That’s because salmon body deteriorates fast due to the release of steroid hormones called corticosteroids. Current levels of agricultural and industrial pollution, along with habitat loss and degradation along the main stem of the Salinas and at spawning sites, have made it much harder for steelhead to migrate up the Salinas River.
