I am actually shocked that there is not better technology than the radio tag process described. That would definately not work and would largely skew the results in a negative way.

If I catch a Striper on a board in less than 5 ft water in Summer, I have no doubt that I can release the fish quickly and chances are excellent it will survive. If I catch a fish deep, it is going to die and needs to go to the cooler. We have this discussion every year. It is a put and take fishery and a personal choice.

The study a lot of people cite involved 5 radio tagged fish.
"Of those five fish, one was dead at boatside, two died within 5 minutes of tagging, and the last two were found dead the next day."
I wouldn't base much of anything on a sample size of 5, no matter what was done to them.
Later, the same report says this:
"The striped bass found in Lake Martin are Gulf-strain fish, which may be better, adapted to higher temperatures and lower dissolved oxygen concentrations than Atlantic-strain fish"
The point of my original post is the in-situ observation of a striped bass going from stationary, floating to active, swimming away on its own at surface temperature water in July. I don't see how a fish self-revives in water that is so low in oxygen that it cannot get enough air to function.
Finally, when SML had the large fish kill off due to copepods (if that was the cause), how many of these dead fish floated?
Sorry if it's just the same discussion year after year. I'm a noob.

Not much of a study. I wonder how long they were out of the water having the transmitter inplant operation. I also wonder if being cut open and having a transmitter implanted in the fish does not also increase the probability of death. I know if you just took me of the operating table and threw me in the water, I would probabily not make it.

When the fish kill happened, my wife, mother-n-law and myself counted 246 dead stripers floating or washed up on the bank one Saturday at the dam. The crows were having a feast on the ones washed ashore. The dead fish were everywhere you looked. Were there that many or more on the bottom, I hope not. About having the same discussion every year, don't sweat it. There hasn't been anyone ranting or going crazy this year. I actually enjoyed hearing everyones thoughts and opinions this time....

Caught 2 nice stripers at buggs 3 weeks ago while LMB fishing. ( go figure), Pulled them up from about 30-35 ft while deep cranking. I put them in the live well & they floated imediatly. I decided to try fizzing them(down the throat,not through the side). Within a minute they were swimming lively. I added a little ice & rejuvenate & kept fishing. Three hours later they were still swimming so I decided to release & see what happens. The first swam straight down like a torpedo, the 2nd shook out of my hands before I got him to the water & it too darted off with plenty of vigor. Obviously I don't know for sure if they survived but I have a good feeling they did. Was it the release of pressure from air bladder, cool water in live well,livewell additive, or combination of all. I don't know but surely if you put them quickly back to the conditions they're used to they can survive.

Would you mind describing this process: fizzing?

Fizzing is the process of using a needle to puncture the air bladder of a fish to release air which has become engorged with air due to the change in pressure when the fish is reeled up from deep.
Most of the reading I've done indicates fizzing is not effective on stripers and can lead to increased mortality.
In the case above, the time with the fish in the livewell, with cool water & good circulation/aeration likely allowed the fish to recover. If not fizzed it would have slowly released the pressure while in the livewell. I've seen similar situations occur before with small (sub 8 lb) fish.
