New Study Shows Pacific Cod Eggs are Highly Vulnerable to Changes in Bottom Temperature

New Study Shows Pacific Cod Eggs are Highly Vulnerable to Changes in Bottom Temperature

  The 2013 to 2016 marine heatwave—known as “The Blob”—is the largest warm anomaly ever recorded in the North Pacific. In the Gulf of Alaska, scientists have connected low numbers of Pacific cod larvae, juveniles, and adults to loss of spawning habitat. This occured during and immediately following the heatwave. Compounding the ecological loss is the […]

Sockeye Carcasses Tossed on Shore over Two Decades Spur Tree Growth

Hansen Creek, a small stream in southwest Alaska, is hard to pick out on a map. It’s just over a mile long and about 4 inches deep. Crossing from one bank to the other takes about five big steps. Yet this stream is home to one of the most dense sockeye salmon runs in Alaska’s […]

New Information on How Long some Rockfish Live and How Often they Spawn

New Information on How Long some Rockfish Live and How Often they Spawn

Some things just get better with age. Like rockfish mothers. A rockfish might not start spawning until she is 25 years old. As she gets older she produces more, and more robust, young. She continues to produce them over many years, into advanced age – which for some rockfish means 100 or 200 years. That […]

Delayed Effects of Oil Spill Compromise Long-Term Fish Survival

By NOAA Fisheries on Sep 10, 2015   Featured, Science/Education  

Delayed Effects of Oil Spill Compromise Long-Term Fish Survival

For 25 years, methodical research by scientists has investigated the effects of the Exxon Valdez oil spill in 1989 on Alaskan communities and ecosystems. A new study released today into the effects of the 1989 Exxon Valdez oil spill in Alaska shows that embryonic salmon and herring exposed to very low levels of crude oil […]
