The ponds were dewatered, freed from aquatic vegetation soil and the exposed to sunlight. Necessary arrangements were done to operate inlet and outlet systems. Quicklime (CaCO3) 250 kg ha-1 was added to the pond bottom. Then, the ponds were filled with ground water. After 5 days of liming, the ponds were fertilized with organic manure (cowdung @ 2470 kg ha-1). Quicklime (50 kg ha-1) was applied fortnightly to control water quality of different treatments.
