Abstract

This research aimed to determine the effect of different stocking densities of vanamei shrimp and the provision of Bacillus sp. in the cultivation media on the growth and survival of vanamei shrimp (Litopenaeus vannamei). This study used a completely randomized design with four treatments and three replications, namely treatment A: density of vanamei shrimp 22 individuals/liter; treatment B: density of white shrimp 27 individuals/liter; treatment C: density of white shrimp 32 individuals/ liter and treatment; and D: density of white shrimp is 37 individuals/liter. Bacillus sp. was added to each treatment at 1ppm. The parameters tested were absolute weight growth, absolute length growth, daily growth, and survival. Meanwhile, the water quality parameters measured are temperature, pH, salinity, dissolved oxygen, nitrite, and ammonia. The data were analyzed for variance using the SPSS application, and the water quality data were descriptively analyzed. Compared to other stocking densities, treatment A was the best based on results. This can be seen from the data of absolute growth, absolute length growth, daily growth, and survival. Water quality data viz. temperature, pH, salinity, dissolved oxygen, nitrite, and ammonia are still in the water quality range suitable for the life of the vanamei shrimp test animals.
