A total of 100 bacteria were isolated from crustaceans (shrimp, crabs, lobster), fish and water samples 9surface and deep sea) collected from Baluchistan coast. Identification of these isolates was performed by gram reaction, colonial and cellular morphology, pigment production and biochemical characters. Different characters such as resistance to antibiotic and heavy metals, pigment production, sugar fermentation, antibacterial and solubilizing activity were studied. It was found that 29% of the isolates showed production of different colour pigments which were affected by different concentration of heavy metals, 45% of the isolates showed multiple metal and antibiotic resistance, 40% showed solubilizing activity and 15% showed production of antibacterial substance, 16% strains were found to be lactose fementer where as 57% were non lactose fermenter.
