Saving Seafood

Brexit Leaves French Fishermen On The Hook

September 12, 2017 — France’s busiest port, Boulougne-sur-Mer, sits just across the English Channel from Britain, in the Calais region.

Seagulls glide above scores of brightly painted boats docking to unload the catch of the day — mainly sole but also cod, roussette, crab and scallops.

It’s all sold at a bustling seaside market where Marie-Laure Fontaine sells seafood from a fishing boat called Providence.

“Sole and cod and turbot, we get these all from British waters,” Fontaine says. “And this is a worry.”

Up to 80 percent of fish caught by fishermen here comes from British waters, which are about a two-hour boat ride away.

French fishermen have been nervous since Britain voted to leave the European Union last year. That’s because when the divorce is final, the U.K. will also leave what’s called the Common Fisheries Policy.

“After that, the U.K. will be an independent coastal state, like Norway or the Faroe Islands or Iceland,” says Barrie Deas, chief executive of the U.K.’s National Federation Fishermen’s Organisations. “The U.K. will determine its own fishing quotas and access arrangements. So I think it’s realistic for the French to be worried.”

Something fishy in the quotas?

September 8, 2017 — There hasn’t been a large enough quota for fishermen to intentionally catch cod for four years, said Vito Giacalone, policy director for the Gloucester-based Northeast Seafood Coalition, which contends the federal limits on groundfish such as cod and flounder contradict what commercial fishermen are finding. The coalition has launched an effort to have input into the research done by the federal government as it sets the regulations.

“We’ve been seeing it for the past two decades, but more so in the past seven or eight years, especially on the [flounder and cod],” Giacalone said. “What we’ve seen in the last seven or eight years is that you can catch any fish you want at any time. That’s how available it is. So, we’re certain that the government estimates are wrong.”

Giacalone noted that scientists have a huge area to cover, and variables such as fish behavior — sometimes swimming near the top, sometimes the bottom, or abandoning certain geographic areas that are still included in the surveys — can influence the results.

The management plans are written by the New England Fishery Management Council in Newburyport, with input from several sources, including stock assessments from the National Oceanic and Atmospheric Administration’s Northeast Fisheries Science Center in Woods Hole. The assessments include surveys and catch and discard numbers from the commercial fishing industry, said Teri Frady, spokeswoman for the center.

The Northeast Seafood Coalition wants to play a bigger role by providing more information from the field. To do so, it is fund-raising to hire independent scientists to develop a method of collecting information that could be shared with government officials to develop more accurate assessments of species numbers.

“What [the regulators] should be doing is using the industry’s data to come up with a relative abundance index,” Giacalone said. “We realize it’s difficult because it has to be standardized, [and] it has to be unbiased. But until they admit that they could be getting it wrong, by a lot, they’re never going to put that work in. What the coalition is trying to do is shine a light on that.”

Frady said the NOAA center in Woods Hole is interested in any input.

Demand for groundfish data continues to increase

September 6, 2017 — The Sentinel Survey, now in its eighth year of research, collects data on the status of groundfish populations in Eastern Maine. The survey is conducted by Maine Center for Coastal Fisheries, in collaboration with the University of Maine. Fishermen visit a total of 84 survey stations from June to October, along with researchers who study the population, distribution, and most important, the genetic makeup of groundfish in each location, according to a news release from MCCF.

The Sentinel Survey has become the leading source of information on groundfish in Eastern Maine, the release states. The unique summer sampling season and localized-scale produces heavily sought after data. The survey design also uses a combination of gear types, longline and jig hooks, to sample areas where larger, more traditional trawling methods struggle—areas with rocky bottoms and an abundance of lobster traps. Since 2010, Maine Center for Coastal Fisheries has collected data on more than 20 groundfish species, most notably cod, halibut, mackerel, cusk, haddock, pollock and hake.

Increasingly, scientists are requesting access to survey samples of stomach content, heart, otolith (or ear bone), fin clip, gonad, and muscle tissue, as they seek to understand the status of depleted groundfish populations. According to lead researcher on the Sentinel Survey, Mattie Rodrigue, “data from even a single fish is crucial. Biological analysis can unlock a picture of where that species has been, the distinct sub-populations it’s related to, what it’s been eating, its reproductive patterns, and more.”

Maine Center for Coastal Fisheries has led a collaborative effort to distribute Sentinel Survey data to organizations up and down the coast, from Massachusetts to Canada. Scientists want access to specific data, and the survey can provide that information. Institutions, including the University of Maine, the University of New Hampshire, Gulf of Maine Research Institute, Woods Hole Oceanographic Institute, the Massachusetts Division of Marine Fisheries, and Fisheries and Oceans Canada, rely on the survey.

Maine center to study impact of climate change on cod, sole

September 6, 2017 — PORTLAND, Maine (AP) — The federal government is giving a Maine science center more than $1 million to investigate the impacts of climate change on important commercial fish species such as cod and sole.

Gulf of Maine Research Institute says it’s getting $1.1 million from the National Oceanic and Atmospheric Administration. The Portland-based center says researchers will also try to learn more about how fisheries management can be improved in the era of climate change.

Climate Change May Shrink the World’s Fish

A new study suggests warming sea temperatures could result in smaller fish sizes.

August 22, 2017 — Warming temperatures and loss of oxygen in the sea will shrink hundreds of fish species—from tunas and groupers to salmon, thresher sharks, haddock and cod—even more than previously thought, a new study concludes.

Because warmer seas speed up their metabolisms, fish, squid and other water-breathing creatures will need to draw more oxygen from the ocean. At the same time, warming seas are already reducing the availability of oxygen in many parts of the sea.

A pair of University of British Columbia scientists argue that since the bodies of fish grow faster than their gills, these animals eventually will reach a point where they can’t get enough oxygen to sustain normal growth.

“What we found was that the body size of fish decreases by 20 to 30 percent for every 1 degree Celsius increase in water temperature,” says author William Cheung, director of science for the university’s Nippon Foundation—Nereus Program.

These changes, the scientists say, will have a profound impact on many marine food webs, upending predator-prey relationships in ways that are hard to predict.

“Lab experiments have shown that it’s always the large species that will become stressed first,” says lead author Daniel Pauly, a professor at the university’s Institute for the Ocean and Fisheries, and principal investigator for the Sea Around Us. “Small species have an advantage, respiration-wise.”

Still, while many scientists applaud the discovery, not all agree that Pauly’s and Cheung’s work supports their dramatic findings. The study was published today in the journal Global Change Biology.

NOAA Endorses Eating Small Haddock — But What About Cod?

August 17, 2017 — SEAFOOD NEWS — The National Oceanic and Atmospheric Administration (NOAA) are giving their stamp of approval to eat small haddock.

In the July issue of the NOAA Fisheries Navigator, the government agency reports that smaller haddock does not necessarily mean an unhealthy stock. Looking at stats dating back to 1995, the size of the fish has been decreasing — but the population has been growing.

This trend is something that the organization has seen in the past. “A decline in the average size of Georges Bank haddock also happened in the mid-1960s when a larger number of haddock were born in 1963 and grew into the population,” the report reads. And according to their research, the size of the stock is large simply because the fish are “generally able to spawn before being harvested.” Data collected from Georges Bank haddock in 2015 revealed that 90% of the fish mature at age three. Commercial minimum size is 16 inches, which is generally a two to five year old fish. That means that most fish are able to spawn once or twice before being caught.

But the endorsement from NOAA still comes as a surprise to some. As Navigator magazine editor Kerry Hann notes in the September 2017 issue, the thumbs up to eat small haddock is a “somewhat peculiar statement from the U.S.-based organization tasked with providing science-based conservation and management for sustainable fisheries and aquaculture, marine mammals, endangered species and their habitats.”

For Hann, it all goes back to 1992 when the cod industry was faced with a similar situation.

“Fewer larger, spawning-aged fish were being caught, leaving the dwindling cod populations made up of primarily small, juvenile fish,” Hann writes. “Many at the time concluded that a healthy cod population could not be made up of only small fish.”

So, what about cod today? That’s an upcoming discussion for “Cod — Building the Fishery of the Future,” a conference being held by the Canadian Centre for Fisheries Innovation in November.

Electrofishing: Saviour of the sea or fracking of the oceans?

August 17, 2017 — The Netherlands is testing a new technique to fish – using electric currents. Electrofishing is controversial and is banned by the EU, but can be used on an experimental basis. Critics argue it is cruel because it breaks the backs of some larger cod. But advocates say it is less damaging for the environment than traditional beam trawling. James Clayton reports for BBC Newsnight.

Scientists to Meet Fishers of Cod, Sole About Future of Fish

PORTLAND, Maine (AP) — Fishery regulators are meeting with commercial and recreational fishermen around New England and New York to talk about upcoming assessments of key fish stocks.

The Northeast Fisheries Science Center has scheduled the “port outreach meetings” to talk about the assessments of 20 groundfish stocks. Groundfish are commercially significant fish species such as cod, haddock and sole that live near the ocean floor.

Charter boat owners see jump in cancellations as cod ban takes effect

August 14, 2017 — A new rule that recreational anglers in the Gulf of Maine can’t keep cod they catch is putting the squeeze on the charter boat industry, business owners say.

Capt. Don Taylor runs a six-person charter boat out of Rye Harbor. He said he can see the scientific reasoning behind imposing the restriction, but says it is causing people to cancel their reservations — even though they can still keep haddock, cusk and hake.

“I don’t think not allowing us to have one cod per person on a boat is going to make any difference at all. That’s my opinion on it,” Taylor said. “I think they’re going a little overboard, myself, and it’s hurting the charter boat industry.”

Allison Ferreira, who is in charge of communications for the Greater Atlantic Regional Fisheries Office in Gloucester, Mass., said the reason for the restriction is that recreational fishermen exceeded their cod catch limit by 92 percent last year.

Federal officials from the National Oceanic and Atmospheric Administration use estimates from the Marine Recreational Information Program to determine if a population is being overfished. In addition to getting reports from charter boat captains, they survey individuals who go out on their own boats.

Using Fishermen’s Ecological Knowledge to map Atlantic cod spawning grounds on Georges Bank

August 11, 2017 — The following abstract is from a research paper on Atlantic cod spawning grounds on Georges Bank. It was written by Gregory R. DeCelles, David Martins, Douglas R. Zemeckis, and Steven X. Cadrin, all from the University of Massachusetts Dartmouth School for Marine Science and Technology in New Bedford, Massachusetts. It was published in the July-August 2017 issue of ICES Journal of Marine Science:

The spawning dynamics of Atlantic cod (Gadus morhua) on Georges Bank and Nantucket Shoals are not well understood. To address this uncertainty, we combined Fishermen’s Ecological Knowledge (FEK) with traditional scientific data to develop a more holistic understanding of cod spawning on Georges Bank. Data from historical reports, trawl surveys, fisheries observers, and ichthyoplankton surveys were used to describe the spatial and temporal distribution of cod spawning activity. We also collected FEK regarding cod spawning dynamics through semi-structured interviews (n = 40). The fishermen had detailed knowledge of the spatial and temporal distribution of cod spawning, and identified persistent fine-scale (i.e. <50 km2) spawning grounds that were often associated with specific habitat features, including spawning grounds that were previously unreported in the scientific literature. The spawning seasons and locations identified by fishermen generally agreed with information from traditional scientific data, but it was evident that seasonal scientific surveys lack the spatial and temporal resolution needed to fully characterize the distribution of cod spawning activity. Our results will help inform management measures designed to promote the rebuilding of Georges Bank cod, and also provide a basis for further investigations of cod spawning dynamics and stock structure.
