I recently had a discussion about hatchery grown salmon and was told that not every fish released were fin clipped; only about one out of ten. Does anyone know this for sure?

osmosis said:That "adipose intact" fish is a mid sandy basin spawning TULE and they have not planted tule in that river to interfere with that gene pool. sure some may have strayed since fish are good at wandering - but that fish is about as close to "wild" as we have left in an over fished hatchery dominant river..
