A method for laying eggs and hatching octopuses and the device used, the method is ① temporarily raising the parent body; ② promoting the maturation of the parental gonad; ③ putting in an ovipositor; ④ inducing labor; Carry out aerated hatching; ⑥Collect the octopus seedlings hatched out of the film and cultivate them in the cultivation pond. The egg picker is a PVC pipe with a diameter of 20-30cm; the bottom diameter of the device used for hatching is 40-50cm, and the mesh size wrapped by the cage body is 1-2cm. It is beneficial to the development and hatching of brood-protecting eggs and fertilized eggs, avoiding other octopus stealing fertilized eggs and parental octopuses fighting for habitat, making full use of the cultivation water body, and increasing the cultivation density and hatching rate of larvae.
Description
Technical field
The present invention relates to the method for a kind of aquaculture field ocean siphonopods seed hatching, relate in particular to a kind of octopus the lay eggs method of hatching and used device.
Background technology
Octopus belongs to Mollusca, Cephalopoda, Octopodida, octopus section, and wherein true octopus is the extensive species that distribute in the world, 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.Octopus class fertilized egg close octopus in hatching process has the ovum of protecting characteristic, and habitat and hatching place by fight protection oneself each other prevent from by other octopus fertilized egg to be eaten up.Under the artificial environment, obtaining a large amount of growth health and synchronous seed is the important step of artificial breeding success.China has not yet to see the relevant report that relevant octopus class is laid eggs and hatched.
Summary of the invention
The purpose of this invention is to provide a kind of octopus lay eggs the hatching method and used device, it can satisfy the demand of prior art.
The method that a kind of octopus is laid eggs and hatched is characterized in that 1. carrying out close octopus and supports temporarily in holding pond; 2. close octopus gonad maturity accelerating; 3. throw in and adopt egg apparatus; 4. hasten parturition; 5. inflation hatching; 6. collecting the octopus class seedling of incubation of membrane cultivates in cultivating the pond.
Implement the above-mentioned octopus used device of hatching m of laying eggs, it is characterized in that having a cylinder mould body, 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; In addition, also be equipped with one and adopt egg apparatus.
The invention has the advantages that:
1. support temporarily and accelerating at cement pit by octopus class parent, particularly fully supply with and heat up, make gonad development good by high-quality bait;
2. adopt and suitable to adopt egg apparatus to form the artificial spawning field be the important step that true octopus is laid eggs, the pvc pipe of diameter and moderate length not only satisfies octopus lays eggs and protects ovum, and is convenient to production operation, and particularly ovum group easily collecting and embryonic development are easily observed;
3. the device of hatching of laying eggs can effectively be isolated from each other parent, makes it protect ovum under security context, avoids mutually fight and influences the growth of ovum, can prevent that also other octopus from eating its fertilized egg steathily.Adopt this device can under artificial environment, obtain a large amount of grow healthy and synchronous seeds, improve incubation rate greatly.
4. in addition, this device is the beads shape is suspended on lower floor in the pond, can improve the water body utilization ratio, increase parent density, their metabolic waste is fallen at the bottom of the pond, is easy to cleaning, guarantees the water body cleaning.For next step seed rearing has been laid solid foundation.

Accompanying drawing is an apparatus structure schematic diagram of the present invention.
1. nettles among the figure; 2. cylinder mould body; 3. tulle; 4. support
Embodiment
Below in conjunction with drawings and Examples the present invention is described in further detail.
When implementing method of the present invention, employing lay eggs hatching apparatus as shown in the figure, it has a cylinder mould body 2, there is nettle 1 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; In addition, also be equipped with one and adopt egg apparatus.
The density 1-2 of temporary adopted parents' octopus/m
3, water temperature 10-23 ℃, salinity 20-35.Adopt the accelerating that progressively heats up, the live fish and shrimp of throwing something and feeding.The egg apparatus of throwing in of adopting is diameter 20-30cm, and the pvc pipe of long 30-50cm guarantees that every octopus has the egg apparatus of adopting more than 2.Waiting to produce octopus can hide and lay eggs in adopting egg apparatus 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 the hatching apparatus together with adopting egg apparatus, tension nettle 1.Support 4 is to be made of stainless steel strip, keeps 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 1-2cm of net guarantees that the ovum string can not fall in net at the bottom of the pond, only with the metabolic waste of 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.
Specific operation process is: 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 then and adopt egg apparatus, for pvc pipe (Φ=20～30cm), length are 30-50cm, throw in density and be every octopus 4. the octopus parent is adopted more than 2 do that revealing hastens parturition and stimulate a period of time after, 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. female octopus is cultivated together with isolating in the device of adopting egg apparatus and group's immigration hatching usefulness of laying eggs, avoided 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.
