The only explanation that I can fathom.....since nobody is helping me out here.....is that once the fish is removed from the surface of the water (and ONLY then) the decompressing/expanding body, including stomach, bowls, ect., might ingest air (the same air that WE breathe). Gases, from digestion of food, is the fishes only way of producing anything buoyant. Aside from surface-air gulping gar of course.
So theoretically, if the fish was scooped up in, and kept submerged in, a bag of water while being unhooked and transferred to the livewell....then there would be no "fizzing" necessary.
Merely being pulled from deep water to shallow water can not cause an immediate buildup of oxygen or gases. If it could then all of our energy concerns for the future would be solved for good.
So ok? Who's smarter than me NOW? 😜 Bunch of dumbasses ! 🤣
