Except triploid and other nonreproducing forms, species may be propagated in the same watersheds within which they are allowed to be stocked.(b) Initial list of approved species. -- Except for those species of fish allowed for stocking only in a triploid or other nonreproducing form, the initial list of approved species shall include all species approved for artificial propagation or stocking by watershed as listed by the commission on January 1, 1995.

The initial list shall be submitted to the department within 60 days of the effective date of this chapter.(c) Closed systems. -- Special regulations shall be promulgated regarding the cultural methods for species of fish allowed to be propagated in systems which do not discharge water into waters of this Commonwealth.
