Soft-frame-type sea-bottom cultivation net cage

Abstract

The invention relates to a soft-frame-type sea-bottom cultivation net cage which comprises a net cage frame and a net connected with the net cage frame in a covering manner, and is characterized in that the net cage frame is a soft frame comprising two float lines, two bottom lines, a top-connected line, an angle drooping line and a plurality of buoys, wherein, the bottom line is fixed at the bottom of the sea bottom by a fixed peg and a fixed rope; the bodies of the two float lines and the two bottom lines are bent at the two corresponding bevel part in pairs; the two ends of the bent body are respectively connected with a terminating part thereof; the terminating part is fixed with the sea bottom by the fixed peg; the top-connected line is respectively connected with line bodies betweenthe bevel part corresponding to the two float lines; the angle drooping line is respectively connected with the line bodies between the two float lines and the corresponding bevel part of the two float lines; the buoys are knotted on the float lines and the top-connected line according to the rated buoyancy; and a net cage soft frame is formed by tensioning and expanding the float lines, the top-connected line, the angle drooping line and the bottom lines by the buoyancy of the buoys. The invention has reasonable structure, strong capacity of tide and ocean current resistance and high safety,and is an ideal seawater aquaculture net cage.

Description

technical field [0001] The invention relates to aquaculture of aquatic products, in particular to a soft-frame seabed culture cage arranged at the bottom of the seabed. Background technique [0002] We know that seawater cage culture is an intensive culture method in large waters. Through the free exchange of water inside and outside the cage, an ecological environment suitable for the growth of cultured objects is formed in the cage. It has the advantages of short breeding cycle and high feed conversion rate. High, convenient operation and management, high output per unit area, high degree of intensification, significant economic benefits and other characteristics, it has broad development prospects. At present, most of the net cages used in public are suspension or floating net cages, which use anchors and sinking frames to fix and float the net cages on the water surface or suspend them in the upper waters of 5-6 meters in water depth. But the water body position that ab...

Problems solved by technology

[0003] In order to overcome the disadvantages of the bottom-planted purse seine cages in the prior art that are weak in resisting tides and ocean currents, and are likely to cause death, injury and escape of breeding objects and affect breeding benefits, the present invention provides a cage with reasonable structure, strong tide and ocean current resistance, and an anti-tidal cage.
