A lesson learned. The first year we were trapping a stream we got a dime-bright fish that had not many spots and no color but silver. ID'd it as a steelhead jack. Fortunately, we tagged it. Came downstream as a SRCT female kelt. We saw her a few more years; she even spent the summer in a local lake. After that first return she was dark colored. Don't think we ever got any others that were that bright.
