The Karachi division comprising 5 districts previously and now 18 Towns have been reported Dengue positive in 2010 after survey reports. The efforts to control DV-Vector Mosquitoes by present authors started in 2009. Now in the present paper the biological control by fishes in underground water tanks, overhead water tanks and open water tanks on ground has been reported. The result shows that the biological control by fishes in pure and fresh drinking water decreases the vector population. In biological control various type of locally found fishes were used, including Poecelia reticulata, Cyprinus carpio, Tilapia mosambicus and Opheocephalus sp. was used in this field experiment. All these four species gave satisfactory control of DV-Vector mosquitoes and Malaria plasmodium vector mosquito, the Anopheles sp. in water tanks.
