The present study was undertaken to find out the incidence of Motile Aeromonas Septicaemia (MAS) in the freshwater aquaculture system in three districts viz. Nagaon, Morigaon and Sonitpur of Assam. A total of 293 number pools were screened for bacteriological and mycotic studies. Out of 293 pools screened, 91 (31.05%) were found to be positive for Aeromonas species, 131 (44.70%) for A. invadans and 55 (18.77%) for S. parasitica. Among Aeromonas genera, A. hydrophila, A. veronii and A. sobria were detected with 51.64%, 21.97% and 18.68% respectively. The prevalence of other Aeromonas species (7.69%) was also recorded during the study. Data on the seasonal prevalence of MAS reveal that the highest prevalence (62.63%) was recorded during the winter season followed by post monsoon (20.87%) and premonsoon (12.08%). Thus, study suggests that motile aeromonads remain an important bacterial pathogen from aquaculture point of view in Assam, which requires regular and constant examination of cultured fish to resist unexpected losses.
