Data cited by the B.C. Centre for Disease Control suggests 75 per cent of wild Pacific salmon are infected with the parasite. If fish is to be consumed uncooked, killing the parasites requires it to be frozen at -20 C for at least a week, Young said. Most commercial sushi-grade seafood suppliers freeze at -40 C.

Scientists looking at salmon found in Arctic waters are still asking northern harvesters and fishers to submit any unusual catches in exchange for compensation. It's part of the Arctic Salmon Project, which is a collaborative effort involving Fisheries and Oceans Canada, scientists from the South and local hunters and trappers organizations.

An executive order issued by President Biden extends the ban on Russian seafood imports to include products processed in other countries, closing a loophole from previous sanctions.

Fish traps have a long history around the world, and a vast network in a Vancouver Island estuary reveals generations of ecological wisdom.

“Our results suggest that warming is both increasing freshwater habitat and improving early marine survival of pink salmon in the northern Bering Sea,” said Ed Farley, NOAA Fisheries biologist at the Alaska Fisheries Science Center, who led the study.

Pacific pink salmon (Oncorhynchus gorbuscha) were introduced in the Kola Peninsula for their valuable eggs in the 1950s. Since then, the species has spread along the entire Norwegian coast and will probably remain. This sudden increase in pink salmon numbers in Norway, thought to be linked to favourable climate conditions for pink salmon reproduction and survival, is expected to continue as water temperatures rise with climate change and large numbers of fish continue to arrive from Russia.

Rising temperatures and dwindling oxygen levels are decimating marine species. But humanity can avert mass die-offs by curbing fossil fuel use and other planet-warming activities.

Similar projects have proven successful in Germany and other Baltic countries. ”And finally it's Sweden's turn” says project manager Linnéa Jägrud..

The lights require no plugs or batteries, automatically turn on underwater only when needed, and do not weaken or weigh down nets.

“Dramatic”, says researcher Henrik H. Berntsen. The Norwegian Environment Agency has launched a major offensive to get rid of the invasive species. But, despite more fishing, there appear to be ever more humpback salmon arriving in Norwegian rivers. Currently, around 70,000 pink salmon have been caught in Norwegian watercourses this year.

Between 2017 and 2019, pollock surveys in the Gulf of Alaska produced wildly different estimates. A new study shows what climate-driven mismatch in pollock surveys for sustainable fisheries management.

Widespread mortality of Pacific salmon Oncorhynchus spp. returning to spawn in Alaska coincided with record-breaking air temperatures and prolonged drought in summer 2019.

First Nations in British Columbia are using AI technology to accurately count and differentiate species of wild salmon in order to inform harvesting practices and aid in conservation efforts.

Salmon runs in Alaska's Kuskokwim River show some improvement compared to last year, but overall numbers remain low, with chum and coho salmon still below long-term averages, while Chinook salmon meet escapement goals through precautionary management and sacrifices by subsistence users.

Due to anticipated continued increased temperatures, Finland's inland fishing problems are likely to continue.

Bristol Bay’s 2021 sockeye run is the largest on record: 63.2 million fish have returned to the bay, breaking the 2018 record of 62.9 million.

Federal regulators have approved a plan to demolish four Klamath River dams, a historic act that is intended to save imperiled salmon. “The Klamath salmon are coming home,” Yurok Tribe Chairman Joseph James said in a statement. “The people have earned this victory and with it, we carry on our sacred duty to the fish that have sustained our people since the beginning of time.”

Bristol Bay’s prolific salmon runs are also made possible because of the effective and transparent management of the Alaskan salmon fishery, according to both Hill and Schindler. Decisions are made in real time, on the ground — or, to be precise, overlooking the water — compared to the much more cumbersome and bureaucratic Canadian system.

Two resolutions brought before the Alaska Federation of Natives during this year’s annual convention called for efforts to reduce salmon bycatch for fish that return to the Yukon and Kuskokwim rivers.

While the Centers for Disease Control and Prevention recently reported larva of Japanese broad tapeworm has been detected in wild pink salmon from Alaska, the Alaska Dept. of Fish and Game says the discovery is nothing new.
