(a) Any local or general law of the State which sets or regulates minimum and maximum sizes of fish, or regulates or prohibits the sale of fish, applies whether the fish are caught in the waters of the State or in the waters of any other state, county, or territory and brought into the State. Any fine or penalty prescribed for violation of these laws applies to the same extent.

(b) Notwithstanding any general or local laws or ordinances to the contrary, finfish, crabs, oysters, clams, and other shellfish, caught in the waters within the jurisdiction of the Potomac River Fisheries Commission, in compliance with regulations prescribed by the Commission pursuant to the Potomac River Compact of 1958, may be possessed, stored, marketed, and otherwise disposed of elsewhere in the State.
