Abstract:

The study implies on the efficacy of the Bacillus probiotic, Novib in controlling vibriosis on low saline Litopenaeus vannamei shrimp aquaculture pond at Muarmalla, East Godavari District, Andhra Pradesh, India. Novib was used since beginning in the test ponds. Control ponds were infected with Vibrio upon 42 days of culture. Physicochemical parameters of the ponds were also monitored. The laboratory report and visual observation of the animal confirmed the infection of the pond. Green and yellow colonies in the control ponds were enumerated to be 7.167±3.2 to 117.462±3.2 cfu/ml and 18.363±3.2 to 291.132±3.2 upon 49 days of culture respectively. Animals were observed to be with antenna cut, red discoloration of the body and minor necrosis in the tail. Feed intake was drastically dropped with mortality of 5-10 animals/day. Novib with the dosage of 500g/acre was then administered onto the pond water on a sunny day with aerators operated continuously on the first day. Novib of 10g/kg feed was given in two meals for a duration of 5 to 8 days and henceforth the pond was found to recover and gradually reduced mortality to zero in 5 days. Overall, administration of Novib on shrimp ponds has considerably improved the recovery of the shrimps with Vibrio infection and ensured healthy culture.
