[quote Fishrmn]It's a game of numbers. If you have the ability to kill 10,000 adult chubs every year with Tiger Trout you're falling behind with every 3 or 4 female chubs that survive. If you have enough Tiger Trout to eat 1,000,000 adult chubs every year, you fall behind even if only 300 or 400 adult female chubs survive to spawn. And that's not counting the 100s of millions of chubs that aren't adults.
If you start with a clean slate, and have enough predators (Bear Lake Cutts and Tiger Trout) that they can eat 95% of the young of the year chubs then they will have enough effect to hold the chubs in check. Right now, they can't stop enough chubs from reaching adult size and reproducing.
Even if a rotenone treatment were 100% successful, I've already wagered that some bone head will plant chubs back in Scofield after any treatment, should it happen.[/quote]
The chubs will always win. Even if you poison it and restock it...it's only a matter of time before we end up right back where we are now. This reminds me a lot of people talking about "getting the burbot out of the gorge"... I have two words: Good Luck!
[quote MasterDaad]Let's make sure we don't get ahead of ourselves claiming a conclusion to the Scofield question.
I think that's why some people think it is going to happen -- because those of the opinion it should or will be poisoned sometimes speak in terms too absolute for the situation.
There's a study ongoing and an open question.
Let's wait and see what the conclusion actually is.
Fair enough?
As for the impact on the trophy fish... Poisoning the lake absolutely will destroy Scofield as a trophy destination for several years to come unless the DWR has a nice batch of 25" trout to toss back in to get it going again.
That said, down the road the potential certainly could return -- in a 5 -10 years.[/quote]
That is my thinking exactly. Yeah, they will stock tigers in there again, but you are looking at 8-10 years before you see 18lb fish in there again... especially since they won't have the food supply they had before (at first...until they come back). Kill all the trophy fish in there, with the chubs,... so that smaller trout can grow quicker... but the chubs will still return eventually (in full force too).... seems counter-productive to me to poison it (1$ million+ [shocked])
Just fun discussing it even though it's out of our hands.
