Deep sea cultivation net cage utilizing wave energy

Abstract

The invention discloses a deep seat cultivation net cage utilizing wave energy. The deep seat cultivation net cage comprises an annular support floating rack, a cultivation net cage body, an annular floating rack, an intermittent feeding mechanism and an oxygen supply device and is characterized in that the annular support floating rack floats on the sea surface and is provided with vertical guiderods; the edge of the upper-end opening of the cultivation net cage body is fixed to the annular floating rack; the intermittent feeding mechanism feeds bait into the cultivation net cage body in anintermittent manner; the oxygen supply device supplies oxygen for the bottom of the cultivation net cage body. The deep seat cultivation net cage utilizing the wave energy has the advantages that theintermittent feeding manner is used to prolong feeding time and reduce the bait feeding quantity of each time, and the problems that a large amount of bait sinks to penetrate the cultivation net cagebefore being eaten by fish in the cultivation net cage, severe bait waste is caused, and the large amount of residual bait deposited to the sea bed affects sea bottom soil environments are solved.

Description

technical field [0001] The invention relates to a deep-sea cage culture, in particular to a deep-sea culture cage utilizing wave energy. Background technique [0002] A current type of deep-sea culture net cage is mainly composed of an annular support floating frame, a culture net cage and a fixing device, wherein the annular support floating frame floats on the sea surface; the upper end of the culture net cage is opened, and the edge of the upper end opening of the culture net cage is fixed On the ring-shaped floating frame, the bottom of the cultured cage is lowered to a limited depth underwater by using the gravity of the cultured cage; the fixing device includes a number of counterweights that sink to the seabed and fixed cables connecting the counterweight and the ring-supported floating frame. Used to fix the ring support floating frame. The artificial feeding of present this type of deep-sea culture net cage adopts that the bait is directly dropped on the sea surfac...

AI Technical Summary

Problems solved by technology

[0004] The object of the present invention is to provide a deep-sea culture net cage utilizing wave energy, which adopts intermittent feeding mode for feeding, so as to prolong the feeding time and reduce the amount of bait each time, thereby effectively solving the problem that a large amount of bait is not used. The fish in the cultured cages sink and pass through the cultured cages, resulting in a serious waste of bait and a large amount of residual bait deposited on the seabed, which affects the marine bottom environment.
