Genome survey sequencing of red swamp crayfish Procambarus clarkii
Molecular Biology Reports, 2018Red swamp crayfish, Procambarus clarkii, presently is an important aquatic commercial species in China. The crayfish is a hot area of research focus, and its genetic improvement is quite urgent for the crayfish aquaculture in China. However, the knowledge of its genomic landscape is limited. In this study, a survey of P. clarkii genome was investigated

Copper Bioaccumulation and Depuration by Red Swamp Crayfish, Procambarus clarkii
Bulletin of Environmental Contamination and Toxicology, 1998Environmental 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.

The underwater acoustic activities of the red swamp crayfish Procambarus clarkii
The Journal of the Acoustical Society of America, 2012This study describes the underwater acoustic behavior of the red swamp crayfish Procambarus clarkii. The study was conducted both in a tank and in the natural environment. The tank was equipped with video and acoustic recording systems. Observations were conducted to identify the underwater acoustic signals produced and their association with ...

Journal of Forensic Sciences, 2019
AbstractAn 85‐year‐old man was found deceased floating in an irrigation ditch 18 days after his disappearance. During crime scene investigation, specimens of the red swamp crayfish Procambarus clarkii were found in proximity of the body. The feeding activity of these nonendemic crayfishes contributed to the formation of specific injuries on the body ...

Effect of abamectin on osmoregulation in red swamp crayfish (Procambarus clarkii)
Environmental Science and Pollution ResearchAs a widely used pesticide, abamectin could be a threat to nontarget organisms. In this study, the toxic mechanism of abamectin on osmoregulation in Procambarus clarkii was explored for the first time. The results of this study showed that with increasing abamectin concentration, the membrane structures of gill filaments were damaged, with changes in ...

Light preferences of red swamp crayfish (Procambarus clarkii)
Hydrobiologia, 2009Light 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).

Cathepsins are a group of lysosomal hydrolytic enzymes, broadly distributed in animals, and regulate various physiological processes. However, the immune functions of cathepsins are poorly understood in invertebrates. Therefore, to further provide information about the importance of cathepsins in the innate immune system of crustaceans, cathepsin A ...

Bioaccumulation of lead nitrate in red swamp crayfish (Procambarus clarkii)
Journal of Hazardous Materials, 1997Abstract Crayfish were exposed to intermediate concentrations of lead nitrate (150 μgl−1 and 1100 μgl−1) for periods up to 7 weeks. Lead clearance was monitored at 3 weeks following the 7 week exposure to the lower concentration. Lead bioaccumulation was demonstrated to be a time- and dose-dependent phenomenon in gills, hepatopancreas and abdominal ...

Hormones in the red swamp crayfish
1996Publisher Summary This chapter reviews the unique hormone structures in the red swamp crayfish. Several aspects of molting hormones and the possible biosynthetic significance involved in the molting process are described in the chapter. The chemical and molecular information for crustacean endocrinology is presented and the role of ecdysteroids as ...

Cadmium and lead uptake by red swamp crayfish (Procambarus clarkii) of Louisiana
Bulletin of Environmental Contamination and Toxicology, 1993Environmental contamination by heavy metals such as cadmium and lead is generally reflected by an increase in the tissue residues of aquatic animals. This is also true for fresh-water crayfish as reported by Bagatto and Khan (1987) for Orconectes virilis collected in the vicinity of Canadian smelters.
