Trucking Is Mucking Up Chinook Salmon Diversity

Approximately half of the roughly 32 million juvenile fall-run Chinook produced by Central Valley hatcheries each year are trucked and released directly into the San Francisco estuary. When fish are trucked for most of their juvenile migration, they fail to imprint on their home river, which can increase straying rates of returning adults by up to 80%.
