Resumo: | Since 1993, the New Caledonian shrimp industry has been faced with cold season mortality outbreaks of multifactorial origin. This pathology called “Syndrome 93” affects as well animals in grow-out ponds as broodstock after their transfer in maturation room, with up to 35% of mortality in 48 hours. From literature data and physiological studies on Litopenaeus stylirostris, several combinations of three abiotic parameters (temperature, salinity and feeding) have been tested during the breeders stocking period. This research allowed us to lower stress factors impact and to propose a transfer protocol which leads to an optimal physiological comfort of the animal. Results showed that survival rate is improved and spawning rates are twice higher. These findings have come up with a routine protocol of carrying out any transfer in a tank with water at temperature of 26°C, salinity of 26 ppt and no food supply during 48 hours. The use of this protocol in a commercial hatchery led to a significant broodstock survival improvement.
