Playing devils advocate here. From PFBC data, survivability of stocked trout is <5%. Also if these fish are inferior how do they out compete natives/wild?
I can see how the increase in fish numbers in a system would adversely affect forage and holding areas but i am also told that stockies eventually starve to death because of how inefficient they are. I agree that there are differences in the species in regard to aggressivess and preferred habitat needs. Both would affect survival.
I dont want to re start the stocked vs wild argument here. Financially it makes all the sense in the world to stop stocking on a state basis. However private money is different.
The more i read conflicting arguments, the more i question myself. Id rather be correct than win the arguement.
