Problems solved by technology

First, due to the impact of fishery resources, fishery environment and production efficiency in recent years, the number of squid cages put into production has decreased sharply, and the source of attachment substrates for multiplication has become a prominent problem restricting squid multiplication and further expansion of scale; second, the production of squid cages is more complicated , and the cost is high, it is not suitable for the large-scale proliferation of golden squid; the third is that the squid cage itself is for fishing, which damages the spawning broodstock, and is not suitable for the habit of multiple spawning of golden squid, which affects the spawning amount of golden squid

Embodiment Construction

[0016] Such as Figure 1~5 , the technical scheme of the present invention is to be fixedly wrapped with plastic plate 2 outside frame 1, and this plastic plate 2 is provided with a plurality of circular holes 3, and is laid in frame 1 as the net clothing 4 of laying eggs attachment base, each Hole 3 corresponds to the spawning chamber formed by net clothing 4 intervals, and a piece of net clothing 4 is capped. The above-mentioned frame 1 is made of square or cylindrical angle steel or PVC pipe, and the above-mentioned plastic plate 2 is a PVC white plastic plate.

[0017] Such as Figure 4 , considering the biological magnetic field effect, a number of magnets are embedded and fixed inside the plastic plate 2, and the magnet 5 is a permanent magnet. Considering that too weak magnetic field has little effect on organisms, and too strong magnetic field intensity can inhibit organisms, so referring to relevant research reports, the magnetic field intensity produced by magnet 5...

Abstract

The present invention relates to artificial fishing rock, and is especially box-type inkfish spawning reef for inkfish to spawn. The box-type inkfish spawning reef includes rectangular frame, white PVC plastic boards outside the frame and with circular holes, and nets inside the frame to constitute spawning rooms, and magnets fixed inside the plastic boards to produce biological magnetic field effect. The present invention has the phototaxis and hole entering characteristic of jellyfish and magnetic field effect utilized, and has the features of stable structure, simple making, low cost, easy management, etc.

Description

Technical field: [0001] The invention relates to an artificial fish reef spawning reef, in particular to a spawning reef with squid as a multiplication object for its spawning—a squid spawning reef. Background technique [0002] Squid, especially golden squid is one of the important economic cephalopods in my country's marine fishery. The main fishing grounds of my country's golden squid are in Lanshantou, Qingdao, central and northern Yellow Sea, Rizhao, Shandong. As early as 1959, Professor Zhu Yuanding of my country proposed at the meeting of the Western Pacific Fisheries Research Committee to multiply and protect the important resource of golden squid. However, after the 1980s, with the development of fishery production and the continuous improvement of modernization, The fishing pressure faced by the golden squid is increasing. The environment and production order of the current spawning grounds and multiplication protection areas of the golden squid have been threatened...
