“…These values indicate heritability ranges from medium to high, highlighting the genetic basis of these stress tolerance traits. These findings are somewhat parallel to those documented by Wang [11] for stress traits involving high ammonia-N, low pH, and high salt tolerance in Penaeus vannamei (0.21 ± 0.06), and by Wang [9] for traits like low salt, low dissolved oxygen, and low pH tolerance in Larimichthys crocea (0.23, 0.10, and 0.23). Variations in heritability estimates across different studies can result from several factors, including the species being analyzed, the diversity in age and sex of the subjects, differences in growth conditions, and the use of various analytical models for evaluating the data.…”

“…Jiang [10] estimated the genetic parameters for growth and low salt tolerance in Haliotis diversicolor supertexta, finding a heritability of 0.06 ± 0.02 for the latter trait. Furthermore, Wang [11] evaluated genetic parameters for growth and combined stress tolerance in L. vannamei, showing that these traits possess high and intermediate levels of heritability, respectively, suggesting that improvements in growth traits could indirectly benefit combined stress tolerance. The influence of genetic and environmental factors on phenotypic traits [12] underscores the importance of breeding new L. vannamei varieties with enhanced stress tolerance for the health and sustainable development of the shrimp industry.…”

Litopenaeus vannamei stands out globally in aquaculture for its fast growth, broad salt tolerance, disease resistance, and high protein levels. Selective breeding requires the precise estimation of the variance components and genetic parameters for important traits. This study formed lineages from 20 full sibling families of L. vannamei, with progenitors from Thailand and the USA. We then assessed the genetic resilience traits of juvenile shrimp from these families to high ammonia-N, high pH, and low salinity by performing a 96 h acute toxicity test. Mortality rates for the families under 96 h exposure to high ammonia-N, high pH, and low salinity were 19.52–92.22%, 23.33–92.22%, and 19.33–80.00%, respectively, showing significant variance in stress tolerance among families (p < 0.05). Survival heritability estimates, using threshold male and female models, were 0.44 ± 0.12 in high ammonia-N, 0.41 ± 0.12 in high pH, and 0.27 ± 0.08 in low salinity, respectively. Genetic correlations between growth and stress resistance traits varied from 0.0137 ± 0.2406 to 0.8327 ± 0.0781, and phenotypic correlations ranged from 0.0019 ± 0.0590 to 0.6959 ± 0.0107, indicating a low-to-high positive correlation significant at (p < 0.05). It was found that the survival rate of families No. 2 and No. 9 was higher under high ammonia-N and high pH stresses, while the survival rate of family No. 10 was higher under low salinity stress after comparing two selection criteria, the breeding values and phenotypic values. Thus, these three families are identified as potential breeding program candidates. Through the creation of a genetic parameter estimation model, the genetic variances across mating combinations for stress resistance traits were obtained and families with heightened stress resistance were identified, laying the groundwork for enhanced genetic selection of L. vannamei.

“…This research used L. vannamei shrimp obtained from 36 full-sib families, which were produced at the Zhanjiang Guoxing Aquatic Technology Co., Ltd. (Zhanjiang, China), following the same methods as described previously [28]. To determine ammonia-N tolerance, an acute ammonia-N stress test following a logarithmic spacing of concentration (20, 26.3, 34.7, 45.7, 60.3 mg/L) was conducted with juveniles from 36 families.…”

Ammonia nitrogen is one of the main toxic substances in aquatic cultivation environments. Chronic exposure to excessive amounts of ammonia-N creates toxic consequences, retarding the growth of aquatic organisms. This study investigated the growth performance, morphological and physiological alterations, and transcriptome changes in the hepatopancreas and gills of white shrimp Litopenaeus vannamei. The results showed that there was no significant difference in the survival rate (p > 0.05), whereas growth performance was reduced significantly in the treated groups compared to the control groups (p < 0.05). Significant structural damage and vacuolation occurred in hepatopancreas and gill tissues in the treated groups. Superoxide dismutase (SOD) activity and Na+/K+-ATPase content were significantly increased by chronic ammonia-N exposure in the two tissue groups. In addition, catalase (CAT) activity and malondialdehyde (MDA) levels were significantly altered in the hepatopancreas groups (p < 0.05), whereas no differences were observed in the gill groups (p > 0.05). There were 890 and 1572 differentially expressed genes identified in the hepatopancreas (treated versus control groups) and gills (treated versus control groups), respectively, of L. vannamei under chronic ammonia-N exposure. Functional enrichment analysis revealed associations with oxidative stress, protein synthesis, lipid metabolism, and different serine proteases. The gills maintained cellular homeostasis mainly through high expression of cytoskeleton and transcription genes, whereas the hepatopancreas down-regulated related genes in the ribosome, proteasome, and spliceosome pathways. These genes and pathways are important in the biosynthesis and transformation of living organisms. In addition, both tissues maintained organismal growth primarily through lipid metabolism, which may serve as an effective strategy for ammonia-N resistance in L. vannamei. These results provided a new perspective in understanding the mechanisms of ammonia-N resistance in crustaceans.

“…Acute salinity stress has been shown to affect the growth and survival rate of L. vannamei larvae in previous studies. Pan (Pan et al, 2007) reported these findings; Lin (Lin et al, 2010) compared the tolerance of different families of L. vannamei to freshwater and obtained the basic population of excellent freshwater tolerant families; and Wang (Wang et al, 2022) discovered that both growth and comprehensive stress tolerance traits can be genetically improved through breeding, and growth traits can also be manipulated. This study aims to evaluate the stress tolerance of the breeding population, access the mortality rates of two introduced self-bred and hybrid families of L. vannamei under 96 h of high ammonia-N, high pH, and low salt stress, provide candidate materials for further family selection, and provide reference data for stress resistance breeding of L. vannamei.…”

In recent years, as the marine environment has been deteriorated, the aquaculture water environment has also been negatively affected to varying degrees. Negative environmental factors make extremely damaging to organisms, resulting in stress-induced diseases and high mortality rates of cultured shrimp. Therefore, stress resistance breeding of Litopenaeus vannamei and evaluating the stress tolerance of the breeding population are urgently needed now. Litopenaeus vannamei collected from Thailand (T) and the United States (M) were used as parents, while four progeny populations of TT, MM, TM, and MT were constructed by diallel cross, with a total of 20 families. The tolerance of young shrimp to high ammonia-N, high pH, and low salt was compared through a 96-h acute toxicity test; the heterosis of each mating combination was analyzed; and the tolerance of parents and offspring was evaluated. Here we show that under 96 h of high ammonia-N, high pH, and low salt stress, the mortality rates of each family were 19.52%–92.22%, 23.33%–92.22%, and 19.33%–80.00%, respectively. There were significant differences in the tolerance of different families to ammonia-N, pH, and salinity stress (P < 0.05). The population with a female parent from the United States had stronger tolerance to ammonia-N, pH, and low salt stress than the population with a female parent from Thailand. The population with a male parent from Thailand had weaker tolerance to pH and low salt stress than the population with a male parent from the United States, but it was superior to the population with a male parent from the United States under ammonia-N stress. The heterosis rates of the hybrid population TM in acute high ammonia-N, high pH and low salinity were 81.67%, 44.58% and −10.13%, respectively; However, the heterosis rates of the MT population were 14.89%, 38.89%, and −8.96%, respectively. The overall resistance of the four populations showed MM > MT > TT > TM. The population TM had obvious heterosis in high ammonia-N and high pH tolerance traits, and the family MM7 had a strong low salt tolerance, so it can be considered a candidate family for subsequent breeding work. Moreover, variability in stress resistance and heterosis of stress resistance of different populations obtained by family selection was discussed in this paper. The experimental results provide a basis for screening new strains of vannamei shrimp with strong stress resistance through family breeding.
