It’s a calamity that threatens Washington state’s $270-million-a-year shellfish industry. And it has the Taylors — after a century-plus producing shellfish in the Evergreen State — exploring every potential angle to steel their mollusks against the corrosive effects of ocean acidification.
The researchers then observed the oysters’ physiological responses to ingesting the microplastics. The most obvious effect was on reproduction. Oysters that were exposed to microplastics produced fewer and smaller egg cells and slower sperm. Exposed oysters also produced fewer larvae and their offspring tended to grow more slowly.
Chile’s salmon farmers are using record levels of antibiotics to treat a virulent and pervasive bacteria, driving away some U.S. retailers including Costco Wholesale Corp, which is turning to antibiotic-free Norwegian salmon. The coastal waters of Chile, the world’s second-largest… Read More ›

Fisherman Randy Slavich drags a clunky metal net through an underwater oyster bed in Lake Machias, a brackish body opening into the Gulf of Mexico. For generations, this has been a bountiful lake for harvesting oysters, long before millions of… Read More ›
Studies show that red king crab and tanner crab, two important Alaskan fisheries, grow more slowly and don’t survive as well in more acidic waters. Alaska’s coastal waters are particularly vulnerable to ocean acidification because of cold water that can absorb more carbon dioxide, and unique ocean circulation patterns which bring naturally acidic deep ocean waters to the surface.
