Summary: This study analyzed a large dataset from a pedigreed giant freshwater prawn population over nine years to evaluate genetic progress for body weight and examined genetic changes in body dimensions and fitness related traits. The heritabilities for body weight and body dimensions were moderate, while estimates for early maturity and small blue claw male were low. Positive genetic correlations were observed among body traits, but negative genetic correlations were found with early maturity and small blue claw male. Genetic gain for body weight over eight generations was significant, but selection for high growth did not negatively impact other traits. The selection line showed substantial improvement in body weight compared to the founder stock from Mekong river.

Summary: This study investigated the relationship between intestinal microbiota and different male morphotypes of the giant freshwater prawn. The findings showed significant differences in bacterial abundance and gene expression among the three male morphotypes, as well as signal transduction pathways related to environmental information processing. The study also identified potential genes associated with different bacterial populations, providing a more effective method to manipulate male morphotype frequencies in prawn populations.

Summary: In this study, the complete and functional sex reversal was achieved by knocking down the MroDmrt11E gene in male prawns, resulting in the production of an all-male monosex population. Comparative transcriptomic analysis provided new insights into the genes involved in sexual differentiation affected by MroDmrt11E knockdown. The study also investigated the potential roles of MroDmrt11E in male sexual differentiation and analyzed the molecular regulatory relationships of candidate genes related to sexual differentiation.

Summary: White tail disease is caused by Macrobrachium rosenbergii nodavirus (MrNV) and an extra-small virus (XSV). This study detected MrNV in both adult and post-larval prawns, while XSV was not detected. Although no gross signs of the disease were observed, histopathological changes were found in the muscle of adult and post-larval prawns.

Summary: A variant of the Macrobrachium rosenbergii golda virus (MrGV) was found in Chinese prawns and compared with a variant reported in Bangladesh. Although there is currently no evidence that this variant causes disease, it is important to be vigilant as it may lead to mass death of prawn larvae.

Summary: A novel ssDNA virus, Macrobrachium hepatopancreatic bidnavirus (MHBV), was identified in giant freshwater prawn using metagenomic analysis and de novo assembly. This virus showed circular, eosinophilic inclusions in the nuclei of hepatopancreatic cells. The MHBV genome closely matched the polymerase B gene in the V1 fragment of Bombyx mori bidensovirus 2 (BmBDV2) and belongs to the family Bidnaviridae.

Summary: The aquaculture industry has faced financial losses due to disease outbreaks, particularly in the Macrobrachium rosenbergii aquaculture industry. Understanding the host's defense mechanism is crucial for providing effective defense measures. This study used RNA-seq technology to investigate the immune pathways and genes related to innate immunity in hemocytes from M. rosenbergii. The results identified differentially expressed genes and revealed their involvement in antibacterial activities against gram-positive bacteria. These findings contribute valuable data for disease prevention and provide a basis for improved prevention strategies.

Summary: This study aimed to determine the median lethal concentration (LC50) of combined total ammonia and nitrite for two species of prawns, and to determine their safety levels. The study found that the Amazonian freshwater prawn was more sensitive to the combined effect of total ammonia and nitrite, while the Rosenbergii freshwater prawn was more resistant.

Summary: This study evaluated larval production and water quality in a commercial hatchery using a closed recirculation system with artificial seawater. The results showed that there was no significant difference in larval survival and larval stage index between the two water treatments, but the depletion of magnesium and potassium ions in reused water may affect the survival of larvae.

Summary: This study investigated the potential of genomic selection to improve resistance to skin fluke and deformity in yellowtail kingfish. The heritabilities were low and the accuracy of genomic prediction was also low for both traits. Multi-trait analyses outperformed single trait models, highlighting the slow genetic progress due to low prediction accuracies in this study.

Summary: RNA-Seq was used to analyze gene expression differences in the liver and pituitary gland of male Nile tilapia with high and low growth performance, reared in saline or freshwater environments. The study identified genes related to growth regulation and reproduction, as well as hormone genes overexpressed in low-EBV tilapia. The findings provide valuable insights for improving growth performance in saline-adapted Nile tilapia.

Summary: The giant freshwater prawn is a popular tropical species widely cultured across the world with high market demand and attractive prices. Several countries have started selective breeding programmes for this species focused on growth rate, which has resulted in increased edible meat without negative effects on flesh quality attributes. Despite challenges, ongoing research aims to improve productivity in this species.

Summary: The study evaluated the predictive performance of new AI methods for disease resistance in striped catfish and compared them with traditional methods, showing that machine learning outperformed PBLUP, GBLUP, and ssGBLUP but was comparable to BayesR. Imputation of missing genotypes increased prediction accuracies, while multivariate models showed slightly decreased accuracies compared to univariate analyses.

Summary: Aquaculture plays a significant role in global food security, and its future development relies on sustainable aquafeed production. Fish meal is unsustainable and not eco-friendly, but it is still widely used in aquafeed production. Brewer's spent yeast (BSY) is a potential alternative protein source in aquafeeds, as it has high protein content, is cheaper than fish meal, and possesses beneficial properties. This review focuses on the utility of BSY biomass in aquafeed production.

Summary: The study isolated and characterized a lectin from the hepatopancreas of Macrobrachium rosenbergii. The lectin, known as lipopolysaccharide and beta-1,3-glucan binding protein (LGBP), showed hemagglutination like a lectin and exhibited antibacterial activity against certain bacteria. A sandwich ELISA system was developed to quantify LGBP in hepatopancreas and serum samples. The study revealed an increase in LGBP protein concentration in response to bacterial infection, suggesting its role in immunity.

Summary: A study was conducted to evaluate the on-farm performance of the genetically improved variety of Macrobrachium rosenbergii, known as CIFA-GI scampi, in Odisha State, India. The results showed that CIFA-GI scampi farmers achieved higher harvest size, growth rate, yield, sale price, and gross profit compared to non-GI scampi farmers. The study highlighted the superiority of CIFA-GI scampi and suggested that its adoption could lead to higher economic benefits for farmers.
