The use of microsatellite marker in estimating genetic relatedness for domesticated Asian sea bass (Lates calcarifer) broodstocks

Regarding the importance of aquaculture industry development, it is necessary to focus on inbreeding in artificial propagation to prevent genetic diversity reduction and problems arising from low genetic variation. Indeed, lack of facilities and the rules related to the responsible transportation of live aquatic animals, and carelessness on health- diseases control in farms has led to some diseases outbreaks which have imposed high costs for farmers, including huge losses or cure. Therefore, it is required to identify the species and population traits before initiating any culturing or breeding programs and evaluate them with molecular genetic methods to synchronizing study with biological characteristics such as reproductive potential, growth rate, and mortality. Achieving broodstocks and fry owning genetically relatedness is a principal issue in each hatchery. This article tries to discuss the significance of genetic diversity assessment by microsatellite marker for broodstocks' genetic relatedness, with an emphasis on Asian sea bass.Keywords: diversity, pedigree, Asian sea bass, marker
