From a previous posting: The lake, according to Mn. DNR figures, has about 1 million pounds of adult age/spawning size walleyes. Nowdays, I would guess the average weight is around 4 lbs. or a hair more or less. Now, on a big weekend, it is not unheard of having 3-4000 (or more on the Opener) boats on the lake. That breaks down to about 250,000 walleyes in the entire lake. (comparable to years back–pre-netting era– when there was 2.5 million lbs. that averaged 2lbs. or less) So instead of having over 1 million adult walleyes to fish for–or about 200-300 or more fish per boat—you now have about 40-60 per boat. In other words, if the average boat lands 20-40 fish per day almost ALL the fish in the lake are potentially getting fished and or caught? To me….that is a very telling set of numbers………half the weight of fish in the lake but only one fourth to one fifth the actual numbers of fish.
Unless my math or figures are off? LOL My weather beaten brain might be way off? Think about that for awhile…end quote:
And now more to consider—for awhile…
If there is around 250,000 adult walleyes in the lake now and no new year classes coming since the 2008 group, how long before the lake is void of walleyes?
So if we harvest a few 18-20 inch fish and the total including mortality this year (2013) is around the quota number allowed (approx. 175K lbs.) that means at a 3-4 lb.s average, we kill around 40 to 50,000 walleyes right? And the nets, that average about 2lbs. per fish, kill 50K lbs., that total is around 25,000 walleyes right? So we kill around 75,000 walleyes in 2013.
Figure in a natural mortality as the big ones get old and die……
So–not much in year classes coming up , per the DNR, how long before the 250,000 we have in the lake are gone? It takes around 4 years for the 2013 hatch, if it survives well, to get to “adult” level, right?
Do the math? In 4-5 years, at the harvest rate you have now and projected into the future……what is left?
Maybe the DNR numbers are wrong or the year classes between 2009 and 2012 are big enough to keep things status quo? Or did they say those year classes are very small or non-existent–relatively speaking?
Now does anyone question how I can suggest closing the lake to walleye harvest NOW? Or should we wait and see what’s gonna happen? Maybe my math is wrong or my long term view is wrong or ??
