Dismal returns for chinook salmon on B.C.’s Fraser River reveal latest threat to endangered orcas
A test fishery for chinook salmon on the Fraser River this year is reporting dismal returns, raising new concerns for the endangered southern resident killer whales who rely heavily on these fish for their survival. The federal government announced in May a reduction in harvest of chinook by roughly one-third and closures in some key whale foraging areas after declaring the southern resident killer whales are facing an imminent threat to their survival. The federal government acknowledges that lack of prey is one of the critical factors affecting the whales’ recovery. >click to read<20:36
Endangered orcas compete with seals, sea lions for salmon
Harbor seals, sea lions and some fish-eating killer whales have been rebounding along the Northeast Pacific Ocean in recent decades. But that boom has come with a trade-off: They’re devouring more of the salmon prized by a unique but fragile population of endangered orcas. Competition with other marine mammals for the same food may be a bigger problem than fishing, at least in recent years, for southern resident killer whales that spend time in Washington state’s Puget Sound, a new study suggests. click here to read the story 07:43
Navy to Expand Sonar, Other Training off Northwest Coast
The U.S. Navy has finalized a plan to expand sonar testing and other warfare training off the coasts of Washington, Oregon and northern California. The Navy decided to implement its preferred plan after a lengthy review that included a determination from the National Marine Fisheries Service that the exercises would not have major impacts on endangered orcas and other marine mammals. It announced its decision on Nov. 4. The fisheries service last year renewed the Navy’s five-year permit, through 2020, to conduct the activities in areas from the inland waters of Puget Sound in Washington state to the northern coast of California. The plan includes expanding the use of “sonobuoys,” devices that send out underwater sonar signals used by air crews training to detect submarines. Read the rest here 16:54
