“…About BW proportion of phenotypic variance due to the effects common to full-sibs, they were estimated as 0.12 ± 0.04 and 0.15 ± 0.03 for P10 and P30, respectively. These values are in agreement with the findings of other authors (Gitterle et al, 2005b) and with previous studies in this population (Campos-Montes et al, 2013;Castillo-Juárez et al, 2007).…”

“…Body weight heritability in P10 and P30 is in agreement with the findings of Gitterle et al (2005b) and Castillo-Juárez et al (2007), who observed no differences between environment estimates. Heritability estimated for BW in K15 from linear model betweenponds analysis was similar to that estimated with the bivariate within-pond linear model.…”

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.
