| 3b. Genetic mapping, manipulation and breeding of aquatic species |
| Various genetic studies have been pursued to improve commercially important traits such as disease resistance, fast growth, high fecundity and high meat quality, in a wide range of aquaculture species from vertebrates, invertebrates and algae. This sub-session highlights modern genetic approaches such as marker or gene assisted selection, linkage mapping, radiation hybrid mapping, physical mapping, QTL (quantitative trait loci) analysis and comparative synteny as well as conventional approaches including genotype-environment interaction, selection, hybridization, inbreeding, and ploidy-manipulation. Basic studies including molecular genetics for developing new polymorphic microsatellites DNA and single nucleotide polymorphisms (SNPs) markers, cytogenetics with fluorescence in situ hybridization (FISH) and banding, and quantitative genetics for estimating heritability in aquatic species are also covered. |
