Summary: This study aimed to develop a cost-effective SNP panel for genetic characterization of Macrobrachium species in Cameroon. After screening a previous set of 1,814 SNPs, a total of 72 core SNPs were chosen using conventional approaches and their discriminatory power was tested using various analyses. The panel of prioritized SNPs successfully distinguished Macrobrachium species with 100% accuracy, demonstrating its potential usefulness for this economically important species in Cameroon.

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: This study investigated the effect of environmental differences on the growth traits of candidate parents in a breeding program for Macrobrachium rosenbergii. The heritability and genotype by environment interaction were estimated for harvest body weight (HBW) and average daily weight gain (ADG) in communal rearing stage (CRS) and individual rearing stage (IRS). The results showed that the heritability decreased in the IRS compared to the CRS, and the impact of IRS on the growth traits was more significant for males. It is suggested that IRS should be considered in parent selection and mating schemes for more accurate selection of parents in breeding programs for M. rosenbergii.

Summary: This study investigated the intestinal microbiota of freshwater prawns at different developmental stages using 16S rRNA sequencing. The results showed that richness and diversity of the microbiota increased with growth, and significant differences were observed in the relative abundance of gut microbiota between the different stages. The study provides valuable information on the differences in intestinal microbiota during different developmental stages of freshwater prawns.

Summary: The Yorkie gene and two Cactus isoforms were characterized in oriental river prawns, and their roles in the immune defense were investigated. The study found that MnYorkie negatively regulated the expression of immune-related genes and promoted the transcription of MnCactus, thereby influencing the immune system of the prawns.

Summary: Breeding programs for oriental river prawns would benefit from understanding the heritabilities and epistatic interactions of growth-related traits. This study found that the heritability estimates for these traits were moderate, ranging from 0.10 to 0.22 for females and from 0.08 to 0.26 for males. The additive x additive epistasis had a directional and synergistic effect on body weight, body length, and two processing traits. This knowledge can inform selection programs and lead to more accurate genetic evaluations and desirable gains in oriental river prawns.

Summary: An 8-week feeding trial was conducted to determine the dietary arginine requirement of oriental river prawns. The results showed that prawns fed with 2.02% dietary arginine had higher survival, growth performance, and feed utilization. Muscle samples analysis revealed increased crude protein content, lipid content, and muscle arginine content in prawns fed with 2.02% arginine. Moreover, antioxidant activity and immune-related gene expression were significantly improved in the same group. The broken-line regression analysis indicated that the optimal arginine requirement for oriental river prawns was 2.12% of dry matter (5.61% dietary protein).

Summary: Cyclin B3 (CycB3) is involved in the regulation of cell proliferation and mitosis, and it is predicted to play a crucial role in the reproduction of Macrobrachium nipponense. This study revealed that CycB3 is involved in the process of spermiogenesis, oogenesis, and embryogenesis in M. nipponense. Inhibiting CycB3 expression resulted in lower sperm abundance and disruption of testis reproduction in M. nipponense.

Summary: The study demonstrated that the synergistic effects of emodin and Clostridium butyricum significantly enhanced the antioxidant capacity, immune-related gene expression, and survival rate of Macrobrachium rosenbergii under ammonia stress. The optimal combination of these components was found to be 250 mg/kg (2x 107 CFUg(-1)) and 50 mg/kg.
