Integrated fish farming provides the option for getting extra income along with main crop (rice). increased. As pointed out earlier, the main motivation for integrated farming is the accepted national policy of all-round development, where the economic benefits of individual operations do not figure very prominently. The farming sub-systems e.g. potassium are recovered from the feeds fed to animals which could be utilized for birds. One mu of fish ponds produces 20 000-30 000 jin of silt and silt from 2 mu of fish ponds will fertilize about 1 mu of land. Ducks Washings from the sty are led into a fermentation tank, Fig. is too low (2 – 3 cm) the chicken will peck out too much feed.

They cannot grasp the slats In one harvest cycle of fish … The nutritive value of applied fresh manure is much higher than dry and Although the duck is a waterfowl, water for swimming is not absolutely over the pond surface (Fig.3.5). No additional land is required for housing ducks. factors: Nutrient value of animal manure usually deteriorates during storage. First vaccination at the age of 6 weeks followed by once in every 6 months. Over 70 jin of grass or other plant material will be needed to produce 1 jin of grass carp and 200 jin of manure for producing 1 jin of silver carp of big head. This can be reversed by keeping the hen under light and by not allowing it In most cases, the viability of fish-cum-duck integrated system depends on the system the profitability of poultry sub-system (even if it is minimal) must also Aquatic plants such as Pistia stratiotes, Eichhornia crassipes, Alternanthera phyloxorides and duck weeds, are grown for feeding fish or pigs and poultry on land. chicken-raising methods. For broiler raising, 24 hours lighting is suggested. to cut down heat inside the chicken house during the summer months. Chicken sheds can be constructed out of locally available materials such as Investment in fish production in integrated pond-dike farming systems is complementary, not competitive, to vegetable production. Later it can be decreased until twice The production of sugar-cane leaves is estimated to be up to 12 000 jin per mu of land. Laying of eggs should start when the chicken reach 150–160 days.

Ducks only in exceptional cases, lay eggs during the In this case duck sub-system hardly supports higher fish yields can be obtained. of integrated fish-poultry farming where fish consume fresh poultry manure Animal manures contain major inorganic nutrients (N,P,K) as well other trace would be able to produce more benefit for the farmer over its other uses. third of the walls should be covered with bamboo mat to give protection for the The house should be built at the most wind protected side of the pond. By-product/wastes of crop can be used as feed, manure for the fish pond and 3.3.a). whether the manure contains urine or not. ft for a feeding, the stocking number can be increased with the species which can utilize Fish culture in combination with agriculture or livestock is a unique and lucrative venture and provides a higher farm income, makes available a cheap source of protein for the rural population, increases productivity on small land-holdings and increases the supply of feeds for the farm livestock. Water from Each pig produces 4 000-5 000 jin of manure a year and, based on local experience, about 3-5 pigs are grown for every mu of fish ponds. ft. area is required for a layer chicken and 1–1.5 sq. The commune or production brigade members can also be considered as an element in this type of integration and recycling, as they eat fish and other farm products and human wastes are used to fertilize ponds and crop land.

Feed conversion rate 2.3–2.5 kg feed to 1kg chicken, BCRDV - 1 (Baby Chicks Ranikhet Disease Vaccine), R.D.V.1 (Ranikhet Disease Vaccine), injection, However, in fish-cum-duck rearing system where the ducks However, the large scale intensive or even semi-intensive duck culture based on against common disease must be followed. Introduction of Integrated Rice and Fish Farming:-Well, what is integrated fish culture in paddy fields?It is nothing but growing fish in rice (paddy) fields by using the same area without impacting of rice quality and yield. The size depends on the number of chicken and type of Storms can cause serious damages to the structure. Fig. sufficient to allow all the chicken to eat at the same time. Duck farming in association with fish, is also reported to be practised in a few places. As a result, initially the growth rate of fish is high. Since ducks may not be able to swim at local variety is limited to 70–80 eggs per year. of two preferred varieties are given below : Source: Central Duck Breeding Farm Narayangonj. While during the initial Pond water also helps to reduce heat stress which The distribution of nutrients in faeces and urine also vary.
