Description
Technical field
The present invention relates to technical field of aquaculture, particularly to one circle kiss silver xenocypris artificial fecundation method.
Background technology
Circle kiss silver xenocypris is a kind of middle-size and small-size silver xenocypris section Fish, the ingest organic debris in water body and epiphytic algae.Circle kiss silver xenocypris strong adaptability, growth is fast, easily fishes for.It is high containing meat amount, and fine and tender taste is delicious, nutritious, favored by consumers.But in recent years, the circle kiss wild seed resource of silver xenocypris is seriously damaged, and causes that supply falls short of demand in market, and price constantly raises up.A kind of artificial propagation how is provided to obtain circle kiss silver xenocypris seed, it has also become the new problem that everybody pays close attention to.
Summary of the invention
For above-mentioned situation, the object of the invention is just to provide a kind of circle kiss silver xenocypris artificial fecundation method.
For achieving the above object, the technical solution used in the present invention is: circle kiss silver xenocypris parent fish selection, parent fish rearing, Sex judging, artificial induced spawning, artificial incubation and fry rearing.It is characterized in that being made up of following steps:
1. parent fish selects: winter or early spring in next year, selects body constitution stalwartness, anosis without wound, 2 ages in winter.
2. parent fish rearing: fermentation muck is discharged in parent fish rearing pond after the beginning of spring, makes water transparence be maintained between 25-30 centimetre, and every day, every tail fed bean milk, furfur etc. 10-15 gram.Within every 2 weeks, wash by water 1 time, keep water quality fertile, tender, refreshing.Draw in the net to take exercise 2-3 time in spring, autumn.
3. Sex judging: having white pearl star to occur on milter head, the gill cover, pectoral fin and scale, body surface is more coarse than raun, light pressure abdominal part can extrude milky seminal fluid.Raun abdominal part expands, and ovary profile is obvious, and pressure sensitivity is soft, it is also possible to taking ovum inspection with digging egg apparatus, ovum grain size is uniform, it is easy to separately.
4. artificial induced spawning: annual late April is to, at the beginning of 5 months, when water temperature stability is at 18 DEG C, carrying out artificial induced spawning.Hasten parturition suitable water temperature 18 DEG C-27 DEG C, optimum water temperature 20 DEG C-25 DEG C.Adopting a pectoral fin injection, female parent fish dosage Medulla Cyprinus carpio pendant 2-3 mg/kg, milter reduces by half.After injection, parent fish is put in spawning pond in the ratio of female, male 1: 2.5 so that it is natural spawning fertilization.Under 18 DEG C of-20 DEG C of water temperature conditions, within 10-12 hour, lay eggs；Water temperature 21 DEG C-24 DEG C, 9 hours are laid eggs；Water temperature 25 DEG C-27 DEG C, can lay eggs for 6-8 hour.Laying eggs when parent fish oestruses, every cubic metre of water body sprinkles 1 kilogram of unsticking of yellow mud pulp-water in time.Add new water after 20-30 minute and collect germ cell.
5. artificial incubation: the germ cell after unsticking moves into Lotic hatching in circular hatching channal.Every cubic metre of water body puts germ cell 80-100 ten thousand, cuts off the water dipping bath 8-10 minute with 10g malachite green solution, prevention of water mildew.Open inlet valve, carry out Lotic hatching.The water velocity of hatching flowing water is to see that germ cell grain stirs up and down with current.Spawning water must filter through 80-100 order gauze, in case harmful organisms and other impurity enter.Under the water temperature condition of 22 DEG C～25 DEG C, germ cell can be emerged by demoulding through 40 hours.The postlarva of firm demoulding, less than family fry, delicate, without Burden-Swimming Ability of KM, can only be floating up and down with current.When postlarva fish glue occurs and can put down trip, reduce flow velocity, to reduce postlarva physical consumption.
6. fry rearing: demoulding is after 3 days～4 days, actively during initial feeding, under fry, pond is cultivated, the pool under " rich water ".Put " spray " 25-30 ten thousand tail in a suitable place to breed for every mu.When fry body is up to 3cm, should divide rare to 8-10 ten thousand tails/mu.During the firm initial feeding of fry, every 50,000 tail fries are thrown something and fed 1 ripe egg yolk, with the lower pool of being satiated with food.Starting, from the 2nd day, bean milk of throwing something and feeding, every day wears into bean milk with 3-4.5kg/ mu Semen Glycines, throws something and feeds 2-3 time.Along with the increase with food ration of growing up that fry is individual, should suitably increase the throwing amount of raising.When fry body is up to 3cm, artifical compound feed of can throwing something and feeding.
Preferably, described a kind of circle kiss silver xenocypris artificial fecundation method, it is characterised in that the parent fish body weight in described step 1 is 600-750 gram.
Preferably, described a kind of circle kiss silver xenocypris artificial fecundation method, it is characterised in that the breeding density in described step 2 is 3000-3500 tail/mu.
Preferably, described a kind of circle kiss silver xenocypris artificial fecundation method, it is characterised in that the oxytocic drug in described step 4 is Medulla Cyprinus carpio pendant.
Preferably, described a kind of circle kiss silver xenocypris artificial fecundation method, it is characterised in that the cultivation pond in described step 6 is Tu Chi, area 3-5 mu.
Beneficial effects of the present invention: one of the present invention circle kisses silver xenocypris artificial fecundation method, fully holds the circle kiss growth of silver xenocypris, growth and reproductive characteristic, and whole reproductive process is simple to operate, applicable, and reproduction technique is novel, convenient management, high financial profit.
