Study: Warmer water makes for smaller juvenile salmon

Juvenile chinook salmon: warm water means smaller fishA new analysis of juvenile Chinook salmon in the Pacific Ocean documents a dramatic difference in their foraging habits and overall health between years of warm water and those when the water is colder.

The study found that when the water is warmer than average – by only two degrees Celsius – young salmon consume 30 percent more food than during cold-water regimes. Yet they are smaller and skinnier during those warm-water years, likely because they have to work harder to secure food and the prey they consume has less caloric energy.

Results of the research, conducted by researchers from Oregon State University and the National Oceanic and Atmospheric Administration, are being published this week in the journal PLOS One.

“When young salmon come out to sea and the water is warm, they need more food to keep their metabolic rate up, yet there is less available food and they have to work harder,” said Elizabeth Daly, an Oregon State senior faculty research assistant with the Cooperative Institute for Marine Resources Studies, a joint program of OSU and NOAA.

OSG announces 2016-18 funded research

Posted on by

Oregon Sea Grant will support eight research projects by scientists at three Oregon institutions during 2016-18, on topics ranging from sea-level rise to invasive jellyfish. The grants are funded by the National Oceanic and Atmospheric Administration as part of a biennial appropriation from Congress to Sea Grant programs around the country.

The grants will go to eight principal investigators at OSU, Oregon Health & Science University, and the University of Oregon for research into ocean and coastal issues.

“Oregon Sea Grant is committed to supporting the science needed to address challenges facing our coastal communities and ecosystems,” said Sea Grant director Shelby Walker. “These projects reflect a broad array of issues important to the future of coastal Oregonians, communities and our environment.”
