Abstract

The present invention relates to a spawning reef of an artificial fishing reef, more specifically a box type cuttlefish spawning reef which is used for a cuttlefish as a proliferation object to spawn. A plastic board is fixedly coated outside a square framework. A plurality of circular holes are arranged in the plastic board, and netting used as spawning attached bases is arranged in the square framework. Each circular hole is corresponding to a spawning chamber which is formed by the spacing of the netting, and the top of each circular hole is sealed by the netting. The plastic board is a PVC white plastic board. A plurality of magnets are fixed at the inner side of the plastic board in consideration of a biological magnetic field effect. The present invention built in this way, fully uses the habits of phototaxis and hole residence and the magnetic field effect. The present invention has the advantages of stable structure, simple manufacture, low cost and convenient management; meanwhile, space is fully used, and a spawning parent can not be damaged.

Description

A kind of inkfish spawning reef

Technical field

The present invention relates to the artificial fish shelter reef of laying eggs, be specifically with the cuttlefish be the propagation object for its reef of laying eggs of laying eggs---plant inkfish spawning reef.

Background technology

Cuttlefish, especially golden cuttlefish are one of important economic siphonopods of China's sea fishery, the main fishing ground of China golden cuttlefish at haze at the sunshine hilltop, Shandong, Qingdao, Huanghai Sea middle part and northern.As far back as nineteen fifty-nine; China Zhu Yuanding professor just proposes will breed and this valuable source of protective money cuttlefish in west of pacific ocean fishery study executive session; but after the last century the eighties; along with the development of fish production and improving constantly of modernization level; golden cuttlefish is faced, and to fish for pressure increasing; the environment and the production order of spawning ground that golden cuttlefish is present and propagation protection zone are on the hazard; the regeneration capacity of its resource is difficult to bear the catching intensity that grows with each passing day; magnitude of recruitment significantly descends, and its fish production is obviously failed.

The landrace of golden cuttlefish conduct-kind of preciousness rose and to be put into Shandong Province's local supplies propagation plan in 1992.What take is a kind of half artificial fecundation protected mode to propagation, and the cuttlefish cage that is about to be attached with golden cuttlefish fertilized egg collects, and concentrates and renders to a Dinghai District, it hatch naturally to breed to protect manage.The enforcement period of the ninth five-year plan, nearly 1,000,000 yuan in coastal infusion of financial resources at sunshine of Shandong Province carry out the propagation of golden cuttlefish and release, and have created favorable economic benefit, though fair with the cuttlefish cage as golden cuttlefish propagation adherance effect, also exist some problems simultaneously.The one, be subjected to the influence of fishery resources, fishing ground environment and productivity effect in recent years, the cuttlefish cage quantity that puts into production sharply reduces, and propagation restricts the outstanding problem that cuttlefish breeds industry and further expansion scale with next former the becoming of adherance; The 2nd, the cuttlefish cage is made complicated, and cost is higher, is unsuitable for the extensive propagation of golden cuttlefish; The 3rd, cuttlefish cage itself is a purpose to fish for, the infringement parent of laying eggs, and the habit that the incompatibility golden cuttlefish repeatedly lays eggs has influenced the egg laying amount of golden cuttlefish.For stable and further enlarge golden cuttlefish propagation scale, improve enrichment procedure, seeking the new golden cuttlefish reef of laying eggs then becomes the important topic that propagation work faces.

Summary of the invention

The purpose of this invention is to provide a kind of inkfish spawning reef, to remedy the deficiencies in the prior art.

Studies show that cuttlefish has phototaxis as golden cuttlefish, have the habit that happiness is got into the cave simultaneously.Practice also shows with the cuttlefish cage breeds adherance as golden cuttlefish, and golden cuttlefish can originate in ovum on the etting.

Basic design of the present invention: be included in the outer fixed packet adularescent plastic plate of framework, can satisfy the become habit of light of golden cuttlefish, this plastic plate is provided with a plurality of circular openings, to satisfy the habit that the golden cuttlefish happiness is got into the cave, and in framework, lay etting as the adherance of laying eggs, and there is etting to bind, it is characterized in that it also is included in PVC white and moulds the plate inboard and be fixed with some magnets, the laying coop that each above-mentioned hole correspondence is made of at interval etting.Above-mentioned etting is the polyethylene etting.

Consider biological magnetic field effect, on the plastic plate inboard, embed and be fixed with some magnets.

The present invention who constructs has thus made full use of habit and the magnetic field effect that the biological light that becomes, happiness are got into the cave, and Stability Analysis of Structures is made simply, and cost is low, and is convenient to management, has made full use of the space simultaneously, and does not damage the parent of laying eggs.

Embodiment

As Fig. 1～5, technical scheme of the present invention is fixedly to be surrounded by plastic plate 2 outside framework 1, and this plastic plate 2 is provided with a plurality of circular openings 3, and lays the etting 4 as the adherance of laying eggs in framework 1, the laying coop that each hole 3 correspondence is made of at interval etting 4, and have a slice etting 4 to bind.Above-mentioned framework 1 is made for the square bodily form or tubular angle steel or pvc pipe, and above-mentioned plastic plate 2 is a PVC white plastic plate.

As Fig. 4, consider biological magnetic field effect, embed in plastic plate 2 inboards and be fixed with some magnets, magnet 5 is a permanent magnet.Consider that simultaneously too weak magnetic field is very little to biological agent, too strong magnetic field intensity can have inhibitory action to biology again, therefore with reference to the correlative study report magnetic field intensity that the magnet on the plastic plate in the laying coop 25 produces is controlled in 50mT～700mT scope.

Be the increase space of laying eggs, but bondage there are 1～2 bundle Chinese tamarisk or artemisia annua 6 long-pending with traction-increasing surface on the etting 4 of each laying coop.On-the-spot sea area is that unit lays with group, 5～8 meters of the every capable individual distances of reef group, and every row is thrown in individual 10～15, every group 3～5 row, in the ranks longitudinal pitch is 100 meters, 500 meters of horizontal spacings.For ease of recycling, when throwing in, each reef of laying eggs can connect-float, and the annual inkfish spawning that arrives is during season, and the reef of will laying eggs is invested in the inkfish spawning sea area; After the spawning season, the reef of laying eggs can be reclaimed clean and use so that continued in 1 year.

The present invention be by angle iron frame outsourcing white plastic plate, in draw in the net clothing, and the reef of laying eggs that etting binds and forms is stamped on top.Consider convenient transportation simultaneously, as Fig. 6, also available pvc pipe 7 is made the square body framework, the white plastic plate of holding hole successfully is fixed on the peripheral pvc pipe 7, by socket connection together, time spent foldable for storage not is during toward marine placement between the tube and tube, to peg graft between the tube and tube, it is shaped in marine expansion.

As embodiment, the said frame structure is a regular cube shape angle steel, specification is the length of side 80～120cm, four sides are surrounded by the thick white PVC plastic plate of 3mm, 5～10cm can be left as the usefulness of laying sinker in the bottom, all has the hole of 5 diameter 15～20cm on every side plastic plate, inner transverse and vertical etting that all is laid with two row's tensions, it is long-pending with traction-increasing surface to be tied with 1～2 bundle Chinese tamarisk or artemisia annua on the etting, and the etting that tension is stamped at the top binds.
