Conservation and fisheries
Simon Jennings (Cefas, UEA)
The effects of fishing on many species are not understood; usually because management and conservation bodies have struggled to obtain necessary information on status, risk and potential yield. The information gap is especially wide in poorer countries in the tropics and sub-tropics, where species and catch compositions are diverse but resources to assess the status of individual populations are scarce. Researchers from UEA on the Norwich Research Park have developed methods that use widely available life-history data, such as maximum body size, to predict conservation and management reference points and associated uncertainties. Methods have been applied to rank the risks to large numbers of fish species and to define reference points for sustainable fisheries management.
