Quote from: oc1 on Today at 06:36:31 AMit's an either or thing. There's a 'venting tool' where you pop a hole in the swim bladder to release the pressure and help them swim back down. Or there's the descent tool. The idea is the heavy weight gets them down to the depth where their internal pressure is ideal again so they don't need to be vented.Quote from: Gfish on April 24, 2024, 07:36:48 PMNow that I'm thinking about it, how slow would one haveta crank a bottom dweller up to prevent major gas expansion(swim bladder)and blood embolisms from occurring? I know, but I didn't wanna start a whole new thread... Deep SCUBA diving with standard equipment/breathing gas, requires several timed stops on the way back up to rid yourself of excess Nitrogen, so you can avoid the bends.
In florida they're using a gizmo that you clamp a captured fish too and drop it to 100 feet quickly with a weight. Once it gets to 100 ft the gizmo opens the clamp and the fish swims free. I think you're supposed to relieve pressure on the swim bladder first.
