“…Moreover, increased environmental variability can result in low estimates of heritability even in the presence of significant genetic variation (Merilä & Sheldon, 1999). In spite of the importance of survival and reproductive traits, the implementation of selection for these traits in shrimp breeding programmes is limited (Ibarra, Pérez-Rostro, Ramírez, & Ortega-Estrada, 2007;Ibarra, Racotta, Arcos, & Palacios, 2007). Despite the limitations and difficulty in measurement and low heritability, their high economic importance warrants further investigation on how they can best be incorporated in selective breeding programmes.…”

Genetic parameters of growth, reproductive efficiency and survival are important for designing successful genetic improvement programmes. In this study, a database was assembled and a meta-analysis was conducted using 87 peer-reviewed published studies on genetic parameters of 63 economically important traits reported across nine major farmed shrimp species. A total of 641 estimates of heritability, 978 estimates of genetic correlations and 658 estimates of phenotypic correlations were included in this study. Pacific white shrimp (Penaeus vannamei) was the most widely reported species followed by giant freshwater prawn (Marcobrachium rosenbergii) and black tiger prawn (Penaeus monodon). Published studies demonstrate large variability across heritability and correlation estimates. Consensus estimates were based on both unweighted and weighted averages. The traits were broadly classed into weight, morphology, growth rate, body composition, feeding efficiency, reproductive efficiency and survival. This meta-analysis revealed moderate-to-high heritability estimates for weight (0.30 ± 0.002), morphological (0.26 ± 0.003), growth rate (0.27 ± 0.01) and feeding efficiency (0.58 ± 0.07) traits, but low for body composition (0.06 ± 0.009), reproductive efficiency (0.11 ± 0.006) and survival traits (0.15 ± 0.003). Strong responses to selection were found among the shrimp species studied. We have developed a ShinyApp (https://khatk ar.shiny apps.io/shrimp_genet ics/) for visualization of the individual heritability estimates. In addition to the metaanalysis of genetic parameters, we have calculated the correlated responses among economically important traits and highlighted response to selection, realized heritability, social interaction and common environmental effects in shrimp breeding programmes in terms of industry implications. Consensus estimates suggest that there is sufficient additive genetic variation to carry out effective genetic improvement programmes in these species.

“…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.

“…The existence of established breeding programmes has provided the means of assessing a wider range of traits to guide breeding and to avoid the deleterious consequences of uncontrolled inbreeding. Estimates for heritability in growth are now published for P. vannamei Argue et al 2002;Pérez-Rostro & Ibarra 2003a,b;Gitterle et al 2005a,b;Castillo-Juarez et al 2007;Ibarra & Famula 2008), P. monodon Kenway et al 2006) and P. japonicus (Hetzel et al 2000); for heritability in reproductive traits in P. vannamei (Arcos et al 2004;Ibarra et al 2007a) and P. monodon (Macbeth et al 2007), for heritability in hypoxia in P. vannamei (Ibarra et al 2007a) and for heritability in disease in P. vannamei (Argue et al 2002;Gitterle et al 2005b). The relationship between growth measures and measures of disease resistance has been estimated in P. vannamei by Argue et al (2002) and Gitterle et al (2005b).…”

Penaeus (Litopenaeus) vannamei Boone, 1931 and Penaeus monodon Fabricius, 1798 provide 87% of the world’s farmed marine shrimp, and 99% with another five species, Penaeus (Fenneropenaeus) chinensis (Osbeck, 1765), Penaeus (Fenneropenaeus) indicus Milne‐Edwards, 1837, Penaeus (Fenneropenaeus) merguiensis de Man, 1888, Penaeus (Litopenaeus) stylirostris Stimpson, 1874 and Penaeus (Marsupenaeus) japonicus Bate, 1888. Genetically improved strains have been traded for P. chinensis, P. stylirostris, P. vannamei and P. monodon, although closed populations have been developed for all seven species. To date, domesticated strains have played a dominant role in seed production for only P. vannamei and P. stylirostris. Extensive worldwide transfer of wild and/or domesticated stocks has occurred for these two species and for P. monodon, but the volume and extent of transfer of the other species is less. Genetic variation documented in wild stocks does not appear to be threatened, but variation within cultured stocks is often reduced relative to the wild and has affected performance in some (now mostly defunct) cultured populations. Hybridization is not effective in producing useful shrimp strains. There is no organized banking of penaeid shrimp genetic resources, either as live shrimp, frozen tissue, tissue or cell culture or DNA. Open access DNA sequences are available, although limited for most species. Significant expressed sequence tags and large insert libraries are available only for P. vannamei and P. monodon.
