This document presents current status on genetic diversity of empurau and semah in Sarawak, Malaysia, including taxonomic status and a management guideline based on genetic data. Inadvertent mixing of the two species, especially during breeding, may lead to hybridisation, a threat to the genetic integrity of wild populations. Surveys on current status of genetic variability of empurau and semah are reported herein, and the results from which are used as baseline data for development of a genetic management plan.

This manual provides a comprehensive practical tool for the generation and analysis of genetic data for subsequent application in aquatic resources management in relation to genetic stock identification in inland fisheries and aquaculture. The material only covers general background on genetics in relation to aquaculture and fisheries resource management, the techniques and relevant methods of data analysis that are commonly used to address questions relating to genetic resource characterisation and population genetic analyses.

This is the second part of the manual Application of molecular genetic techniques in aquaculture and inland fisheries management. It provides a step-by-step laboratory protocols and methodologies for data analysis and a guidelines to design a population genetic study. The scope covers most commonly used techniques for screening genetic variation, general background on the methodologies for estimation of important parameters in population genetic studies for different forms of molecular genetic markers.

The aim of this manual is to provide a comprehensive practical tool for the generation and analysis of genetic data for subsequent application in aquatic resources management in relation to genetic stock identification in inland fisheries and aquaculture. Part 1: Conceptual basis of population genetic approaches provides a basic foundation on genetics in general, and concepts of population genetics. Issues on the choices of molecular markers and project design are also discussed.

L'élevage de la crevette est l’un des secteurs d'aquaculture le plus en essor dans beaucoup de régions du monde, il est également l’un des plus controversés. L'expansion rapide de ce secteur a généré, certes, des sources de revenus pour plusieurs pays, mais elle a été accompagnée par une préoccupation croissante sur les impacts environnemental et social. Les Principes Internationaux pour l'Elevage Responsable de la Crevette fournissent la base sur laquelle les parties prenantes peuvent collaborer pour un développement plus durable de l'élevage de crevette.
