Abstract
The present invention provides a method for culturing fish with net cage. Firstly the whole framework of net cage layout is set according to the condition of inland river water and reservoir area water. A frame is installed on the framework. Then a large net cage is installed on the framework. Filter economic fish are cultivated in the large net cage. Finally intensive culture net cages are installed in the large net cage. Bait throwing type fishes are cultivated in the intensive culture net cages. The method for culturing fish with net cage according to the invention adopts the tridimensional inter-culturing mode of different water layers with the fishes with different food habits according to the ecological principle. The bait throwing type fishes are cultivated at the upper layer of the filter economic fish which can eat the excrement and residual bait of bait throwing type fishes. The effects of pollutant discharge amount reduction and environment protection at the state that the cultivation effect of prior fish is guaranteed. The method of the invention also has the advantages of easiness, easy learning, strong adaptability and easy generalization.
Description
Technical field
The present invention relates to a kind of cage culture method, particularly a kind of inland river, waters, reservoir area of being used for can realize that many kinds culture the fish-cultivating method that can protect environment again, purifies water.
Background technology
In the inland river, to utilize fish culture in net pen be the important component part of China's fishery economic to the waters, reservoir area, especially nearly 10 years, reservoir is greatly developed the cage culture channel catfish, obtained good export economy benefit, but excreta of fish and residual bait also cause certain pollution to water environment, can not realize the purpose of sustainable development.
Summary of the invention
Technical problem to be solved by this invention provides a kind of can the assurance under the situation of existing fish culture effect, protection environment, the fish culture in net pen method that purifies water.
In order to solve the problems of the technologies described above, technical scheme of the present invention is: a kind of method of utilizing fish culture in net pen may further comprise the steps:
(a) the whole skeleton of net cage layout is set according to the situation in inland river, waters, reservoir area, framework is set on skeleton;
(b) large cage is set on framework, in large cage, cultures the filter-feeding economic fish;
(c) the intensive culture net cage is set in large cage, in the intensive culture net cage, cultures the bait throwing in fish.
Described filter-feeding economic fish is bighead and silver carp.
Described bait throwing in fish are channel catfish.
Described net cage layout is " non-" font framework is set by the whole skeleton of " returning " font layout inside and outside the skeleton.
Fish culture in net pen method provided by the invention; according to ecological principle; the solid cover that utilizes the fish of different feeding habits to carry out different water layers is supported pattern; with the upper strata of bait throwing in fish culture at the filter-feeding economic fish; the filter-feeding economic fish promptly can the bait throwing in fish excreta and residual bait be food; reached under the situation that guarantees existing fish culture effect, reduced pollutant discharge amount, the effect of protection environment.The present invention also has the advantage that method is easy to learn, adaptability strong, be easy to promote.
Description of drawings
