Abstract
An attempt has been made to assess the impact of poultry bird's integration on water quality of the fish ponds of different farmers of the Champawat district of Uttarakhand state. Experiment was conducted for two integration level of poultry birds (10 and 20 chicks/100m2) having fish stocking densities 3.0 fish/m3 in triple replication. Chemical properties of pond soil directly influenced the water quality of the pond. A decreasing trend in soil pH and increasing trend in organic carbon, nitrogen and phosphorus was found in integrated ponds. All parameters of physico-chemical properties of water in integrated ponds were found in permissible limits indicates the feasibility of higher stocking of fish and higher level of poultry bird's integration in cold water conditions without any adverse effect on water quality. This might be due to the cool, clean and well oxygenated water of the hilly region.
