[quote PBH][quote BassDuder]So increase the harvest of all sizes of SM. and improve the spawning habitat for the perch and it's a home run. What the worst that could happen?[/quote]
If you improve the perch spawning habitat, then you gain nothing by removing smb. The spawning perch would simply occupy the space opened up by removing the smb.
Aren't perch spawning right now? They aren't being stocked, so obviously they aren't having any trouble reproducing and keeping their population numbers high. What good would improving their habitat do? We'd be better off wrecking their habitat and limiting their spawning recruitment to "partial" success rates.
Adding more perch won't help. You have to remove fish, not add more.[/quote]
[#0000FF]That does it. Now I am absolutely convinced that you know nothing about Jordanelle...or its current ecology. You need to stop reading the old reports from your brother's observations...from ancient times.
1. There are no chubs, shiners, or other minnows in Jordanelle...and virtually zero crawdads.
2. Since the chubs disappeared, perch have been the ONLY source of forage for smallmouth and larger trout.
3. The perch population crashed several years ago and there are VERY FEW perch in the system. And the young are consumed by the smallmouth as fast as they can reproduce. THERE ARE NOT ENOUGH PERCH IN THE SYSTEM TO FEED THE PREDATORS...AND THE PREDATORS HAVE NOTHING ELSE TO EAT.
4. You advocate restricting the spawning habitat and recruitment of perch. That would be like filtering out all the zooplankton from a kokanee lake. Or having a mass dieoff of shad in Powell. Or any other ecological system you may understand better than Jordanelle.
I used to think Cliff had the exclusive on dense.
