The New Jersey Fish and Game Council, in coordination with the New Jersey Marine Fisheries Council, and the NJ DEP Division of Fish and Wildlife, has modified the regulations for American shad in the state.
According to public notice, effective January 1, 2013, the regulations for American shad include
All American shad fisheries (both commercial and recreational), in both marine and fresh waters, with the exception of the Delaware Bay, Delaware River and its tributaries, are closed (no possession, take or harvest).
The recreational possession limit in the Delaware Bay, Delaware River and its tributaries is 3 fish with no minimum size and an open season all year.
Commercial net regulations for American shad in the Delaware Bay, Delaware River and its tributaries will remain the same.
According to NJ DEP, American shad regulations were taken to comply with Amendment 3 to the Atlantic States Marine Fisheries Commission (ASMFC) management plan for American shad and river herring due to concerns about the significant coastwide decline of American shad stocks.
Working in conjunction with state partners from the Delaware River Basin Fish and Wildlife Management Cooperative (CO-OP), a sustainability plan for American shad was developed for the Delaware River estuary and subsequently approved by ASMFC's Shad and River Herring Board.
