This article discusses the various environmental effects and variations that can affect the phenotype of fishes such as stocking density and mortality; age, temperature and water quality; biology and physiology; natural effects; correlation of growth data; maternal effects; correlation of growth...

This chapter covers basic genetics, qualitative traits and selection for qualitative traits and their use for the genetic enhancement or maintenance in aquaculture and fisheries. Focus is given on dominant and additive gene expression, epistasis, pleiotropy, lethality, penetrance and expressivity,...

This chapter covers strain evaluation, domestication and strain selection and their applications in aquaculture, particularly fish culture. Focus is given on genetic improvement programmes, natural selection in strain development, domestic and wild strains and strain effects on other breeding...

This chapter describes the general concepts of inbreeding, the negative effects on inbreeding on fitness and the application of these concepts on the breeding and maintenance of genetic diversity in aquacultured species.

This chapter describes the beneficial effects of crossbreeding on the growth, survival, reproduction and disease resistance of aquacultured animals.

This article discusses the principle of interspecific hybridization in different aquaculture species. The potential benefits and advantages of interspecific hybridization in aquaculture are highlighted.

This article discusses the heritability; genetic controls; practical aspects of selection; individual and family selection; environmental shock and manipulation-creative selection techniques; selection in aquaculture; national breeding programmes; unintentional selection; correlated responses to...

This article discusses the application and principle of polyploidy; polyploid induction in fish; polyploid induction in shellfish; triploid cells; ploidy determination; triploid fish performance; invertebrate triploid performance; tetraploids; hexaploid fish; tetraploid shellfish; fisheries...

In this chapter, the genetic variation, interspecific hybridization, interactions, population structure and biodiversity as well as the effects of geography and environment on the population variation of hatchery and wild fish were discussed. The factors affecting the establishment of new genotypes ...

This chapter covers the applications of genomics, gene mapping, quantitative trait locus mapping and marker-assisted selection in aquaculture, particularly fish culture. Focus is given on basic genomics, genetic maps, choice of markers, mapping systems, linkage disequilibrium, isozyme maps, DNA...
