Summary: Vitellogenesis-inhibiting hormone (VIH) negatively regulates reproduction in shrimp, and transcriptional silencing of Liv-SGP-G was successfully achieved with dsRNA injections. Although the treatment did not promote ovarian maturation, it was the first report of co-transcriptional repression of Liv-SGP-G using dsRNAs for homologous genes. This study indicates that subadult shrimp can respond to transcriptional silencing techniques.

Summary: Despite its versatility, the involvement of RNA m6A methylation in shrimp's response to ammonia nitrogen toxicity is not well understood. This study characterized the dynamic RNA m6A methylation landscapes induced by toxic ammonia exposure in the Pacific whiteleg shrimp. The global m6A methylation level decreased significantly after ammonia exposure, and many m6A methyltransferases and binding proteins were repressed. The differentially methylated genes were enriched in pathways related to metabolism, immune defense, and apoptotic signaling.

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 conducted a comprehensive transcriptomic analysis of neuro-endocrine organs related to shrimp ovary development, revealing differential gene expression in different organs during ovary development and the existence of tissue- or stage-specific modules of co-expressed genes. The study identified a rich set of genes associated with various signaling pathways preferentially expressed in specific tissues, providing insights into the regulatory network orchestrating ovary development in shrimp.

Summary: This study evaluated the dietary requirement of niacin and its effects on the growth, feed utilization, immunity, and disease resistance of Pacific white shrimp. The results showed that increasing niacin levels in the diet improved the growth performance, feed utilization efficiency, and disease resistance of the shrimp. The optimum niacin requirement for Pacific white shrimp was estimated to be around 130 mg/kg diet.

Summary: This study examined the use of high-pressure assisted thermal processing (PATP) for shrimp maturation and cooking. PATP treatments at 100-350 MPa improved peelability and maintained similar quality properties compared to conventional methods, while higher pressure (600 MPa) resulted in overprocessing and decreased quality.

Summary: The study evaluated the addition of mussel meal as a feed additive for whiteleg shrimp to improve growth and cold resistance. The results showed that adding 3% or 4% mussel meal had similar effects as the control group, while adding 1% or 2% mussel meal significantly improved final weight, weight gain, and relative growth rate, and reduced feed conversion ratio. Furthermore, there were no differences in thermal shock resistance and survival among the treatment groups.

Summary: The study found that both corn starch and molasses addition can improve water quality, enhance biofloc growth, and affect shrimp growth and production in whiteleg shrimp culture system. However, adding corn starch resulted in higher shrimp growth rate and production compared to molasses addition.

Summary: The study used proteomic sequencing of hepatopancreas in Vibrio harveyi-infected whiteleg shrimp and found a significant number of DEPs, specifically showing changes in the expression levels of C-type lectins after infection. Different members of the CTL family exhibit varied responses to Vibrio harveyi infection, suggesting potential differential functions and providing theoretical guidance for further research on immune responses and pathogen infections in shrimps.

Summary: The study investigated the bacterial compositions of Foregut, Hindgut, and Midgut digestive fractions in shrimp gut, revealing different structural and functional roles. The results suggested that the gut microbiota in white shrimp is closely related to the analyzed fraction across the digestive tract, with specific metabolic functions carried out by bacteria communities in each gut fraction.

Summary: The indoor nursery systems for whiteleg shrimp production offer control and biosecurity, but the study found differences in water quality, growth performance, and production costs between the clean-water recirculating system, photo-heterotrophic system, and biofloc technology system. Density-dependent effects were observed in terms of growth performance at densities exceeding 1000 org/m3.
