What would our walleye population be if they shut off lake mac from the dam from April 1 to may 1? Just a thought. Anyone can go pull cranks and hook a female full of eggs. She may hold up to 250000 eggs. If half get fertilized that is huge, or is it better to hang her on the wall?
I can answer that real easy–if fishing was not allowed during the walleye spawn your walleye population would be exactly the same as it is now.
How many eggs do you suppose are produced by the female walleyes in McConaughy? How much of that potential reproduction is taken by anglers? I cannot answer that for McConaughy, but I have crunched some numbers from Harlan years ago. There was a year when we collected eggs from Harlan, had a population estimate of the numbers of walleyes in Harlan and had an angler survey during the spawn period to estimate the numbers and sizes of walleyes that anglers harvested. There were over 1 billion walleye eggs produced by that walleye population that year, and if every female harvested by anglers during the spawn period was full of eggs when harvested, anglers removed 2% of the spawning potential. Suppose 98% of 1 billion eggs was enough to maintain the Harlan walleye population, a population that does have significant natural recruitment?
I am sure there are even more eggs produced by the McConaughy walleye population and even less of that spawning potential harvested by anglers during the spawn period. Oh, and the walleye population in McConaughy is maintained primarily by stocking.
As a matter of fact, there are more female walleyes harvested during the months of May and June than are harvested during the spawn period. If we need to protect adult walleyes then they need to be protected year-round; it makes no difference if they are harvested in April, 2 hours before they spawn, or in May, June or October, months before they spawn again. If we needed to protect adult walleyes, we could protect more by closing the season during Memorial Day weekend than we could by closing it during the spawn; I am betting no one would be in favor of that. We do have a daily bag limit of no more than one walleye larger than 22 inches, statewide, and I encourage anglers to selectively harvest the small and medium-size walleyes (as long as they are legal size) and release the big fish, all the time, year round.
We have some anglers who like to fish for walleyes during the spawn and some of those anglers hardly fish for walleyes at any other time. As long as anglers are not having a negative impact on our resources, we want people to fish!
