Effect of probiotic Lactobacillus acidophilus on growth and survival of black tiger shrimp Penaeus Monodon (Fabricius) larvae

Abstract

The effect of probiotic Lactobacillus acidophilus was studied at the rate of 0.5 × 10⁹ to 1.5 × 10⁹   CFU/m³ water on growth and survival of black tiger shrimp Penaeus monodon larvae and post larvae (Nauplii to PL-20). Use of L. acidophilus at the rate of 1.5 × 10⁹CFU/m³ water showed significantly (P<0.05) higher length and weight over the control. At PL-20 stage, highest length (14.05 + 0.06 mm) and weight (3.27 ± 0.11 mg) was recorded in the treatment group 1.5×10⁹   CFU/m³ probiotic in rearing water that was 5 % and 27 % higher as compared to the control respectively. Survival at PL-20 stage was also significantly (P<0.05) higher over the control. Highest survival was found 58.25 ± 3.62 % with L. acidophilus at the rate of 1.5×10⁹ CFU/m³ that was 69.58 % higher as compared to the control (34.35 ± 1.33 %).
