The question was raised in the "Mosquito Muskie Rumor" thread is to why Ohio has so little natural reproduction as compared to places such as Canada. I forwarded the question to Elmer Heyob of the ODNR. I also asked him about muskies returning to Lake Erie. He was kind enough to give a very good response: "Hello Mr. Quigley, I will be glad to answer your question. What we lack are "nursery areas" for the fry that do hatch. The muskies spawn just fine but it's an extreme environment in most of our Ohio lakes in the spring for fish that our broadcast spawners like walleye and muskie. Having raised muskies at one of our hatcheries, I know first hand how difficult it is to keep fungus from forming on eggs and fry due to poor water quality. Think about how often our lakes make it through April without having muddy water conditions? Once these eggs hatch, the fry need an almost immediate supply of quality food to keep from starving to death. Without abundant forage they will quickly turn to cannibalism and their numbers dwindle rapidly. Now, add in the fact that without proper habitat, ie., protection from predators by using thick cover, they quickly vanish. The one rare situation in Ohio when we have seen significant natural reproduction by our muskies is when flood control lakes hold back high water for at least a three week stretch that just happens to coincide with muskie spawning. The water within the flooded grass fields quickly clears, unlike the main lake, and is ideal habitat for young muskie fry. Unfortunately for us fishermen, we aren't allowed control our lakes for best fish management. Flood control and water supply are the type priorities and even Parks might frown if we wanted to keep the water levels high because it would interfere with other recreational pursuits. There are muskies scattered all up and down the southwest coast of Lake Erie in small numbers. I have a feeling though that we may not see any significant rise in these numbers for several reasons but I hope to be proven wrong. One is the fact that the Canadian border of Lake Erie is almost a continuous line of gill nets, which are deadly to muskies. The other is, we have allowed almost all of our bays to be developed and wetlands drained, leaving very little natural spawning habitat left. Elmer "
