Maintaining big data projects takes a lot. A lot of people to conduct research, populate databases, verify information, make the data accessible. It also requires a lot of material and financial resources.
Twenty-six fish and invertebrate populations that live in the waters of eight West African countries are likely overfished or at risk of being overfished, a new Fisheries Centre Research Report reveals.
Preliminary results from the application of the CMSY and LBB stock assessment methods to fish populations in the EEZs of Cape Verde, The Gambia, Guinea, Guinea-Bissau, Liberia, Mauritania, Senegal and Sierra Leone, indicate that some stocks – such as that of cassava croaker off the coast of Liberia – are strongly overexploited.
In the first study of its kind, researchers from the Sea Around Us initiative at UBC, the GEOMAR Helmholtz Centre for Ocean Research Kiel and the University of Western Australia assessed the biomass —the weight of a given population in the water— of more than 1,300 fish and invertebrate populations. They discovered global declines, some severe, of many popularly consumed species.
