Do you think that holdovers are stressed to begin with and that catching and releasing them results in a lower survival rate?

holdover bass??

or trout?

either way in cold water with high oxygen u have little to worry about

The survival rate on lure caught striped bass at temps below 60 degrees is near 100%.

It is catch and release in warm water (above 70 I think) that does the vast amount of damage. Then again at least 50-70 % of those fish do better than those sold for food.

Doesn't success rate have a lot have to do with technique and experience? Unhook and throw back with or without caring to revive......

Anderson /has had a great return rate for the thousands he,s tagged in the Thames ;;;

No, it has most to do with water temp.

After that hook location. As I understand it, lures with trebles, that usually end up in hard tissue do some mutilating but less death than bait which often ends up in soft tissue. Trebles with bait are the worst. That's why meat fisherman prefer them. Then J hooks, then circles.

The real bass killer for recreational C&R fishermen is time out of water in warm weather. Even with a very short time out of water many released fish die when water temps are high. I think the larger the fish the worse it gets (but have not seen that actually studied).
Still, in the studies that have been done, under the worst conditions more than 1/2 the released fish survive (even with soft tissue injury).

As for handling stress, there is a lot of inconsistency. Supporting snook by the jaw apparently injures many (isthmus injury), but the same treatment of LMB and very large muskies seems well tolerated. Nets in general add to mortality a bit.

The above is my understanding of this issue. I'm not somewhere I can provide links, but I have looked into it several times.

we always use a wet towel when touching any fish , if its going to be kept we IKE them , if not then a gentle slide back in to water to release them . Never used a treble , in fact normally we file the barbs off the single hooks , that way you only have to keep the weight on the fish , once the weight comes off the fish falls in the boat

Here is a link with some data Catch and Release Fishing Mortality Study (http://www.acuteangling.com/Reference/C&RMortality.html)

Here is a study (FW Striped Bass) that mentions temp effects. There is a better one somewhere that I can't find.
