Wild vs. hatchery trout
Question: How can you tell a hatchery trout from a wild trout in Central Valley rivers? The regulations for the Stanislaus River below Goodwin Dam state you can keep two hatchery trout or hatchery steelhead. Hatchery steelhead have clipped adipose fins. If I catch a trout and it has an adipose fin, do I just assume it’s not a hatchery trout?
