Bottom-seated net cage suitable for bottom water body aquaculture

Abstract

The invention relates to a bottom-seated net cage suitable for bottom water body aquaculture, which consists of a skid-resistant foundation, a net cage frame, a net body system and a water surface floating body system, wherein the net cage frame and a main cultivation space are located at the bottom layer of seawater, and the middle of the net cage frame and the main cultivation space are connected with the water surface floating body system located on the water surface through a flexible net bag to form a complete cultivation space system. The net cage has flow guiding and flow blocking capabilities, and can effectively reduce the influence of wind waves and sea currents on cultured fishes; the invention can adapt to the sea area environment with poor soil quality and bad sea condition; the netting is convenient to replace and maintain, the working surface can be designed above the water surface, and the added cost of underwater operation is saved; the effective space of the net cageis increased, and the quality of cultured fishes is improved; large-scale and intelligent cultivation can be realized.

Description

technical field [0001] The invention relates to a net cage device for underwater cultivation, in particular to a bottom sitting net cage for bottom water cultivation. Background technique [0002] The development of marine ranching is inseparable from deep-sea cage culture equipment. Deep-sea cage culture equipment involves many engineering issues such as the anti-wave performance of the cage, bait feeding, net cleaning, monitoring and operation convenience. In deep waters, the wind and waves are generally larger. In particular, the East my country Sea and the South China Sea are located in typhoon-prone areas, and the impact of wind and waves on the cage culture system is particularly obvious. The development of deep-sea cages is that Norway, the United States, and Japan are at the forefront of the world. [0003] The main forms of cages in Norway are cylindrical cages made of HDPE and sinkable tension leg cages. The advantages of cylindrical cages are low cost, simple s...

AI Technical Summary

Problems solved by technology

At present, the biggest disadvantages of deep-water cages in my country are poor wave resistance and current resistance. The water flow environment in the cages is not suitable for fish farming, and there is a lack of supporting technology and facilities.
