Summary: Glycogen synthase kinase 3 (GSK3) is a highly conserved serine/threonine protein kinase that plays important roles in insulin, Wnt, and various signaling pathways. In this study, a GSK3 gene was identified in the Pacific white shrimp genome and found to be highly expressed in different developmental stages and premolting stages. Knockdown of LvGSK3 led to retarded body weight growth and altered expression of molting-related genes, highlighting its potential applications in shrimp growth.

Summary: This study aimed to evaluate the effects of replacing fishmeal with soybean and cottonseed protein concentrates, as well as dietary supplementation of bile acids, on the growth performance, immunity, molting, and intestinal health of Litopenaeus vannamei. The results showed that bile acid supplementation could enhance the expression of immune and molting-related genes, improve intestine health, and enhance the growth performance of shrimp fed a low fishmeal diet.

Summary: This study investigated the beneficial effects of mannan oligosaccharide (MOS) on Litopenaeus vannamei, finding that MOS improved growth performance, digestion ability, antioxidant capacity, and immunity of the shrimp. It also optimized intestinal microecology, reduced antibiotic resistance genes, and increased resistance to V. parahaemolyticus, especially at higher levels of supplementation.

Summary: This study investigated the effects of mannan oligosaccharides (MOS) on health, growth performance, fatty acids deposition, and serum and urine metabolites in Hu lambs. The results showed that MOS improved the digestibility of organic matter, crude protein, ether extract, calcium, and phosphorus, as well as the proportion of unsaturated fatty acids in lambs. MOS also reduced the diarrhea rate and the proportion of saturated fatty acids. In addition, MOS regulated the metabolites in serum and urine, which were correlated with nutrient digestibility and fatty acid composition.

Summary: The study found that dietary supplementation of Mannan oligosaccharides did not affect feed intake, body weight, average daily weight gain, ruminal short-chain fatty acids concentration, or hematological parameters in sheep. However, it improved the digestibility of certain nutrients and decreased ruminal ammonia concentration, particularly at a dose of 1.6%.

Summary: This study aimed to determine the dietary riboflavin requirement and its effects on the growth performance, feed utilization, innate immunity, and diet digestibility of Litopenaeus vannamei. The results showed that riboflavin significantly improved the growth performance, non-specific immunity, and intestinal morphology of the shrimp, with an optimal riboflavin requirement of approximately 40.9 mg/kg diet.

Summary: The commercial cultivation of Litopenaeus vannamei has greatly benefited the global shrimp industry in the past decade. However, there are no academic sources supporting its commercial farming in Bangladesh, which is an important player in the global shrimp industry. The declining shrimp industry in Bangladesh, caused by the low production of traditionally cultivated black tiger shrimp and its susceptibility to diseases, calls for immediate policy measures to introduce high-yielding Litopenaeus vannamei species.

Summary: The insulin signaling pathway is crucial in various physiological aspects, with insulin-like growth factor binding proteins (IGFBPs) playing a key role. This study identified and analyzed three IGFBP genes in the Pacific white shrimp genome, showing that LvIGFBP1 has multiple domains and higher expression levels compared to LvIGFBP2 and LvIGFBP3. RNA interference of LvIGFBP1 resulted in a significant decrease in shrimp body weight increment, indicating its importance in growth regulation.

Summary: Underutilized seafood by-products have potential as feed ingredients to reduce fish meal and oil use in aquaculture. This study found that Brown shrimp processing remains (BSPR) can be a nutritive and growth promoting feed ingredient for Pacific Whiteleg shrimp. Diets with 50% BSPR replacement of fishmeal showed the best weight gain, and higher BSPR inclusion levels improved molting synchronicity and feed conversion ratios. Shrimp haematology was unaffected by dietary treatment, indicating good health and nutritional status.

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: Considering the important role of Monocyte to macrophage differentiation factor 2 gene (Mmd2) in growth and development, we analyzed the gene structure, expression profiles, and RNA interference of LvMmd2 in L. vannamei. LvMmd2 gene sequence was found to be highly conserved in transmembrane regions and widely expressed in different tissues, with the highest expression level in the eye stalk. Knockdown of LvMmd2 significantly promoted body length and body weight gain, indicating its role as a growth suppressor. Transcriptome analysis revealed significant changes in growth, metabolism, and immune-related signal pathways. These results enhance our understanding of the conservative structure and function of LvMmd2 gene and have potential applications in genetics and breeding.

Summary: Adding 2 g kg(-1) of surface-modified clinoptilolite to the feed can enhance the growth parameters of fingerling gilthead sea bream in a recirculating aquaculture system. It also improves weight gain, specific growth rate, and feed conversion ratio. However, there were no significant differences in body indices, blood parameters, or whole-body protein and fat levels among the different dietary levels of zeolite supplementation.

Summary: This study examined the effects of synbiotic and biofloc meal on the growth performance, gastrointestinal microbiota diversification, body composition, gut bacterial counts, and tissue histomorphology of Nile tilapia reared under different salinity levels. The results showed that adding synbiotic and biofloc meal significantly improved the growth performance, body composition, gut bacterial count, and tissue histomorphology of Nile tilapia. Therefore, adding synbiotics and biofloc meal to Nile tilapia diets is an effective strategy that can mitigate the potential adverse effects of salinity on growth and improve gut microbiota, body composition, and tissue histomorphology.
