They're released with out fanfare. But when they catch a big bass, out comes the net, then long admiring glances, photos, and perhaps a ride in the livewell.
"From a conservation standpoint, big fish are extremely valuable. They're the best spawners and the ones we should be releasing. Unfortunately, big bass are most damaged by catch and release. They're battled longer and held out of water longer. This contributes to a greater physiological disturbance.

Getting back to the original subject, I agree 100% with everything that is stated above. I am positively convinced that "big mature fish" are the prime spawning stock and a fundamental key to the healthy survival of the species.
To put in in perspective I agree the 20-30" year classes need absolute protection. (Bear with me - I'm a walleye snob at heart and these sizes are based on the Sask River (they're the only firm numbers I know) - for BOQ/Erie they probably could/should be slid to the right by a couple inches). What has also been shown is that after the 30" mark - those year classes are no longer as prolific spawners. They tend to die of natural causes; and those that survived seemed to care less about spawning. At this stage (again - I'm not talking "mature" adult fish, I'm talking old mossy backed leviathans) they could be removed with minimal impact, anbd the economic benefits of becoming known as a trophy walleye factory - with a chance to "take home" a fish of a lifetime outweigh their usefulness in the population.
I agree 100% that mature adults need protection - absolute protection in my opinion. I don't know what sizes we're talking about exactly certainly as a minimum the 20-30" bracket, probably higher for big water fish in the Great Lakes. In numerous previous posts I've questioned the minimum size rules currently used in Ontario to encourage population growth - suggesting that instead it's the more mature fish which are unprotected under the current rules which most need protection. I would argue that unless you are willing to accept permanent put-and-take style stocking programs the populations will never recover when the potential prime spawning stock is removed every year as they hit the 16 or 20 inch mark.
And for the record, I'm 100% C&R with big walleye. That's my personal choice. Others can do what they want within the law and that's fine.
There are few problems in life which can not be solved with a well-placed, high-explosive projectile.
