Abstract

Bacterial disease control in shrimp ponds is currently taking a more environmentally friendly approach. This study aims to find out the effectiveness of Porphyridium aerugineum as a controller of Vibriosis in ponds. This research was carried out at with two treatments with three replications each. The first treatment is the administration of whole-cell microalgae P. aerugineum and the second treatment is Control without microalgae administration. Tigers shrimp was stocked at the stadia PL 12 (density of 8 shrimp fry/m2). The study used 6 ponds measuring 10m x 25m with a water depth of 80cm. Microalgae is given once a week. A sampling of pond water and sediment is carried out once in two weeks. The results showed that the addition of wholecell microalgae P.aerugineum in ponds can reduce the ratio of Total Vibrio bacteria and Total plate count in ponds water but not in pond sediments. In ponds fed microalgae P.aerugineum, shrimp survival rate and production were higher than those of in controls. The results of this study showed that the administration of microalgae as an additional supplement in ponds gave better results compared to the control.
