Fish harvesting in earthen ponds especially in large ponds is a significant task. Catch ponds are recommended to carry out efficient fish harvesting. For a 4-ha fish pond, a catch pond of the following dimensions will be sufficient; 2.5 m high, 10-m long, and 2-m wide. Catch pond should have a rocky bottom and sides. The bottom of catch pond is 80-cm below fish pond bottom. In order for this method to be effective in attracting pond fishes to enter the catch pond, water is introduced to fish pond through catch pond at a rate of 20-40 m3/hour. This particular catch pond serves 2-3 production ponds; 6-ha each.
