Abstract
Among all the exploited natural animal resources, fisheries resources are the largest. The magnitude, dynamics and resilience of fish stock pose great challenge to their assessment as well as management. The fishery resources are unique at least on three factors (Vivekanandan, 2005). (i) Many species have wide spatial distribution. (ii) Several species show wide temporal variations in abundance. (iii) Since the resources cannot be seen visually, gaining an insight into the structure and function of the resources is a challenge. It is reported that 667 marine species are fished (Sathianandan et al., 2013) by 194,490 boats (DAHDF and CMFRI, 2012) along the Indian coast, showing the dynamism of fisheries. To exploit these resources, to manage and develop the fisheries, and to conserve the fish stocks, it is essential to have accurate information on these stocks such as how much or how many are present in the sea, what is their reproductive capacity, their growth potential, etc.
