Abstract
This paper reviews about the applications of DNA markers in aquaculture genetics. The development of DNA-based genetic markers had a revolutionary impact on aquaculture. With DNA markers, it is theoretically possible to observe and exploit genetic variation in the entire genome. Popular genetic markers in the aquaculture community include allozymes, mitochondrial DNA, RFLP, RAPD, AFLP, microsatellite, SNP, and EST markers. The application of DNA markers has allowed rapid progress in aquaculture investigations of species identification, strain identification, monitoring genetic changes in stocks, parental assignments and reproductive contribution, genetic diversity, brood stock management, identification of genetic variability between and within stocks, pedigree analysis in selective breeding, assessment of genetic manipulations, genome mapping and detection of Quantitative Trait Loci (QTL) for various aquaculture species. Hence, in this review, the principle and potential power of each markers and its recommendation for specific applications in aquaculture genetics are discussed.
