Global warming is literally cooking our lakes, rivers and oceans as evident when it was recently reported that hundreds of thousands, possibly millions, of fish have died as a result of water temperatures reaching as high as 100 degrees in Iowa and Illinois at an enormous cost to the fishing industry there.
About 40,000 shovelnose sturgeon were killed in Iowa last week as water temperatures reached 97 degrees. Nebraska fishery officials said they’ve seen thousands of dead sturgeon, catfish, carp, and other species in the Lower Platte River, including the endangered pallid sturgeon. And biologists in Illinois said the hot weather has killed tens of thousands of large- and smallmouth bass and channel catfish and is threatening the population of the greater redhorse fish, a state-endangered species.
So many fish died in one Illinois lake that the carcasses clogged an intake screen near a power plant, lowering water levels to the point that the station had to shut down one of its generators.
Yes, it inevitable that as the temperature increases the water is no longer at the correct temperature for the fish and the oxygen content of the water drops, thus killing fish.
The solubility of oxygen is greater in colder water than in warm water.
Another consequence of climate change.
