| Abstract: | The aerobic bacterial flora in the intestine of farmed red seabream and black seabream was investigated at their larval and juvenile stages in relation to the microflora of ambient water and diets. The total bacterial number in the intestine was 7.4×104 and 3.4×104 colony-forming units (CFU)/fish for red seabream and black seabream, respectively. Among the intestinal flora, Vibrio (ca. 45%) and Pseudomonas (30%) were the most dominant bacteria.The total bacterial counts were 3.1×104 CFU/ml for rearing water, 2.1×107 CFU/g for live diets (rotifer and brine shrimp) and 1.2×104 CFU/g for artificial diets. Among the water bacteria, Pseudomonas (22%) and Moraxella (29%) constituted dominant groups, and in the live diets Pseudomonas (48%) was predominant. The incidence of Vibrio in waters and live diets was 7% and 11%, respectively. |
