“…Maternal effect was present during the first two ages (0.08 and 0.03 respectively), whereas these effects were not discernible at the latter two growing stages, which were different from the value of maternal effect (0.07 -0.54) obtained by Liu et al (2011). This is as expected because as the fish grows, the maternal influence diminishes.…”

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.

“…In aquaculture production, the rate of growth is a critically important economic trait (Liu et al, 2011). The main objective of most selective breeding programs in fish is to enhance the growth rate, which can lead to more efficient fish production (Charo-Karisa et al, 2007).…”

“…In fish breeding, the genetic analysis of many quantitative traits was reported. Generally, these studies mostly utilized the data collected from one single time point to estimate the genetic effects (Gjerde et al, 1997;Martıńez et al, 1999;Shikano, 2007;Tian et al, 2011;Liu et al, 2011Liu et al, , 2013Zhang et al, 2014). However, the genetic mechanism of quantitative traits changes with temporal and spatial patterns (Zhu, 1995).…”

To elucidate the genetic mechanism of growth trait in Takifugu rubripes during ontogeny, developmental genetic analysis of body weight was conducted by mixed genetic model with additive-dominance effects, using complete diallel cross with three different strains of T. rubripes from Laizhou Shandong, Tangshan Hebei and Dalian Liaoning. Unconditional genetic analysis revealed that the unconditional dominance effects with very significant P<0.01 were detected during 8 to 20 months and the unconditional additive effects were detected only at 17 and 20 months. This suggests that the body weight trait was mainly controlled by dominance effects from 8 to 17 months and by both dominance and additive effects from 17 to 20 months. Conditional analysis showed that the net dominance effects were ascertained during growth from 0 to 8, 8 to 11, and 11 to 14 months, and the net additive effects were detected only during growth from 14 to 17 months. The following conclusions could be drawn from the results: the selection period should be considered during 14 to 17 months if the genetic improvement of T. rubripes is conducted using selective breeding, and the selection period should be considered during 8 to 14 months if cross breeding is used. The conditional genetic procedure is a useful method to elucidate the dynamics of genes action governing the variability of quantitative traits during ontogenetic development. In addition, the study is also highly important to determine the appropriate developmental period (t-1→t) for trait measurement in developmental quantitative genetic analysis in fish.

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.
