Enhancing production of fish through duck droppings in village pond of Chhattisgarh
Saugata Sasmal, Ankit Thakur and Goutam Roy
Experiments were conducted at Gunderdehi village of Chhattisgarh to study the physico-chemical and biological parameters in fish-duck integrated farming system for two years. The ponds were stocked with 8000 fingerlings/ha of Indian Major Carps (IMC) to utilize the maximum energy in the tanks through polyculture. Their average size was 90±20 mm. This ponds containing the fingerlings of Indian major carps was then integrated with ducks (Anas platyrhinos
) to serve the purpose of obtaining the eggs and meat as also deliver the excreta into the tank during wild grazing. Under such cultural practice at village level no supplementary feed was given to the fish while the ducks were fed with fresh kitchen leftovers and agricultural by products as kanki (broken cereal grains), kodha (rice bran), etc which are easily available commodities in rural areas. The mean dry matter loading rate of duck excreta was 6.1 kg/ ha /day into the pond and as a result the physico-chemical parameters as dissolved oxygen, pH, alkalinity changed significantly in treated pond and plankton volume also improved considerably. These parameters in totality affect the overall fish production raising from 1.7 to 2.8 tonnes / ha/year. The average egg production was 122 ± 9 bird-1
. The results conclude that integration of fish with duck is more profitable than farming fish alone with no inputs under rural conditions of Chhattisgarh.
