Warmer Arctic waters produce more pink salmon, study finds

 

 

Global warming could prove to be favourable to pink salmon producers, as a new study has found that the warming weather is conducive to the production of more pink salmon in Arctic rivers and streams.

 

The Associated Press reports that the study's findings bolster Alaskan subsistence fishermen's account of catching more pink salmon, with the Arctic warming at more than double the rate of the rest of the world.

 

"Maybe in the past, they'd see a few adult pink salmon here and there every few years. Now they're seeing them every year", Ed Farley, a federal fisheries scientist at the Auke Bay Laboratories in Juneau, was quoted as saying in the AP report.

 

The scientists found that young pink salmon fare better in warmer temperatures, in turn increasing the likelihood of larger numbers of adult fish spawning the following summer.

 

"It's likely in the future we could see successful spawning", Farley said. "When that happens, you're going to see more pink salmon in the High Arctic".

 

Meanwhile, according to the AP, some Arctic residents are targeting the increasing numbers of pink salmon by changing their fishing techniques.

 

For one, Sheldon Brower, from the village of Kaktovik on Alaska's North Slope, said that he plans to use a net with a larger mesh, hoping to snag more pink salmon.
