Lantern-shaped foldable sepia esculenta spawning reef

Abstract

The invention provides a lantern-shaped foldable sepia esculenta spawning reef which comprises a mooring rope and a plurality of lantern-shaped spawning reef units. The lantern-shaped spawning reef units are suspended on the mooring rope, and float balls are arranged at two ends of the mooring rope; the lantern-shaped spawning reef units comprise lantern-shaped frames and netting, and the nettingis coated on the lantern-shaped frames; each lantern-shaped frame comprises four semicircular pipe frames and fixing tying straps; the semicircular pipe frames comprise fixing center shafts and semicircular pipes, each fixing center shaft is a quarter of a cylinder, and two ends of each semicircular pipe are fixed to two ends of the corresponding fixing center shaft; every four corresponding semicircular pipe frames are fixed to one another by the aid of the corresponding fixing tying straps to form each lantern-shaped frame; small holes are formed in the upper ends of the fixing center shafts, and ropes can penetrate the small holes, so that lantern-shaped spawning reefs can be perpendicularly tied on the mooring rope. The lantern-shaped foldable sepia esculenta spawning reef has the advantages that the lantern-shaped spawning reefs are small in adaptive streaming resistance, high in space utilization rate, smooth and soft in structure and large in hatching area, spawning parents canbe prevented from being optionally injured, and the lantern-shaped foldable sepia esculenta spawning reef is quite convenient to detach and assemble.

Description

technical field [0001] The invention relates to the technical field of artificial fish reefs, in particular to a lantern-shaped foldable golden squid spawning reef. Background technique [0002] Golden squid (Sepia esculenta), also known as cuttlefish and mullet, belongs to Cephalopoda, Sepia order, Sepiaidae, and is a wide-temperate migratory species. It likes to lay eggs near islands with a water depth of 5-10 meters, high salinity, clear water, slow flow, hard bottom, and dense algae reefs. They have sandblasting and burrowing habits during spawning, and their parents die one after another after reproduction. Golden squid is widely distributed in the Russian Far East Sea, Honshu, Shikoku, and Kyushu in Japan, the west coast, south coast of North Korea, and the waters of the Philippine Islands. In my country, it is mainly distributed in Lanshantou, Qingdao, and the central and northern parts of the Yellow Sea in Rizhao, Shandong. It has a short life cycle, fast generation...

AI Technical Summary

Problems solved by technology

[0004] Although the effect of using squid cages as a spawning base is good, the squid cage itself is for fishing purposes, which is easy to damage the spawning broodstock, and is not suitable for the habit of golden squid spawning multiple times, which affects the spawning amount of golden squid; and the squid cage is complicated to make. , the high cost is not suitable for the large-scale proliferation of golden squid

[0005] Patent CN104054612A discloses a cross-shaped foldable golden squid spawning reef. The spawning reef is easy to assemble and disassemble. Its disadvantage is that the attachment space angle of the reef body for fish spawning is relatively single, and it is limited to vertical attachment. Spawning, low assembly and disassembly, and inefficient use of space
