Researchers Find Bright Sides to Some Invasive Species

October 16, 2o18 — Off the shores of Newfoundland, Canada, an ecosystem is unraveling at the hands (or pincers) of an invasive crab.

Some 1,500 kilometers (930 miles) to the south, the same invasive crab — the European green crab — is helping New England marshes rebuild.

Both cases are featured in a new study that shows how the impacts of these alien invaders are not always straightforward.

Around the world, invasive species are a major threat to many coastal ecosystems and the benefits they provide, from food to clean water. Attitudes among scientists are evolving, however, as more research demonstrates that they occasionally carry a hidden upside.

“It’s complicated,” said Christina Simkanin, a biologist at the Smithsonian Environmental Research Center, “which isn’t a super-satisfying answer if you want a direct, should we keep it or should we not? But it’s the reality.”

Simkanin co-authored a new study showing that on the whole, coastal ecosystems store more carbon when they are overrun by invasive species.

Take the contradictory case of the European green crab. These invaders were first spotted in Newfoundland in 2007. Since then, they have devastated eelgrass habitats, digging up native vegetation as they burrow for shelter or dig for prey. Eelgrass is down 50 percent in places the crabs have moved into. Some sites have suffered total collapse.

That’s been devastating for fish that spend their juvenile days among the seagrass. Where the invasive crabs have moved in, the total weight of fish is down tenfold.

The loss of eelgrass also means these underwater meadows soak up less planet-warming carbon dioxide from the atmosphere.

In Cape Cod, Massachusetts, the same crab is having the opposite impact.

Off the coast of New England, fishermen have caught too many striped bass and blue crabs. These species used to keep native crab populations in check. Without predators to hold them back, native crabs are devouring the marshes.

Ropes are latest flashpoint in tug of war over endangered right whales

October 15, 2018 — The lobster industry is willing to consider switching to weaker rope to protect the endangered right whale from deadly entanglements, but whale defenders say that doesn’t go far enough to help a species that can’t bear even one more death.

A team of scientists, regulators, animal rights groups and fishermen met this week in Providence to review proposals to help a species that has dwindled to about 450 individuals after coming back from the brink of extinction.

The team is advising the National Marine Fisheries Service on how to prevent whales from getting entangled in fishing gear as they migrate, feed and mate as they travel back and forth along the East Coast of the United States and Canada.

The team agreed on a lot of measures that could help them understand why the whales are dying, like putting distinctive marks on all fishing gear so regulators can know which fisheries pose the biggest threat, but not on how to actually stop entanglement deaths.

Led by Maine regulators and fishermen, the lobster industry agreed Friday to explore weaker vertical lines – the rope that links seabed traps to a surface buoy – in areas where whales gather in numbers or eat, an act that puts them at greater risk of a fatal entanglement.

Rope strength limits would represent “a giant step forward,” lobster industry officials said.

“We pushed ourselves way beyond our comfort zones to present this idea with a bow on it,” said Patrice McCarron, director of the Maine Lobstermen’s Association. “Let’s get the low-hanging fruit and find gear that we could actually fish and get in the water.”

9 countries and the EU protected the Arctic Ocean before the ice melts

October 12, 2018 —  It’s easy to miss the truly historic nature of the moment.

Last week, nine countries—the U.S., Canada, Russia, Norway, Greenland/Denmark, China, Japan, Iceland, South Korea, and the European Union (which includes 28 member states)—signed a treaty to hold off on commercial fishing in the high seas of the Arctic Ocean for at least 16 years while scientists study the potential impacts on wildlife in the far north. It was an extraordinary act of conservation—the rare case where major governments around the world proceeded with caution before racing into a new frontier to haul up sea life with boats and nets. They set aside 1.1 million square miles of ocean, an area larger than the Mediterranean Sea.

But to really grasp the significance of this milestone, consider why such a step was even possible, and what that says about our world today. For more than 100,000 years the central Arctic Ocean has been so thoroughly covered in ice that the very idea of fishing would have seemed ludicrous.

That remained true as recently as 20 years ago. But as human fossil-fuel emissions warmed the globe, the top of the world has melted faster than almost everywhere else. Now, in some years, up to 40 percent of the central Arctic Ocean—the area outside each surrounding nation’s 200-nautical-mile exclusive economic zone—is open water in summer. That hasn’t yet been enough to make fishing attractive. But it is enough that boats may be lured in soon.

So, for perhaps the first time in human history, the nations of the world set aside and protected fishing habitat that, for the moment, does not even yet exist. The foresight is certainly something to applaud. But it’s hard to escape the fact that the international accord is a tacit acknowledgment—including by the United States, which is moving to back out of the Paris climate accords—that we are headed, quite literally, into uncharted waters.

“The Arctic is in a transient state—it’s not stable,” Rafe Pomerance, a former State Department official who once worked on Arctic issues and now chairs a network of Arctic scientists from nongovernmental organizations and serves on the polar research board of the National Academy of Sciences, said last year.

Measures to protect North Atlantic right whales have been effective, official says

October 9, 2018 — Representatives of the fishing industry and Fisheries and Oceans Canada met in Moncton over the weekend to look at the impact protection measures were having on the North Atlantic right whale — and to help decide what should happen next year.

The 2018 fishing season has been controversial, with fishermen in the Acadian Peninsula protesting the new federal measures that were put in place to protect the North Atlantic right whale.

Some of those measures included closing several fisheries where whales were present in the Gulf of St. Lawrence, speed restrictions for boats and increased surveillance.

“I think it was huge this year, the collaboration. The fishermen were very good at monitoring the management measures,” said Serge Doucet, regional director of Fisheries and Oceans Canada for the Gulf of St. Lawrence, speaking in French.

Doucet noted that no North Atlantic right whales died in Canadian waters this year from entanglements or collisions with fishing boats.

And although there have been some interactions with whales this year, the department believes that measures to protect right whales have been effective so far.

“There were challenges, it was not easy for all fishermen,” he said. “But their commitment to protect whales is there.”

US Fishermen Lose Quota in New Fishing Pact With Canada

October 4, 2018 — American fishermen are losing thousands of pounds of valuable fishing quota under a new catch share agreement with Canada.

Fishermen from the U.S. and Canada seek haddock, cod and flounder on Georges Bank, which is a critical fishing ground east of New England, The two countries craft a catch share agreement every year. Under the latest agreement, the U.S.’s eastern Georges Bank cod quota is falling by more than 25 percent to about 415,000 pounds and the eastern Georges Bank haddock quota is falling by about 4 percent to about 33 million pounds.

Yellowtail flounder on Georges Bank is also falling by about half, to about 230,000 pounds. The U.S. gets 76 percent of the flounder quota while Canada gets 71 percent of the cod quota and the haddock is divided evenly.

The loss in quota will present a hardship for New England fishermen, who are already coping with low cod quotas and the collapse of the cod stock, said Terry Alexander, a longtime Maine fisherman and member of the regulatory New England Fishery Management Council that approved the catch share agreement last week.

“It’s going to be tough to get by with for sure,” Alexander said. “Cod seems to be in the cellar and yellowtail is even deeper in the cellar.”

The proposed quotas are based on historical catches and trawl surveys. Canada’s quotas are also proposed to decline. The quotas were recommended by U.S./Canada Transboundary Management Guidance Committee, which is a panel made up of government and industry members that includes representatives from both countries.

Seafood industry leaders reviewing new USMCA trade pact

October 2, 2018 — The day after U.S. and Canadian government officials announced a deal on a new trade agreement, seafood industry leaders from the neighboring countries expressed optimism about the accord, albeit with some uncertainty as they still pore over the details.

Canada’s participation, which was confirmed late in the evening of 30 September, means a new deal will replace the North American Free Trade Agreement, the accord governing trade between the U.S., Canada and Mexico for the past two decades. In late August, Mexican and American officials had reached a tentative agreement on a new deal.

“Today, Canada and the United States reached an agreement, alongside Mexico, on a new, modernized trade agreement for the 21st Century: the United States-Mexico-Canada Agreement (USMCA),” U.S. Trade Representative Robert Lighthizer said in a joint statement with Canadian Foreign Affairs Minister Chrystia Freeland. “USMCA will give our workers, farmers, ranchers and businesses a high-standard trade agreement that will result in freer markets, fairer trade, and robust economic growth in our region.  It will strengthen the middle class, and create good, well-paying jobs, and new opportunities for the nearly half billion people who call North America home.”

Officials from the Fisheries Council of Canada received a high-level briefing on the USMCA on 1 October.

“We look forward to this apparent deal to help heal our trading relationship with the US and lead to more trading opportunities in the future,” said Paul Lansbergen, council president, in an email to SeafoodSource.

The desire to revamp NAFTA has been one leg of a global trade strategy by the administration of U.S. President Donald Trump. That strategy has also included numerous proposals to raise tariffs on Chinese imports, including numerous seafood products, as the president seeks to reduce the trade deficit.

The National Fisheries Institute has lobbied heavily in recent months that tariffs on seafood products hurt U.S. jobs as the country imports more than 90 percent of the seafood Americans consume.

We can help you fight fish fraud – for starters, buy local

October 1, 2018 — The path most of the seafood imported into the United States travels from its source to the consumer is long in terms of distance, complicated in terms of the number of middlemen and women and transformative because whole fish become fillets, shrimp become scampi and crab become cakes.

Seafood fraud happens when somewhere along the way, the fish, shellfish and their parts get intentionally mislabeled, swapped out or plumped up for the seller’s gain. In the massive international seafood market – some estimates value it at $130 billion – seafood fraud happens a lot.

In 2013, the seafood industry watchdog group Oceana found that one-third of the 1,200 seafood samples it tested were mislabeled.

In 2015, an INTERPOL–Europol investigation reported that fish traded internationally was the third highest risk category of foods (alcohol and red meat beat it out) with the potential for fraud. And Oceana’s most recent study in Canada last year revealed that 44 percent of 382 seafood samples tested from five Canadian cities did not meet the Canadian Food Inspection Agency’s labeling requirements.

NOAA Memorandum on Whales Lays Basis for Much Stricter Regulation of Trap Fisheries

September 28, 2018 — SEAFOOD NEWS — A recent technical memorandum from NOAA on right whale recovery in 2018 could push the agency to require new limits on trap fishing technology.

In short, the memorandum says that the measures adopted to reduce the number of rope lines in the water have backfired.

Although the number of lines to individual buoys have been reduced, the remaining trawl strings have more traps and stronger rope.

The result is that whales are suffering more for entanglements than they were before the new rules were introduced.

The memorandum says that “stronger rope contributed to an increase in the severity of entanglements.”

“Knowlton et al.(2012) showed that nearly 85% of right whales have been entangled in fishing gear at least once, 59% at least twice, and 26% of the regularly seen animals are entangled annually. These findings represent a continued increase in the percentage of whales encountering and entangling in gear, which grew from to 61.5% in 1995 (Hamilton et al. 1998), to 75.6% in 2002.”

“Rough estimates are that approximately 622,000 vertical lines are deployed from fishing gear in U.S. waters from Georgia to the Gulf of Maine. Notably until spring of 2018, very few protections for right whales were in place in Canadian waters. In comparison to recent decades, more right whales now spend significantly more time in more northern waters and swim through extensive pot fishery zones around Nova Scotia and into the Canadian Gulf of St. Lawrence (Daoust et al. 2018).

Taken together, these fisheries exceed an estimated 1 million vertical lines (100,000 km) deployed throughout right whale migratory routes, calving, and foraging areas.”

“Each vertical line out there has some potential to cause an entanglement. With a 26% annual entanglement rate in a population of just over 400 animals, this translates to about 100 entanglements per year.”

The problem is that sub-lethal entanglements can impact the reproductive success of the population.

“While serious injuries represent 1.2% of all entanglements, there are often sublethal costs to less severe entanglements. Should an entanglement occur but the female somehow disentangles and recovers, it still has the potential to reset the clock for this “capital” breeder. She now has to spend several years acquiring sufficient resources to get pregnant and carry a calf to term, the probability of a subsequent entanglement is fairly high, and this will create a negative feedback loop over time, where the interval between calving becomes longer. This is certainly a contributing factor in the longer calving interval for females, which has now grown from 4 to 10 years.

The implication of this technical report is that substantial reductions in entanglements will be necessary if the long term decline in the population is to be reversed, and under the endangered species act, NOAA will be required to evaluate any actions that increase harm or fail to mitigate harm to the right whale population.

US companies accused of dumping lobster in Asia

September 28, 2018 — An executive with a Chinese seafood conglomerate has accused U.S. lobster companies of dumping their products on other Asian markets at steep discounts.

Jack Liu, the Halifax, Nova Scotia, Canada-based, North American president of Chinese seafood company Zoneco, which owns the lobster-focused Capital Seafood, told the Canadian Broadcasting Company the dumping was a response to newly-imposed tariffs closing off the Chinese market to U.S. exporters.

“They are going to dump those amounts of lobster into other parts of the world,” Liu said. “We have seen that.”

Liu said U.S. lobster – often labeled as Boston lobster – is selling for at least a USD 1.00 (EUR 0.85) per pound less in Hong Kong, Malaysia, and Taiwan, putting pressure on Canadian lobster exporters.

“I believe Canadian lobster, as we speak, is somewhat losing market share in those Asian markets due to the lower price from the U.S.,” he said.

While Canadian exports to China have risen in the short-term, Liu said he is not comfortable with the situation.

“Tariffs have never been a good thing. Any sort of tariffs are going to distort and disrupt the markets and we’ve already seen that,” Liu said.

Unprecedented experiment with Canadian military provides new insights on right whales

September 27, 2018 — North Atlantic right whales began making headlines the summer of 2017 when a record number of the whales died after getting tangled in fishing gear or hit by ships.

Before the die-off and since, Dalhousie researchers have collaborated with a number of partners in Canada and the United States to gain as much insight as possible on the endangered species. After a significant number of the whales began deserting other habitats off the coast of Nova Scotia in favour of a location in the southern region of the Gulf of St. Lawrence, experts recognized the lack of scientific evidence required to best inform marine management measures in this newly identified habitat.

That’s why members of the Whale Habitat and Listening Experiment (WHaLE) team in Dalhousie’s Department of Oceanography have been working tirelessly to fill the knowledge gap. In one experiment this past summer, they helped bring together a number of federal agencies in an effort to collect the most multi-faceted dataset on the North Atlantic right whales yet.
