Abstract

Probiotics treatment on black tiger shrimp (Penaues monodon) treatments was carried out in 7-liter square aquarium and 240 tails shrimp post larvae (PL) were used in this trial. The trial was done in duplicate. In this study, treatment A was representing an additional of probiotics Bio-Aqua and nitrifying bacteria, treatment B was representing an additional of probiotics Bio-Block and nitrifying bacteria treatment N representing an additional of nitrifying bacteria and treatment C as a control group without any additional of probiotics or nitrifying bacteria. A number of 30 tails of PL were randomly distributed into each of the four different treatment groups. Probiotics contain of Bacillus sp. was added to treatment A and B tanks. Survival rate and weight gain among three different treatment groups and control were determined at 18, 31 and 63 days after rearing. There was significance different (P<0.05) of survival rate and body weight gain of PL in probiotics supplementation groups. There was significance different (P<O.05) in water quality for ammonia, phosphate, nitrite and nitrate. Only nitrite test showed no significant difference (P>O.05) occurred between treatment groups A, B and N with control group. Overall, better water quality of ammonia, phosphate and nitrate was achieved in treatment A, B and N groups. After challenging PL with pathogen Vibrio sp., by immersion for 14 days, probiotics group B had 90 o/o of survival rate. In addition the PL in probiotics treatment appeared healthy and active compared to treatment N and control.
