“…These are in line with results obtained by Dinh and Nguyen (2014), Dinh et al (2013), Kitcharoen et al (2012) and Thanh et al (2010) for the same species (Dinh & Nguyen 2014). However, higher results were evidenced by Nugroho et al (2005) showing h 2 estimates as high as 0.84 for body weight and lower estimates as compared to this study were also reported by Luan et al (2012) and Sun et al (2013).…”

“…vannamei using ST and SS 50 were 0.154 4±0.044 6 and 0.147 5±0.040 0, respectively. Those are much lower than the values of TSV resistance in this species (0.28±0.14), tolerance to low-oxygen (0.23) and low-pH (0.23) in Larimichthys crocea (Argue et al, 2002;Wang et al, (Charo-Karisa et al, 2005;Liu et al, 2011;Kong et al, 2012).The common environment eff ect was omitted from the generalized linear mixed model in the present study, because the juveniles were with extremely short communal rearing period and lack of gene ties (only 25 half-sib families in 52 full-sib families), which may have contributed to the fact that the common environment variances could not be partitioned eff ectively (Gitterle et al, 2005a, b;Krishna et al, 2011;Luan et al, 2012). Thus, the heritability estimates might be overestimated with a confounding eff ect between the additive and nonadditive genetic and maternal eff ects included in the c 2 eff ect (Pante et al, 2002;Rutten et al, 2005;Castillo-Juárez et al, 2007;Nguyen et al, 2007).…”

“…Several selective breeding programs are being developed in L . vannamei , and both ANOVA (analysis of variance) and restricted maximum likelihood (REML) methods have been used to estimate the heritability for growth-related, survival, reproduction, resistance to Taura syndrome virus (TSV), resistance to white spot syndrome virus (WSSV) and resistance to hypoxia traits in them (Goyard et al, 1999;Argue et al, 2002;Pérez-Rostro and Ibarra, 2003a, b;Gitterle et al, 2005a, b;CastilloJuárez et al, 2007;Ibarra et al, 2007;Ibarra et al, 2009;Luan et al, 2012).

A bstractAmmonia, toxic to aquaculture organisms, represents a potential problem in aquaculture systems, and the situation is exacerbated in closed and intensive shrimp farming operations, expecially for Litopenaeus vannamei . Assessing the potential for the genetic improvement of resistance to ammonia in L . vannamei requires knowledge of the genetic parameters of this trait. The heritability of resistance to ammonia was estimated using two descriptors in the present study: the survival time (ST) and the survival status at half lethal time (SS 50 ) for each individual under high ammonia challenge. The heritability of ST and SS 50 were low (0.154 4±0.044 6 and 0.147 5±0.040 0, respectively), but they were both signifi cantly diff erent from zero ( P <0.01). Moreover, these two estimates were basically the same and showed no signifi cant diff erences from each other ( P >0.05), suggesting that ST and SS 50 could be used as suitable indicators for resistance to ammonia. There were also positive phenotypic and genetic correlation between resistance to ammonia and body weight, which means that resistance to ammonia can be enhanced by the improvement of husbandry practices that increase the body weight. The results from the present study suggest that the selection for higher body weight does not have any negative consequences for resistance to ammonia. In addition to quantitative genetics, tools from molecular genetics can be applied to selective breeding programs to improve the effi ciency of selection for traits with low heritability.

In the present study, the coefficient of variation for harvest body weight of L. vannamei ranged from 14.31% to 36.59%, which has provided important precondition and foundation for improving its growth performance by cross‐breeding and selective breeding.…”

The aim of this study was to estimate heterosis and heritability for harvest body weight of the Pacific white shrimp (Litopenaeus vannamei) measured at commercial farm conditions. Heterosis and heritability were estimated using a base population from diallel crosses of eight introduced strains. The base population included 9936 shrimp from 207 families that were produced with 188 sires and 172 dams using a nested mating design by artificial insemination. Heterosis was calculated basing on the least squares means (LSM) of harvest body weight. The results showed that most of the hybrids (75%) have positive heterosis for harvest body weight, which ranged from À13.36% (UA2 9 UA5) to 13.80% (UA6 9 UA5) with a mean of 2.41%. The high amount of heterosis manifested in the hybrids indicated the usefulness of these hybrids for improving the growth. Variance components and heritability for harvest body weight were estimated using an animal model. The heritability estimate for harvest body weight was 0.092 AE 0.082 (h 2 ) when genetic groups were excluded from the pedigree, but it was decreased when genetic groups were included in the pedigree (h 2 group = 0.066 AE 0.050), implying that there are strain additive genetic effect and heterosis in the base population. However, the heritability estimates for harvest body weight were significantly different from zero (P < 0.05) and there was no significant difference between h 2 and h 2 group (P > 0.05). The results from this study indicated that significant improvement for growth is possible through crossbreeding and selective breeding in L. vannamei.
