Ecology of the free living forms of bioluminescent bacterial population along with the distribution of total heterotrophs in various sub-water regions of the Seto Inland Sea were attempted. Surface water bolstered the growth of total heterotrophs whereas bottom water endures luminescent procaryotes. Amongst various locale of the sampling area, high population were encountered in the inner regions when collated with the open regions of the Seto Inland Sea. Of 1182 strains identified, 10 different groups of total heterotrophs (867) as well as 8 species of bioluminescent bacteria (315) were observed. Pseudomonas-Alteromonas group was prevalent among TVC and these were decreased from the distance of the coast. Vibrio harveyi was found to be distributed more in all the sampling stations where as 2 species of the genus Photobacterium were noticed less frequently during the present investigation. However, substantiated proportions of V. fischeri was also recorded with some unusual members. Statistical analyses showed that salinity indirectly governs the distribution of these bacterial population and the analyses of variance revealed that these were distributed homogenously and were found to be significant in some sub-water regions.
