Abstract

The fitness and survival of diverse organisms in a particular environment are dependent on the unique biological attributes of a species. The inherent genetic variation within species and populations provides the necessary impetus to thrive in the presence of dynamic environmental forces. Understanding the genetic and morphological diversity is the key to ensuring the sustainability of ocean resources, identifying adaptive evolution patterns and managing ocean resources. Sustainable fisheries management requires the identification of fish species accurately to preserve the biological complexity. Identification of stock structure is essential to devise management strategies specific to the stocks. Recent advances in molecular tools have enabled unambiguous identification and stock structure delineation enabling conservationists to plan management and conservation actions.
