Light preferences of red swamp crayfish (Procambarus clarkii)

Hydrobiologia, 2009
Light intensity preferences of Procambarus clarkii (Girard, 1852) were evaluated in an indoor fiber glass trough, consisting of five equal length (4 m) zones with light intensities varying from dark to 1,000 lux (L), situated at the ‘Las Vegas del Guadiana’ fish farm in Extremadura (Spain).

Copper Bioaccumulation and Depuration by Red Swamp Crayfish, Procambarus clarkii

Bulletin of Environmental Contamination and Toxicology, 1998
Environmental contamination of copper occurs from two major sources: weathering and land-drainage. Mine production of Cu was estimated to be 307 million metric tons sometime ago (Nriagu et al 1979). A considerable amount of copper is contributed by the effluents of metal finishing industries to sewage sludge.

Antibacterial activity of hemocyanin from red swamp crayfish (Procambarus clarkii)

Fish & Shellfish Immunology, 2018
Hemocyanins (HMC): the copper-containing respiratory proteins present in invertebrate hemolymph, which plays many essential roles in the immune system. Currently, little is known about the HMC domains of Procambarus clarkii (P. clarkii) and their function in antimicrobial immune response.

Eleven polymorphic microsatellites isolated from red swamp crayfish, Procambarus clarkii

Molecular Ecology Resources, 2008
AbstractEleven microsatellites were isolated from a genomic DNA library enriched for CA‐ and GA‐repeats, and were characterized in 48 individuals of red swamp crayfish Procambarus clarkii. All 11 microsatellites were polymorphic with an average of allele number of 6.6 per locus.

Immunological, neurological, and intestinal changes in red swamp crayfish (Procambarus clarkii) exposed to the combined toxicity of Pyrogallol and microplastics.

Marine Pollution Bulletin
This study investigates the combined effects of pyrogallol (PG) and microplastics (MPs) on the freshwater crayfish Procambarus clarkii, evaluating their impacts both individually and in combination. Over 15 days, crayfish were exposed to 100 mg/L MPs, 10

Contrasting Patterns of Genetic Variability in Pet‐Traded Red Swamp Crayfish Procambarus clarkii and Its Feral Populations

Freshwater Biology
The ornamental pet trade has emerged as one of the most important pathways for the introduction of non‐native aquatic species. In the last two decades, freshwater crayfish have become a popular ornamental group, with numerous non‐native populations ...

Combined exposure to microplastics and copper elicited size-dependent uptake and toxicity responses in red swamp crayfish (Procambarus clarkia).

Journal of Hazardous Materials
In recent years, the toxicity of microplastics (MPs) in combination with heavy metals, particularly the influence of varying microplastic sizes on their toxic effects, has attracted widespread attention.

Research progress of pattern recognition receptors in red swamp crayfish (Procambarus clarkii)

Fish & Shellfish Immunology, 2023
Though Procambarus clarkii (red swamp crayfish) is a lower invertebrate, it has nonetheless developed a complex innate immune system. The crayfish farming industry has suffered considerable economic losses in recent years as a consequence of bacterial and viral diseases.

Effects of dietary oregano essential oil on digestive tissue structure and function, antioxidant and immune responses and gut microbiota of red swamp crayfish (Procambarus clarkii).

Comparative Biochemistry and Physiology Part B Comparative Biochemistry
Modifying the diet is an effective strategy to enhance the production and health of farmed red swamp crayfish (Procambarus clarkii). In this study the effects of adding dietary oregano essential oil (OEO) at 0, 100, 300, and 500 mg/kg concentrations were

Bioaccumulation of chromium in red swamp crayfish (Procambarus clarkii)

Journal of Hazardous Materials, 1997
Abstract Crayfish were exposed to a range of potassium dichromate concentrations (0.15, 0.30, 3.0 and 30 mg l−1) for periods up to 7 weeks. Chromium bioaccumulation in all tissues over the 7 week exposure period was not consistently time- and dose-dependent.
