Zusammenfassung: | The invention discloses a submergence lifting net cage comprising a submergence net cage body provided with a rigid main frame, wherein a prismatic floating frame is connected to the upper part of the main frame; a closed mesh is connected to the inner side of the submergence net cage body; a traction cable is connected to the lower side of the rigid main frame; the traction cable is further connected with a self-submergence base provided with a coiling and uncoiling control component; the coiling and uncoiling control component can be used for controlling the distance between the self-submergence base and the rigid main frame by coiling and uncoiling the traction cable according to needs. The coiling and uncoiling control component is used for coiling and uncoiling the traction cable to control the distance between the self-submergence base and the rigid main frame in order to harvest and breed commercial fish according to demand. The outer side of the rigid main frame is connected with an anchor rope through the traction cable to form an array system for facilitating management. The invention has the advantages of needing no counterweight system, and being convenient to manage, good in wave and current resistance, constant in aquatic water volume and suitable for breeding middle and lower fishes. |
