I was not attacking you on how you fish or what you keep.  I was just curious if you knew of a study that show survival rates. Not the day of the fizzing but days after.

i talked to a biologist many years ago on deep water lakers and his feeling was we lost about 10% and those fish were coming from a 100 ft. plus trolling , and thanks for the read it would be nice to see if something more up to date was at hand , if i get a chance i know the new head bioloigst hear and get his take on this maybe there is something new for info , didn't mean to sound gruff sorry

The sask anglers guide quotes the same data - 10% mortality on C&R.

Thats on catch and release.  Not from fizzing.  If its 10% when c and r is done correctly fizzing has to be worse then that.  The study has some numbers around a 50% death rate.

would like to see that data thanks

When it comes to the subject of c+r in deep water there is a lot more to consider than the swim bladder and the abbility to swim away.these fish subjected to the bends,the same as in humans.with the injection of air into the blood stream it affects all of the organs such as liver,gills,brain,etc.Allof the studies Ihave read,they are done in controled conditions such as holding tank,extra oxygen,weights on the fins etc and released to swim away,but not moniterd to see if they actualy survive.Areal life study would be get out in the boat or on the ice,catch these fish in 30+ fow in a normal matter ,and then radio tag and monitor for a week or two.then and only then can we truly get some mortality rates...maybe some of our fish and game organizations could sponsor something like this??    Just something to think about while we sit on our pails in those SLACK TIMES.....Enough rambling on my part. any thoughts???

my estimate on fish pulled from deep would also be around 40-50%. I do believe that bringing them up slowly does make a difference.  We used to catch big walleyes cranking on LML in 25-30 feet and we would reel them in slowly and they had no problems going down-they were nice and healthy when we released them.  But cranking a fish straight up from 30 ft when ice-fishing seems to have a really negative effect-their eyes bulge from their heads and their bladders are right full.  Different technique with different results. Regardless, try to catch fish in shallower water if possible.

well guys i found more crap on this subject some biologist in favor said death rates were lowered and some said just the oposite , so i'm with WP need to be tagged and monitored ,later    tite lines guys
