Embodiment 1

[0016] Connect the fixed frame 1 that the small net cage 4 usefulness of square eel inhabits with many 1.0 meter fixed rods 5, small net cage 4 is connected equidistantly by four fixed frames 1 with ropes, each small net cage 4 uses The distance between the fixed frames 1 is all 0.5 meters, and each fixed frame 1 is tightened as the fish-carrying layer 7 with non-woven fabric, and it is the eel passage hole that the diameter is 0.04 meters on the non-woven fabric.

[0017] Be connected into the fixed frame 1 that square anti-eel escapes large net cage 3 usefulness with many fixed rods 5 of 1.5 meters. Large net cage 3 has two fixed frames 1, wherein a fixed frame 1 is tightened as a fish-carrying layer 7 with non-woven fabric, and the sides of two fixed frames 1 are closed with a fishnet with a maximum circular aperture of 0.01 meter, so that the eel-proof Fish escape big net cage 3 and become only one side opening other five sides are the big net cage 3 that the maximum circu...

Embodiment 2

[0023] As embodiment 1, only be that the fixed frame 1 of four fish-carrying layers 7 of small net cage 4 is that the fishnet of 0.04 meter or the non-woven fiber cloth of circular aperture are closed into the net cage wall that water can flow freely.

Embodiment 3

[0025] As embodiment 1, only the fish net 2 of the fish-carrying layer 7 is used without the non-woven fiber cloth of hole. Others are the same as in Example 1.

Abstract

This invention relates to the field of cultivation, especially it is a kind of net cage for intensive culturing sillagos in water. In order to meet to the environment need of sillagos physiology, a smaller net cage 4 with taking several sillagos layers 7 is set in a bigger net cage 3 that is used to prevent the sillagos from escaping, and the largest net hole diameter of the net cage 3 is smaller than the body diameter of the smallest sillagos, and the sillagos layers 7 can be made of fishnet or non-slub fabric or others. The sillagoses can inhabit on any sillagos layer 7 according to their living needs, especially they can stay on the topside to breath. This invention provides a cultivation equipment matches with sillagos living characteristics. In the net cage, sillagoses can inhabit in places of different water depth and different water temperature. This equipment can be used in reservoir or river to intensive culturing sillagoses, and cultivation and catching is convenient, survival rate and output is high.

Description

technical field [0001] The invention relates to the technical field of cultivation, in particular to a net cage for intensive cultivation of eel in water. Background technique [0002] Because of the physiological structure without fins and floats, it is difficult for eels to stay in the middle of the water for a long time. They can only stop for a long time and carry out normal life in mud holes with physical entities that support the eel's body, such as pools or pool walls. and reproduce. In the prior art, intensive cultivation of eel does not solve the problem that eel stays in the middle layer of water for a long time, and there are many studies on the composition of bait. Chinese patent 98229432.8 discloses a water tank type "eel breeding box". This eel breeding box consists of a box body, a box cover, and fillers. The bottom of the box body is made of bricks; the bottom layer of the filler is The straw layer, the second layer is a paper laye...
