Fish 2 equals fish 1 the following year. Nice theory but fundamentally flawed.
Uh, what?
Fish 1 and Fish 2 get to spawn in Year 1, Fish 1 is netted in the fall, Fish 2 spawns next year. That’s three “spawns”.
If netting occurs in the spring, and Fish 1 is netted, and Fish 2 lives until next spring (and lets say it misses getting netted again) that’s two “spawns”. Even if the only benefit is in the first year, the overall number of spawns will always be greater. Also netting in the fall will most likely reduce the amount of fish taken, since they’re typically not as bunched up.
And Feathers, I would love to know what lakes you’re panfishing that haven’t suffered to some extent over the last couple decades. Aside from farm ponds and hidden gems, the vast majority of the state’s panfish lakes aren’t anywhere near what they used to be. It’s gotten better over the years, but I still don’t have much faith in John Q Weekender and his buddies’ abilities to self-regulate. Ignoring the fact that your average Dakota glacial lake has a much healthier forage base due to the grass shrimp, they also (to my knowledge) don’t have any netting. Those guys that you chuckle at for fishing the spawn probably throw a lot more back than the nets do.
At the end of the day I don’t really get why we’re arguing about this. Moving netting to the fall is a bad idea because it “might” not help? Again, whether or not it affects the amount of eggs laid, I would be shocked if they net nearly as many fish when they’re not concentrated in shallow due to the spawn. That alone should be enough of a reason for all of us to be in favor of it.
