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. For example, decrease in the mean size of a population may either point to overexploitation or to enhanced recruitment. Besides, influence of environmental factors will also play a vital role in determining the success of recruitment, growth rate and condition factor (Kn ) of the population. Thus SBIs are a cost effective tool to evaluate the effects of fishing on a population of fish, and have been used for several temperate water species such as cod and plaice.
