Abstract
A study was conducted to determine the feasibility of replacing sea water with salt water in the culture of Giant Freshwater Prawn larvae, Macrobrachium rosenbergii (de Man) by using "Freshwater System". The prawn larvae were culture in 3 treatments: 100% sea water (Control), 50% sea water and 50% artificial sea water (Treatment 1 ), and 100% aitificial sea water (Treatment 2). Each treatment had 3 replicates at the stocking density of 40 larvae-1. 5 larvae from each tank were examined daily to determine their stages. When about 90% of the larvae metamorphosed to post larvae (PL), the experiment was terminated. The average survival rate of larvae during the study period for control, 50% sea water and 50% artificial sea water and 100% artificial sea water were 1.34%, 0.98%, and 0.4% respectively. These results showed that the 50% salt water was able to sustain larvae until metamorphosis. There was a significant different (p≤S0,05) in survival rate between both of the tanks. The mean rearing period of Macrobrachium rosenbergii prawn larvae to metamorphosis for Control was 53.33 ± 0.33 days while Tl-50% and T2-100% took 55.0 ± 0.58 and 57.7 ± 1.45 days, respectively. The result from this culture suggested that the 50% artificial sea water can culture prawn larvae. Based on the body composition, the survival and growth may be improved if food supplement was included in diet.
