Summary: Reoviruses have been isolated from various aquatic animals, with viral inclusion bodies found in redclaw crayfish. New primers were designed to detect reovirus in redclaw crayfish, with a newly developed RT-PCR diagnostic method showing high sensitivity and specificity for Cherax reovirus diagnosis. The method has a detection limit of 1000 reovirus genome equivalents and does not cross-react with other prawn pathogens.

Summary: An acute disease outbreak in Australian redclaw crayfish in a farm in Hubei, China, was caused by infection from Aeromonas hydrophila and Aeromonas veronii, possibly due to stress caused by temperature drops during crayfish transferring. Healthy crayfish had metabolic pathways such as antibiotic synthesis and enterobactin biosynthesis in their hemolymphs to maintain health, while the inhibition of these pathways led to microbiota structure disorder and disease occurrence. This study was the first to use high-throughput amplicon sequencing targeting the 16S rRNA gene for pathogen identification in aquatic animals.

Summary: In this study, 60 stable amplified polymorphic tetranucleotide microsatellite genetic markers were screened from the whole genome sequence of C. quadricarinatus, and a multiplex PCR system suitable for parentage assignment was constructed. The results showed that these microsatellite markers had high polymorphism and could meet the requirements for parentage assignment.

Summary: The rapidly spreading Australian red claw crayfish Cherax quadricarinatus in the Zambezi Basin is causing concern due to its potential impacts. This study quantified the socioeconomic impacts of C. quadricarinatus on the artisanal gillnetting fishery in Lake Kariba and found that it has led to significant damage and losses for fishers. The data from this study have important conservation and management implications, as crayfish pose a threat to food security and result in personal losses for fishers.

Summary: The genetic parameters of three growth traits in redclaw crayfish were assessed, and it was found that the number of families affected the heritability estimates. Male crayfish had higher body weight and body length averages than females, while females had a higher carapace length average. There were strong positive genetic correlations between these growth traits. The results indicate that larger numbers of families could contribute to more accurate estimation of heritability.

Summary: Redclaw crayfish, a freshwater decapod crustacean, is an important aquaculture species with a high mortality rate caused by Coxiella cheraxi, a rod-shaped intracellular bacterium closely related to Coxiella burnetii.

Summary: This study provides the first molecular evidence of natural, in ovo, vertical transmission of Chequa iflavirus and Athtab bunyavirus from farmed female redclaw crayfish in northern Queensland, Australia. Analysis of viral loads in eggs showed differences between viruses and farms, indicating varying effectiveness of surface sterilization methods. Evidence suggests that efficient egg surface sterilization can drastically reduce vertically transmission of fecal/oral viruses, while selection of resistant crayfish families or viral negative populations may be necessary for eliminating Chequa iflavirus and Athtab bunyavirus.

Summary: This study investigated the effect of pre-exposure of female redclaw crayfish to males on spawning and reproductive efficiency. The results showed that during the dissociated phase, the group exposed to males had a higher spawning rate but a lower molting rate. During the associated phase, there were no significant differences in spawning rate and molting rate between the exposed and control groups, but the exposed group had higher egg and juvenile production.

Summary: Redclaw crayfish (Cherax quadricarinatus) has experienced a breeding boom in China due to a breakthrough in seedling breeding technology. The study found that male individuals of C. quadricarinatus have higher meat yield rates and lower crude fat content compared to females. Furthermore, male individuals also have higher levels of flavor amino acids and polyunsaturated fatty acids.

Summary: This study revealed structural differences in the chela cuticle between male and female redclaw crayfish, and identified the high expression of genes related to chela structure in the red cuticle patch. Immunity-related genes were not specifically expressed in the red cuticle patch.

Summary: This study constructed small RNA libraries using redclaw crayfish hemocytes to investigate the differential expression and regulation mechanism of miRNAs after DIV1 virus infection. The results showed that 14 and 22 differentially expressed miRNAs were identified at 24 and 48 hours postinfection, respectively. Functional annotation analysis revealed that miRNA-mediated regulation was involved in relevant biological processes and signal pathways.

Summary: This study compared the protein content of two dominant hemocyte groups, GCs and SGCs, in crayfish Cherax quadricarinatus. Cell type-specific proteins were identified and their expression was further investigated. Molecular markers for GCs and SGCs were identified and their application in Eriocheir sinensis was analyzed. These molecular markers are useful tools for the research of crustacean hemocytes.

Summary: This study aimed to evaluate the effects of dietary phytic acid on the enzymatic activities of the hepatopancreas of the redclaw crayfish. The results showed that solubilized protein, reducing sugars, and soluble phosphorus showed significant responses to the interaction between phytic acid and phytase. The alkaline protease activity was negatively affected by phytic acid and improved by phytase inclusion.
