Growth and survival of transfection and non-transfection tiger shrimp (Penaeus monodon Fabricius) broodstock candidate in pond cultivation
Abstract Tiger shrimp (Penaeus monodon Fab.) is one of important commercial species in Indonesia. Low quality of shrimp fry due to the lack of good quality broodstock availability is shrimp cultivation problem that need to be solved. The study was aimed to evaluate growth and survival rate of broodstock candidate of transfection and non-transfection tiger shrimp. The study was conducted using four ponds with 2000 m2 in size in Takalar Regency. South Sulawesi. The treatment were A = transfection tiger shrimp broodstock candidate and B = non-transfection tiger shrimp broodstock candidate. Approximately 19.0-21.9 g/ind of shrimp were reared in 60 days in 0.25 individu/m2 (500 individu/2000 m2) stocking density. Commercial pelleted feed which content 38% of protein was fed three times a day in 5-3% of body weight dosage. Measured variables were growth performance, size distribution and survival rate. The result showed that shrimp growth were no significantly different (P>0.05), while survival rate and size distribution were significantly different (P<0.05). The dominant size of transfection shrimp was 41-50 g/ind. Whereas, non-transfection shrimp was dominated by 31-40 g/ind in size (48.39%). Survival rate of tiger shrimp broodstock candidate in this study ranged from 30.80 to 64.10%.
