“…Similar bacteria may occur in the intestine; however, the techniques used in this study were not efficient to identify them in that region. Gut flora has been reported in lower organisms such as abalone (Erasmus et al, 1997), and in several higher vertebrates such as humans (Eckburg et al, 2005), cattle (Maki & Picard, 1965), mice (Rawls et al, 2006), frogs (Pryor, 2008), and other fish (Sugita et al, 1989;Bairagi et al, 2002;Voveriene et al, 2002;Ringo et al, 2003;Korneva, 2008). Observations by Bairagi et al, indicate gut micro bacteria as an important source of amylase, cellulose, lipase and protease, while Voveriene et al, has recorded their role in hydrocarbon degradation in the fish gut.…”

SUMMARY:The morphology of the gastrointestinal tract of adult Nile perch was described using standard SEM procedures. Investigations revealed the presence of cardiform teeth in the oral cavity, goblet cells and finger print-like microridges on the hard palate and oesophagus lumenal surface. Elaborate patterns and bacterial cells were observed on the stomach lumenal surface and intense foldings in the intestinal region. These observations provide a better understanding of the morphology of the gut in Nile perch and how it is suited for its digestive function.

“…Later they become predominant in the intestines of adult fish. Investigation results suggest that bacteria of the genera Aeromonas, Pseudomonas and Flavobacterium-Cytophaga prevail in the bacteriocenoses of the digestive tract of freshwater fish (Ringø and Birkbeck 1999; Vesta Skrodenyte-Arbaeiauskiene 2000; Voveriene et al 2002). The impact of feeding intensity and food on the qualitative and quantitative composition of intestinal bacteriocenoses of fish was studied by a number of scientists (Ringo and Olsen 1999;Pucci et al 2004;Vesta Skrodenyte-Arbaeiauskiene 2000;Voveriene et al 2002).…”

Microflora of the environment plays an important role in the formation of the microflora of the digestive tract of fishes (Strom and Olafsen Microbiology of poecilotherms Elsevier, Amsterdam, pp 181-185 1990; Hansen et al. Appl Environ Microbiol 58:461-470 1992). Compared to water, digestive tract is an ecosystem far richer in nutrients and therefore more favorable for the growth of the majority of bacteria. Definitely, not all bacteria in food which gain entry in the digestive tract of fishes establish themselves there (Yan-Bo Wang et al. Aquaculture 281(1-4): 1-4 2008).Part of them adapts themselves in the digestive tract, whereas the others are digested by the enzymes produced by the host organism. Microorganisms present in the digestive tract feed on the food of the host organism which is digested by the enzymes produced by them and by the latter. 'Chymous' gets formed which decides the abundance and qualitative composition of microorganisms present in digestive tract.

“…The initial colonization process is very complex at larval and fry and mostly depend on the ¢sh type, nutrients/food and surrounding conditions (Bignell 1984;Voveriene, Mickeniene & Syvokiene 2002). The total bacterial load at the larval stage is low (approximately 10 2 CFU larva À 1 ) before active feeding (Munro, Barbour & Birkbeck 1994;Verner-Je¡reys, Shields, Bricknell & Birkbeck 2003;Reid, Treasurer, Adam & Birkbeck 2009), and this initial load is mostly derived from the water by larvae to maintain osmotic balance (Tytler & Blaxter 1988;Reitan, Natvik & Vadstein 1998).…”

The gastrointestinal (GI) tract of an animal consists of a very complex and dynamic microbial ecosystem that is very important from a nutritional, physiological and pathological point of view. A wide range of microbes derived from the surrounding aquatic environment, soil/sediment and feed are found to colonize in the GI tract of fish. Among the microbial groups, bacteria (aerobic, facultative anaerobic and obligate aneraobic forms) are the principal colonizers in the GI tract of fish, and in some fish, yeasts are also reported. The common bacterial colonizers in the GI tract of freshwater and marine fish include Vibrio, Aeromonas, Flavobacterium, Plesiomonas, Pseudomonas, Enterobacteriaceae, Micrococcus, Acinetobacter, Clostridium, Fusarium and Bacteroides, which may vary from species to species as well as environmental conditions. Besides, several unknown bacteria belonging to Mycoplasma, Arthrobacter, Brochothrix, Jeotgailbacillus, Ochrobactrum, Psychrobacter and Sejongia species in the GI tract of different fish species have now been identified successfully using culture‐independent techniques. Gnotobiotic and conventional studies indicate the involvement of GI microbiota in fish nutrition, epithelial development, immunity as well as disease outbreak. This review also highlights the need for manipulating the gut microbiota with useful beneficial microbes through probiotic, prebiotic and synbiotic concepts for better fish health management.
