Study on the intestinal bacteria of Labeo rohita (Ham.)
The quantitative and qualitative aspects of intestinal bacteria of rohu fish (Labeo rohita) showed that total viable count of bacteria ranged from 9.9 x 106 to 1.4 x 107 CFU/g of intestine in different age groups of fish. The bacterial load was highest in the month of July and lowest in January. The genera of the isolates from intestine included Coryneform, Micrococcus, Flavobacterium, Cytophaga, Achromobacter, Aeromonas Enterobacteriaceae and Vibrio. Coryneform was the dominant group throughout the study period followed by Micrococcus and Enterobacteriaceae. Marked variations in the bacterial load and generic composition of intestinal bacteria were evident during the study period in different age groups of rohu fish.
