I would think that time out of water is the biggest culprit, followed by a gut hook while fishing bait, then hook in the gills. I'm curious what others think.
The studies have shown that the single biggest factor affecting release mortality is the water & air temperatures. With high temps, almost 100% of the released fish die.

What would be considered "high temperatures"? August 75 degree water?
That would be crazy to think that all the fish we catch and release in the month of august arent making it.
I wonder how we could ever know. I almost wish there was a way to use a transponder tagging system to see if a released fish lives or dies.

I did a quick look see at what the average August temps are in estuaries from the Chessie to Cape cod and found that the water temps in August are basically the same from the Chessie to LI sound. North of LI sound the temps were lower. The studies I was referring to were done in the Chessie.

Here is something that I just thought about...

What is the mortality rate of Largemouth bass? It is common practice to keep these guys in a small live well on a boat that is getting banged around for
hours during a tournament, Brough to scales in a bag of water, and then carried around hoisted like luggage in the air while shouting and running...
Who knows when they get released... and it is always assumed that they all survive. Do they? do most live? do many die?
do more largemouth bass die than we think? or do they mostly live?

If most largemouth bass live, is it possible the 10% striped bass mortality rate inaccurately high?
Just wondering if there is a correlation.

just having this discussion is an improvement from what we all were doing in years gone by.... being AWARE of how we handle fish is the first and biggest step we can take towards improving release mortality

Having done it for four years I can say for certain there is a much higher death rate in the summer and many fish don’t even survive to get released and those dead fish cost you a weight penalty.

Lots of studies out there. This article has a long list of relevant references

Do you have access to that paper?
