ABSTRACT

The efficacy of aquarium fish Trichogaster trichopterus as a larvivorous fish was tried out in the laboratory and its predatory rate was found to be 1269 larvae per 24-hour exposure in glass bowl with 1.5 litre of water. Based on this finding a small scale field trial was carried out domestic containers including metal drums, glazwd earthern jars, and concrete tanks with Aedes aegypti breeding in Ngadatkyi North Qr., Bahan. The results show that this fish is an efficient biological larval control agent in domestic water containers.
