Última L'adaptation ecophysiologique et sanitaire de l'ecrevisse turque Astacus leptodactylus a des milieux saumatres: Contribution a l'astaciculture ArchiMer Barbe, D; Lautier, J; Vernet, G; Vey, A. This influence of salt media on different aspects of biological cycle and on most common pathogenic agents of Turkish freshwater crayfish Astacus leptodactylus is investigated survival and growing of juveniles O super(+) and intermediary individuals 1 super(+) are also studied. Total osmotic metabolism and reproduction, have been recorded. It appears that youngest individuals are particularly sensitive to low salinities (7 ppt.). Intermediary ones are more resistant nevertheless salinity does not improve neither survival nor growing. Copulation, laying and pleopod egg fixation are particularly affected by salt waters. The only promising application of salinity parameter on astaciculture could be whether prophylactic or curative treatment with concentrated...

In crayfish, the hemolymph glucose level shows an endogenous circadian rhythmicity which is expressed by a nocturnal glucose rise. This study shows that injections of serotonin and dopamine result in hyperglycemia and that injections of met-enkephalin decrease hemolymph glucose level as well as the nocturnal circadian glucose peak. Using immunocytochemistry, these neurotransmitters have been located in the eyestalk and their relationship with the CHH cell system is described.
