正文(英文) | A new study published this week (7 January 2020) identifies a need for fishery managers to adopt clear objectives for the protection of seabirds and mammals. It is published in the Wiley journal Fish and Fisheries. An international team of researchers, led by Dr Simeon Hill of British Antarctic Survey, examined six fisheries in three oceans – the Pacific, Atlantic and Southern Ocean. In each case there is a well known risk that fishing could impact seabird and mammal populations by removing some of their food. Many of these populations are monitored, however, only one fishery has a clear objective for a monitored population.
The study identifies the characteristics of suitable “reference points” – statements of objectives that can be used to control fishing activities. Changes to population size might indicate that an impact has already happened, but management should aim to prevent impacts. Consequently, reference points should be based on information that provides an early warning of impact risk, such as changes in annual breeding success. Fishing activities should be controlled to maintain populations above agreed reference points. Dr Norman Ratcliffe, a British Antarctic Survey seabird specialist who contributed to the study adds:
Reference points for predators will progress ecosystem‐based management of fisheries by Hill, SL, Hinke, J, Bertrand, S, Fritz, L., Furness R.W., Ianelli, J.N., Murphy, M., Oliveros-Ramos, R, Pichegru, L., Sharp, R., Stillman, R.A., Wright, P.J., Ratcliffe, N.
