Sea cucumber seabed culture net cage

Abstract

The invention discloses a sea cucumber seabed culture net cage. The problem that bait supply in the net cage is uneven due to the fact that the bottom of the net cage is far away from the seabed through an existing holothurian culture net cage supporting leg is solved. The net cage comprises a net cage frame, a netting and a substratum, wherein the net cage frame comprises an upper supporting pipe ring, a lower supporting pipe ring and a vertical connecting pipe; the invention is characterized in that the top end of the vertical connecting pipe is closed, the bottom end of the vertical connecting pipe is open and extends to the lower portion of the lower supporting pipe ring to form a supporting leg, a plurality of suction holes are formed in a pipe body, close to the bottom end, of the vertical connecting pipe, and an exhalation hole with a one-way valve is formed in a pipe body, between the upper supporting pipe ring and the lower supporting pipe ring, of the vertical connecting pipe; and a water surface floating body is arranged on the net cage frame. During use, an air cavity is formed between the exhalation hole and the top end of the vertical connecting pipe, when the net cage floats upwards, seabed sediment mixture is sucked through the suction inlet due to negative pressure in the vertical connecting pipe, when the net cage sinks, the sediment mixture in the vertical connecting pipe is sprayed out through the exhalation one-way valve and fed into the net cage, and sea cucumber bait is evenly supplied into the net cage.

Description

technical field [0001] The invention relates to the cultivation of sea cucumbers, in particular to a net cage for sea cucumber cultivation on the seabed. Background technique [0002] We know that sea cucumber is an echinoderm, which ranks first among the eight delicacies of seafood. It is rich in nutrition and has high food value and medical value. With the improvement of people's living standards and the continuous reduction of natural sea cucumber resources, the production of wild sea cucumbers has been difficult to meet people's needs, and the artificially cultured sea cucumber industry has developed. Traditional sea cucumber farming methods mainly include pond culture, tidal zone cofferdam culture, shallow sea cage culture and industrial greenhouse culture, etc. These traditional sea cucumber culture methods have artificially transformed the sea cucumber growth environment and affected the quality of sea cucumbers. Due to the abundance of natural baits such as organic ...

Problems solved by technology

[0003] In order to solve the problem that the support feet at the bottom of the existing sea cucumber breeding net cage keep the bottom of the net cage away from the seabed silt and easily cause the uneven supply of sea cucumber bait inside the net cage, the purpose of the present invention is to provide a kind of pump that can suck the bottom of the seabed silt and tiny Biological and net cage sea cucumber bait supply uniform sea cucumber subsea culture net cage
