"Climate Change Drives Salmon Evolution"

"For salmon trying to make it upriver to spawn before a hot summer hits, slow and steady loses the evolutionary race. Salmon DNA records stretching back over 30 years show that nature has increasingly selected for fish that migrate from the ocean earlier in the year. It is among the first pieces of genetic evidence that climate change is driving the evolution of a species."

"Taking Shark Fin Soup Off the Menu"

"Humane Society International called it a 'monumental decision' and a 'watershed moment for the global movement to protect sharks.' The conservation group Shark Savers said it 'could be the best news for the oceans in some time.' The major development? The Chinese government announced Tuesday that it would ban the serving of shark fin soup, a prized and expensive delicacy, at official banquets."

"Sea Sick: Another Virus Crashes Canada’s Salmon Farms"

"Last month a virus broke out in several open water salmon farms in British Columbia that has the region’s fish farm owners scrambling to mitigate their losses."

"Called infectious hematopoietic necrosis (IHN), the rabies-like virus was found among salmon in floating net pens belonging to Mainstream Canada, the biggest producer in the region. As a result, B.C. farms culled over 500,000 fish infected with IHN, which spreads rapidly and can kill up to 100 percent of a fish farm’s population. And it’s just the latest disease scandal to hit the province’s salmon farming industry.

"Fishing Discards Practice Thrown Overboard By EU"

"The wasteful practice of throwing away healthy and edible fish at sea will be ended in Europe, for the first time in four decades, in a partial victory for environmental campaigners who have viewed a discards ban as the key step to preserving fish stocks. But -- crucially -- the date when such a ban will come into force is still in question, raising fears that it may be implemented too late to save some species."

"Weather Center: 50 Percent Chance of El Nino Later This Year"

"There is a 50 percent chance the feared El Nino weather pattern which can trigger droughts in Southeast Asia and Australia and floods in South America may strike later this year, the U.S. Climate Prediction Center warned on Thursday."

"In its strongest prediction so far that El Nino could emerge, the CPC said conditions are still expected to be neutral between June and August, but there is a 50 percent likelihood that El Nino will develop in the remainder of the year.
