Problems solved by technology

Polyethylene (PE) rope and polypropylene (PP) rope have better durability and recyclability, but there is no calcium source in the attachment base, and the egg attachment performance is still low, which is difficult to compare with natural gorgonians
In marine aquaculture, the attachment of fouling organisms will not only reduce the dissolved oxygen in the water environment in the aquaculture facility due to blocking the meshes of cages, cages, seines, etc. Facility drift and wear, as well as a significant increase in external loads lead to a decrease in the buoyancy of the floating body, shortening the service life of the cage, and competing with the cultured objects (shellfish and algae) for attachment substrates and bait, and even directly attaching to the surface of the cultured organisms affects its growth and development. The yield and quality of aquatic products

Embodiment

[0015] Example: refer to Figure 1 to Figure 3 , a hanging cage for squid laying eggs, comprising a cylindrical fine-mesh screen 1 with a support, characterized in that: the fine-mesh screen 1 is suspended with a calcium-coated mesh 6 through a hook 41; the calcium-coated mesh 6 is attached with a synthetic resin rope It is an adhesive base skeleton material; the inside of the synthetic resin rope contains calcium hydroxide or soluble calcium salt; the outside of the synthetic resin rope is coated with a coating containing calcium material, and the coating of the calcium material has a rough surface.

[0016] The coating of calcium-containing materials contains film-forming substances, plasticizers, calcium carbonate, and fillers; the film-forming substances are polyvinyl acetate latex or acrylic latex or acrylic acid resins or epoxy resins; the plasticizer is phthalate Dibutyl formate or dioctyl phthalate; the filler is one or more of 20 mesh to 40 mesh quartz sand, iron oxid...

Abstract

The invention discloses a cuttlefish egg adhesion hanging cage, which comprises a cylindrical fine-mesh screen with supporting parts, wherein a calcium clothing adhesion net piece is hung in the fine-mesh screen, a synthetic resin rope serves as an adherence framework material of the calcium clothing adhesion net piece, calcium hydroxide or soluble calcium salt is contained in the synthetic resin rope, and a coating containing calcium materials is coated outside the synthetic resin rope and is provided with a rough surface. The cuttlefish egg adhesion hanging cage has the advantages of being novel in structure, good in incubation effect, high in incubation rate, good in aquaculture effect and the like.

Description

technical field [0001] The invention relates to a breeding device, in particular to a hanging cage for squid laying eggs. Background technique [0002] Squid, especially Mansoni squid is an important economic fish resource in our country, and it is one of the traditional "four seafood". It has a high output in history. Its meat is delicious and nutritious, and it is deeply loved by the people. . However, since the mid-1970s, due to overfishing and environmental conditions, squid resources have been greatly damaged and have long been exhausted. Investigations and studies have shown that the spawning attachments of Squid mansoni in natural sea areas are mainly gorgonians, macroalgae and artificial discards, of which gorgonians account for more than 60%, artificial discards account for about 30%, and seaweeds account for 10%. About % (Wu Changwen, Dong Zhiyong, Chi Changfeng, etc. Man's needleless squid ( Sepiella maindroni ) breeding habits and the restoration of its spawni...
