I'm not aware of any peer review published studies on the relative productivity of hatchery fish using native brood stock. Some of the prelim info that I have heard about seems to indicate that those hatchery fish are not much less productive than the native fish - the numbers that are kicked around is about 90% as productive for the HxH and HxW crosses. I suspect that it will be several more years before there is more detailed information. The ultimate answer will likely depend on how different the selective pressures are on those fish raised in the hatchery and those that are produced by the natural system.

Clearly those established hatchery brood stocks are less productive and any new brood stock; even those using wild fish have the first step down that slide of lost productivity cause by domestication.
