning host Phil Paleologos about the accident, saying it proves the need for changes to the Atlantic scallop survey.

“The Fisheries Survival Fund [which represents members of the Atlantic scallop fleet] has been arguing for some time that the Federal scallop survey should not be done just by one single piece of equipment on one single vessel, but that there should be backups,” Mr. Vanasse said.

Compounding the problem the lost camera will have on this year’s Federal scallop survey is the fact that respected scientist Kevin Stokesbury, from UMass Dartmouth’s School for Marine Science and Technology, did not receive government funding for his own survey. Dr. Stokesbury’s surveys, which use cameras dropped into the ocean to take pictures of the seafloor, had previously been funded every year since 1999.

Mr. Vanasse called the loss of NOAA’s HabCam habitat camera last week “a combination of really bad circumstances.” He raised concerns about researchers aboard the R/V Hugh R. Sharp piloting the expensive HabCam so close to the well-known and charted wreckage of the Bow Mariner, where a cable apparently snagged the sunken ship and detached the camera. He also pointed out that many industry leaders raised concerns that a volunteer worker was piloting the HabCam at the time of the accident.

NOAA researchers are beginning efforts to find the HabCam today, nearly a week after it was lost, and say they will be able to make up for lost time. But scallop industry experts are unconvinced, according to Mr. Vanasse.

“That doesn’t really make sense,” Mr. Vanasse said of the industry perspective. “If they plan to go out for a certain time, they do that because they need it.”

The timing issue is further complicated because NOAA leases the Sharp from the University of Delaware for a limited period of time at high expense. Even if NOAA is able to salvage the HabCam, it will likely take more than a week of valuable time, Mr. Vanasse said.

The lost HabCam is not the first issue NOAA has had a with a research vessel in recent weeks. Earlier this month the R/V Henry B. Bigelow, the ship that surveys for groundfish and many other species on the East Coast, was delayed due to mechanical issues with its generators. The Bigelow was already running more than a month behind before its generator problems. Mr. Vanasse pointed out that Dr. Bill Karp, director of the Northeast Fisheries Science Center, has been pushing for NOAA to charter commercial fishing boats as backups, including at April’s NEFMC meeting (skip to 31:51 to listen to Dr. Karp).

“We need higher ups at NOAA to listen to what Dr. Karp has been saying about needing backups on the groundfish survey,” Mr. Vanasse said. “And we need everybody at NOAA to pay attention to what the [Fisheries] Survival Fund has been saying about having backups on the scallop survey.”
