no. 1 example

[0028] Such as Figure 1a with 1b As shown, the cage 1 of this embodiment includes a cage body 10 , a drainage hose 60 , a rigid frame 90 and a floating body frame 11 . The four sides and the bottom of the cage body 10 are formed by impermeable heat-insulating cloth, and the top is open so as to form a chamber for fish farming. The bottom of net box body 10 is formed with drainage hole 50, and anti-fish escaping net (not shown) can be set on drainage hole 50. One end of the drain hose 60 is connected to the drain hole 50, and the other end 80 of the drain hose 60 can be placed under the water surface or extend out of the water surface. A rigid frame 90 is arranged below the bottom of the net box body 10, and the bottom of the net box body 10 is tied with the rigid frame 90 by ropes, so that the bottom of the net box body 10 is opened. The floating body frame 11 is arranged on the net cage body 10, and the two ends of a plurality of force lines (rib line) 20 are respectively ...

no. 2 example

[0037] For the convenience of operation and management and the rationality of the layout of the water distribution system, as shown in Figure 4a, the fish farming cage system 2' includes a plurality of cage groups 140, and each cage group 140 includes a plurality of cages 1 and At least one water pump 12 . The pipeline arrangement between the water pump 12 and the net cage 1 in each net cage group 140 of the fish farming net cage system 2' is substantially the same, and only one net cage group 140 is taken as an example below to illustrate the relationship between the water pump and a plurality of net cages 1. piping arrangements between them.

[0038] In the cage group 140, the water pump 12 outputs the water body through the main pipeline 122, and the main pipeline 122 communicates with the first sub-pipe 124 and the second sub-pipe 124 respectively, and communicates with a plurality of branch pipes 128 on the first sub-pipe 124, and the water pump 12 outputs The water body...

no. 3 example

[0040] The difference between the fish culture cage system 2 "and the fish culture cage system 2' is that each cage group 140 includes two first sub-pipelines 124, and each sub-pipeline 124 is respectively provided with a plurality of branch pipes 128, The fish culture net cage system 2 " of the present embodiment is suitable for the bigger net cage 1 of volume.

Abstract

The invention provides a cage culture method, a cage and a system comprising the cage. The periphery and the bottom of the cage adopt water-proof thermal-insulating cloth with certain strength; the top part is opened, a drainage hole is arranged at the bottom of the cage; a water distribution system is arranged above the cage, and the entire cage is arranged in the water; low-temperature water is pumped by a pump from the deep part of the lake through the water distribution system, and the water flows into the cage from the upper part of the cage; the water in the cage is cooled or heated up to ensure proper temperature for the normal growth of fish which needs different temperatures; in addition, a mesh bag is arranged inside the cage for catching the fish, and thereby, the fish can be caught and lifted up easily.

Description

technical field [0001] The invention relates to a method and a device for raising fish in a net cage and a system including the device, in particular to a method for raising fish capable of regulating the temperature of water in a net cage, a device and a system including the device. Background technique [0002] Sturgeon is cartilage and hard scale fish, which is widely distributed in Xinjiang, Heilongjiang, Yellow River, Yangtze River, Pearl River and other rivers and their connected lakes and shallow seas. Its value is known as "black gold", especially the caviar processed from sturgeon roe, which is well-known both at home and abroad. Its meat and eggs contain extremely high protein, and the skin can be made into glue. The stomach, intestines, and fish tendons are all top-quality delicacies, and its whole body is treasured. With the reduction of its wild resources, artificial breeding and artificial breeding have been carried out one after another. The species that hav...
