ABSTRACT

The beneficial and harmful microorganisms present in the gastrointestinal (GI) tract of fish. Microflora in the gastrointestinal tract of fish is vital role for healthy living of it. It is stated by many researchers that only few microorganisms spp. present in water are belongs to microflora in the gastrointestinal tract. Few of these spp. acclimatizes themselves in GI tract, whereas the remaining microorganisms are processed by digestive enzymes secreted by fish. The molecular approach provides a more complete picture about bacterial community composition than do cultured based methods. Application of Molecular identification based on 16srDNA gene by using Polymerase Chain Reaction (PCR). 16S r DNA approach has been successfully applied to determine the bacterial diversity present in GI of fish. In the present research work, the study of molecular characterization of microflora helps in some or another way for understanding the risk associated with pathogenic and non-pathogenic organisms and it will also help to study the common contaminants of water isolated from the intestine of Clarius batrachus for further research in aquaculture pathology. Keywords: Fish, 16srDNA, PCR
