Multipurpose netting for mariculture net cage

Abstract

A multipurpose netting for a mariculture net cage relates to mariculture equipment and comprises a top net, a bottom net, a sea cucumber culture attachment base, side nets, net ribs and net cords 7; a middle net 5 is arranged between the bottom net and the top net; an abalone culture habitat base 13 is arranged on the middle net and comprises bird-nest-shaped habitat nests 13 distributed on the middle net and abalone movement porous plates 14 close to the habitat nests; each bird-nest-shaped habitat nest is formed by buckling an arc-shaped buckling cover 16 on a porous base plate 15; and an opening allowing abalones to enter and exit is arranged at the front end of each habitat nest. The netting has the advantages that the bottom net of the net cage is used for farming sea cucumber, the middle net is used for farming abalone, and the space of the net case is fully utilized; two sea products can be farmed in the same cage; and abalone eat plankton like seaweeds, excreta of the abalone is food of sea cucumber, and thus a food chain is formed, so that organic matter resources of sea creatures are fully used, feed given by a human can be saved, culture cost is reduced, and culture benefits are improved.

Description

Technical field: [0001] The invention relates to seawater aquaculture equipment, in particular to multipurpose netting for seawater culture cages. Background technique: [0002] The netting of the existing marine aquaculture cages consists of top nets, bottom nets, side nets, mesh bars, floats, and net cables that tie the netting to the cage frame. The bottom net has an inner layer of breeding nets and an outer layer of protection There are 2 layers of nets, and the side nets have 2 layers of inner breeding nets and outer protective nets. Existing net cages are only used for a single seafood culture, such as only sea cucumbers or sea fish, etc., which will cause a waste of space for the culture cages, and in addition, due to the lack of biological chains in the culture process, the biological organic matter in the sea cannot be fully utilized Resources, can not reach the best breeding benefits. Invention content: [0003] The purpose of the present invention is to provid...
