MAINE: Final Penobscot salmon estimate for last year drops by nearly 200 fish

January 7, 2021 — The Maine Department of Marine Resources has reduced its estimate of Atlantic salmon returns to the Penobscot River by nearly 200 fish, but the final estimate for 2020 — 1,440 salmon — is still the highest annual return since 2011. In November, state fisheries scientists announced an estimated 1,603 Atlantic salmon had returned to the Penobscot River.

Jason Valliere, a marine resource scientist for the DMR, said each of his regular reports filed since July have included a disclaimer explaining that the official year-end estimate of returning fish was subject to change. Those counts are adjusted after data becomes available, taking into account individual fish that are captured, returned to the river to free-swim to spawning grounds, then re-captured by fisheries staffers at the Milford Dam.

The 2020 total was up from 1,152 in 2019, and is the largest run of salmon since 3,125 salmon returned to the river in 2011. The average run for the eight years from 2012 to 2019 was just 708 salmon per year.

New research signifies “an important step forward in aquaculture genomics”

November 20, 2020 — New research highlights the possibilities that genetic variation in Atlantic salmon offers for advancing aquaculture production.

Spearheaded by Alicia Bertolotti, the new research involved sequencing the genomes of 492 Atlantic salmon in a project led by professor Dan Macqueen at the Roslin Institute (University of Edinburgh) in partnership with Xelect, the University of Aberdeen, and many international collaborators – including the Norwegian University of Life Sciences.

AquaBounty announces Kentucky as next planned GE salmon farm site

October 30, 2020 — AquaBounty Technologies announced that Mayfield, Kentucky, U.S.A., has been selected as its favored site for a future 10,000 metric ton (MT) land-based salmon farm.

The new farm would be the first large-scale commercial facility for the company’s AquAdvantage salmon – a proprietary genetically engineered Atlantic salmon. The new location would be eight times the size of the company’s existing farm in Albany, Indiana, which currently has a production capacity of 1,200 MT.

WASHINGTON: Local salmon project gets boost from Cooke Aquaculture fine

August 7, 2020 — A plan to offer recreation opportunities and improve salmon habitat where a bend in the Skagit River hugs Marblemount is getting a boost in funding.

The $265,600 being given to the nonprofit Skagit Fisheries Enhancement Group comes from a penalty levied against Cooke Aquaculture for a 2017 incident in which a company net pen broke, allowing Atlantic salmon to get into the Salish Sea.

The money will allow for completion of Pressentin Park, which has been in the works for several years in coordination with Skagit County Parks and Recreation.

“This is a really high-priority project we have been working on for a long time to support native juvenile chinook,” Skagit Fisheries Executive Director Alison Studley said.

MAINE: This Atlantic salmon has returned to the Penobscot more than once. Here’s why it’s special.

June 4, 2020 — Atlantic salmon are returning to the Penobscot River at a steady pace thus far. Fisheries staffers from the Maine Department of Marine Resources said the 176 salmon that have been counted thus far are the fifth most to have reached the counting facility by May 29 in the 42 years that salmon have been counted on the river.

Among those fish was a rarity: A male that was making a return trip to the river to spawn.

Jason Valliere, a fisheries resource scientist for the DMR’s Division of Sea Run Fisheries and Habitat, said not many salmon are able to head to the open ocean twice and return to the Penobscot successfully, and called the fish “extra special.”

“We previously captured this fish on June 10, 2018, when we tagged him and sent him to Craig Brook National Fish Hatchery [in Orland] as a brood fish to support the smolt stocking program, a program that he is a member of. He was stocked out as a smolt in 2016,” Valliere said.

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.

Global salmon production set to rise 6.5% in 2019, the highest increase since 2014

December 6, 2019 — Global production of farmed Atlantic salmon is expected to rise by around 6.5% this year, to approximately 2.6 million metric tons, which would be the highest year-on-year increase since 2014.

This was pointed out by a new report produced by the Food and Agriculture Organization (FAO) of the United Nations. The bullish scenario could be offset, however, by a mounting challenge with sea lice in Chile, the report predicted.

For 2020, the FAO foresees Atlantic salmon supply to grow around 4–5% year-on-year, but it noted that the ability of the Chilean industry to bring the biological situation under control will be an important consideration.

In the longer-term, the inherent growth limitations of traditional open net-pen aquaculture will continue to drive the development of alternative regions and methods for salmon production, the FAO said.

MAINE: Nearly 1,200 Atlantic salmon returned to Penobscot this year

November 21, 2019 — When fish lifts in Milford and Orono closed for the season Nov. 13, the Maine Department of Marine Resources reported that a tentative total of 1,196 Atlantic salmon had been counted at those facilities this year — the largest number counted in eight years.

Jason Valliere, a marine resource scientist for the DMR’s Division of Sea Run Fisheries and Habitat, said that 1,152 salmon were captured at Milford and 44 were captured in Orono. The trap counts do not reflect the exact total of fish that returned to the river, he said, because some simply did not move into the fish lifts and avoided capture.

“Please note this is the estimated trap return to the Penobscot and not the final estimated return to the river,” Valliere said. “[Salmon] redd count data will be added this winter and the final estimate will be reported in the 2020 U.S. Salmon Assessment Committee Report.”

That report will be released early in 2020.

Salmon redds are depressions in the river bottom made by female salmon during the egg-laying process and serve as further evidence of actual spawning salmon.

US launches investigation into Mowi price-fixing allegations

November 14, 2019 — Salmon farming giant Mowi has announced it is being investigated by the U.S. Department of Justice regarding allegations of price-fixing in Norway’s farmed Atlantic salmon market.

The move by the U.S. DOJ stems from an ongoing investigation by the European Commission into “concerns that the inspected companies may have violated E.U. antitrust rules that prohibit cartels and restrictive business practices.” That investigation became public in February, when the E.C. carried out unannounced inspections at the premises of several Norwegian firms involved in the farmed Atlantic salmon sector in Europe.
