More than just temperature change at work as climate change hits salmon, research shows

January 17, 2020 — The four-year EU research project ClimeFish has established that there will be more factors than just water temperature at play as the full effects of climate change hit Norwegian salmon over the next five decades.

According to Elisabeth Ytteborg, a scientist at the research group Nofima, who collaborated with the UK’s University of Stirling on the project, local factors play a much bigger role than previously assumed on fish health as marine temperatures rise.

Although it has previously been determined that salmon die when water temperature hits 23°C, there has reportedly been a case that saw salmon died at a significantly lower temperature, 20°C.

Rising sea temperatures could threaten Atlantic salmon production

January 16, 2020 — In 2017, aquaculture production in the EU reached a decade high thanks to increased production of high-value species like salmon and seabass, according to a report by the European Market Observatory for Fisheries and Aquaculture Products (EUMOFA). The same report also shows that in 2015, per capita world consumption of fish was 8 percent higher than in 2005, with Asia registering the highest growth, followed by Europe.

With the consumption of fish and shellfish expected to rise further, and  change rapidly affecting fisheries and habitats, it’s crucial to analyze the dynamics of fisheries and aquaculture production. The EU-funded ClimeFish project has been tackling this issue to help regulators, fish producers and aquaculture operators to predict, prepare and adapt to climate change.

Partially supported by ClimeFish, a team of researchers found that since the 1980s,  off the Norwegian coast have risen by 1 °C on average, as noted in a news item by project partner Nofima. The researchers predict further increases over the next decades, likely causing problems for . Salmon is the third most consumed farmed fish in the EU, according to EUMOFA.

NOAA Fisheries Veterans Corps Turned My Life Around

January 15, 2020 — The following was released by NOAA Fisheries:

In 2015, I was separated from the U.S. Army with a General Discharge, Under Honorable Conditions. I returned to California with no idea what I was going to do. My hopes of attending a four-year college using the Post 9-11 G.I. Bill were squashed due to the characterization of my discharge. Over the next year, I would end up dropping out of community college and getting fired from my gas station job. My life was way off track, I lacked any purpose or vision, and I was headed nowhere fast. But this rock-bottom moment led me to a job posting for the California Conservation Corps (CCC), and my life was radically transformed in the best possible way.

I joined the CCC in July of 2016 and spent my first year in the traditional Corps program. I did activities such as litter clean up, fire fuel reduction, and invasive plant removal. The work opened my eyes to a whole new world of conservation and natural resource protection, but I felt the need to learn and do more. That’s when I requested a transfer to northern California and found out about the existence of the NOAA Veterans Corps Fisheries Program. I had no idea what “fisheries” meant or that California was home to salmon, but I liked that the job description included “working independently” and “hiking through creeks.” So, I took a leap of faith and took a position in the Vet Corps working at the Ukiah CCC Center. This turned out to be the best decision that I have ever made in my life.

Improving Habitat, Counting Salmon

Over the next two years I learned more about science and conservation than I ever did in any classroom setting. I spent three months leading a crew in the installation of “large woody debris” (a fancy science term for logs) on coastal streams. This improves the quality of habitat for endangered coho salmon.

After that, I spent about six months walking through the creeks of Sonoma and Mendocino counties. I counted spawning salmon and gathering data for biologists from the Mendocino Redwood Company and the Russian River Monitoring Program. When the salmon finished spawning, I used laser survey equipment to gather data about changes in the topography of stream channels. I spent one more season doing restoration work with the CCC before I decided to branch out once more. I transferred to the NOAA Vet Corps’ most unique site in Orleans, California.

New fish farm near Miami aims to grow major portion of U.S. salmon supply

January 13, 2020 — A new land-based salmon farm, described by industry groups as among the world’s largest, is raising millions of the healthy popular fish in giant warehouses about 30 miles southwest of Miami.

The subtropical location for the farmed salmon, which love cold northern waters, is unique in the world. The company, Atlantic Sapphire, pulls cold water from underground and keeps it at 59 degrees Fahrenheit in what it calls a bluehouse — a greenhouse for fish.

Norwegian entrepreneur Johan Andreassen built the farm in Homestead, Fla., over the past two years, relying on a steady supply of fresh and salt water from underground aquifers, he said. That’s because salmon in the wild lay eggs in freshwater rivers, and the young fish swim to salt water to grow.

Ultimately, the company wants to supply a sizable portion of the U.S. salmon market at a time when more Americans are turning to healthy fish in their diets.

Conservation group removing barrier to salmon on Maine river

January 6, 2020 — A salmon conservation group plans to remove an old hydropower station straddling the Dennys River in Maine so more alewives and Atlantic salmon can make their way upstream into Meddybemps Lake.

The abandoned hydroelectric station, built in the 1940s, sits over an artificially narrowed bottleneck in the river in Washington County.

Work on removing the structure, which does not impound any water, is expected to begin Monday, the Bangor Daily News reported.

The project is expected to allow hundreds of thousands of alewives to repopulate the lake and to support a commercial alewife fishery in the river, as well as to help sustain the river’s ecosystem, according to the Downeast Salmon Federation.

MAINE: Record number of Atlantic salmon eggs reported in Washington County river last year

January 6, 2020 — A record number of Atlantic salmon eggs were laid in the East Machias River last year, an indication that an eight-year effort to restore the endangered species in the river is paying off.

Biologists counted 61 redds, or nests that fish build for spawning, buried in several inches of river gravel spread between Crawford and East Machias. That’s six times the number of redds counted in the East Machias River since the Downeast Salmon Federation began tracking salmon egg nesting patterns there 20 years ago, said Dwayne Shaw, the federation’s executive director.

“This is just huge,” Shaw said. “A number like this hasn’t been seen in the river in decades.”

The federation counted 12 redds in 2016, four in 2017 and 10 in 2018. Over the past 20 years, the East Machias River on average has yielded about 10 redds a year.

With each redd containing about 4,000 eggs, the 61 redds are carrying about 240,000 eggs — enough, given the rigors of nature and the presence of predators, to produce about 2,000 salmon that will survive in the river over the next two years and become smolts, fish mature enough to go to sea, Shaw said.

Fishermen’s group declares “partial victory” after court ruling on GM salmon

January 3, 2020 — Even though a federal judge ruled in December that the U.S. Food and Drug Administration has the authority to regulate genetically modified salmon, a commercial fishing group that sued the agency is declaring “partial victory.”

That’s because, in May, the judge will hear arguments on the second part of the case, which questions whether the FDA’s approval of GM salmon was deficient.

Alaska’s 2019 fisheries bring new records, continued concern

January 3, 2020 — Alaska’s fisheries in 2019 had several bright spots, yet many areas of concern will return into the next year.

Once again the sockeye fishery in Bristol Bay was the shining star of the commercial sector. Fishermen caught Bristol Bay’s 2 billionth sockeye salmon since records were first kept. The in-shore run of 57 million fish clocked in at the fourth-largest run on the record books, but the ex-vessel value of $306 million ranks as the best of all time.

“We had really good fisheries out in Bristol Bay,” ADF&G Commissioner Doug Vincent-Lang said. “In Southeast Alaska we were able to meet all our treaty obligations, provide commercial fishing opportunity and most importantly protect all our stocks of concern in Southeast Alaska.”

2019 brought a mixed bag for sport fishermen in Southcentral.

The early run sockeye on the Kenai and Russian River quickly surpassed escapement goals even with the ADF&G increasing bag limits and opening areas usually closed to fishing. At one point, anglers could keep nine daily and have 18 in possession.

“We’ve had other years where we went up to six and 12 daily, but we’ve never had it go up that high. We just had a tremendous return of sockeye, and we use that return to provide opportunities for Alaskans and visitors to our state,” Vincent-Lang said.

Even with additional limit increases for late-run Kenai River and Resurrection Bay sockeye, the 2019 season was tarnished by two major events.

The Swan Lake Fire loomed over of much of the Alaskan summer, and sportfishing didn’t escape the impacts. The Upper Kenai River was temporarily closed for public safety and firefighting efforts during a time period that is one of the most important of the year for trout fishing guides on the Peninsula.
