Description
Technical field
The present invention relates to culture of ornamental fish technical field more particularly to a kind of mating systems of dragon eye goldfishes.
Background technology
Dragon eye goldfishes are one kind of fish, usual bodily form tubbiness, and head is flat and wide, and squama is round and big, relatively suitable for as ornamental
Fingerling.Dragon eye goldfishes shape is similar to language, and not existing together protrudes from for eyeball outside eye socket.Regard since ancient times dragon species as goldfish just
Ancestor.Existing dragon eye goldfishes mating system due to parent population screening, cultivate not science, oviposition, hatching shortage standard specification, make
At rate of fertilization, hatching rate and the low problem of survival rate of fish fry, dragon eye goldfishes is made to be difficult to realize breed on a large scale.
Invention content
Present invention seek to address that the deficiencies in the prior art, and a kind of mating system of dragon eye goldfishes is provided.
The present invention to achieve the above object, using following technical scheme：
A kind of mating system of dragon eye goldfishes, is as follows：
(1) parent population breeding environment management：
Select area for 10-30m2, the aquaculture pond of pond depth 30-80cm, aquaculture pond is internally provided with independent culvert system,
Discharge outlet is located in pond, and aquaculture pond bottom slope is 5-10 ‰, is put in a suitable place to breed before fingerling 3 days, with acid soak aquaculture pond, impregnates 22-
Acid solution is released after 24 hours, with 2-3 times in clear water flushing tank；
(2) screening and cultivation of parent population：
Parent population selects the milter of the raun and 1 age in 2-4 ages, by 2-3: 1 combo of sex ration, every square metre of dispensing 3-5 group, parent
Fish put in a suitable place to breed after 2-3 days after start to feed feed, select fresh and alive macrozooplankton or crude protein content puffing more than 32%
Feed is eaten as fish, and minerals vitamin is added in fish food, and feeding volume adjusts in time according to season, and summer and autumn day, feeding rate was in 2-
4%, spring day feeding rate is 2-3%, launches a fish food respectively in 8 points of every morning and at 4 points in afternoon, the weight of each feeding is extremely
It is 0.01 times of fingerling weight less, water was changed every 5-7 days 1 time；
(3) antenatal preparation and oviposition：
Spawning pond is 1-2m2Rectangular pond, inner wall smooth and color is dark, spawning pond are disappeared with 0.5% sodium bicarbonate cleaning
After poison, the fresh water of 3 mesh filter screen filtrations is injected, puts the brown piece or water plant that methylene blue sterilized, parent population to be produced is few
Amount feeds macrozooplankton or expanded pellet diet, and spawning pond water temperature is set as 16-17 DEG C, and micro- stimulation by running water, parent population stops eating automatically
When, night increased water flow when oviposition stimulates heat, morning next day to start to lay eggs, when parent population reaches heat peak, manually squeeze ovum,
Essence is squeezed, after being stirred 2-5 minutes with feather, clear water rinses 2 times and completes insemination, makees fish nest with the plastic tub of diameter 30-35cm, is fertilized
Ovum is uniformly sprinkled on fish nest, and every fish nest adopts 2000-3000, ovum, and every group of parent population adopts ovum 2-4 batches altogether in two weeks, lays eggs every time
Parent population is put back into former parent fish pond afterwards, adopts 2000-3000, ovum every time；
(4) hatching of fertilized eggs and the cultivation of fry：
Fish nest with fertilized eggs is put into hatchery, keeps, into water 20-30cm, putting 30, fish nest per acre, hatches water
Temperature is at 18-22 DEG C, and dissolved oxygen takes out fish nest after a week in 5.0mg/L or more, fry birth, and fry feeds yolk after being born 3 days
Water, every ten thousand tail feed 1-2 soft-boiled eggs Huang, filtered cladocera are fed after 5-10 days and coordinates yolk and soya-bean milk, after 20 days
Feed expanded pellet diet；
(5) screening of fry：
Primary election is carried out when fry overall length is grown to 2-3cm, the inferior fish of tail exception, physical abnormality is screened out, when fry is complete
It is long to 4-5cm when, carry out final election, screen out that tail is asymmetric, the tail heart is askew, build shade deviation fish, once drawn before final election
Net is taken exercise, and carries out preferably, selecting posture grace, bright in colour, character defect individual outstanding to fish when fish grows up to marketable fish.
Preferably, the phosphoric acid solution that the acid solution described in step (1) is a concentration of 0.25%.
Preferably, water 15-20% is changed when changing water in step (2) every time, overwintering period and breeding do not change water or two in first 30 days
Change a water week.
Preferably, in step (3) plastic tub using first 2 days with need concentration 20mg/L Eusols impregnate 1 hour.
Preferably, in step (5) preferably before need carry out twice seine take exercise.
The beneficial effects of the invention are as follows：The management of dragon eye goldfishes mating system breeding environment of the present invention and parent population
Screening mode it is scientific and reasonable, using fish nest hatch fish-egg, convenient for observation fish-egg developmental state, breed ahead of time, improve fish-egg at
Motility rate is easy to control fish-egg developmental temperature during hatching, water consumption is few, is easy to distinguish the quality of fertilized eggs, greatly improves goldfish
Hatching rate.
