Summary: This study evaluated the effects of carrageenan oligosaccharides (CRGO) on crayfish quality deterioration and protein hydrolysis during superchilling. The results showed that CRGO treatment significantly delayed quality deterioration and suppressed protein structural changes. Overall, CRGO has the potential to maintain better quality and stable protein structure during the superchilling process.

Summary: This study investigated the effects of dietary natural astaxanthin derived from Haematococcus pluvialis on the growth performance, pigmentation, digestion, antioxidant capacity, immunity, and response to air exposure stress of juvenile red swamp crayfish. The results showed that dietary astaxanthin significantly improved the survival rate and weight gain rate of juvenile crayfish. It also enhanced pigmentation and increased carotenoid content in the carapace, muscle, and ovaries. Astaxanthin supplementation increased the activity of digestive enzymes and antioxidant enzymes, and reduced oxidative stress markers in the crayfish. The optimal dietary natural astaxanthin content for juvenile red swamp crayfish was found to be between 63.55 to 84.40 mg kg-1.

Summary: This research evaluated and compared the capture efficiency of crayfish using traps with different numbers of entrances. The results showed that the number of entrances did not significantly affect the catch per unit effort (CPUE), but did significantly affect the CPUE by weight. Six-entrance traps were more efficient than five-entrance traps, and the number of entrances did not significantly affect the size of the captured crayfish.

Summary: Sexual size dimorphism is common in aquatic animals. A study on red swamp crayfish revealed that females have stronger disease resistance compared to males, as shown through differences in mortality rates, intestinal damage, apoptosis rates, melanism concentration, and reactive oxygen species in hemocytes. Female crayfish also exhibit more favorable immune gene expression patterns for disease resistance, suggesting that mono-sex breeding (all female crayfish) could be an important strategy for crayfish breeding.

Summary: This study investigated the accumulation of estrogenic hormones and UV-filters in red swamp crayfish, finding that UV-filters had higher concentrations than estrogenic hormones in crayfish tail tissue after exposure to environmentally relevant concentrations. The EDC concentrations in the crayfish tail tissue remained relatively stable throughout the exposure period.

Summary: The effects of ozone water and ultrasound cleaning on the microbial community diversity of crayfish were studied through microbial viable count and 16S rRNA gene sequencing. The results showed that the combined treatment significantly reduced the viable count of various microorganisms. Sensory evaluation indicated that the crayfish treated with ozone water and ultrasound cleaning provided a satisfactory sensory experience.

Summary: This study investigated the effects of Cu and PS compounds on the accumulation of microplastic particles and immune toxicity in Procambarus clarkii. Results showed that PS particles delayed Cu entry into the organism for a short time, but with longer exposure time, the toxic effects increased and could pose a food safety problem.

Summary: This study investigates the shell-loosening properties of crayfish and the changes in crayfish quality, microstructure, and protein fluorescent features after high hydrostatic pressure (HHP) treatment. New methods were established to measure the peeling performance of crayfish, and it was found that 200 MPa HHP treatment showed the best results in terms of crayfish peeling and quality. This research suggests that high pressure is a promising method for loosening crayfish shells and has potential application in industrial processing.

Summary: Purslane weed as a feed for crayfish can significantly increase the n-3 PUFA and carotenoid content, benefiting crayfish nutrition without affecting growth performance. It shows promise as an ingredient in crayfish diets with added value in carotenoids and polyunsaturated fatty acids. Further research is encouraged to determine the optimal inclusion of purslane weed in sustainable crayfish diets.
