Dave,
I will look for info for you.
Trust me it is real and should be a concern to people.
There are also TWO different types of "Hot Water" which most people who don't buy the "hot water kills fish" theory don't really understand.
Here in Indiana our lakes are very small and warm up very quickly. The warm water penetrates the water column ALOT faster than they do in northern lakes found in Wisconsin and Minnesota. Oxygen levels go down, and the thermocline sets up. There is really no usuable oxygen below the thermocline. So, say the thermocline is at 15 ft. Well here in Indiana our water temps will be at 85 surface and 80 degrees 15 ft. down. Muskies can't survive with the stress of being caugh and fough in water that is very warm, with very little oxygen, then released back into the hottest part of the water column.
Lake in Mn, Wi and Canada hit 80 degrees from time to time, yet after a cool night they are back down to 75, 73, etc... Our waters don't ever really cool down, so the pentration is deep in the water column.
I have been out with Jed Pearson, our head DNR biogiest and did an oxygen study with him. We also looked at water temps at 1 ft. all the way down to 16 ft.....water temps were above 80 and almost no oxygen present anywhere....the weed kill doesn't help this either....I then went out with my oxygen senson and temperature guage along with my aqua view with John Bette from Stealth Tackle. We saw many fish with signs of being caught laying on the bottom dead.
When I was younger and didn't know any better, I killed a few in my day by fishing in hot water. Fins were gushing blood, gills were really pale in color, etc...put the fish back in the water...and belly up she went.
Trust me it is true and legit. Why do guides in Kentucky, Illinois, Indiana head north for the summer months? So they don't kill muskies. Tony Grant who guides in Kentucky told me about a 50+ that died last week before it even hit the net. He is already in Wisconsin, but one of his friends told him about it. Gregg Thomas will tell you the same, as will Chad Cain who has a degree is fisheries biology. High water temps kill muskies.
Doesn't muskies Inc still run an ad that shows a dead musky and says something about high water temps kill fish????
It all has to do with the high water temps, the penetration of the warm water, little oxygen in the water and being released back in the hottest part of the water column.
I know Steve Fiorio who lives on the Barbee Chain has seen a few dead muskies floating after trying to be released in hot water.
I'll see what other info I can find. If any of you have anything to add, please do so.
Thanks,
