The survey started in 1971 as a review of commercially important fish like cod and halibut, but has grown into an annual scientific assessment of all sea life hauled up from the deep.

A new study has documented unexpected consequences following the decline of great white sharks from an area off South Africa. The study found that the disappearance of great whites has led to the emergence of sevengill sharks, a top predator from a different habitat. A living fossil, sevengill sharks closely resemble relatives from the Jurassic period, unique for having seven gills instead of the typical five in most other sharks.

Fifty percent of Saimaa ringed seal pups born between the years of 2014-2017 entered the world in a snowdrift constructed by volunteers.

Thriving communities of red algae are doing something nefarious to the world's ice sheets: melting them more quickly.

Scientists say the threat from sargassum is as serious as rising sea levels and hurricanes.

Like a horde of slimy green zombies, the incredibly invasive American bullfrog is hopping the border into the West Kootenay.

Guyana’s fish production has suffered a significant decline partly due to the adverse impact of sargassum seaweed, local and regional fishery experts said.

B.C salmon farms last year were besieged by sea lice, according to a new University of Toronto study, which also found a dangerously steep rise of infestation among young wild salmon who swam nearby.

July 23, 2007 – Over the last five years, large, predatory Humboldt squid have moved north from equatorial waters and invaded the sea off Central California, where they may be decimating populations of Pacific hake, an important commercial fish.

Seals are typically resilient and adaptable to their environment, but a new study found that rapid warming in the past decade is causing a rampant physical decline in seals and their pups.

Experts use measuring sticks and tanks in regular intervals to monitor snowfall as this season’s total approaches an all-time high.

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.

“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.

Researchers at Oregon State University are studying the relationship between sunflower sea stars and sea urchins to determine if the reintroduction of the sea stars can help protect declining kelp forests from overgrazing by sea urchins.

Unusually high numbers of the chunky little finches in Southcentral are prompting surprising questions from bird lovers.
