Description
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 salt water in which animal osmotic resistance enables it to survive in hyperosmotic surrounding media for a period no longer than 48 hours.
