[quote Dog-lover]My point exactly, Rotenone Scofield 4 or 5 times now and over-run with chubs today. Not a very satisfactory outcome at a very high cost. You could call it a repetitive failure.[/quote]
It's only a failure depending on the management objectives and goals of the treatment.
Do you have those objectives? (I don't)
I also don't have the info on the treatments. Were the treatments done in successive years (ie: 2 years in a row)?
Some fisheries have rotenone treatments as part of the management plan. Lakes like Johnson Reservoir were treated on a fairly regular basis. Those treatments would provide 4-5 years of good trout fishing, followed by a few bad years, then a couple years of nothing, followed again by 4-5 good years. The alternate is what we have today: no trout at all. No treatments mean no trout fishery at all. It has to be replaced with something else, or abandoned completely.
sometimes we reap exactly what we sow.
