I've wondered how they do this test for mortality. Do they catch say 50 fish, tag all 50, then see how many of the tagged fish bubble to the top? How can they be sure they found all 50 tested? How can they be sure all 50 were hooked exactly the same way, and were all at the same depth? Do they catch the fish and check their overall health, before subjected the same sample group to being hook caught, tagged then released? I just wonder what the controls are on their data sampling. And teh sampling data article said after being caught, the stripers were put into a controlled environment tank where the researchers watched for the fish to react or die. So how do we know this doesn't only prove Stripers have a high mortality rate when held in tanks?
