JohnR & Specialist, I don't know what would happen with the bladder coming up on the fish, I have seen on some of the fishing show, how they will poke the bladder with a needle and then release the fish. This way the fish will return to the bottom and be OK.
How many fish do you think come up in a big dragger net from deep water and have there bladder in their throat. Also all of the other species that they may be picking up as by catch which end up dead because of all the weight in the net. At least if you are catching one or two at a time you have time to at least puncture the bladder on the smaller fish and then release them. Just my opinion and I am not trying to stop peaple from making a living, but if there is nothing left out there to catch, your not going to make a living that way either.
