Buoyant-raft net cage sea cucumber culture device and sea cucumber culture method

Abstract

The invention discloses a buoyant-raft net cage sea cucumber culture device and a sea cucumber culture method. The device comprises a floating ball, a buoyant raft hanging rope and a net cage, wherein two ends of the buoyant raft hanging rope are connected with the floating ball; the net cage is connected with the buoyant raft hanging rope via a lifting rope; the floating ball is connected with a wood pile fixed on the seabed respectively by steady lines; and the buoyant raft hanging rope is long enough to cause the net cage to touch the seabed. In the culture device, because the floating ball is fixed by the steady lines connected with the wood pile fixed on the seabed and the net cage is fixed on the seabed in the culture process, influence on the culture system because of ocean current and sea water fluctuation can be effectively lowered, which is more favourable for the sea cucumber to grow. In the culture process, technicians can pull or put down the net cage by the buoyant raft hanging rope; the buoyant-raft net cage sea cucumber culture device is convenient to operate, effectively lowers culture cost and improves economic benefit.

Description

technical field [0001] The invention relates to a sea cucumber culture technology, in particular to a sea cucumber culture device and a corresponding sea cucumber culture method in a floating raft net cage obtained by improving existing culture tools. Background technique [0002] Sea cucumber is an echinoderm, which ranks first among the eight delicacies of seafood and is rich in nutrition. According to research, sea cucumbers, especially northern spiny sea cucumbers, have the characteristics of high protein, low fat, and low sugar, and have 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. The artificially cultured sea cucumber industry has been developed. At present, sea cucumber culture mainly adopts several forms such as nursery room culture, captive culture, shallow sea cage culture and shal...

AI Technical Summary

Problems solved by technology

[0004] ②The breeding cycle is long, and it usually takes 2-3 years or even longer to grow from the seedling stage to the ginseng stage;

[0005] ③Constrained by the environment and other factors, seawater fluctuates greatly, which is not conducive to the stable growth of sea cucumber;

[0006] ④ Poor natural regulation of the environment, high incidence of sea cucumbers, and high risk of breeding

[0007] With the development of society, the scale of sea cucumber farming continues to expand, and the coastal farming area continues to shrink, the existing farming technology has gradually failed to meet people's needs, especially the gradual increase in marine pollution incidents, people began to favor green environmental protection , low-carbon and energy-saving aquaculture technology, so the development of sea cucumber cultivation in middle and deep sea areas (15-40m) has become an inevitable trend
