Less Effort, More Lobster? New Research Suggests That Fewer Traps Can Still Yield Profitable Results

June 1, 2020 — New research suggests that the U.S. lobster industry could place fewer traps in the water and still gain just as much profit. And that finding could play a role in the debate over what should be required of Maine lobstermen to reduce entanglements with endangered North Atlantic right whales.

The study was published this week in the peer-reviewed Marine Policy Journal. Lead researcher Hannah Myers is a graduate student at the University of Alaska’s College of Fisheries and Ocean Studies. She took a close look at landings and other data from lobster-fishing territory that crosses the international Hague Line between Nova Scotia and Maine.

“We found that Canadian fishers in the Gulf of Maine caught about the same amount of lobster using seven and a half times less effort than Maine fishers on the U.S. side,” she says.

The researchers found that while the Canadians spent fewer days at sea and fished fewer traps, the traps they pulled had almost four times as many lobsters in them.

Lobstermen don’t need all the traps they use, research claims

May 29, 2020 — New research suggests that the U.S. lobster industry could place fewer traps in the water and still gain just as much profit. And that finding could play a role in the debate over what should be required of Maine lobstermen to reduce entanglements with endangered North Atlantic right whales.

The study was published this week in the peer-reviewed Marine Policy Journal. Lead researcher Hannah Myers, a graduate student at the University of Alaska’s College of Fisheries and Ocean Studies, examined landings and other data from lobster-fishing territory that crosses the international Hague Line between Nova Scotia and Maine.

Myers’ research might help to end an impasse between animal-rights activists who are looking to reduce entanglements injurious, if not fatal, to the whales and have said that Maine fishing lines are at least a statistically-significant threat to the creatures. Maine lobstermen criticize activists and researchers as advancing poorly-researched and economically damaging arguments to their way of life. A plan recently advanced by Maine fishermen was criticized by researchers as not going far enough, while Maine’s federal and state government leaders have called on the federal government to back down on encroaching upon Maine lobstermen.

Researchers Probe Orca Poop for Microplastics: Part 2

May 21, 2020 — The following was released by NOAA Fisheries:

How do microplastics end up in killer whale feces?

“There are two ways that the whales could ingest microplastics,” says Kim Parsons, Research Geneticist with NOAA Fisheries’ Northwest Fisheries Science Center. “They could incidentally swallow particles in sea water while eating fish, or they could ingest salmon that are themselves contaminated with microplastic particles.”

She suspects that most of the microplastics in orca poop are coming from the whales’ prey. The particles are traveling up the food chain from gut to gut, from herring to salmon to orca.

But why does it matter for orcas if their guts are full of microplastic particles and fibers?

How ingestion of microplastics affects marine mammals is both poorly understood and scientifically controversial. So the answer is, we don’t know yet, but scientists are concerned for the health of organisms at all levels of the marine food chain.

You might own a reusable water bottle advertised as being free of toxic chemical additives like bisphenol A, or BPA. Many chemicals found in microplastics are pollutants, such as polyethylene, polypropylene, phthalates, and BPA and its substitutes. Some of these chemicals are known endocrine disruptors, which means that the chemicals can disrupt an animal’s natural hormones. The chemicals may affect reproduction, growth and development, and ultimately population viability. When microplastics are moving through the whales’ digestive tract, the harmful chemicals could leach into their bodies.

Researchers Probe Orca Poop for Microplastics: Part 1

May 19, 2020 — The following was released by NOAA Fisheries:

You might worry about your toddler chewing on a plastic toy with toxic chemicals. Some orca researchers are beginning to worry about whales ingesting a gut full of microplastics, and what that might mean for their health.

Microplastics are everywhere. Millions of tons of plastic enter our oceans annually, and much of it breaks into tiny pieces. Microplastics are plastic particles five millimeters (about two-tenths of an inch) or smaller. They represent 92 percent of plastic pieces polluting the oceans’ surface waters. Researchers have found microplastics in all major seas and oceans. They’ve also found them in the intestinal tracts of organisms at all levels of the ocean food chain, from zooplankton to fish to marine mammals.

Some scientists are concerned that microplastics and their toxic effects are bioaccumulating in killer whales, the oceans’ top predators. Endangered Southern Resident killer whales spend much of their summers in Puget Sound and the Salish Sea. Chemical contamination from pollution, particularly in young whales, is one of three primary threats to their population. Could microplastics be part of the problem?

A team of scientists with NOAA Fisheries’ Northwest Fisheries Science Center (Center) and the University of Washington have started an investigation. They are looking at what microplastics the Southern Residents are ingesting, at what scale, and whether the whales are being exposed to toxic chemicals associated with microplastics.

Conservation groups seek vertical line ban off Massachusetts coast

May 19, 2020 — The conservation groups that filed a federal lawsuit two years ago to force the National Oceanic and Atmospheric Administration to do more to protect endangered right whales from entanglement with fishing gear have asked U.S. District Court Judge James E. Boasberg to ban lobster fishing gear with vertical buoy lines off the coast of Massachusetts.

The affected area would be south of the islands of Martha’s Vineyard and Nantucket.

According to the Center for Biological Diversity and several other plaintiff conservation groups, the area “has increasingly become important right whale foraging and socializing habitat in recent years.”

The conservation groups filed their request last Friday, three weeks after the judge ruled that the National Marine Fisheries Service (NMFS) violated the federal Endangered Species Act when it continued to allow lobster fishing with gear that used fixed vertical buoy lines in which whales could become entangled.

As a practical matter, a ban on the vertical lines that connect traps on the sea floor to marker buoys on the surface would amount to a total prohibition against lobster fishing in the area south of the two Massachusetts islands.

New rules for California Dungeness crab fleet seek fewer whale entanglements

May 18, 2020 — The California Department of Fish and Wildlife on Friday unveiled a batch of complex new rules designed to reduce the risk to endangered whales and sea turtles of becoming entangled in commercial Dungeness crab fishing gear.

The draft regulations are set to be finalized before the next commercial season starts in November after a period of public review.

They expand on a framework established under a legal settlement reached last year that allows for the state’s $60-million-a-year crab fishery to be delayed or closed when surveys and other observations suggest a high risk of concentrated fishing gear and marine life overlapping in the same place. The new rules are meant to allow more nuanced risk assessment and precise management actions rather than the closure of large swaths of ocean, as seen in recent seasons.

Among the provisions are options to restrict fishing in certain depths, require crabbers to set only a share of the traps for which they’re permitted or limit intervention to any of six newly established geographic zones, rather than the larger Northern and Central California management districts that currently exist.

Killer Whale Recovery Begins With Salmon Habitat, and That Begins With You

May 12, 2020 — The following was released by NOAA Fisheries:

Consider this Northwest twist on a familiar saying: “Give a killer whale a salmon, and it will eat for a day. Restore the habitat the salmon and whales depend on, and they will live for generations to come.” At NOAA Fisheries we are determined to get more Chinook salmon to the endangered Southern Resident killer whales, and that begins with more and better habitat.

It is up to everyone to maintain room for these magnificent creatures as our own footprint on the Puget Sound region grows ever bigger.Focusing on salmon habitat is essential.

Improving Salmon Habitat

Washington Governor Jay Inslee’s Orca Task Force emphasized habitat. It highlighted actions such as removing culverts that block salmon migration, protecting shoreline habitat, and building on other efforts throughout the region. We must work together to restore the streams where salmon spawn and grow, and protect the dwindling nearshore habitat that shelters and nourishes juveniles.

Improving fish passage through dams must continue. It is important to get salmon into their prime habitat.

Through partnerships, we’ve made progress in recent years on these goals. Restored habitat in the Skagit River estuary, funded in part by the Pacific Coastal Salmon Recovery Fund, now supports hundreds of thousands more Chinook salmon smolts. The U.S. Army Corps of Engineers is constructing fish passage at Mud Mountain Dam, renewing access to miles of habitat in the White River. The Nisqually Tribe led one of Puget Sound’s most ambitious tidal marsh restoration efforts in the Nisqually River Delta—just to name a few.

Lobstering group wants to raise $500,000 for legal defense fund

May 7, 2020 — The Maine Lobstermen’s Association has launched a campaign to raise $500,000 to fund its legal efforts to protect the state’s most valuable fishery from the consequences of a recent federal court ruling that calls for more government protections for the endangered right whale.

Last month, a federal judge found the National Marine Fisheries Service had violated the U.S. Endangered Species Act by its authorization of the U.S. lobster industry – including Maine’s $485 million-a-year fishery – because it failed to report the fishery’s harmful impacts on the endangered right whale.

“This case could lead to closure of the world’s most sustainable fishery,” said executive director Patrice McCarron, whose association is the oldest and biggest lobstering group in Maine. “We cannot let that happen. Right whales are not dying in Maine lobster gear.”

Maine Lobstermen’s Association Asks For Public Donations To Help ‘Save’ The Industry

May 7, 2020 — The Maine Lobstermen’s Association is calling for a half-million dollars in public donations to help it “save” the state’s lobster industry from potential extinction.

The MLA says the money would go to its legal defense of the fishery in a federal court case brought by conservationists who want better protections of the endangered North Atlantic right whale.

The whales can be injured or killed by entanglement with rope used to tend trap-pot gear, such as lobster traps. But the MLA’s Executive Director Patrice McCarron says there is no proof that the whales are actually interacting with traps set by the Maine fleet.

Lobstermen launch campaign to save Maine industry; new threats on the horizon

May 6, 2020 — The Maine Lobstermen’s Association is fighting a federal ruling that threatens the demise of the fleet, according to Patrice McCarron, executive director of the Maine Lobstermen’s Association.

In early April, Judge James Boasberg of the Federal District Court for Washington, D.C., ruled that NMFS violated the ESA in permitting the lobster fishery. The judge’s opinion states that “Congress enacted the ESA in 1973 to halt and reverse the trend toward species extinction, whatever the cost.”

“The MLA has launched a campaign to raise $500,000 to save Maine’s lobster industry,” McCarron said. The MLA is an intervenor in the court case and is the only organization in Maine that has been granted standing to participate in the case.

Whale entanglement data collected by NMFS show that no right whale deaths or serious injuries have ever been documented in Maine lobster gear. This is in stark contrast to the death of 10 right whales in Canada last year.
