ok, this may be a stupid question of sorts...
depending on the year, i fish any where from 30 - 100 days. on a bad day i catch 1-10, on a decent day 11-20. and on the rare occation more than 20.
i try to keep the fish in the water, i try not to handle the body in anyway, mostly i dont like the smell of fish slime - think pike... ick. i have noticed most of my hooks are in the side of the mouth and rarely on the top, my apologize to the white fish i snagged in the tail. i have also picked up the habit of looking at where the eyes are pointing and say i've noticed anything other than down.
usually i can see my fish dart away. i'll fish the same area or move down the river a bit or if i'm on a lake, i dont move around a lot.
i have never noticed that i have 'killed' a fish. i haven't seen on float by tits up on a lake or wash up on the bank of the stream. i tend to fish small streams maybe at most 10 ft across usually less, i'd think i'd notice a lifeless fish.
so how can i tell if i have accidentally killed one, or should i just assume that it croked some time after i left the general area?
ok, i know my pic shows me holding a fish, it was at the request of the guide i was with... he came up, pic taken and went back. all the time i was concerned about how long he was out of the water... seconds at most. then we put him in the net, back in to the current for a min and then let him go. he also shot back out to the middle of the river
