Abstract

Fish stock identification is a process in which the commercially important aquatic organisms advice to exploitation of fisheries resource on maximum sustainable yield to maintain fisheries resource for future. “Fish stock Stock is a subset of one species having the same growth and mortality parameter, and inhibiting in a particular geographical area”. By tagging we can get data/ knowledge about fish route of migration, by the same way we can obtain the trends of exploitation of aquatic organism. Now there are numerus pathways for biogeographical isolation/ recognition of stock such as marking, tagging (natural and artificial), meristic and morphometric characterization, hard part (scales, bones, and otolith), molecular tools etc.
