Stocker Survival

STOCKER SURVIVAL: That stream-bred brown trout are occasionally caught in the upper Wood River watershed indicates that at least some stockers live long enough to spawn in the Fall. Sampling done in other states verifies stocker survival. Maine has documented that stocked brook trout can survive more than two years; in Michigan browns made it past age four; and Connecticut notes that yearling trout planted in the Spring “regularly comprise a significant number of remaining trout in late Summer.” As regards the direct and indirect impacts of stockers on wild fish, those farmed fish do not have to last more than the alleged “two weeks” if the water is being stocked every week as sometimes happens on the upper Wood River.
