Salmo,
Health advisories in Pa regarding fish flesh contamination, including “do not eat” advisories have traditionally been based on fish flesh contamination analyses.
If and when stocked sections are removed from the stocking program, fish from those sections are stocked elsewhere, often in waters closest to the section(s) that were removed from the stocking program as long as those waters are not already being stocked to the max allowable within the classification system. ( I don’t happen to agree with this adaptation unless those waters being stocked below the max already receive very good to high angler use and actually NEED more fish on the basis of their usage; otherwise the fish should go elsewhere). Alternatively, when available, new local waters may be added to the stocking program to accept these fish. This option is often not available, however, because the good local options are already being stocked.
