Br0wntrout -- you brought up a couple things that bring out my point.
"[font "Verdana,Arial,Helvetica"][black][size 1]The largest factor that contributes to size is oxygen."
[/size][/black][/font]
While I don't believe this, it still shows that strain isn't the limiting factor in size. You are saying that oxygen is the limiting factor. If levels of oxygen aren't sufficient to produce a 20" fish, then why would strain make a difference?
Generic rainbows. What's a generic rainbow?
Utah uses many different types of rainbows, from Fishlake / Desmet, to Sand Creek's. They all have different qualities which make them better suited to the environment they are in. Sand Creek's spawn at a different time of year than Desmet, which makes them a better fit for Minersville Reservoir. Kamloops would be a terrible fit in Minersville because of spawning time of year. They'd never make it past 8" because bird predation would wipe them out.
With Strawberry, again, how would Kamloops perform any different than the current strain of rainbow? Before thinking that Kamloops would perform better, don't we need to identify what is currently preventing the current strain from growing larger than they currently are? Same with Flaming Gorge.
So, for anyone wanting the DWR to change rainbow trout strain in any reservoir, let's identify a couple things:
1. What is keeping the current strain from growing larger?
2. What are the benefits (why?) of using the current strain?
3. Are the limiting factors something that can be changed?
Br0wntrout: you first. What are you answers to 1-3?
