Description:
Field surveys of Penaeus duorarum have frequently observed co-occurrence of rising water temperatures, reproductive maturation and appearance of larval stages of the shrimp. This study investigated the use of water temperature changes, instead of eye enucleation, to induce maturation and spawning of pink shrimp fed only a compounded diet. The shrimp responded rapidly to changes in water temperature, spawning repeatedly within 7 to 14 days after water temperature was decreased to 20 ? 1?C and then increased to 28?C in the
1.2-meter-diameter, recirculating system. Survival to protozoea ranged from 83 to 97% and to post-larvae averaged 83 ? 3.2% when fed the diatom Chaetoceros gracilis. During the first 2 months, post-larvae grew from 0.072 mg to 109 mg.
