Abstract

The utility model relates to an octopus laying reef which comprises at least one PVC tube, more than two small holes are distributed on the tube, one end of the PVC tube is closed by a netting sheet, and a rope with the upper end provided with a bobber is tied on the PVC tube. A concrete layer that the perfusion thickness of the PVC tube on the bottom layer of a compound reef body which is formed by overlapping a plurality of PVC tubes closed by netting sheets is less than the radius of the PVC tubes is taken as a sinker. The reef can be manufactured simply, the weight is lighter, after being thrown, the reef can be taken out at any time for watching the ovum-attaching effect, and a good ovum collecting device can be provided for artificial incubation in an octopus room; the PVC material can not cause bad effect on the ocean environment, and the reef provides a good laying reef of an ovum laying attachment base for the octopus, and the effects of collection and proliferation of the octopus are obvious.

Description

A kind of octopus reef of laying eggs

Technical field

A kind of good octopus that lays eggs, hatches place reef of laying eggs that provides is provided the utility model.

Background technology

Octopus is coastal widely distributed in China, and northern marine site mainly contains short octopus and long octopus, and its delicious meat is of high nutritive value, and the domestic and international market is wide.Along with the excessive utilization of cuttlefishes resource, octopus has become one of economic siphonopods that the northern China coastal waters mainly utilizes, because of overfishing and Ecological environment worsening, and wild octopus a resource shrinkage.The octopus life cycle is short, and growth is a kind of economic kind of culturing potentiality that has very much rapidly, and the octopus cultivation of China relies on natural fishing for fully because of seed at present, does not form industrialization as yet.Discover that octopus lay eggs need be attached on other attachments for sticking together gamogenetic egg, the rich apology of octopus resource depends primarily on the height that how much reaches survival rate of its egg laying amount again.Therefore, provide the reef of laying eggs, lure collection and ensure that octopus lays eggs, and make the octopus ovum obtain child care, hatch and prevent harmful animal, improve the survival rate of young postlarva, propagation and recovery octopus resource are very important as its ovum adherance.

Summary of the invention

The purpose of this utility model provides a kind of with low cost, simple and convenient octopus reef of laying eggs, to remedy the deficiencies in the prior art.

Another purpose of the present utility model is the ova collection device of growing seedlings and providing necessary for octopus cultivation artificial incubation, thereby accelerates total man's workerization breed of octopus.

A kind of octopus reef of laying eggs is characterized in that it comprises at least one pvc pipe that is laid with two above apertures on it, and an end of every pvc pipe has the sealing of net sheet, and the rope that has a upper end to have float ties up on the pvc pipe.

The pvc pipe perfusion thickness of one deck of the end of the above-mentioned compound reefs that is formed by stacking with the pvc pipe of net sheet sealing by several ends is less than the concrete layer of pvc pipe radius as sinker.

The utility model adopts the familiar PVC pipe, make simple, weight is lighter, both can get at any time after the input and observe attached ovum effect, also can provide good ova collection device for the hatching of octopus indoors artificial, used PVC material can not cause harmful effect to marine environment, is a kind of for octopus provides the reef of laying eggs of the good adherance of laying eggs, and it lures collection and propagation octopus effect obvious.

Description of drawings

Fig. 1 main TV structure schematic diagram of the present utility model.

Fig. 2 compound reef perspective view of the present utility model.

Monomer reef (single pvc pipe) structural representation of Fig. 3 basic structure of the present utility model.

Wherein: 1. float, 2. rope, 3.PVC pipe, 4. aperture, 5. concrete layer, 6. net sheet.

Embodiment

As Fig. 1-3, the utility model comprises at least one pvc pipe 3 that is laid with two above apertures 4 on it, and an end of every pvc pipe 3 has 6 sealings of net sheet, and the rope 2 that has a upper end to have float 1 ties up on the pvc pipe 3.

As Fig. 2, the pvc pipe 3 perfusion thickness of one deck of the end of the above-mentioned compound reefs that is formed by stacking with the pvc pipe 3 of net sheet 6 sealing by several ends are less than the concrete layer 5 of pvc pipe radius as sinker.As the utility model can be measure-alike by several, offside opens the compound reefs that aperture 4, an end are formed by stacking with the pvc pipe of net sheet 6 sealings, an and rope 2 that has float that is connected in its middle and upper part pvc pipe 3; Be less than the concrete layer 5 of pvc pipe radius as sinker at one deck perfusion thickness of the end of compound reef again.Simultaneously can stop bottom silt in pvc pipe 3, to be invaded again.For strengthening luring the collection effect, can in pvc pipe 3, place an amount of fresh and alive oyster before actual the input.

Wherein the yardstick of aperture 4 is suitable for octopus to bore the size in cave mutually.This is based on the ecological habit that octopus hobby is bored the cave, opens aperture 4 in pvc pipe 3 both sides and both can lure the collection octopus to enter wherein to lay eggs, can increase the utilization ratio of reef inner space of laying eggs again, thereby play the good collection effect that lures.

As the monomer reef of Fig. 3, comprise that mainly two middle side parts open the pvc pipe 3 of aperture 4, and be used to seal the net sheet 6 of pvc pipe one end as the basic structure of the utility model.End at pvc pipe 3 is sealed with net sheet 6, not only can hide harmful animal, also can trap be set for the octopus forage, keep simultaneously laying eggs in the reef logical light and current is unobstructed, provide good environment for octopus lays eggs to hatch, thereby improve octopus output effectively, reach the purpose of propagation and recovery octopus resource.

As Fig. 2, basal plane is long-pending in order to enlarge, the gathering effectiveness of a plurality of monomer reefs of performance, and a plurality of monomer reefs are superimposed in order, can increase the utilization ratio of compound reef inner space like this.During use,, need to connect float 1 thing as a token of with a rope 2 for being convenient to folding and unfolding at any time.

Obviously, the utility model can be the reef of laying eggs that octopus, cuttlefish etc. provide the good place of laying eggs, hatching.

Claims
