Battered by a marine heatwave, Kodiak’s cod fishermen may not be fishing in the Gulf for much longer
From the last peak in 2014, the level of mature, spawning cod crashed by more than half in the Gulf, according to stock assessment data — 113,830 metric tons in 2014 to 46,080 metric tons in 2017. They’re now below the federal threshold that protects cod as a food source for endangered Stellar sea lions. As soon as the population dips below that line, the fishery closes. The whole federal cod fishery in the Gulf will most likely be shut down for the season in January. >click to read< 10:36
Oregon researchers investigate latest marine heatwave that could hurt Pacific ecosystems
Earlier this month, the feds announced there was trouble brewing in the Pacific: a mass of warm water was building off the west coast, reminiscent of another event nicknamed “The Blob,” which caused havoc for wildlife and fishermen just a few years ago. Experts caution that the current marine heatwave is still in its infancy and could dissipate today, tomorrow or next week.,,, “This marine heatwave took shape in June, persisted, and has grown in size,” said Chris Harvey, a research biologist at the Northwest Fishery Science Center, >click to read< 17:54
The Legacy of the Blob
In 2013, a mass of unusually warm water appeared in the Gulf of Alaska. Over the next three years, the Blob, as it became known, spread more than 3,200 kilometers, reaching down to Mexico. This freak marine heatwave, combined with a strong El Niño, drastically affected the Pacific Ocean ecosystem killing thousands of animals and changing the distribution of species along the coast. It’s been three years since the Blob dissipated, and researchers are taking stock of its long-term impacts on fish and other wildlife. >click to read< 08:41
WA’s scallop quota doubled after stock recovery
The quota for WA’s commercial scallop fishery has almost doubled this season, due to a recovery of stocks after a marine heatwave in 2010/11. Fishermen will be able to take 330 tonnes in 2017, compared to 166 tonnes last season. Department of Fisheries principal scientist Mervi Kangas said the speed of recovery in the Shark Bay fishery had quickened.”The stocks are recovering. Denham Sound, which was the key area where most of the scallop take came from, has actually recovered,” Ms Kangas said. “The northern part of Shark Bay is still recovering, but it is improving each year.” continue reading the story here 19:57
Poor Ocean Conditions Hit West Coast Fisheries Hard
United States commercial fisheries are doing fine overall, but fishermen on the West Coast are hurting. An 2015 annual report out Wednesday from the National Oceanic and Atmospheric Administration shows a stark fall-off in the big seafood money-makers in the Pacific Northwest. Nationally, 2015 was an above average year in terms of catch rate, commercial value and national seafood consumption. “On dinner plates, the average American added nearly an extra pound of seafood,” said Richard Merrick, Chief Scientists of NOAA Fisheries during a call with reporters. But this rise in consumption didn’t really help the Oregon and Washington fishing industry because the crab and fish weren’t there to catch. NOAA Fisheries scientists are attributing the low West Coast returns to abnormal conditions in the Pacific that are linked to climate change. Read the story here 19:11
