Wild stocks at carrying capacity does not mean more harvestable biomass when stock has been selected to avoid lures. Stocking on top of such stocks can result in more fishable populations where stocked fish are preferentially harvested.

There is a good reason for this. If you take wild salmon or anadromous trout, and raise them in hatcheries, they will have a good number return to the stream they were released in. But if you raise many generations in a hatchery, they loose wild characteristics like being anadromous.
For example, ohio at one point raised its own steelhead at the London hatchery. They had only a small number come back each fall. More recently, ohio gets eggs from michigan's little manistee river. 4 little manistees come back for every one London.
Habitat restoration is always a good thing.
