چکیده
workers (Aitken, 1901; Alcock, 1902; Fry, 1912; Hora, 1927; Graves, 1930; Prashad and Hora, 1936; Covell, 1927 and 1941) confirmed the utility of larvivorous fish in India. The Top Minnow extensively used in Italy, South America and West Indies, and imported into India about 1929 from Italy and Siam, has established its reputation as a valuable larvicide. Three imported and twentytwo indigenous varieties of fish have so far been described in detail. The three exotics are fairly well known, viz (1) the Top Minnow (Gambusia affinis), the most extensively used fish, and distributed free by the various fisheries and anti-malaria centres in India; (2) Gold fish (Carassius), the popular ornamental fish imported from the Far East; (3) Barbados Millions (Sebastas) used in Ceylon, but could not be acclimatized in India.
