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: In this study, the proteomics approach was used to characterize the hemocyanin expression profiles from Litopenaeus vannamei, revealing molecular diversity at the protein level. The research demonstrated that the glycan modification may contribute to the diversity and multiple immune activities of hemocyanin, which plays a crucial role in recognizing different pathogens.

Summary: This study investigated the effects of dietary cholesterol on various aspects of Pacific white shrimp. The results showed that a moderate level of cholesterol can improve the growth performance, antioxidant defense, immune response, osmoregulation, and salinity stress resistance of the shrimp.

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: Combining the carbon source and feed in one pellet in shrimp culture can improve shrimp performance, particularly when adding corn starch separately, leading to higher biomass gain and protein efficiency ratio. Carbohydrate addition resulted in a significant decrease in inorganic nitrogen and orthophosphate concentrations in water, while having no effect on biofloc and periphyton growth or the proximate composition of shrimp, biofloc, and periphyton.

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: This study investigated the molecular response of the pacific white shrimp to alkalinity stress using RNA-seq analysis. The results showed significant changes in ion regulation, digestion, and immune response, as well as inhibition of metabolic processes under alkaline stress. These findings provide important insights into the molecular mechanisms of pacific white shrimp under alkalinity stress.

Summary: The effects of silver nano/microparticles on juvenile L. vannamei shrimp were evaluated. The study found that short-term exposure to nanosilver did not affect the growth and welfare of the shrimp. However, it did induce changes in antioxidant capacity, chromaticity parameters, and hemocyte count in certain tissues. Overall, the use of silver nanoparticles as a prophylactic and therapeutic method for shrimp shows promise.

Summary: This study evaluates the effects of microplastic exposure through diet on Litopenaeus vannamei shrimp for seven days. Results show that microplastics were detected in the shrimp's gills, muscles, and hepatopancreas, and caused disruption in redox cells, lipid and DNA damage, as well as histopathological alterations such as edema and granuloma formation. These findings suggest that microplastic exposure can impact the health and welfare of L. vannamei shrimp and potentially affect the final consumers.

Summary: This study investigated the effects of nanoplastics on Litopenaeus vannamei. The results showed that nanoplastics exposure activated the lysosome pathway and affected the PI3K-Akt signaling pathway. In addition, nanoplastics disrupted hepatic lipid metabolism, caused oxidative stress, and damaged tissue structure in L. vannamei.

Summary: This study investigated the impact of Vibrio alginolyticus on the intestinal histomorphology and microbiome composition in Litopenaeus vannamei. The results showed that Vibrio alginolyticus infection caused exfoliation of intestinal mucosal epithelial cells and altered the tissue morphology of the intestine. It also affected the abundance and diversity of intestinal microbiome.

Summary: The acclimatization of certain ectothermic vertebrates to winter conditions involves reduced energy consumption, achieved through decreased movement activity, depression of cellular functions, or switching to anaerobic energy production. This study on crucian carp showed that winter-acclimatized fish exhibited lower metabolic rates and a shift to anaerobic energy production during anoxia. Winter dormancy in crucian carp is achieved through active reduction of energy consumption, a slowed metabolic rate, and a direct response to oxygen absence.

Summary: According to life-history theory, there might be different immunological strategies between reproductive and non-reproductive periods due to limited resources. Our study on two sympatric marine fish species, rockfish and sandperch, found that reproductive individuals showed lower immune function, but higher levels of natural antibodies in rockfish females, compared to their non-reproductive counterparts. On the other hand, reproductively active sandperch males showed lower levels of natural antibodies and higher neutrophil to lymphocyte ratio and spleen index compared to non-reproductive males. The study highlights the species-specific patterns of immunity and the potential influence of resource limitation and abiotic factors on immune trade-offs in fish.

Summary: This study focuses on cardiovascular development in altricial bird species, which has been less studied compared to precocial species. The researchers investigated the cholinergic and adrenergic receptor mediated control of arterial blood pressure and heart rate in the neotropic cormorant. The findings suggest that both cholinergic and adrenergic tone play a role in cardiovascular regulation in embryonic birds.

Summary: This study cloned the genes encoding glucokinase and glucose-6-phosphatase catalytic subunit in largemouth bass, revealing their distribution and transcriptional regulation. The results showed that the functions of G6pc and Gck in LMB were highly conserved in evolution, and the interconversion of glucose and G6P in the liver was well regulated at the transcript level under high starch diet, but a futile cycle was induced after a glucose load.
