Abstract
The efficiency of probiotics in supplementation with fresh feed namely clam meat and pellet feed (Irawan- 300-Grower) on the growth and survival of the green tiger shrimp Penaeus semisulcatus was studied in captivity. In each feed, one control (without probiotics) and one experiment (with probiotics containing Lactobacillus spp., Streptococcus spp., lipase and protease) were maintained. The experimental period was two intermoult duration (40 days). Water temperature, salinity, pH and dissolved oxygen were in the range of 27.5 to 31 °C; 25 to 30 psu; 7.8 to 8.2 and >4.5 ml/l respectively. Phosphate, nitrate, silicate and ammonia were estimated in the control and experimental shrimps. Phosphate and silicate concentrations were higher in experimental animals receiving pellet feed. The maximum weight gain of 5.20 g and length of 16.3 mm were found in experimental females fed with pellet feed. Low weight gain of 2.42 g and length of 3.7 mm were observed in control males fed with clam meat. Maximum (95%) survival was recorded in experimental females fed with pellet feed and minimum (60%) in control males fed with clam meat.
