Summary: The inclusion of H. pluvialis in the feed of P. clarkii significantly improved growth performance and gut microbiota, while also exerting antioxidant effects. The recommended inclusion level of H. pluvialis powder was 0.6%.

Summary: The study found that dietary protein sources did not significantly impact the growth performance of Procambarus clarkii, but crayfish fed with animal protein exhibited significantly higher richness in taste, with higher levels of inosine-5'-monophosphate. The analysis of volatile components in the muscle tissue also showed significant differences between dietary animal protein and plant protein.

Summary: The aquaculture of red swamp crayfish has grown rapidly in recent years, but limited knowledge on the physiological responses to different feeding levels has hindered scientific feeding strategies. This study found that different feeding levels affected the growth performance and feed utilization of juvenile P. clarkii. Physiological variables were significantly correlated with feeding levels, with high feeding levels leading to oxidative stress in crayfish. High feeding levels (6% BW day(-1)) did not benefit P. clarkii.

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.

Summary: This study delved into the major component of animal egg yolk and its transcriptome in decapod crustaceans, revealing expression differences of different VTG genes in reproductive stages and tissues, providing valuable information for studying crustacean reproduction and delaying the spread of invasive species.

Summary: The study found that reducing dietary protein levels did not significantly affect the growth performance of Procambarus clarkii, but juveniles fed a diet containing 26% protein had higher crude protein and ash contents in their muscle. Additionally, the contribution of Hydrilla verticillata to the growth of P. clarkii increased when dietary protein levels decreased, suggesting that reducing protein levels in ponds could help decrease production costs.

Summary: Citizen scientists can play a unique role in surveilling and detecting biological invasions relevant to management. In this study, a classroom citizen science program discovered the first occurrence of the invasive red swamp crayfish Procambarus clarkii in northern Idaho, United States. Students from a secondary school in Lewiston, Idaho detected an unfamiliar crayfish species in storm water ponds, which they identified as P. clarkii. The identification was confirmed through crayfish morphology and mitochondrial DNA barcoding. Management agencies were promptly informed and have begun monitoring and removal efforts for this population, which is located near a major river in the region. P. clarkii's predilection for invading freshwater ecosystems in urban and suburban landscapes makes it well-suited for surveillance by classroom citizen science programs.

Summary: The red swamp crayfish, Procambarus clarkii, is an economically important species in China. Growth-related traits in P. clarkii are affected by both additive and non-additive genetic effects, with the period from the 4th molt to the 9th molt being particularly important for growth. The environment also plays a significant role in the expression of genes affecting these growth-related traits.

Summary: The reproductive biology of the red swamp crayfish in western Japan has not been well studied. Monthly samplings and laboratory observations were conducted in a pond in Okayama, revealing that male crayfish were in Form I and the females could start reproducing approximately five months after hatching.

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: 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.
