The impact of the striped bass is not untenable or anything. If you have a big year for bass, then they will eat lots of baby salmon, mostly. The smallmouth bass will maybe do the same thing up in the river on the parr. The thing is, natural mortalities are pretty much adjusted by the population dynamics. If you have high mortality in one place, that tends to lower the mortality somewhere else.
When you have a directed fishery, there is absolutely no way the population can adjust to it.
