Biobanking and genetic markers for parasites in fish stock studies

摘要

The use of marine parasites as biological tags in fish stock studies over the last 60 years became a widely accepted method commissioned by scientific and fisheries agencies, and the results were included in species reports of fishery management plans. Much effort has been made to understand the ecological role and applicability of a wide diversity of parasite fauna as tags across major marine areas and oceans, especially for the main fish stocks and fishing grounds. Herein, we explore biobanking and genetic marker challenges as tools to be used for fish stock discrimination. First of all, we discussed about well-recognized major gaps identified by researchers, managers and end-users that improve the usefulness of parasites as tags. Secondly, we suggest the potential of under-exploited biobanking and molecular markers as promising technical solutions, which could play a future leading role ensuring such a priori high discriminatory power of marine fish populations based on parasite data.
