Cliff - why do they quit taking spawn when they haven't filled up to capacity, and the spawn is still active? Years ago my dad was convinced that the DNR took adult walleyes out of Vermilion and transferred them to other lakes; do you think that ever occurred? The hatchery is beneficial to Vermilion and other lakes, but why do they plant fry in lakes where they have no chance of reproducing? Aren't there enough lakes where they can reproduce to some extent to plant them in?
Well it didn't take long for "that guy" to show up.
It shouldn't be too difficult to understand why I'd rather fish for trout than buy them at the store...
Do they holdover though? I thought that was a lake stocked right before freeze up and then all but completely fished out after the Winter opener.
Assuming the ratios given to Cliff by the hatchery are accurate, then:
With Hatchery: 708 quarts X 100,000 eggs is 70,800,000 eggs. Survival rate is (low end) 75%, so total fry is 53,100,000. If 10% go back into Vermilion, that's net +5,310,000 new fry this year.
Natural reproduction: 70,800,000 eggs at 3% (high end) survival rate would be net +2,124,000 for vermilion this year.
5,310,000/2,124,000 is 2.5X the walleye fry in vermilion this year compared to natural reproduction.
I'd take a 250% return on pretty much anything!
Ancillary benefit is +47,790,000 fry to other MN waters.
I'm sure there's a downside, but I can't see it.
