Microbiological studies in lobster culture rearing system at Kovalam laboratory, Chennai was carried out for a period of 150 days. The infected tissues, gills, gut and the exoskeleton of the diseased animal were subjected to various microbial analysis to study the distribution profile of luminous bacterial. The total heterotrophic bacteria in the water, sediment and animal samples were also determined. The total heterotrophic bacterial counts ranged from 1.6 x 10 to 26.3 x 10 cfu/ml in water, 2.4 x 10-24.2 x 10 cfu/ml in sediment and 3.4 x 10 to 4.2 x 10 cfu/ml in infected animals. The Vibrio harveyi population density varied between 0.8 x 10 to 9.6 x 103 LCFU/ml in water, 1.8 x 10 to 12.5 x 10 LCFU/ml in sediment and 1.3 x 10 to 2.2 x 10 LCFU/ml in animal. The high amount of luminescent bacteria accounted to the outbreak of tail fan necrosis in Panulirus homarus when grown in artificial rearing system.
