Researchers are studying precociously mature dwarf males for ways to selectively breed farmed salmon that better withstand higher ocean temperatures.
Warmer ocean temperatures resulting from climate change may lead to earlier sexual maturation in salmon – which could spell problems for the aquaculture industry. Now, the Institute of Marine Research is applying knowledge about the salmon genome in experiments to influence the onset of puberty in farmed salmon through selective breeding.
The project, called Salmat, receives funding from the Research Council of Norway as part the research effort targeted towards understanding climate change and the adaptations it requires.
"The project's objective is to identify genes or regions of genetic material that regulate the onset age of sexual maturation in salmon," explains project manager Anna Wargelius, who is a senior scientist at the Institute of Marine Research. "Since puberty is also modulated by environmental factors such as light, temperature and food supply, the project will study whether and how environmental factors affect the genes that control sexual maturation."

The Alaska Seafood Marketing Institute is still seeking public review and comment on the Alaska Responsible Fisheries Management Conformance Criteria (Version 1.2, September 2011). The public review and comment period, which opened on Dec. 3, 2014, runs through Monday, Feb. 3.
NOAA, in consultation with the Department of the Interior, has appointed 10 new members to the Marine Protected Areas Federal Advisory Committee. The 20-member committee is composed of individuals with diverse backgrounds and experience who advise the departments of commerce and the interior on ways to strengthen and connect the nation's MPA programs. The new members join the 10 continuing members appointed in 2012.
