The effect of acute and chronic cold exposure on heart rate (HR) and neuronal function in crayfish Procambarus clarkii and prawns Macrobrachium rosenbergii was addressed. This is particularly important since prawn farms of this species are used for aquaculture in varied climates world wide. The success of P. clarkii as an invasive species throughout the world may in part be due to their ability...
The Louisiana red swamp crayfish, Procambarus clarkii, which was introduced into east Africa in the 1950s or 1960s, has since widely dispersed. Previous work by our group has shown that P. clarkii can reduce populations of the molluscan intermediate hosts of human schistosomes through predatory and competitive interactions. Here, we investigate whether crayfish can reduce populations of Bulinus...
Three Kazal-type serine proteinase inhibitors, hcPcSPI2, hpPcSPI3, and hpPcSPI4, with complete cDNA sequences, were identified from a cDNA library of the red swamp crayfish, Procambarus clarkii. Semi-quantitative RT-PCR shows that hcPcSPI2 exists mainly in hemocytes while both hpPcSPI3 and hpPcSPI4 were detected in the hepatopancreas and the heart. Homology comparison and phylogenic analysis in...
A repetitive DNA element was obtained from a crayfish genomic library while attempting to isolate the gene for the pigment concentrating hormone (PCH) with an oligonucleotide probe. The probe was directed to the coding region of the octapeptidic hormone deduced from the amino acid sequence of PCH (1). The isolated clone contained a 14 nucleotide sequence tandemly repeated 30 times; eleven nucle...
