Abstract
The utility discloses a device for ooctopus ocellatus to lay egg and incubate is a net cage body with the aperture of 1-2cm, wherein a net rope is arranged above the device; the diameter of a net port is 20-30cm; the middle diameter is 50-60cm and the bottom diameter is 40-50cm; the net cage body comprises a silk net and a bracket; and an egg taking device is arranged in the net cage body. The device can be used for mutually isolating parent ooctopus ocellatus for laying egg, is beneficial to synchronous development and incubation of parent protective eggs and oosperms, avoids the phenomenon that other ooctopus steal food of egg crowds and parent octopus tussle due to striving for habitats, greatly improves the incubation rate of juvenile, can be fully utilized to culture a water body, improves the culture density and is an important technical support for scale culture of ooctopus ocellatus.
Description
Technical field
The utility model relates to the device of a kind of aquaculture field ocean siphonopods seed hatching usefulness, relates in particular to a kind of true octopus used device of hatching of laying eggs.
Background technology
True octopus belongs to Mollusca, Cephalopoda, Octopodida, octopus section, is cosmopolitan, belongs to medium-and-large-sized octopus, and growth is rapid, egg laying amount big (ten thousand/of 10-60).Because export states such as Japan and Korea S in a large number, the original natural resources of China fails because of seriously fishing for.Artificial culture is protection and the effective means that increases stock number with releasing, and has urgency and realistic meaning.True octopus fertilized egg is in hatching process, and close octopus has the ovum of protecting characteristic, and therefore habitat and hatching place by fight protection oneself each other need prevent from by other octopus fertilized egg to be eaten up.Under the artificial environment, the suitable hatching apparatus of laying eggs can guarantee to obtain a large amount of grow healthy and synchronous seeds, and this is the important support of factorial seedling growth success.Have not yet to see the lay eggs report of hatching equipment therefor of relevant true octopus.
Summary of the invention
The purpose of this utility model provides a kind of true octopus used device of hatching of laying eggs, and it can satisfy the demand of prior art.
A kind of true octopus is laid eggs and is hatched used device, it is characterized in that having a cylinder mould body, and there is nettle the top; The network interface diameter of cylinder mould body is 20-30cm, and the middle part diameter is 50-60cm, and base diameter is 40-50cm; The cylinder mould body is configured to propping up by tulle, and the aperture of net is 1-2cm.Adorn one in the described cylinder mould body and adopt egg apparatus.
Advantage of the present utility model is: adopt adopting egg apparatus and can forming the artificial spawning field of diameter and moderate length 1., lay eggs for true octopus and to give security, not only satisfy the true octopus biology demands such as protecting ovum of laying eggs, and the production operation, particularly ovum group easily collecting and embryonic development be convenient in the factorial seedling growth process are easily observed; 2. can effectively parent be isolated from each other, make it under security context, protect ovum, avoid mutually fight and influence the growth of ovum, can prevent that also other octopus from eating its fertilized egg steathily, can under artificial environment, obtain a large amount of grow healthy and synchronous seeds, improve incubation rate greatly; 3. this device is the beads shape and is suspended on lower floor in the pond, can improve the water body utilization ratio, increase parent density, cultivate the metabolic waste of parent simultaneously and fall at the bottom of the pond, be easy to cleaning, guarantee the water body cleaning, for next step seed rearing has been laid solid foundation.
Description of drawings
Accompanying drawing is a structural representation of the present utility model.
Embodiment
The reality octopus lay eggs the hatching used device a cylinder mould body 2 is arranged, there is nettle 1 its top; The network interface diameter of cylinder mould body 2 is 20-30cm, and the middle part diameter is 50-60cm, and base diameter is 40-50cm; Cylinder mould body 2 is made of tulle 3 and support 4, and the aperture of net is 1-2cm.Adorn one and adopt egg apparatus 5 in cylinder mould body 2, its diameter is 20-30cm, and long is 30-50cm.
When using the utility model, in close octopus storage pond, holding pond, throw in earlier and adopt egg apparatus 5, should guarantee that every octopus has to adopt egg apparatus 5 more than 2.Waiting to produce octopus can hide and lay eggs in adopting egg apparatus 5 and protect the ovum hatching through do revealing stimulation.Open 2 mouthfuls of ends of cylinder mould body, the octopus that begins to lay eggs is together moved on in this device together with adopting egg apparatus 5, tension nettle 1.Support 4 is made of stainless steel strip, can keep support 4 to have high resiliency and toughness, and stainless steel strip is coated in the plastic tube in addition, makes support 4 not perishable in seawater.The aperture of net is 1-2cm, at the bottom of guaranteeing that the ovum string can not fall into the pond in net, only with the metabolic waste of true octopus, is discharged to as ight soil, the sucker membrane that comes off etc. and cultivates in the pond and cleaned out.Each cylinder mould body 2 is only placed the octopus of laying eggs.Then this device is the beads shape by polyethylene nettle 1 and is suspended on cultivation 1/3-2/3 water layer place, pond, the flowing water inflation is cultivated.Octopus can continue to lay eggs and protect ovum in cylinder mould body 2, makes ovum group normal development.
During concrete operations, 1. temporary 15 of adopted parents' bodies in holding pond, support temporarily density 1-2 only/m
3, water temperature 14-20 ℃, shading, inflation is changed water 1 time/day, and quantity of exchanged water is total 1/3 of water body of supporting temporarily; 2. throw something and feed live fish and shrimp and bivalve shellfish were thrown something and fed once in 2～3 hours, fewly threw diligent the throwing, the parent promotion gonad maturity that progressively heats up; 3. throw in and adopt egg apparatus 5 (Φ=20～30cm), length are 30-50cm, and throwing in density is that every octopus is more than 2; 4. the dried dew of octopus parent employing is hastened parturition after stimulation a period of time, move in the spawning pond shading, flowing water, inflation, seawater salinity 28-30; Above-mentioned parent successively has 9 female octopus to lay eggs; 5. with female octopus together with adopting egg apparatus 5 and the group of laying eggs moves into to isolate in this device and cultivates, avoid close octopus to cut one another's throat, 18～23 ℃ of water temperatures, inflation is hatched, seawater salinity 25～30; The average egg laying amount of true octopus is 150,000; 6. through hatching in 25-30 days, obtain about 1,000,000 of the membrane young, incubation rate is up to more than 70%.The young moved to cultivate in the pond, adopt artemia nauplii, the ocean shell-fish young is as the open-mouthed bait young of throwing something and feeding, and natural temperature is cultivated.
