عنوان مقاله [English]
The increasing population and the limitation of agricultural land and food supply sources require that new programs be set up to increase production at unit level. Nowadays fish products can be multiplied in various ways, including the multi-species breeding of fish called poly culture, cage breeding, rehabilitation of water (circulating water), exploitation of hot water flows of power plants, etc. One of the methods of increasing the production of fish farming pools is fish farming and poultry, especially ducks and geese, which coexist peacefully. In the light of the above, the Integrated Fish-Duck and Goose project aims to provide methods and determine the benefits of fish farming in poultry-water-repellent such as increasing production per unit area, reducing costs, helping the natural reproduction of the pool through improved conditions. The physical and physical properties of water and soil were carried out in a single unit in the province of Guilan. In general, five months of fish breeding, three duck periods and a goose period were also raised. The total amount of the product in a harvester is 8800 kg, in other words, the production capacity of meat per one hectare in a fish farming pool reaches 9 tones, which is 2.6 times the normal harvesting of fish in fish breeding ponds.
