That matters, the experts said, because growing quickly can be the difference between life and death for vulnerable juvenile salmon. “Previous studies have shown that to survive to adulthood, young salmon need to get big fast,” said Sean Godwin, a PhD student at SFU and lead author on the study. “Those that grow more slowly — as we found, those heavily infected with sea lice — those fish are more likely to die.” Many people opposed to fish farms have raised concern over declining wild Fraser River sockeye and the potential for parasite transfer from salmon farms. click here to read the story 10:23

New Study Finds Fishermen’s Expertise is Rarely Considered by Scientists

paul vitale 2012The study, published this week as Editor’s Choice by the ICES Journal of Marine Science shows that if scientists from Canada to Kiribati had worked more closely with fishermen over the last 100 years they could well have prevented infamous events like crashes in regional cod populations, as well as some of the rapid degradation we are currently seeing in tropical coral reef environments.

Salmon can adapt to warmer environment, study says

863a4ac9dc_64635696_o2With climate change heating up British Columbia’s rivers, there are growing concerns about the vulnerability of cold-water species such as salmon. But a shows salmon may have the ability to adapt to a warming world because Chinook that lay larger eggs produce offspring that have greater heat tolerance. Read more here 10:39

More Salmon May Survive The Ocean Than Previously Thought

When Columbia River salmon reach the ocean, they may swim off in different directions than previously thought. that could require new thinking on how many fish are surviving their journey to the sea. [email protected] 13:48
