Medium and small reservoirs integrated breeding technology

The technology can make full use of the water resources of small and medium-sized reservoirs, give full play to the overall benefits of reservoir projects, promote the transformation of reservoir fish from extensive to intensive, and enhance the economic strength of reservoir management units.
The technology generally includes the following types. The first is the reservoir group fishery technology. Similar reservoirs with similar geographical locations and similar natural, social and economic conditions are organized through economic means and fishery development is carried out in accordance with the viewpoint of systems engineering. The second is fertilizing fish farming technology. Apply organic and inorganic fertilizers to the reservoir, increase nutrient elements such as nitrogen, phosphorus, and potassium in water, improve fertility, promote the reproduction of plankton, provide adequate feed for filter-feeding fish, and promote the development of benthic animals. The proliferation of aquatic plants, etc., provides certain food for edible fish. The third is the reservoir net enclosure technology. For reservoirs with relatively stable water levels, choose reservoirs with water depths of 2 to 5 meters, flat bottoms, good light, and microfluidic waters. According to different breeding targets, use a mesh of certain specifications to form a floor with the required area. Or no closed net area for fish breeding or adult fish culture. The fourth is reservoir cage culture technology. In sheltered areas with sunny water and microfluidic water, do not feed bait or feed cages, and cultivate filter-feeding or eating fingerlings or adult fish. The non-feeding cages are mainly set up in the rich nutrition reservoir area for the cultivation of quail and carp species. Feeding cages are used for the breeding of grasshoppers, grasses, cockroaches, earthworms and other edible fish or adult fish. The fifth is the three-dimensional ecological fishery technology. Taking fish farming as the main body, we combine agriculture, fishery, agriculture, animal husbandry, or fish farming and animal husbandry into an organic whole to form a virtuous circular ecosystem. The specific forms include fish, food (grass, vegetable), fish and livestock, fish, Combination of poultry, fish, livestock, poultry combination, fish, food (grass, vegetables), livestock, poultry combination. Sixth, it is the intensive culture technology of reservoir dams and bays or small reservoirs. Choose a bay with small bay mouth, large abdomen, best bay bay, and a small area of ​​about 100 mu. The bay area will be built in the bay mouth to form a relatively stable water area, or the use area is less than 500 mu and the water source is relatively stable. A small reservoir, a rational transfer of pond intensive culture technology, implements a multi-species, multi-level, multi-age group of fish release models, combined with feeding, fertilization, and artificial intensive culture. Seventh, transplantation and domestication technology. According to the ecological conditions of the reservoir, fish that have high economic returns, such as silverfish and cockroaches, should be transplanted into the reservoir in a localized manner, and they should be allowed to form productive populations. The proliferation of river crabs and shrimps should be carried out in reservoirs with aquatic resources.
This technology is applicable to small and medium-sized reservoirs, lakes, and ponds throughout the country. When used, it should be based on the ecological, economic and other conditions of the reservoir, combined with market demand, choose one or two or more technologies in the above-mentioned integrated aquaculture technology.
