Warren, I agree with you mostly. (Had to quallify that a little) Stocked trout do become more like stream borns if they can survive that long. A difference is the stocked fish are normally hatched from eggs from parents that are
descended from generations of stocked fish and may have lost some of their survival skills. That said, and in opposition to some experts who contend that trout memorys are measured in seconds, I think that their memory is better than that and that stockers do learn. Stockers in delayed harvest streams who get jerked out by the lip a number of times do get harder to catch. Pass the popcorn!
