Same as Silver carp, this fish dominantly utilize the surface layer of the pond for food. Bighead carps have a faster growth rate than silver carp or the catla and it competes with catla for food (Rahman, 2005).
It is efficient filter feeder, but it filters larger organism, mostly zooplankton such as Rotifers, Copepodes and Cladocerans and larger algae such as Microcystis colonies (Ameen, 1987).
The maximum recorded total length 112 cm and weight 21.3 kg (Fishbase, 2009).
