Abstract
The purpose of this study was to improve the quality of giant freshwater prawns postlarvae with the addition of sodium during the acclimatization medium from 12 ppt until 0 ppt. This research used Completely Randomized Design with 5 treatments and 3 replicates. The treatments of addition sodium were 0 (A); 25 (B); 50 (C); 75 (D) and 100 ppm (E) by using swamp water diluent. Experiment parameters included survival rate, oxygen consumption rate, level of osmotic work and water quality. The results indicated that the survival rates of giant freshwater prawns postlarvae were not significantly different among the treatments (varied from 84-91.7%). The osmotic levels were significantly different, with treatment on D can produce level of osmotic work on postlarvae more lower with a value of 185.68 mOsm/l H2O. Oxygen consumption rates also the best on treatment D that showed 1.378 mg O2.g-1.h-1. These results showed that the addition or without addition of sodium did not significantly affect the survival rate of giant freshwater prawns postlarvae, whereas osmoregulation (level of osmotic work) and metabolism mechanism (oxygen consumption) can add as much as 75 ppm sodium in swamp water. Water quality during acclimatization was still in range appropriate range to survival rate of giant freshwater prawns postlarvae
