appreciate the model descriptions. as with all things in nature which end up interacting with you and me, we have no way of determining a confidence interval for results from studies such as these. we have no information regarding the method of angling; time the fish may have been out of the water for a photo; degree of body slim removed during handling/neting; apparent concern by the angler for the fishes well being....... any information coming from these sorts of attempts, while interesting, should be kept at arms length when discussing 'real' mortality. we simply don't know nor will we ever be able to determine what happened to that fish we released. that is why i suggested we all practice the utmost care when we fish and modifiy our tactics to help with this mortality issue. that said, i still could not claim that the last steelhead i released after a quick fight, no blood, no touching, lip hooked, survived. we will just never know.
