The hemibarbus maculatus bleeker artificial reproduction method has the advantages that the growing and breeding characteristics of hemibarbus maculatus bleeker are sufficiently used, the overall breeding process is easy to operate, the breeding technology is outstanding, and the hemibarbus maculatus bleeker artificial reproduction method has the obvious economic, ecological and social benefits.
Description
Technical field
The present invention relates to technical field of aquaculture, particularly a kind of hemibarbus maculatus fish artificial fecundation method.
Background technology
Hemibarbus maculatus fish, has another name called large eye drum, fiber crops spears fish.Taxonomy belongs to Cyprinidae, fish sentence subfamily.Mainly be distributed in the rivers of the Yangtze river basin, lake, reservoir.This fishing gear has that the bodily form is graceful, feeding habits are mixed, strong adaptability, cultivation scope is wide, population yield is high, sell well in fine and tender taste, delicious flavour, market advantage.Existing market only can not meet its demand by the natural hemibarbus maculatus fish fished for, and holds at high price, propagates hemibarbus maculatus fish artificially and can obtain higher profit.Because natural resources destroy day by day, natural seeding, wild fry output can not meet cultivation demand, how to provide a kind of artificial propagation hemibarbus maculatus fish to obtain seed, has become scientific worker and the new concerned issue of numerous raisers.
Summary of the invention
For above-mentioned situation, the object of the invention is just to provide a kind of hemibarbus maculatus fish artificial fecundation method.
For achieving the above object, the technical solution used in the present invention is: it is characterized in that being made up of following steps:
1, parent fish rearing: select from cultivating through artificial-strengthening in river, lake, thus can natural propagation be carried out.Cultivating pond will near water source and spawning pond, and the depth of water is at 1.5-2 rice, and area is 1-3 mu.Breeding density is 150-200 kg/acre, puts the saline sook fish body 5-10 minute of front 0.3%-0.5% in a suitable place to breed.Throw something and feed pellet, every 7-10 days adds water once, adds the 15cm of Chi Shui at every turn.
2, the selection of parent: owing to being the parent taken pains to foster, parent's nutritional sufficiency, spawning rate is high.Select physique stalwartness, the anosis fish without wound is as parent population, and raun belly expands, and ovary profile is obvious, the seminal fluid of milter becomes milky thick, enters water and namely falls apart, and the pearl star of head adularescent, touches with harsh feeling with hand, raun is without pearl star, and hand is touched smooth, and the ratio of male and female is 1: 3-5.Female parent population body weight 0.4 kilogram/tail, male parent population body weight 0.3 kilogram/tail.
3, parent supports temporarily: the parent chosen is put into storage pond, holding pond and supports temporarily, and storage pond, holding pond is cement pit, and area is 100 square metres, and the depth of water 1.2 meters, has perfect culvert system, and steel structure heat-insulating sunshade has been built in the top in pond, and whole day gives micro-stimulation by running water in 24 hours.
4, artificial induced spawning: the morning 9:00-10:00, when water temperature reaches 24 DEG C, parent is placed in net cage and has reexamined one time, female, malely separately to support temporarily.2 pm carries out artificial induced spawning, and injected dose is raun LRH-A310 micro-g/kg+DOM10 mg/kg, and milter reduces by half.Injection is divided into double injection, 1/3 of first time injection accumulated dose, and 2/3 of second time injection accumulated dose, needle gage is 6-8 hour, and injection site is pectoral fin base portion.After 14 hours, check raun egg development situation every half an hour, until find that there is when laying eggs sign, pull female, hero out and carry out artificial insemination.Ovum clear water after insemination washes postprecipitation half an hour, then with graduated cylinder counting, puts into hatching pail hatching.
5, hatch: flower
ovum tool viscosity, select yellow mud cling to carry out unsticking.Put into hatching pail after unsticking to hatch, the flower of just hatching
ovum is transparent yellow, smooth, circle ovum.The flow velocity of hatching pail water is 3-5cm/s.Last four days from hatching to membrane, within 72 hours, all sprout.
6, seed rearing: fingerling pond is Tu Chi, area 1-3 mu, depth of water 1.0-1.5 rice, gravel substrate, draining is convenient, and have abundant water resources, water quality is pure and fresh; Intake-outlet is equipped with firmly to be prevented escaping grid.Put membrane 7 age in days fry in a suitable place to breed, density is 12-15 ten thousand tails/mu.Early stage throws something and feeds and filters through net thin,tough silk the egg yolk boiled, and changes pellet of throwing something and feeding into gradually.
Beneficial effect of the present invention: a kind of hemibarbus maculatus fish of the present invention artificial fecundation method, make full use of full hemibarbus maculatus sashimi (raw fish) length, multiplication characteristic, whole reproductive process is simple to operate, and propagation technique is given prominence to, convenient management, high financial profit.
