“…For the traits studied, genetic correlations (0.921-0.969) were higher than phenotypic correlations (0.711-0.748). There are signifi cant genetic correlations among studied traits, which accord with other studies estimating signifi cant positive and high genetic correlations between growth traits (Hung et al, 2013;Trọng et al, 2013;Whatmore et al, 2013).…”

“…The correlation coeffi cients of estimated breeding values and phenotypic values of the studied traits ranged from 0.506 to 0.524, which were lower than those reported by Zhang et al (2011) on body mass of shrimp Fenneropenaeus chinensis (0.732-0.907). This was mainly because of the small number of testing families (only 22 families), unsatisfactory data structure (just full-sib families) and insuffi cient depth of the pedigree (only single generation), as reported by Whatmore et al (2013), and the low trait heritabilities obtained in this study. Therefore, for estimating genetic parameters accurately, it is essential to include a good depth in the pedigree and ideal data structure in the experimental design.…”

A bstractPhenotypic and genetic parameters for growth-related traits in the half-smooth tongue sole, Cynoglossus semilaevis , were estimated in 22 full-sib families produced by normal and neo-male breeding stocks. As phenotypic males with female genotypes, neo-males are harmful in C. semilaevis aquaculture because they reduce overall production. The present study evaluated the difference in the growth-related traits: total length (TL), body weight (BW) and square root of body weight (SQ_BW) at the age of 570 days between normal and neo-male offspring (neo-males used as male parents). The difference in the proportion of females between normal and neo-male offspring was also assessed. Based on the linear mixed model, restricted maximum likelihood (REML) and best linear unbiased prediction (BLUP) were used to estimate various (co)variance components and estimated breeding values (EBVs) of growth-related traits. As a result, all the mean values of the three studied traits were signifi cantly larger in normal offspring than in neo-male offspring. Additionally, the female proportion was signifi cantly larger in normal offspring than in neo-male offspring. Heritability was 0.128±0.066 2 for TL, 0.128±0.065 5 for BW and 0.132±0.062 9 for SQ_BW, all of which were low level heritabilities. The correlation coeffi cients of EBVs and phenotypic values of the target traits were 0.516 for TL, 0.524 for BW and 0.506 for SQ_BW, all of which were highly signifi cant ( P <0.01). Genetic correlations among TL, BW and SQ_BW were positive high (0.921-0.969) and higher than those of phenotype (0.711-0.748), both of which had low standard errors (0.063-0.123 for genotype, and 0.010-0.018 for phenotype). Compared with normal offspring, neo-male offspring have lower breeding values for each studied trait through EBVs comparison. Therefore, neo-male offspring should not be used as broodstock in a C. semilaevis breeding programs.

“…The heritability estimates in the present study ranged from 0.12 to 0.37 which is comparable to those reported by Navarro et al (2009). Whatmore et al (2013) for body and carcass traits in Seriola lalandi (0.15 to 0.30). Gjerde et al (2012) estimated the heritability of body weight in Oreochromis niloticus (0.19±0.04), which was higher than thepresent estimate at 720 days of age (0.12) but lower than those for the other three ages (0.22 -0.37) obtained in the present study.…”

Estimation of genetic parameters for growth related traits at different stages of development in Paralichthys olivaceus (Temminck & Schlegel, 1846)

Genetic parameters of growth traits at different growing stages of Paralichthys olivaceus (Temminck and Schlegel, 1846) were estimated using 30 families. The estimates of heritability for body weight at four developmental stages viz., 210, 450, 720 and 830 days of age, varied from 0.12 to 0.37. The heritability at 720 days of age was the lowest and that of 450 days was the highest. The maternal effect was 0.08 at 210 days, 0.03 at 450 days and almost zero (8.89 E-8 and 2.40 E-7) at 720 and 830 days. Correlation coefficients of the estimated breeding value (EBV) and phenotypic value (PV) of body weight at different developmental stages were 0.470 -0.803, which were highly significant (p<0.01). Correlation of estimated breeding value (EBV) and phenotypic value (PV) was the highest at 210 days of age and the lowest at 720 days. Genetic correlation among the four stages showed large variation (0.339-0.811), which were highly significant except that of 210 and 830 days. The value and accuracy of estimating genetic parameters for growth traits at different stages was different. Therefore, the growth stage should be taken into account when designing a breeding program for growth traits in P. olivaceus.

“…Tagged individuals from the families are now undergoing growth performance analysis as the initial phase of their evaluation and eventual selection as broodstock. The prospects for genetic selection are good and a moderate to high heritability for growth is expected based on the results for Australian kingfish (Whatmore et al 2013). …”

Genetic improvement of New Zealand aquaculture species: programmes, progress and prospects

Aquaculture, like terrestrial farming, cannot achieve economic and sustainable production without high performing genetic stocks tailored to the conditions under which they are grown. It is essential, therefore, that aquaculture investment includes genetics and biotechnology to adapt marine livestock to the novel conditions of intensive aquaculture and to the demanding markets into which they are sold. The return on investment in well-structured breeding programmes can be very high, and significant performance and economic gains have been demonstrated in multiple species. Many factors must be considered in designing a genetic improvement programme, including the reproductive biology of the species and the identification of realistic and commercially relevant breeding goals based on the resources and facilities available. This paper reviews the options available to aquaculturists and provides examples of how these are being applied to six aquaculture species in New Zealand: king salmon, hāpuku, kingfish, Greenshell TM mussels, Pacific oysters and pāua (abalone).
