Abstract/ Executive Summary:

Context: Determination of performance of ducks and fishes, and cost-benefit analysis in an integrated farming system of duck cum fish culture. Materials and Methods: An investigation was carried out in an integrated duck cum fish farming for a 6 months period from 1st January to 30th June, 2010 at Gaffor Goan Upazila in Mymensingh district. After preparing the ponds there Khaki Campbell breed of duck and four fish species fishes were stocked in the three ponds for finding out the performance of ducks offering prepared supplement feed with natural feed like aquatic weeds, insects, mollusks etc. in the ponds and fish production without given any food to fishes, but depended only on duck excreta, waste feed from ducks and naturally grown fish feed like Phytoplankton and Zooplankton. Finally all collecting data was tabulated, processed and recorded in computer Microsoft Excel sheet and finally it was analyzed by using Statistical Program for Social Science (SPSS, Version 22.0) computer program. Results: The egg production/year/female observed 245±14.21 was significantly (p<0.05) higher in Pond 3 than those produced 210±09.42 and 180±10.50 eggs/year/female in Pond 2 and Pond 1, respectively. Moreover, the matured body weight of duck obtained 2234±85.47g in Pond 3 was also heavier (p<0.05) than the duck in Pond 2 and Pond 1 had the matured weight of 1975±78.25 and 1850±87.44g, respectively. The average weight at six months period of various fishes in different ponds varied markedly amongst themselves. The average weight observed 550, 250, 200 and 120g in Pond 3 for Silver carp, Grass carp, Mrigal and Rajpunti, respectively was heavier than those fishes in Pond 1 having 480, 200, 100 and 80g for Silver carp, Grass carp, Mrigal and Rajpunti, respectively and in Pond 2 having 430, 150, 80 and 80g for Silver carp, Grass carp, Mrigal and Rajpunti, respectively. It was evidently established that the silver carp in each pond showed highest growth amongst to all other species of fishes. The net profit from duck cum fishes obtained 346200 Tk. was desirable and the maximum return of Tk. 135700 having from Pond 3, and then Tk. 108500 and 102000 from Pond 2 and Pond 1, respectively. Conclusion: It was concluded that an integrated duck cum fish farming was more desirable and profitable than the duck or fish farming alone.

Program Area: Farming System

Commodity: Duck, Fish, Farming System

Objectives:

To determine the function of duck excreta in recycling the nutrients & their effect on fish production as well as to develop an appropriate polyculture technique in integrated duck cum fish farming system suitable for the local ecological condition and to the prevailing of socioeconomic status of Bangladesh.

Methodology:

Study area and shape of ponds: The study area was at Gaffer Goan Upazilla in Mymensingh district. The average bottom area of the pond was 515m² and surface area of 66.67m x 12m (0.08 hactare). All the ponds were rectangular in shape and well exposed to sunlight. Preparation of ponds: One month prior to stock, the ponds were completely dried out by dewatering. The ponds were then kept exposed to sunlight for one month. In the interior time, the bottom was cleaned off of all unwanted weeds from the inner side of the pond embankments were also cleaned. Then the ponds were treated with lime (CaO) at the rate of 250 kg per hactare and then were sun dried for 7 days. After filling up the ponds with water from the deep tube well, urea & TSP was supplied initially at the rate of 40 and 60 kg per hectare, respectively. Selection of fish species: The following fast growing and widely cultivated carps were selected for stocking under polyculture system, such as Silver carp (Hypophthalmichthyn molitrix), Grass carp (Ctenopharyngodon idella val.), Mrigal (Cirrhinus mrigala Ham.) and Rajpunti (Puntius gonionotus). Stocking rate of fish: The stocking rate of fish in the ponds. The ponds were stocked with the fish species to utilize the optimum available food materials. Feed and fertilizer supplied to the fish: No extra feed and fertilizer was supplied to the fishes except the duck excreta & waste feed that fall directly into the pond. Soft green grass was supplied to the grass carps twice daily at the rate of 10-20% of their body weight. Construction of duck- shed Six duck-sheds were constructed over six ponds with locally available materials. Split bamboos were used to make the floor and wall. Top most centrally joined that were used to construct the roof. Larger size whole-bamboos were used to support the sheds over ponds. The sheds constructed for the first and second year. The floor area of duck-shed was about 13.5m2 (4.5m x 3.0m). The height of the shed was 2.8m. The pond bottom to floor height was 1.8m and from water level to floor was l.0 m. The floor of the shed was made of bamboo splits with a gap of about 1 cm between the two to allow the duck droppings and waste feed falling directly into the pond. The shed was constructed at the middle of the pond but to the one of the embankments. Stocking rate of duckling The stocking rate of duck in the ponds. Ducklings of Khaki Campbell breed were procured from the Central Duck Breeding Farm, Narayangonj. The number of ducks was raised in the fish pond depending on the quality of excreta which again was determined by the ducks species quality and quantity of feed given as well as the method of raising of ducks. Feed preparation and feeding of ducksFeed preparation and feeding of ducks The composition of duck feed was showed in Table 3. Duck feed was prepared with locally available agricultural products and byproducts such as broken wheat, broken maize, rice polish, till oil cake, fish meal, oyester powder, common salt and vitaminmineral pre-mix and chopped green soft grass was mixed with the feed at the rate of 2.5% of the total feed.

Achievement/Findings:

The present study was conducted to duck cum fish integrated farming to find out the performance of ducks and fishes. Three selected ponds were stocked with four species of fishes like Silver Carp, Grass Carp, Mrigal and Rajpunti. The 75, 100, 150 heads of Khaki Campbell breed were integrated with fishes for recycling the wastes of different selected ponds. The results revealed that duck excreta was good source of nutrients that was readily soluble in pond water and became available for growing of fish feeds as Phytoplankton and Zooplankton. Moreover, the duck excreta improved the nutrient level in the fish pond ecosystem at productive range. Duck also showed better growth rate and attained a reasonable matured body weight with a good egg production performance. The average number of yearly egg production per female observed 245±14.21 was significantly (p<0.05) higher in Pond 3 and then 210±09.42 and 180±10.50 in Pond 2 and Pond 1, respectively. The matured body weight of duck obtained 2234±85.47g was also significantly (p<0.05) higher in Pond 3 and then 1975±78.25 and 1850±87.44g in Pond 2 and Pond 1, respectively. The fish growth was highly satisfactory with duck droppings and waste feed of ducks received by the fishes in different ponds. The highest matured body weight and egg production performance of ducks in Pond 3 was probably due to have the nutrient availability and suitable environment per duck in Pond 3 than had other ponds. The net profit observed 253800 Tk. in the integrated system of duck cum fish farming was desirable. Thus, it was concluded that an integrated duck cum fish farming system was more desirable and profitable than the duck or fish farming alone.
