I did a little searching Biggill and couldn’t find it. Which might be due to the Lindner video barotrauma video “was a pilot project. Information gleaned from this project will be used to refine research on the barotrauma issue.” So it doesn’t sound like it’s been published yet, and may never be if it’s included as part of a larger study. Maybe Dee J is sobered up and off of his throne today, and could explain how he read it already. Or confirm he was lying.
I spent some time looking for it as well and could t find it. I’d still like to see a report or something on it. I understand it’s a pilot study but if you can’t even find out what the methods are, it’s hard for people to suggest improvements.
I did a little google research on barotrauma today and it seems like the main enemy after bringing them up from 33’+ is how long they are kept above their neutral buoyancy depth. Handling and keeping them out of water probably doesn’t play a huge factor but rather the time spent above their target depth will begin to cause damage when the air begins to burst blood vessels in their gills and organs. The longer they stay there the more damage that occurs. The only way these fish can relieve pressure is by reabsorbing the gasses from the swim bladder back into their blood and ultimately out their gills, if I understood it correctly.
So thinking back to the study, Aaron’s concern about handling was generally correct. The longer they are held above their natural buoyancy depth, the more damage that occurs.
