“…In this study, the heritability estimates (Cardellino and Rovira 1987) of growth traits at different ages were 0.256 ± 0.119 to 0.441 ± 0.124. The results are consistent with heritability estimates in prior studies (Hernandez-Ruiz et al 2020;Perez-Rostro and Ibarra 2003;Sui et al 2016) and our previous studies (Yuan et al 2018;Zhang et al 2017a, b) but lower than those reported by others (Andriantahina et al 2012;Ren et al 2020;Tan et al 2019). The difference might be caused by genetic or environmental factors, such as use of different populations, growth conditions, ages, sexes, and models (Elvingson and Johansson 1993;Korkeila et al 1991;Lu et al 2016;Montaldo et al 2013;Zhang et al 2017a).…”

“…Therefore, we evaluated the genetic parameters of L. vannamei tolerance to multiple-stress (simultaneous stress of high salt, low pH and high ammonia nitrogen). The heritability values of multiple-stress tolerance at 7 and 15 weeks were 0.029 ± 0.034 and 0.053 ± 0.058, respectively, similar to those of resistance to infectious hypodermal and hematopoietic necrosis virus (IHHNV) (0.08 ± 0.11) (Hernandez-Ruiz et al 2020), low-temperature tolerance (0.1094 ± 0.0265 and 0.0598 ± 0.0229) (Li et al 2015), and low dissolved oxygen tolerance (week 7, h 2 = 0.07 ± 0.04; week 13, h 2 = 0.15 ± 0.07) in L. vannamei (Zhang et al 2017b). However, the values are lower than those estimated for resistance to White spot syndrome virus (WSSV), low dissolved oxygen, and high ammonia nitrogen (Ibarra et al 2007;Lillehammer et al 2020;Lu et al 2017).…”

“…There have been intensive studies on estimating the genetic parameters of the growth traits of L. vannamei. The estimated heritability of the growth traits of L. vannamei has been reported by several studies as 0.84 ± 0.43 (Argue et al 2002), 0.3191 ± 0.0622 (Li et al 2015), 0.11 ± 0.02 to 0.23 ± 0.05 (Zhang et al 2017b) and 0.24 ± 0.08 to 0.46 ± 0.09 (Zhang et al 2017a), among other studies (Caballero-Zamora et al 2015;Hernandez-Ruiz et al 2020;Li et al 2016;Rivero-Martinez et al 2021;Yuan et al 2018). However, the estimation of genetic parameters of breeding traits is affected by generation, population, growth traits, age, sex and analysis model (Castillo-Juarez et al 2007;Elvingson and Johansson 1993;Lu et al 2016;Luan et al 2012;Zhang et al 2017a).…”

The genetic parameters for growth and multiple-stress resistance in Litopenaeus vannamei at 7 and 15 weeks of age were estimated using sixty full-sib families (including 29 half-sib families) in the present study. The heritability of growth traits was estimated to be medium to high (0.256 ± 0.119 to 0.441 ± 0.124), and that of multiple-stress [simultaneous stress of high salt (35), low pH (6 ± 0.1) and high ammonia nitrogen (56 mg/L)] tolerance traits was low (0.029 ± 0.034 to 0.053 ± 0.058), suggesting the feasibility of selecting increasing growth traits and that genetic improvement of stress tolerance traits requires multi-generation breeding by family and intra-family selection. The genetic correlations of growth traits (body weight, total length, body length, carapace length, carapace width and abdominal length) at identical ages were high (0.855 ± 0.031 to 0.999 ± 0.0002) (P < 0.01). The highly significant correlations between growth traits showed that any growth trait could be replaced by other growth traits for indirect selection. The genetic correlations between growth traits and multiple-stress tolerance traits at identical ages were low, but the positive correlation (0.081 ± 0.129 to0.224 ± 0.125) indicated that selection of growth traits will have a positive correlation response to multiple-stress tolerance traits. There was a weak genetic positive correlation (0.285–0.342) (P < 0.05) in the growth traits between the two different age stages, however the genetic correlation in the multiple-stress tolerance traits between the two different age stages were low and not significant (P > 0.05).This suggests that selection for growth traits in L. vannamei at an early age may not be optimal and should be undertaken at later stages of growth.

“…Of these 16/30 had problems while 14/30 did not, indicating that IHHNV was not significantly associated with problem ponds and that other causes should have been sought but were not. In addition, publications from the interval 2010 to 2020 that describe lack of significant problems linked to IHHNV were not included in the AAHC review (e.g., Hernández-Ruíz et al, 2020; Mendoza-Cano et al, 2014).…”

The purpose of this study was to confirm evidence that the shrimp parvovirus IHHNV no longer has a significant negative economic impact on farmed shrimp production, and that it should be delisted as a pathogen by the World Organization for Animal Health (WOAH). Current published evidence for delisting is presented in the introduction, and experimental evidence is presented from 11 commercial ponds cultivating the giant tiger shrimpPenaeus monodonin Thailand. All 11 ponds gave positive PCR test results for IHHNV using 2 methods recommended for IHHNV diagnosis by WOAH. However, when an additional in-house “IHHNV Long-Amp method” (IHHNV-LA) was also used to amplify 90% of the 4 kb IHHNV genome sequence, only 4 of the 11 ponds gave positive PCR test results. Further tests using normal histopathological analysis for the presence of pathognomonic Cowdry A type inclusions (CAI),in situhybridization (ISH) and immunohistochemistry (IHC) could confirm IHHNV infections in only 2 of those 4 ponds. In addition, a positive detection of CAI alone was equivalent to ISH or IHC in confirming IHHNV infection after a positive test with any of the PCR methods used. In summary, the recommended WOAH PCR methods gave false positive test results for IHHNV infection with 9/11 ponds (82%). All 11 ponds gave profitable harvests despite the confirmation of IHHNV in 2 ponds, where it was accompanied by various additional pathogens, as were all 11 ponds. Unfortunately, according to current practice, positive PCR test results with the WOAH methods can lead to rejection of traded shrimp products without assurance that they are not false positive results arising from EVE. Our results, results from others and our analysis of a recent decision of WOAH to maintain IHHNV as a listed disease suggest that WOAH must reconsider IHHNV for de-listing.

The disease is a limiting factor and causes economic losses in the cultivation of white shrimp (Litopenaeus vannamei). Diseases in vaname shrimp are caused by viruses, microbes, parasites, organisms, and natural conditions. One of these diseases is infectious hypodermal and hematopoietic necrosis (IHHNV). This study was conducted from February to April 2022. This study aimed to analyze the prevalence of IHHNV that attacks white shrimp in the Bengkalis Regency and to observe and observe clinical symptoms in whitewashed shrimp infected with IHHNV in the pond area of the Bengkalis Regency. The research method used in this study is a survey method. The primary data taken included water quality observations, morphological observations, sampling, and detection of IHHNV using the polymerase chain reaction (PCR) method. The results showed that the prevalence of IHHNV in white shrimp was 0%. PCR testing using a specific primer measuring 392bp showed that white shrimp samples from three locations in Bengkalis District, namely Bengkalis District, Bukit Batu District, and Rupat District, were negative for IHHNV and did not show any clinical symptoms of IHHNV on morphological examination
