Bacterial species were isolated from the dead larvae and hatchery water of Backyard Freshwater Prawn (Macrobrachium resenbergii) hatchery at Noakhali, Bangladesh. The selected isolates were identified as Aeromonas sp., Bacillus badius, B. brevis, B. cereus, B. megaterium, Legionella sp., Micrococcus luteus, Moraxella Phenylpyruvica, Pseudomonas aeruginosa, Staphylococcus gallinarum and Streptococcus sobrinus. Formalin and antibiotics were used for invitro control of these bacteria. Three hundred ppm formalin effectively controlled the growth of all the selected species. Susceptibility test against the antibiotics showed that Gentamycin, Kanamycin, Streptomycin and Tetracycline should be the drug of choice to control bacterial flora of the hatchery.
