If you catch fish at 50' with any appreciable numbers then you will be going against some pretty solid biological evidence that it shouldn't be happening, Bubba!LOL! You will have a bunch of us scratching our bald or balding heads right along ie I also wanted to express my gratitude to Jim Hakala! What a great asset to have on this board!!! Thanks!
Bob, Me and Robert Eidson were doing something very similiar to this a few years ago ie catching fish below the registered cline.. I can't find that post but I remember showing some sonar shots that showed fish schooling well below the DO line. But like Jim said I guess they can hold their breath and you can catch them below it as I have no other way to explain it other than it happens LOL. I'm certainly not arguing Jim's data as I believe it to be 100% accurate as my dads a retired oceanograher for the Navy (30 years) and tells me the same thing exact thing as Jim..
Here is another similiar post that I found wayyy back in the archives that you might find interesting. Maybe Ray can hound dog that other post (I can't find it as the search feature on the forum kinda sux).

I just spent about an hour on different internet sites reading about the importance of DO (dissolved oxygen) to fish. MAN! That is some scary stuff. Check this out: * The most important thing to do if fish are dying from low DO is to turn on an aerator. If emergency aeration is not available, LITTLE CAN BE DONE TO HELP THE FISH. * On a hot, muggy, cloudy day the photosynthesis in the water slows down (because less sunlight can make it to the water surface). Slower photosythesis makes less DO available, BUT that is when the fish need it the most (because in warmer water, their metabolic rate speeds up and they need more oxygen) so that puts them in double jeopardy. * Lower DO hurts the bigger fish more (because they need more oxygen). * Low DO can result in blood embolisms that can kill the fish. Sometimes, the blood embolisms can be seen on their skin. I SAW THIS ON A SMALL SPOT. I HAVE A PIC OF IT. I WONDERED WHAT CAUSED IT AT THE TIME. * If there has been a long period of hot, muggy weather - and then suddenly a rainstorm or "cold snap" lowers the temp of the suface water, allowing it to mix with the "dead" water below, the low DO then permeates all of the water and results in massive fish kills. -- This makes me wonder if some of the bigger fish I've seen floating on the surface were killed not by boat propellers or anglers keeping them out of the water too long, but by low DO? --- There are hundred of good articles on this topic on the web. Here's one of them: www.palmbayflorida.org/publicworks/stormwater/documents/fish_kill.pdf *
Big baits intimidate the fisherman, not the fish! <*\\\><( "I like big baits and I cannot lie")
