Abstract

The major objective of stock assessment programs is to manage fishery resources by providing advice on the optimum exploitation (Sparre and Venema, 1998). Thorough knowledge of the stock structure of the target species in commercial fisheries forms the basis to formulate resource management strategies (Shaklee and Bentzen, 1998). If the stock structure is not considered while formulating plans for fisheries management, it can lead to the collapse of the population due to the changes in biological attributes and loss in productivity rates (Begg et al., 1999; Cadrin, 2005). Stock structure analysis is, therefore, a pre-requisite for developing fishery management plans to understand the existing levels of recruitment that may replenish the population (Cardrin et al., 2005).
