Northern Harvest Sea Farms is busy cleaning pens of dead salmon, and the province's head aquaculture vet says higher-than-average water temperatures are to blame.

Along with significant seabird die-offs near Port Heiden, there have been reports of small whales and porpoises, walrus and sea otters washed up on shore.

"It's the first time I guess the whole town seeing a shark in real [life]," he said. "Must have been just about the whole town that come to see it." The shark is likely a salmon shark, typically found around Alaska and B.C.

Returning to port with tons of algae in their trammel nets, with hardly any fish, has become a common drama for the men fishing in Spain's Southern coast. The same “catastrophe” is also threatening the marine biodiversity of the area and piling up on beaches.

Instead of halibut, fisherman are increasingly catching less valuable Pacific cod, voracious bottom feeders whose numbers in recent years have exploded.

The number of chinook salmon that reached the Whitehorse fish ladder this year hit a 40-year low, and it's not clear why. Just 282 chinook passed through the fish ladder this year, compared to 690 last year. "We did see some large pre-spawn mortality die-offs in a tributary of the Yukon River — the Koyukuk in Alaska. This was for summer chum, and not chinook — but we expect that that higher water temperature also affected the chinook migrating through."

A new marine heat wave spreading across a portion of the Pacific Ocean off the coast of British Columbia resembles the infamous "blob" that disrupted marine life five years ago. 

Thousands of smelts were found dead during low tide in the Togiak slough. Is there an environmental cause?

Anglers in Aklavik, N.W.T., are trying to figure out why there was a shortage of fish in local hotspots this year.

The skin lesion in the photo is likely caused by a stress-related bacterial infection – possibly trauma initiated. Probably common opportunistic bacteria in the environment such as motile Pseudomonas/Aeromonas Gram-negative organisms.

Odd time of year for seals to be eating herring.

A considerable number of the herring catch that’s been landed in recent days has been found to be infected. As such, almost all of it will be incinerated. Note, according to Fisheries Information and Resource System (FIRMS) the infection rate of herring with Ichthyophonus in Iceland was estimated to be 32% in the in the winter 2008/2009.

Large egg case found on beach, perhaps belonging to a Big Skate (Raja binoculata)

Sea Star (Pisaster ochraceus) appears sick but is actually healthy.

A meteorologist says unseasonably warm weather in B.C. is once again causing a large area of the Pacific Ocean to heat up considerably, emulating a phenomenon from past years known as the “blob.”

The Tongass Forest in southeast Alaska, a temperate rain forest, is experiencing record-low precipitation and severe drought conditions, impacting community hydroelectricity production.

Ice in the north Bering Sea is diminishing, researchers aboard a Coast Guard ship report.

The counts of fall Chinook at Bonneville Dam are 29 percent below preseason forecasts, and ongoing fisheries are approaching the allowable catch limits under the Endangered Species Act (ESA).

Red tide is officially impacting Pinellas County. Crews have picked up a total of 33.48 tons of dead fish and hauled them off to the county dump.
