Effects of domestication and temperature on the growth and survival of the giant freshwater prawn (Macrobrachium rosenbergii) postlarvae

Abstract

To understand the growth and survival during the postlarval stage of Macrobrachium rosenbergii, commonly known as the giant freshwater prawn, two experiments were performed which explored the differences in growth and survival rates between wild and captive postlarvae and the effect of temperature on survival and growth. The postlarvae reared at 27 and 30°C grew significantly throughout the experimental periods. The survival rates in the wild and captive postlarvae were similar at approximately 60%. The highest survival rate of 58% was found at 27°C.
