Six Right Whale Deaths In One Month: ‘Panicking Seems Appropriate’

July 3, 2019 — Five North Atlantic right whales have been found dead in the past week, and six in the last month. With just over 400 remaining and calving rates low, that’s a death toll the critically endangered population can’t afford.

“Panicking seems appropriate, yes,” said Peter Corkeron, who leads the large whale research program at NOAA’s Northeast Fisheries Science Center.

The whales’ death toll is similar to that of the summer of 2017, when there was one death in early June, and then, later in the month, five deaths in the span of a week, all in the Gulf of St. Lawrence. That summer went on to become catastrophic for the whales, with a total of 12 documented fatalities in Canadian waters and another six in U.S. waters.

There are notable differences, as well, though. In 2017, some whales were hit by ships, but many of the deaths were due to whales getting tangled in fishing gear. This year, ship strikes seem to be the primary problem.

Large numbers of North Atlantic right whales have been sighted in the western Gulf of St. Lawrence in recent summers. Corkeron says that may be because of a subtle shift in where the animals are spending their time. Right whales have only started showing up in the Gulf of St. Lawrence in significant numbers in the past few years, a change in their migration patterns that researchers attribute to climate change.

Shellfish growers are feeling climate change’s effects now

July 3, 2019 — Shellfish farming in Washington is a multimillion-dollar industry with a history as deep as Puget Sound. However, recent decades of warming oceans and higher levels of ocean acidification continue to challenge shellfish farming practices.

In and around Whatcom County there are several aquaculture farms, such as Lummi Shellfish Hatchery, Drayton HarborOyster Co., Blau Oyster and Taylor Shellfish in Samish Bay. Each farm varies in size, number of employees and type of shellfish produced, but they share one thing in common: the water quality of Puget Sound.

There are more than 300 aquaculture farms across Washington, according to the Pacific Shellfish Institute. A WashingtonState Maritime Sector Economic Impact Study in 2017 found that the industry directly supports 15,900 jobs. Samish Bay shellfish farms alone include $2 million annual payroll and $6 million in wholesale oysters, clams and geoduck.

In June, four ocean acidification bills made bipartisan progress, in the U.S. House of Representatives and Senate, to becoming law. The bills are designed to encourage research and spur new ideas for adapting to the affects of ocean acidification. The bills include the COAST Research Act of 2019, the Coastal Communities Ocean Acidification Act of 2019,the Ocean Acidification Innovation Act of 2019 and the NEAR Act of 2019.

As carbon dioxide is emitted into the atmosphere a certain percentage is absorbed into the water, causing a chemical reaction that makes the water more acidic. According to the National Ocean and Atmospheric Administration, roughly 25%of carbon dioxide emissions are absorbed into the worlds oceans. The process is similar to bubbles escaping from a soda can, but in reverse. Since the industrial revolution ocean acidification has increased by 30% and reduced carbonate ions by16%, said Bill Dewey, director of public affairs for Taylor Shellfish. By the end of the century it is predicted that ocean acidification will increase by 100% to 150% and reduce carbonate ions by 50%, said Dewey.

ALASKA: Bristol Bay’s Salmon Flood is Rising — the Greatest Migration on Earth?

July 2, 2019 — SEAFOOD NEWS — As sockeye salmon surge past the Port Moller Test Fishery nets and catch tallies in the Bay rise as escapment numbers in the river systems accelerate even faster (after all, that is what the biologists manage for), the vast size of Bristol Bay’s salmon run is hard to grasp.

The six-week fishery, which reaches a fever pitch for about ten days, is arguably the greatest migration on earth. Because it is invisible until the last few days, it is rarely recognized. Great migrations might bring to mind vast herds of wildebeast crossing the Serengeti in Africa; those number a mere 1.5 million.

Then there’s what many now call the largest mammal migration — fruit bats from the Congo to neighboring Zambia over 90 days each fall. The size? Only 10 million.

This year’s forecasted total run of 40.18 million sockeyes is expected to net a harvest of 26.1 million salmon.

It’s difficult to find, by any measure, a likeness in the natural world of the journey Bristol Bay salmon make from one of the Bay’s five river systems to the ocean, across the Bering Sea and North Pacific Ocean in a vast loop that brings them back to the Bay to reproduce and die.

It is the reproduction part that fisheries managers focus on. Indeed, state law requires them to manage for escapement to maintain sustainability for each species and timing in each salmon river, every year.

Escapement in the Wood and Nushagak rivers of Bristol Bay is tracking well with forecasts made by the Alaska Department of Fish and Game pre-season. As of yesterday, June 30, Wood River escapement was 603,000 sockeye out of a forecasted escapement of 980,000, putting it at the 61 percent mark. In the Nushagak a cumulative escapment of 243,000 sockeye have been counted, 32 percent of the 770,000 expected.

That is good news, but even better news is when compared to last year’s escapement on that date, escapement on the Nushagak this year is higher. And remember that last year the Nushagak District salmon run broke all historic records. On July 1, 2018, ADF&G broke the news that harvest in the Nushagak reached 1.77 million sockeye, a new record. Their escapment at that time was 183,440 sockeye out of a predicted 770,000 salmon (same as this year.)

The Wood River escapement last year at this time was 1.2 million out of a prediction of 1.53 million or 78 percent acheived. The Wood River is part of the Nushagak District, and last year was a huge contributor to the record-breaking district totals.

Historically, Bristol Bay’s peak is coming at the end of this week. The latest analysis from the Port Moller Test Fishery notes “The substantial uptick in the daily index today [June 29, 2019] indicates the run will continue to build at least through July 4, and possibly beyond.

“We will need to know what the remainder of the test fishing indices look like to see how big the run may be beyond July 4 (we only predict the catch plus escapment that is between Port Moller and the inshore districts). The daily C+E will likely bounce around our current projection but should total around 8 million fish for the period June 29-July 4.”

The Port Moller team also notes that there is no indication that the run is early.

“If the run is on time, the index should begin to fall tomorrow [Sunday, June 30] and continue to do so. Sustained catch indices over the next several days would indicate a later run that is larger than the pre-season forecast.”

Egegik and Nushagak Districts have dominated the test fishery at Port Moller so far, underscoring that the run has not reach its peak at Port Moller, about 5-6 days of swim time for a salmon to the Bay.

Harvest totals in the Nushagak District, as of yesterday, were 4.1 million sockeye out of a pre-season catch forecast of 7.97 million.

On the east side of the Bay, the Egegik to date harvest of 2.1 million compares to the pre-season forecast of 7.04 million.

Bristol Bay’s total catch is 6.8 million sockeye, already more than any other area in the state. Total sockeye catches are 9.6 million fish, with 1.4 million coming from the PWS/Copper River, 1.2 million from the South Peninsula.

Total salmon landings of all species in Alaska are at 22.84 million, with chums making up 3.6 million and pinks, to date, at 9.6 million.

New England Coastal Waters Warming More Than Anywhere Else In U.S.

June 27, 2019 — Waters off the coast of New England have warmed up more than any other coastal areas in the United States — up to 3 degrees Fahrenheit since 1901. That’s according to a new analysis of recently collected federal ocean data by the independent research nonprofit Climate Central.

Their report also notes that fresh and salt waters across the United States are warming 40% faster than expected.

In New England, this means changes for the fishing industry: Cold water fish are moving to deeper waters, and species from warmer climates are moving in, according to research fishery biologist Vincent Saba of the Northeast Fisheries Science Center.

“We’ve seen dramatic shifts in where fishermen are catching species today, versus where they were being caught say 15 or 20 years ago,” Saba says.

Helping New England fishing communities adapt

June 26, 2019 — New England fishing communities must adapt or fail. That’s the advice published in a new study co-authored by UMass Dartmouth scientist Dr. Robert Griffin.

Climate change is altering ocean temperatures, as researchers have previously documented, and entire fish populations are migrating further north or into deeper waters in search of cooler environments. For fishing communities, that means the slow disappearance of species that may be integral to the area’s identity.

For example, lobster in southern New England is migrating out, while black sea bass and Jonah crab have become more abundant.

“[Fishermen] all seemed to understand that this is happening,” Griffin said. “They go out and try to continue to catch the fish they’ve been trying to since they started, but it’s much harder.”

Warmer waters mess with the Northeast’s cod-given right to fish

June 24, 2019 — Fishing has been the economic and cultural pillar for many coastal towns along the Northeast coast for generations. But a warmer climate threatens the abundance and distribution of key species like haddock and Atlantic cod. And that will spell trouble for these fishing towns, according to new research.

“Fishermen need to travel farther from port to fill their nets, reflecting shifts in the location of their target species,” quantitative ecologist Lauren A. Rogers, who co-authored the study, explained.

A warmer climate makes species migrate north; the timing of species to arrive into fishing areas is shifting as well. This complicates fishermen’s jobs as they may not see a species during a time when regulations allow them to fish for it.

“Fishermen are on the frontlines of climate change,” Monique Coombs, director of marine programs at the Maine Coast Fishermen’s Association, told Grist. “Clam harvesters see the shells of the intertidal species softening because of ocean acidification. Changing weather patterns inhibits fishers’ safety because they are no longer able to depend on weather forecasts.”

A ‘long, creeping change’: As climate warms, Virginia fisheries struggle to adapt

June 24, 2019 — George Washington had few dietary preferences, save one: he was “excessively fond” of fish.

Luckily for the president, his perch at Mount Vernon afforded him an easy opportunity to indulge.

The Potomac, he recorded in 1793, was “well-stocked with various kinds of fish in all Seasons of the year, and in the Spring with Shad, Herring, Bass, Carp, Perch, Sturgeon, etc. in great abundance. … The whole shore, in fact, is one entire fishery.”

Today, Mount Vernon still overlooks the Potomac, but the species that call Virginia waters home are increasingly different due to something Washington couldn’t have foreseen: climate change.

“It’s hard to manage fisheries to begin with, [and] in the past we’ve always considered the climate stable,” said Patrick Geer, deputy chief of fisheries management for the Virginia Marine Resources Commission. “But now that theory of a stable climate and environment has been taken out.”

As global air temperatures warm, so too do global waters. The Environmental Protection Agency estimates that the temperature of the ocean’s surface has risen an average of 0.13 degrees Fahrenheit every decade since the beginning of the 20th century. And the Chesapeake Bay is estimated to be warming even faster, at an average rate of 1.2 degrees every decade since the 1980s.

Increasingly, that is making environments inhospitable for fish. In reaction, populations on the East Coast are shifting northward and eastward, leaving commercial fishermen and states who have long relied on their presence with lighter nets — and fears of lighter coffers.

Some of those fears are justified. The classic cautionary tale is that of New England’s northern shrimp fishery, which crashed precipitously around 2012 and was closed in 2014 by the Atlantic States Marine Fisheries Commission, the governmental body that oversees the management of fisheries in state waters from Maine to Florida. In February 2018, the ASMFC extended the moratorium to 2021 in an announcement that linked the collapse to warming ocean temperatures and broached the possibility of a future in which “the stock has no ability to recover.”

Such regional collapses may become more frequent in coming years, while at the same creating more favorable environments for other species.

“In any one region, some species will experience improving environmental conditions that may result in increased available habitat and increased species productivity, while other species will experience the opposite and perhaps decline in abundance,” the National Marine Fisheries Service declared in its 2015 Climate Science Strategy.

Or, as Geer put it, “For any given area and for any given species, there will be winners and losers.”

New Study Finds Surfclams Uniquely Resilient in Face of Climate Change

June 20, 2019 — The following was released by the Science Center for Marine Fisheries:

Climate change is one of the most pressing challenges facing the future of marine life, affecting everything from habitats, to migration, to spawning patterns. But new research shows that at least one species has unique features that have allowed it to adapt well to a warming ocean.

The study, published in Marine Ecology Progress Series, finds that surfclams are able to shift their range into previously inhospitable waters as the surrounding oceans temperatures rise. This information will be essential for fisheries managers struggling to effectively manage species in the face of climate change.

The key to this adaptability, according to authors Drs. Jeremy Timbs and Eric Powell, of the University of Southern Mississippi, and Dr. Roger Mann of the Virginia Institute of Marine Science, is the number of larvae that surfclams produce. Ordinarily, surfclams produce a massive amount of larvae, which end up distributed across a wide range of the ocean. Most of these larvae will die from predators, lack of food, or inhospitable temperatures. But the study found that, as ocean temperatures shift, the range of acceptable habitat shifts along with it. Larvae that would have died under cooler conditions now survive, gradually changing where surfclams are located.

“For a sedentary species, surfclams are remarkably adaptable to ocean changes that would cause problems for other shellfish,” says Dr. Powell. “This is especially important for fishermen who depend on surfclams, and who are trying to adapt with the rest of the industry to the challenges posed by climate change.”

The study, which examined 30 years worth of surfclam data, was funded through the Science Center for Marine Fisheries (SCeMFiS). A collaborative project funded through a National Science Foundation grant and support from the fishing industry, SCeMFiS funds groundbreaking research around pressing scientific issues identified by our industry partners.

“Studies like this confirm what we have been seeing since the 1990s, and help us predict the industry’s future,” said Guy Simmons, of SeaWatch International, which is one of the largest harvesters of clams in the country. “We need to work with our partners in the scientific community as we continue to adapt to a changing ocean.”

Climate change threatens commercial fishers from Maine to North Carolina

June 18, 2019 — Most fishing communities from North Carolina to Maine are projected to face declining fishing options unless they adapt to climate change by catching different species or fishing in different areas, according to a study in the journal Nature Climate Change.

Some Maine fishing communities were at greatest risk of losing their current fishing options, according to the study by Rutgers and other scientists.

“Some communities like Portland, Maine, are on track to lose out, while others like Mattituck, New York, or Sandwich, Massachusetts, may do better as waters warm,” said senior author Malin Pinsky, an associate professor in the Department of Ecology, Evolution, and Natural Resources at Rutgers University-New Brunswick. “Adapting to climate change for many communities will require fundamentally new approaches to fishing. Change has become the new normal.”

Fishing has been the economic and cultural lifeblood for many coastal towns and cities along the Northeast coast, in some cases for hundreds of years, Pinsky said. But climate change is expected to have a major impact on the distribution, abundance and diversity of marine species worldwide, the study notes.
