“…Regardless of the differences, it appears that heritability of body weight in P. vannamei is moderate or high, indicates a potentially significant response to selection. Our results was also higher than those reported previously: 0.24±0.05 and 0.17±0.04 for harvest weight in ponds and tanks, respectively, at 23 weeks (Gitterle et al 2005); 0.17±0.06 for weight through a restrictedmaximum likelihood method after at 29 weeks (Pérez-Rostro & Ibarra 2003b); from 0.09 to 0.11 for body weight in the presence of WSSV(White spot syndrome virus) at 19 weeks (Caballero-Zamora et al 2014), the probable reason were other research based on f introducing sex as fixed effects, the more acute heritability had produced by eliminating more fixed effects. So we will identification sex at suitable time in next research works.…”

Based on restricted maximum likelihood (REML) method under animal model, the genetic parameters in Litopenaeus vannamei for growth-related traits on body weight (BW, g), body length (BL, cm), abdominal segment length (ASL, cm), carapace length (CL, cm), and survival (SU) under conditions of 96 hours of ammonia exposure at 14 and 21 weeks of age were estimated, respectively. The heritability estimates for growth-related traits at different growth stages were moderate, ranging from 0.24±0.09 to 0.30±0.06 for 14-week-old shrimp and 0.26±0.07 to 0.31±0.06 for 21-week-old shrimp, respectively. The heritability estimates for survival under conditions of high Ammonia-N concentrations were 0.13±0.11 for 14-week-old shrimp and 0.17±0.08 for 21-week-old shrimp, respectively. Genetic correlations between growth-related traits within age cohorts were generally high (ranging from 0.74±0.06 to 0.89±0.16), but for growth-related traits between ages were low (ranging from 0.14±0.05 to 0.46±0.09); genetic correlations between growth-related traits and survival under conditions of high Ammonia-N concentrations were all positive (ranging from 0.25±0.03 to 0.32±0.05). Our results suggest that selection to improve any single body trait would likely produce correlated responses in the other traits examined and that selecting for growth will cause a positive correlated response in terms of Ammonia-N tolerance; estimates of genetic parameters for Ammonia-N tolerance should be calculated at a later age.

“…Gitterle, Ødegård, Gjerde, Rye, and Salte () estimated the heritability for resistance to WSD in L. vannamei as ranging from 0.01 to 0.21 using five different statistical models: two linear models, a threshold model, a Cox model, and a Weibull model; the first two models measured the survival probability, while the others measured the risk of death. Heritability for resistance to WSD was estimated by Caballero‐Zamora et al () to be 0.06 in a natural outbreak. In turn, Huang et al () and Trinh et al () showed that families with higher survival rates for WSD in experimental challenges or those selected for resistance had lower viral loads than families with lower survival rates, which indicates the presence of genetic variation for VL and a negative (favorable) genetic relationship between survival and viral load, similar to that found in this study.…”

Heritability and genetic correlations for body weight at harvest size (BW), grow-out survival (SU), and log-transformed infectious hypodermal and hematopoietic necrosis virus (IHHNV) load (VL ln ) in Litopenaeus vannamei were estimated. Data were obtained in 2012 from a shrimp breeding population in Mexico using 12,440 shrimp for BW and 16,814shrimp for SU, and quantitative polymerase chain reaction determinations from 160 full-sib families were obtained for VL ln . DNA was extracted from pooled muscle samples of six shrimp per family for a total of 960 individuals. Heritability estimates for BW, SU, and VL ln at the family mean and at individual levels were 0.24 ± 0.08, 0.02 ± 0.01, 0.42 ± 0.45, and 0.08 ± 0.11, respectively. Genetic correlation estimates of BW with SU, BW with VL ln , and VL ln with SU were 0.40, −0.04, and −0.57, respectively. Our results suggest that VL ln has genetic variation and a favorable genetic association with BW † Deceased.

“…Also, genetic relationships between growth related traits and WSSV resistance are reported to vary with growth or infection stages. Caballero-Zamora et al (2015) obtained a positive genetic correlation between the two traits at post-larval stage 10, whereas the correlation estimate was negative in a later stage of growth development (Gitterle et al, 2005; Campos-Montes et al, 2013). Knowledge on genetic variation in WSSV resistance and its relationship with body weight at different stages of growth development will provide basic information to develop genetic measures to improve commercial traits in the future breeding selection programmes for this species.…”

“…Estimations of heritability for WSSV resistance in these studies were based on laboratory challenge test experiments or on mortality loss recorded after natural outbreaks during a grow-out phase in farms (Gitterle et al, 2005, 2006b; Caballero-Zamora et al, 2015; Sui et al, 2016). To date, there is, however, no published information regarding genetic parameter estimates for WSSV resistance at different times of infection in juvenile Whiteleg shrimp.…”

Genetic Variation in Disease Resistance Against White Spot Syndrome Virus (WSSV) in Liptopenaeus vannamei

White Spot Syndrome Virus (WSSV) is the most damaging pathogen in terms of production and economic losses for the shrimp sector world-wide. Estimation of heritability for WSSV resistance was made in this study to obtain necessary parameter inputs for broadening the breeding objectives of an ongoing selective breeding programme for Whiteleg shrimp ( Liptopenaeus vannamei ) that has focussed exclusively on improving growth performance since 2014. The present study involved a disease challenge test experiment using a total of 15,000 shrimps from 150 full- and half-sib families (100 individuals per family). Survival rates were recorded at six different experimental periods: 1–3 days (S1), 1–5 days (S2), 1–7 days (S3), 1–9 days (S4), 1–12 days (S5), and 1–15 days (S6) and were used as measures of WSSV resistance. There was significant variation in WSSV resistance among families studied. Quantitative-real time PCR (qPCR) analysis showed that the amount of viral titer (viral load) was significantly lower in high than low resistance families. Analyses of heritability were carried out using linear mixed model (LMM) and threshold logistic generalized model (TLGM). Both linear and threshold models used showed that the heritability (h 2 ) for WSSV resistance was moderate in the early infection phases (S1–S4), whilst a low h 2 value was observed for survival after 12 and 15 days of the challenge test (S5 and S6). The transformed heritabilities for WSSV resistance ranged from 1 to 31% which were somewhat lower than those estimated on the liability scale. Genetic correlations between survival rates measured over six different days post-infection were high and positive (0.82–0.99). The phenotypic correlations ranged from 0.31 ± 0.01 to 0.97 ± 0.01. The genetic correlations between body weights and WSSV resistance were negative. Our results on the heritability and genetic correlations show that improvement of WSSV resistance can be achieved through selective breeding in this population of Whiteleg shrimp.
