Abstract

Adult freshwater crayfish, Cherax quadricarinatus, were held for 21 days at five different salinities to assess their tolerance to saline conditions and to gauge the effect on sensory characteristics (taste). Significant mortality occurred at salinities of 18 and 24 parts per thousand (ppt) during the last 7 days of the treatment period. There were no mortalities nor adverse indications at salinities of 0 (control), 6 and 12 ppt. Results suggest a developed capability to tolerate saline conditions. The physiological mechanisms responsible for salinity tolerance and flavour enhancement are discussed.
