Sea-based aquafarming and traditional fishery: Oceans apart?

Building multiscalar sustainable ocean governance: How do global perspectives interact with the Portuguese national approach?

“…The “Blue Basic Farmland” (BBF) is the farming ocean area that cannot be changed according to the ocean use plan. Unlike the basic farmland on land, the Blue Basic Farmland establishes that there is competition between mariculture and fishermen for the use of the ocean [ 8 ].
