“…When the narrow sense heritability is low, but the non-additive variation or dominance effect is high, heterosis can be easily achieved by crossbreeding. It is reported that selective breeding was not efficient for genetic improvement of the growth rate in the common carp, but genetic improvement by crossbreeding was easily obtained (Moav and Wohlfarth, 1976;Ankorion et al, 1992;Wohlfarth, 1993;Bakos and Gorda, 1995;Hulata, 1995;Vandeputte, 2003). Meanwhile, significant heterosis in the common carp has also been obtained by crossbreeding in China.…”

The common carp (Cyrpinus carpio L.) is the oldest cultured and the most domesticated fish species, as well as one of the most important freshwater fishes in the world. However, scientific studies on evaluating the growth-related quantitative traits in this fish are limited. Heritability, the most important parameter in selective breeding programs, was extensively studied for the growth-related traits. The values varied widely among the experiments and methods used because of the existence of common environmental, dominance and maternal effects. However, correlations in phenotypic and genetic levels first evaluated several years ago were limited. On the other hand, heterosis was widely reported and easily obtained for growth-related traits in the common carp. Meanwhile, genotype environment interaction and prediction of breeding values have been studied recently, and are very important in conducting selective breeding programs. The developmental quantitative genetics of growth-related traits was first analyzed in the common carp for reasonable selection during ontogeny. It is expected that genetic improvement will be achieved by carrying out direct selective breeding in the common carp.

“…The preferential use of a cumulative response from selection instead of crossbreeding programs is primarily due to the low level of expressed heterosis, possible effects of the genotype on non-additive genetic performance via environmental interactions and the dependence on a specialized hatchery for producing hybrid fingerlings in each cycle (Gjerde and Refstie, 1984;Bentsen et al, 1998). In contrast, hybrid crosses have been demonstrated to perform better than pure lines in some instances, e.g., the common carp, Cyprinus carpio (Bakos and Gorda, 1995;Hulata, 1995), and hybrid crossing was shown to be successful in breeding programs in carp (Wohlfarth et al, 1980;Kirpichnikov, 1981;Wohlfarth, 1993) and tilapia (Circa et al, 1994).…”

“…In a successful long-term program based on genetic selection and hybridisation for the development of inbred pure lines of carp in Hungary (Bakos, 1979;Bakos & Gorda, 1995), the use of such a technique resulted in very productive hybrids (Nagy et aI., 1979). Although the first gynogenetic individuals produced in a line typically perform rather poorly due to inbreeding effects, in trout they can be hormonally sex-reversed to functional males that produce only Xbearing sperm.…”

Biotechnology can currently be considered of importance in aquaculture. The increase in the production of aquatic organisms over the last two decades through the use of biotechnology indicates that in a few generations biotechnology may overtake conventional techniques, at least for the commercially more valuable species. In the last few years, genetics has contributed greatly to fish culture through the application of the more recent techniques developed in biotechnology and in genetic engineering. At present, the most commonly used methods in fish biotechnology are chromosome manipulation and hormonal treatments, which can be used to produce triploid, tetraploid, haploid, gynogenetic and androgenetic fish. These result in the production of individuals and lineages of sterile, monosex or highly endogamic fish. The use of such strategies in fish culture has as a practical objective the control of precocious sexual maturation in certain species; other uses are the production of larger specimens by control of the reproductive process and the attainment of monosex lines containing only those individuals of greater commercial value. The use of new technologies, such as those involved in gene transfer in many species, can result in modified individuals of great interest to aquaculturists and play important roles in specific programmes of fish production in the near future.
