Embodiment Construction

[0019] The present invention will be further described below in conjunction with the examples, but not as a limitation of the present invention.

[0020] The cage-based three-dimensional culture method of American California perch-spoonbill sturgeon-water hydrangea is operated according to the following points:

[0021] A. Set up deep water cages

[0022] Deep-water net cage (hereinafter referred to as net cage) is the deep-water polyculture net cage disclosed in Chinese patent document CN203851609U. The net cage is arranged in the deep water area of ​​freshwater waters, and the water depth is too shallow. For outflow, the water depth is generally better than 3m; the water flow is smooth, the water quality is fresh, the backwater bay is sheltered from the wind and the sun, and the flow velocity is within the range of 0.05-0.2m / s and the wind force does not exceed level 5; place.

[0023] B. Water Quality Management

[0024] Infuse fresh water in an appropriate amount every ...

Abstract

The invention discloses a California perch, paddlefish and water spinach stereoscopic culturing method based on net cages. California perches, paddlefish and water spinach are subjected to organic combination of symbiotic breeding and planting, and the stereoscopic ecological culturing mode that the water spinach is planted on the water surfaces of the deep water net cages, the paddlefish is cultured in the upper middle layer of a water body, and the California perches are cultured in the lower middle layer of the water body. By means of the method, the culturing production potential of the net cages is fully dug, the space of the water body is fully utilized, the output rate of unit area is effectively increased, and the problem of tail water pollution brought by the current aquaculture process can be well solved.

Description

technical field [0001] The invention relates to a three-dimensional culture method for fish and aquatic plants, in particular to a net cage-based three-dimensional culture method for California perch-surger-surgeon-wateryam, and belongs to the technical field of aquatic product culture. Background technique [0002] South China has vast waters and many freshwater waters. However, due to the different ecological environment and geographical structure of the waters, most of the waters themselves are not completely suitable for aquaculture, resulting in a great waste of water resources. The use of net cages to establish artificial ecological breeding systems for aquatic animals and plants can break the boundaries of traditional artificial breeding requirements for water areas, and make full use of a large number of water resources that were originally unavailable for fishery production. In addition, in the traditional freshwater cage culture species, it is generally common to r...
