Composite Fish Culture: Niches in One PondCatla (surface feeder)Rohu (middle feeder)Mrigal/Common carp (bottom feeder)

Different fish species occupy different feeding depths in the same pond without competing for food: Catla feeds near the surface, Rohu in the middle zone, and Mrigal or common carp at the bottom - letting a single pond support far more total fish than one species alone.
