FISH-CUM-DUCK FARMING

[/fusion_text][fusion_text]

The Integrated fish farming practices utilize the waste from different components of the system like- live-stock, poultry, duckery, piggery and agriculture by-products for fish production. 40-50 kg of organic wastes are converted into one kg of fish, while the pond silt is utilized as fertilizers for the fodder crops, which in turn is used to raise livestock.
The system of integrated farming is very wide.The system provides meal, milk, eggs, fruits, vegetables, fodder & grains in addition to fish. It utilizes the pond dykes which otherwise remain unutilized for the production of addition food and income to the farmer. There are various possible type of integrated farming one among them is given below:

 

Fish-cum-Duck farming

Fish cum Duck integration is most common in the developing countries. This type of integration is not popular in North-East states of India. Ducks are of several types and Khaki Campbell is recommended for fish-cum-duck integration. Fish pond being a semi-closed biological system with several aquatic animals and plants provides an excellent disease-free environment for the ducks. In turn, ducks consume juvenile frogs, tadpoles and dragonfly etc. there by making a safe environment for fish. Duck droppings go directly into the pond, which in turn provide essential nutrients such as carbon, nitrogen and phosphorous that stimulates the growth of natural food organisms. Ducks also help in aerating the pond water, along with bottom racking.
