Use of Size-based Indicators for evaluating long-term trends in Indian oilsardine (Sardinella longiceps) fishery

Size-based indicators (SBIs) are being currently used to evaluate the response of fish populations to exploitation, and may also lead to the development of an ecosystem based fisheries management (EBFM) approach. At a population level, the selective removal of larger or smaller fish will be reflected in changes in mean length (L mean) or mean weight (W mean), maximum length (L max) and minimum length (L min) of the population.
