Problems solved by technology

However, the rigidity of the above-mentioned chemical fiber nets is low, and it cannot give sufficient shape retention and setting stability to the culture cages. Due to currents, tides, waves, etc., seawater cages are prone to rapid volume changes and swings, and the fish raised are affected. Overstimulation, hindering its growth and development

Embodiment Construction

[0021] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0022] As shown in Figure 1, the present embodiment provides a kind of method that utilizes net cage to cultivate finless porpoise, and described net cage comprises metal frame 1 and the box body 2 that two independent net clothes that are juxtaposed side by side are surrounded, and between box body 2, walk with people. The plank road 3 is connected, the frame 1 is provided with a buoyancy device 4, the bottom four corners of the box body 2 are provided with sinkers 5, and the net cage is provided with a fixing device 6 around it.

[0023] In the above technical solution, the box body 2 adopts 60 strands of soft nylon net, the net is 10m long, 10m wide, 5m deep, and 6cm in mesh, or the net is 10m long, 10m wide, 7m deep, and 8cm in mesh. , the two side-by-side boxes 2 are connected with a 1.2m wide walkway 3; the frame 1 is 8cm angle steel welded to a r...

Abstract

The invention relates to the aquaculture field and provides a method for culturing cowfishes by using a net cage. The net cage comprises a metal frame and two paratactic cage bodies formed by independent nets in an enclosing way. The cage bodies are connected through a pedestrian road. The frame is provided with a floating device. Sinkers are arranged at the four corners of the bottom of each cage body. Fixing devices are arranged around the net cage. The method comprises the following steps of: adopting a method matching voice driving with seining to catch the cowfishes; adopting a semidry transportation method to deliver the cowfishes; adopting a field temporary culture and artificial feeding method to domesticate the cowfishes to adapt to the culture environment of the net cage; and conducting net cage culture and daily cleaning management. The method can resist the influences of water flows, tides, waves and the like, can maintain the shape retentivity and the setting stability ofthe culture net cage and can help the cowfishes grow and develop.

Description

technical field [0001] The invention relates to the field of aquaculture, in particular to a method for cultivating finless porpoises in net cages. Background technique [0002] With the increase of various human activities, such as building dams on rivers, reclamation of lakes, transportation and coastal engineering, etc., the living space of aquatic animals has been greatly occupied, migration channels have been cut off, habitats have been severely damaged, and living conditions have continued to deteriorate. As a result, the degree of endangerment of aquatic animals in our country has continued to increase. It is estimated that the number of endangered wild aquatic animals in my country increases by about 20 species per year on average. The Yangtze finless porpoise is a second-class protected animal in my country. It only lives in the main stream of the middle and lower reaches of the Yangtze River and Poyang Lake and Dongting Lake. The current population is only about 1...
