متن کاملIntegration of fishers’ ecological knowledge in fisheries biology and management. A proposal for the case of the artisanal coastal fisheries of Galicia (NW Spain)
The fisheries crisis of the last decades and the overexploitation of a great number of stocks have revealed that the scientific knowledge available about the dynamics of the marine ecosystems and needed for the management of the fisheries is inadequate. This problem is critical when the management of coastal ecosystems and artisanal fisheries is involved. These systems show a great complexity d...
