The parasite Kudoa is causing trouble for the fishing industry in the southern hemisphere. By chance, researchers found the scary parasite in coastal cod from the Helgeland coast.

This crab from the Pacific Ocean was once introduced into the Barents waters of the Soviet Union in Arctic Russia. Since then the invasive species has spread to Norway’s Barents Sea and a multi-million dollar industry has sprung up around it. In 2023 Norway exported 2,500 tons of king crab worth 1,2 billion kroner (€100 million).

However, numerous fishermen say the assessment of a decline in the stock doesn't match what they're seeing on the water, where haddock appear to them to be plentiful.

Elodea was first observed in Harding Lake in 2020 growing in isolated patches and has since been assessed and managed by the Fairbanks Soil and Water Conservation District and its partners.

It’s only the second time in history that the ocean salmon fishery has been closed in California, and the decision reflects a major decline in fish populations after the state’s driest three-year period on record.

Off to a very slow start.

Historically cold temperatures made it difficult for invasive species survive in Alaska. The Japanese skeleton shrimp Caprella mutica is now established in Unalaska area and in this observation observed on a buoy line in Nateekin Bay.

Observations this year from Huu-ay-aht territory see that volume of herring may finally be improving, as the First Nation is reporting a growing number of wild salmon migrating through its rivers.

Increasing blanket of mucus-like substance in water threatens coral and fishing industry

A tumor is present on the lower jaw of the sheefish (Stenodus leucichthys).

State officials estimate that 16.8 million fish will have to be trucked from the four state-run hatcheries through the beginning of June, about 20% more than in a normal year. Hatchery managers were able to release the majority of their juveniles upriver before they deemed river conditions too dicey to proceed.

A major drought has forced farmers and Indigenous tribes to compete for water in a situation nobody ever wanted.

Thousands of euphausiid shrimp, the species identified here in Resurrection Bay as Thysanoessa spinifera. were washed into the intertidal zone and on the beach near Whittier

The size of king salmon returning to Western Alaska rivers to spawn has been decreasing over the past few decades. Researchers at the University of Alaska

The carcasses of four gray whales have been found around the San Francisco Bay Area in eight days -- an alarming string of deaths that constitutes an unusual mortality event, defined by the National Oceanic and Atmospheric Administration (NOAA) as a significant die-off of a marine species.

Sediment that could fill the volume of 112 Olympic-sized pools has been flooding into the Kalamazoo River for over a year. IT's decimating habitats and causing a serious potential for devastating flooding.

Ponderosa pines in Eastern Washington are displaying signs of irregular growth.

"We’re way, well below what we expect to be at this point,” said Jeremy Botz, a biologist with the Alaska Department of Fish and Game. He says so far the entire commercial fleet has harvested around 6,000 sockeye, which is way below what the department anticipated

The Baldwin Peninsula near Kotzebue has seen a massive increase in beavers over the last two decades, according to new research from the University of Alaska Fairbanks.

A large stock of capelins have been found in Faroese fjords of late and scientists believe that the fish probably swam there from Icelandic waters, RÚV reports. Iceland’s capelin stock has been in decline over the last two years, likely due to rising ocean temperatures.
