Ecological breeding net cage for cocultivation of sea cucumbers and sea urchins

Abstract

The invention provides an ecological breeding net cage for cocultivation of sea cucumbers and sea urchins and relates to a mariculture net cage technology. The net cage consists of a net cage frame and a net, wherein the net cage frame comprises a buoyance riser, an upper transverse connecting pipe, a lower transverse connecting pipe, a second lower transverse connecting pipe, a bottom anchor, an air pipe and a net cage self-balancing lifting up-and-down mechanism; the net comprises a top net, a bottom net and a side net; sea cucumber growing attachment bases are arranged on the bottom net; a middle supporting net is arranged in the net cage; sea urchin growing attachment bases are arranged on the middle supporting net; each sea urchin growing attachment base is a plate which is rectangular according to overhead view; through holes are formed on the plate; and an inclined flow baffle vertical plate is arranged at one end of the plate. The ecological breeding net cage for cocultivation of the sea cucumbers and the sea urchins has the benefits that the bottom net is used for breeding the sea cucumbers, the middle supporting net is used for breeding the sea urchins, the two marine products are bred in the same net cage, the sea urchins eat pelagic organisms such as algae and the like in water, and the excrement of the sea urchins provides part of food for the sea cucumbers, so that a food chain is formed, the biological organic matter resources in seawater are utilized completely, feed is saved, and the breeding cost is saved; the marine products with high nutritional value, economic value and medical value are obtained; and the breeding benefit of the net cage is greatly increased.

Description

Technical field: [0001] The invention relates to seawater aquaculture equipment, in particular to a seawater ecological aquaculture cage with multiple cultivations in one box. Background technique: [0002] Existing marine aquaculture cages are only used for single seafood cultivation. For example, the current marine aquaculture cages are mainly for cultivating sea cucumbers. The biological organic matter resources in the sea cannot be fully utilized, and the best breeding benefits cannot be achieved. Invention content: [0003] The purpose of the present invention is to provide a kind of ecological breeding net cage for sea cucumber and sea urchin co-cultivation, which overcomes the poor economy and resource waste of single species cultivation, realizes multiple cultivation in one case, and fully utilizes the resources of net cage facilities and fully utilizes The biological chain effect, in order to achieve the best breeding income. [0004] The purpose of the above in...
