Limited Chinook salmon fishing on sections of the Mokelumne, Feather and American rivers is being reopened for the first time in two years, the California Department of Fish and Wildlife announced Tuesday. … The Department of Fish and Wildlife says salmon stocks throughout the state have been harmed by multiyear droughts, causing inadequate spawning and migration conditions, ocean forage shifts and thiamine deficiencies. Thiamine, also called Vitamin B1, is an essential nutrient for salmon and their reproduction. Scientists have theorized that anchovies, which are often prey for salmon, produce the thiaminase enzyme that breaks down thiamine. It’s believed warmer climates have caused anchovy populations to shift to ocean areas where river salmon go to grow and find food before returning to their rivers to spawn.
