A lantern-shaped collapsible golden squid spawning reef

Abstract

The invention provides a lantern-shaped foldable golden squid spawning reef, which includes a cable and several lantern-shaped spawning reef units suspended on the cable, and floating balls are arranged at both ends of the cable; the lantern-shaped spawning reef The unit includes a lantern-shaped frame and a net covered on the lantern-shaped frame; the lantern-shaped frame is composed of four semicircular tube frames and fixed straps; the semicircular tube frame is composed of a fixed central axis and a semicircular The fixed central axis is a quarter cylinder, and the two ends of the semicircular tube are fixed to the two ends of the fixed central axis; the fixed cable ties fix the four semicircular tube frames together , forming a lantern-shaped frame; the upper end of the fixed axis has a small hole, and the rope passes through the small hole to vertically tie the lantern-shaped spawning reef to the cable. The spawning reef provided by the invention is lantern-shaped, has relatively small flow resistance, high space utilization rate, smooth structure, large hatching area, does not cause any damage to the spawning body, and is very convenient to disassemble 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...

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
