Larvivorous capacity of some indigenous fish of Haryana state.

Studies were undertaken to assess the role of some indigenous fish of Haryana state for the biological control of mosquitoes. Total of 28 fish species were encountered. Only six fresh water fish species Puntius ticto, Colisa fasciata, Aplocheilus panchax, Rasbora daniconius, Chanda nama, and Esomus danricus species possessed good feeding potential on mosquito larvae. The small size, well developed eyes and position of the mouth seem to be probably the important factors helping their voracity on mosquito larvae. These fish are either surface, subsurface or column feeders.
