Summary: In this study, we investigated the effect of salinity on post-larval shrimp growth and found that increasing salinity had both over-compensation and full-compensation effects on body length and weight. The activities of digestive enzymes and osmoregulation enzymes were affected by salinity restriction and compensation stages. The mechanistic target of the rapamycin signaling pathway may play a role in regulating growth in response to salinity changes. Additionally, we observed that shrimp cultured at a salinity of 30 ppt showed the highest resistance to Vibrio parahaemolyticus infection. Therefore, adjusting the culture salinity can improve disease resistance and uniformity in shrimp.

Summary: This study investigated the effects of different ultrasonic pretreatments on the gel properties of shrimp surimi. The results showed that proper ultrasound treatment could improve the gel properties by expanding the protein and exposing more functional groups. The study provides a new technical means to improve the gel properties of shrimp surimi.

Summary: This study investigates the differences in gene expression between tolerant and susceptible families of Pacific white shrimp Litopenaeus vannamei under normal and high-salinity conditions. Results suggest that crustacyanins and serine proteases play important roles in shrimp tolerance to high salinity. The findings provide valuable information for understanding the mechanism of high-salinity tolerance and could contribute to the breeding of shrimp varieties with improved tolerance.

Summary: This study evaluated the stress resistance of Litopenaeus vannamei through family breeding and compared the tolerance of different families to high ammonia-N, high pH, and low salt stress. The population with a female parent from the United States showed stronger tolerance to stress compared to the population with a female parent from Thailand. The TM hybrid population exhibited heterosis in high ammonia-N and high pH tolerance, while family MM7 had strong low salt tolerance.

Summary: Beta-glucan was found to significantly enhance the antioxidant capacity of Litopenaeus vannamei. Under low salinity conditions, a dietary level of 0.2% beta-glucan was determined to be optimal, promoting improved growth performance, increased digestive enzyme activity, and enhanced antioxidant and immune capacities. Furthermore, beta-glucan positively influenced the intestinal microbiota and activated relevant metabolic pathways. This study provides practical insights for enhancing disease resistance in aquaculture.

Summary: This study identified and characterized three types of AQPs in Litopenaeus vannamei and investigated their potential roles in osmoregulation. The expression levels of AQPs were significantly decreased under salinity stress, though the patterns varied among isoforms and tissues. Comparative transcriptome analysis revealed the involvement of aquaglyceroporin and amino acid metabolism related genes and pathways in the response to acute salinity changes in the intestine.

Summary: The ionic profile of inland low salinity water sources can vary significantly, specifically in terms of magnesium (Mg2+) concentrations. In inland shrimp farming in Alabama, USA, magnesium supplementation is commonly used to reach concentrations >20 mg/L at 1 to 11 g/L salinities. However, higher concentrations may be needed for larger shrimp in the later phases of production. Two field trials were conducted to evaluate the effects of Mg2+ concentration in low salinity water on the growth and physiology of Pacific white shrimp.

Summary: This study compared the antioxidant capacity and immune response between a low salt tolerant hybrid and a normal variety of shrimp cultured at different salinities. The results showed that the hybrid population had lower apoptotic cell numbers and reactive oxygen content, as well as stronger antioxidant enzyme activities and higher immune-related enzyme activities and gene expression levels compared to the control group under low salinity conditions. These findings provide a foundation for the selection and breeding of low-salt tolerant, high-quality Pacific white shrimp.

Summary: This study evaluated the genetic parameters and genomic prediction accuracy of high salinity tolerance traits in Pacific white shrimp and found that genomic selection is superior to traditional selection methods. The high salinity tolerance traits of shrimp have medium to high heritabilities, providing important guidance for genomic selection of shrimp tolerant to high salinity.

Summary: The study evaluated the effects of different concentrations of chitosan supplementation from shrimp tailings on the antioxidant and immune systems of Litopenaeus vannamei in a BFT system, finding that dietary intake of chitosan could enhance antioxidant defenses, with at least 1 g kg(-1) chitosan showing potential to improve defense mechanisms and stress resistance in aquaculture.

Summary: The study found that dietary yeast hydrolysate improved the defense against low salinity stress in Pacific white shrimp by modulating the activity of Na/K-ATPase, PO and SOD enzymes. The impact of diet factor on AKP and ACP activities of the organism was less compared with the culture salinity.

Summary: This study evaluated the accumulation, mass balances, and potential health risks of Hg in basil cultivated simultaneously with shrimp in an aquaponic system. The results showed that the aquaponic treatments did not significantly affect Hg accumulation, and the Hg concentrations in basil tissues were below the international guidelines. Mass balances revealed that most Hg entered the system through input water and was mainly eliminated through zeolite. The inorganic speciation of Hg differed slightly between treatments, but the health risk index indicated that the consumption of basil grown with shrimp would not pose a risk to the population.

Summary: The study demonstrates that decreasing magnesium levels in low-salinity water negatively impact the growth, survival, and stress response of Pacific white shrimp, leading to reduced performance and increased feed conversion ratio. Magnesium plays a crucial role in the growth and osmoregulation of shrimp in low-salinity environments.

Summary: The red archaea containing carotenoids were applied in aquaculture for the first time, showing positive effects on salinity tolerance and ammonia stress tolerance in Litopenaeus vannamei. The supplementation of Halorubrum may be linked to the antioxidative capacity of bacterioruberin, making it a high value feed additive in shrimp larviculture.
