Abstract

Pig dung was used as manure at 18 and 36 t/ha/year in carp polyculture (without supplementary feeding) for 270 days. It was observed that pig dung at both the levels did not degrade the physico-chemical properties (pH, dissolved oxygen and alkalinity) of water. The nutrient (phosphates and nitrates) level of water was higher in manured ponds than control ponds (no manuring, only supplementary feeding). Further, plankton levels (phyto- and zooplankton) were also significantly higher in manured ponds. The growth of Catla catla and Labeo rohita was significantly more in manured ponds than in control ponds. Growth of Cirrhinus cirrhosus and Cyprinus carpio was significantly more in ponds manured with pig dung at 18 t/ha/year than in control ponds and the growth of Ctenopharyngodon idellus was significantly more in control than in manured ponds.
