Colder waters off West Coast mark end of “the blob”

August 28, 2019 — Record high Pacific Ocean temperatures recorded off the West Cost in recent years have receded to near normal, according to a report on the California Current.

That cool shift marks the end of “the blob,” the mass of warm water that dominated the West Coast, and of the El Nino event that followed. It’s unclear, however, what that means for fish and marine mammals, scientists with the National Oceanic and Atmospheric Administration stated in the 2019 ecosystem status report for the California Current Ecosystem.

“The big thing is that a lot of the physical conditions of the ocean here off of our coast are beginning to return to normal,” said Elliott Hazen,” a research ecologist with NOAA’s Southwest Fisheries Science Center. “But it is not clear yet whether the ecosystem is as well.”

Climate change: NJ is warming faster than most of the country

August 26, 2019 — The New Jersey lobster boom has passed.

Tom Fote, legislative chairman for The Jersey Coast Anglers Association, recalls a time in the 1990s when warming waters off the Jersey Shore prompted the tasty crustaceans to reproduce more, attracting more boats to fish for them.

But then the water got too hot. The lobsters stopped reproducing as they had been.

“We were the canaries in the mines,” Fote said of anglers in New Jersey.

New Jersey has emerged as a top state in the nation experiencing climate change, according to a new analysis of climate data by The Washington Post. 

New Jersey heated by nearly 2 degrees Celsius, or 3.6 degrees Fahrenheit, since about the turn of the last century, the Post found. That’s double the average for the continental United States. Alaska, then Rhode Island crossed the 2-degree mark, the Post reported. New Jersey is close.

Suppressed federal report shows how Trump water plan would endanger California salmon

August 22, 2019 — Federal officials suppressed a lengthy environmental document that details how one of California’s unique salmon runs would be imperiled by Trump administration plans to deliver more water to Central Valley farms.

The July 1 assessment, obtained by the Los Angeles Times, outlines how proposed changes in government water operations would harm several species protected by the Endangered Species Act, including perilously low populations of winter-run salmon, as well as steelhead trout and killer whales, which feed on salmon.

But the 1,123-page document was never released.

California king salmon rebounds after drought

August 22, 2019 — California fishermen are reporting one of the best salmon fishing seasons in years, thanks to heavy rain and snow that ended the state’s historic drought.

It’s a sharp reversal for chinook salmon, also known as king salmon. The iconic fish helps sustain many Pacific Coast fishing communities.

A marine scientist with California’s fish and wildlife agency says commercial catches have so far surpassed official preseason forecasts by roughly 50%.

Longline fishing hampering shark migration

August 21, 2019 — Longline fisheries around the world are significantly affecting migrating shark populations, according to an international study featuring a University of Queensland researcher.

The study found that approximately a quarter of the studied sharks’ migratory paths fell under the footprint of longline fisheries, directly killing sharks and affecting their food supply.

Dr Bonnie Holmes, from UQ’s School of Biological Sciences, wanted to find out why shark numbers have been declining significantly over the past 20 years.

“We’re losing these incredible creatures, and we know so little about shark movements and what drives them,” she said.

“I joined an international research effort, using new technologies — like satellite tracking and big data analysis — to help answer some critical questions.”

Study finds fishermen who venture to new grounds benefit

August 21, 2019 — In 2009, excessive bycatch of endangered sea turtles in the Gulf of Mexico prompted a five-month closure of the Gulf’s longline fishery. Boat captains unexpectedly found themselves locked out of prime fishing grounds, and were forced to look elsewhere to make a living.

As it turned out, some captains fared better than others in this endeavor. And their experience has implications for fishermen today who are adapting to changing environmental and regulatory conditions.

Warm, dry weather causing abnormalities in Bristol Bay’s salmon runs

August 21, 2019 — The world’s largest sockeye fishery, Bristol Bay, Alaska, clocked its second-largest harvest ever this season, with a haul of more than 43 million fish. The big catch, combined with a robust base price – most of the fishery’s major processors have posted an initial ex-vessel buying price at USD 1.35 (EUR 1.20) per pound – should make 2019 among the most lucrative years in the fishery’s history. This season’s historic catch comes after a string of abnormally large runs, including last season’s 62.3 million salmon, the largest in Bristol Bay’s history.

But despite a string of productive runs that have surpassed forecasts, some biologists and fishermen are concerned about warm, dry weather that has pumped up water temperatures in the region.

FAO paper predicts impact of climate change on world’s fisheries, aquaculture

August 20, 2019 — Climate change will decrease the world fisheries’ overall maximum catch potential between 2.8% and 12.1% by 2050 based on different greenhouse gas emission scenarios, with the tropics, especially the South Pacific region, getting hit the hardest, says a team of technical experts organized by the United Nations’ Food and Agriculture Organization (FAO).

It’s not just the oceans either. As water becomes more scarce, inland fisheries will be undervalued. Pakistan, Iraq, Morocco and Spain are all highlighted as countries that are currently facing high stresses that are projected to become even higher in the future.

Blooms, beasts affected as Alaska records hottest month

August 19, 2019 — Alaska has been America’s canary in the coal mine for climate warming, and the yellow bird is swooning.

July was Alaska’s warmest month ever, according to the National Oceanic and Atmospheric Administration.

Sea ice melted. Bering Sea fish swam in above-normal temperatures. So did children in the coastal town of Nome. Wildfire season started early and stayed late. Thousands of walruses thronged to shore.

Unusual weather events like this could become more common with climate warming, said Brian Brettschneider, an associate climate researcher at the University of Alaska Fairbanks’ International Arctic Research Center. Alaska has seen “multiple decades-long increases” in temperature, he said.

APPLICATIONS DUE THURSDAY, 8/22: October 2019 Workshop to Identify Research Priorities for Shifting Marine Species

August 19, 2019 — The following was released by Lenfest Ocean Program:

The shifting distribution of marine species is one of the most visible impacts of climate change on the world’s oceans. Scientists, fishermen and others on the East and West Coasts of the United States have observed range shifts that have disrupted species ecology, fishing patterns and management strategies. In every region of the US, fish populations are projected to shift further as ocean temperatures continue to warm.

Open Call for Participants

This fall, the Lenfest Ocean Program, in collaboration with the David and Lucile Packard Foundation and the Biodiversity Funder’s Group, will host a three-day Ideas Lab workshop to bring together scientists, managers, stakeholders, and funders for a collaborative discussion about the future of fisheries in the face of climate change. The workshop, which will take place from October 21-23, 2019, in Washington, DC, will aim to generate research priorities and kickstart the funding of key research projects.

We are seeking individuals with local knowledge, scientific expertise, insights or specific perspectives who are interested in a collaborative, interdisciplinary Ideas Lab designed to generate priority research questions for funding consideration. An Ideas Lab is an intensive meeting that brings together multiple diverse perspectives to focus on finding innovative cross-disciplinary solutions to a critical problem.
