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 high-efficiency breeding method of bluegill sunfish, red bream and Yongcai is operated according to the following points:

[0021] A. Set up deep water cages

[0022] The deep-water net cage is the deep-water polyculture net cage disclosed in Chinese patent document CN203851609U. The deep-water net cage is arranged in the deep water area of ​​the freshwater waters, and the water depth is too shallow. Above 3m is better; the water flow is smooth, the water quality is fresh, sheltered from the wind and facing the sun, and the water area where the flow velocity is within the range of 0.05-0.2m / s and the wind force does not exceed level 5 is better.

[0023] B. Water Quality Management

[0024] Infuse fresh water in an appropriate amount every 2 weeks, and the water change volume is 3 to 5 cm of the height of the...

Abstract

The invention discloses a crapet arlequin-erythroculter ilishaeformis-water spinach efficient culturing method based on net cages. Symbiotic planting and culturing organic combination is conducted on crapet arlequin, erythroculter ilishaeformis and water spinach, and the efficient ecological culturing mode that in deep-water polyculture net cages, the water spinach is planted on the water surface, the erythroculter ilishaeformis is cultured on an upper middle layer of a water body, and the crapet arlequin is cultured on a lower middle layer of the water body is formed. According to the crapet arlequin-erythroculter ilishaeformis-water spinach efficient culturing method based on the net cages, the production potentiality of net cage culture is fully tapped, the water body space is fully utilized, the output rate of unit area is effectively increased, and the tail water pollution problem caused in the current aquaculture process can be well solved.

Description

technical field [0001] The invention relates to a three-dimensional ecological and high-efficiency breeding method for fish and aquatic plants, in particular to a net-cage-based three-dimensional breeding method for bluegill sunfish-red scallops-yellow crayfish, which belongs to the technical field of aquatic product cultivation. 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 ...
