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."

Inside the Industry

NMFS has awarded 16 grants totaling more than $2.5 million as part of its Bycatch Reduction Engineering Program.

The program supports the development of technological solutions and changes in fishing practices designed to minimize bycatch and aims to to find creative approaches and strategies for reducing bycatch, seabird interactions, and post-release mortality in federally managed fisheries.


Abe Williams, who was elected to the Bristol Bay Regional Seafood Development Association board last spring, has been selected as the new president as of September.

Williams fishes the F/V Crimson Fury, and is president of Nuna Resources, a nonprofit that supports sustainable resource development in rural Alaska, including fighting for an international solution to issues raised by the proposed Pebble Mine project.
