Abstract : This study examined
the effect of two Lactobacillus bacteria on protease activity and growth rate
of Litopenaeus vannamei. An experiment was conducted to examine protease
activity and growth rate. The experiment consisted of two treatment tanks, the
first tank was provided with artemia immersed in 2.6 x 1016 cfu / mL of bacteria
solution, the second tank served as the control tank. After 20 days, the L.
vannamei in the tank that received Lactobacillus have different answer
in growth, survival rate and protease activity (P <0.05) compared to the control, but no significant difference between Lactobacillus casei and Lactobacillus plantarum treatments. Within the digestive organ, protease activity of hepatopancreas and stomach demonstrated significant higher activity (P <0.05) compared to the intestine.
