Abstract
Feed is a very important factor in vannamei shrimp culture. The initial stage of stocking is the cultivation stage requiring a higher percentage of feed. The application of probiotics in intensive shrimp culture is known to have a significant effect on the survival of vannamei shrimp. Encapsulation can increase the viability of probiotic bacteria compared to free cells without encapsulation. Research has been carried out on the provision of encapsulated probiotic consortia in vannamei shrimp culture. The purpose of this study was to observe the effect of the selected probiotic consortium on the performance of vannamei shrimp. The research method used is the experimental method and the data obtained were analyzed descriptively. The observed parameters in this study were specific growth rate, survival rate and feed conversion ratio. The results showed that the fifth consortium of Bacillus and Lactobacillus bacteria could increase the growth rate of weight and length of vannamei shrimp (0.62% and 9.81%), survival rate (85.42%) and feed conversion ratio (1.08).
