Periphyton is being used traditionally as rich aquatic feed for fishes throughout the countries like Cambodia, West Africa, Srilanka, India and Bangladesh. In waterlogged rice environment, it can be judiciously utilized as feed source introducing periphytophagous fish. Studies supported rice straw as suitable substrate for periphyton growth. The study of gut content of Common carp (Cyprinus carpio L.) from a periphyton-based rice-fish culture system in Apatani Plateau of Arunachal Pradesh, India showed maximum of 60 genera of microflora and fauna with periphytic in nature. The farmers from this rice-fish culture practice are gaining an average fish production of 500kg ha-1 180 day-1 without employing any supplementary feed. Better selection and determination of appropriate stocking density of periphytophagous fish in waterlogged rice-fields might extend the rice-fish culture towards a sustainable and self-substrating periphyton based aquaculture (SSPBA) practice. Keywords: Periphyton; Sustainable agriculture; Rice-fish; Self-substrating; Common carp; Apatani plateau. © 2009 JSR Publications.

The presence of Bacillus species Were investigated in the intestine of 50 fish specimens common carp Cyprinus carpio weigh range between 1400-1500g in weigh were obtained from commercial farms in north of Baghdad through period of September to December 2010.The result revealed presence of gram positive, rod shape bacteria grow in the mesosphilic temperature range. The optimal temperature was 25-35C° facultative aerobes and produce catalase an enzyme. The bacterial antagonist activity was tested with fish culture pathogenic bacteria. The modified antagonistic method results showed that Bacillus subtilus could inhibit Aeromonas hydrophila after 24 hours. The highest level of antibacterial substances of this bacillus was produced in 48 hours. The aim of this study is to isolate and identify the Bacillus spp. and study its efficacy as probiotic against A. hydrophila in a fish culture.
