Dependence of recruitment on parent stock of the spiny lobster, Panulirus argus, in Florida
Abstract Despite management practices to achieve sustainability, commercial landings for Florida spiny lobster ( Panulirus argus ) have experienced a drastic decline (57%) since 2000. This is cause for concern not only for economic reasons, but for issues of sustainability. An annual index of P. arg...
