Chandrika, V (1996) Incidence of Antagonistic Bacillus spp. An eco-friendly aquatic priobiotic from aquaculture pond. In: The Fourth Indian Fisheries Forum, Proceedings, 24-28 November, 1996, Kochi .
Specific, non-pathogenic, pigmented bacterial species of Bacillus isolated from sedinientq of pokkali and perennial ponds of Narakkal are found to inhibit growth of pathogenic bacteria like Vihn'o~A, emn~onus.E . roli by competitive growth or by producing antagonistic antibiotics. Gramnegative slime-forming myxobacteriaceae. an undesirable organism in aquaculture ponds are also inhibited by two Bacillus spp. and can be included in demtus management system of bacteria showing antagonistic activity. Totally 7 species of Bacillus were isolated from sediments of aquaculture ponds during the period of study from March '95 to February '96 out of which pink pigmented Bacillus dominated and formed 12% of total heterotrophs. The results suggest that Bacillus spp.can be soccessft~lly used as probiolics in feed preparations and for management of detritus in intensive aquaculture operations to control the attack of microbial diseases reducing high shrimp mortality.
