Abstract

The characteristic lies in that the healthy grass goldfish with sexual maturity is selected as female parent and the healthy coloured carp with sexual maturity is selected as male parent, and the their colours are not limitted. In the breeding season, the artificial hastening parturition is conducted to the female parent and the artificial insemination is conducted by using the male parent's semen. The incubation is conducted in the running water. When the fry grow lumbar spot, they are cultured in the pond. After the fry grow to 5 cm, they are tamed and cultured with pellet food. The bodies of filial generation are multikinds in colour, some are green, some are yellow, golden, silver, red spot etc. The advantages are good for edibleness and viewing and admiring.

Description

A kind of method of producing flower crucian carp

The invention belongs to a kind of method that obtains the crucian new varieties by artificial hybridization.

Crucian meat flavour deliciousness, nutritious, be the aquatic products that people generally like.But the output of crucian is very limited in natural, ecological, fish for the comparison difficulty simultaneously, therefore, fast growth good with people's proximities cultivated in the artificial hybridization successively of big Min Tun fishing ground, Xinmin City, Liaoning Province, body weight can reach 400 grams above " stupid crucian ", " tame crucian ", and it is very welcome to put goods on the market; Various places were also cultivated the improved seeds of crucians such as Pengzhe fish, hybridized prussian carp, Hunan crucian carp, emerging Huaihe River crucian carp, loose Pu crucian carp successively in recent years.Though these above-mentioned crucian new varieties have significant advantage, body colour mostly is the body colour of single silvery white, traditional crucian such as greyish white, yellowish-white, therefore only has edibility, and does not have ornamental value.

The purpose of this invention is to provide a kind of method of producing multiple color, the beautiful crucian of color and luster, have edible and view and admire dual value, and raise and train easily, economize feed, the bodily form is generous, output is high.

Method of the present invention is to select for use grass goldfish to make female parent, carries out artificial hybridization and acclimatization culture with bright and beautiful carp as male parent.Learn from the aquatic products theory: as the grass goldfish of female parent by the wild carp derivation, its external form and wild carp are basic identical, over the past thousands of years, wild carp is owing to be subjected to the influence of natural environment, the generation that has variation, pass through people's selection and special raising again, melanocyte in its scale fades away, therefore erythrocyte increases gradually, makes body colour transfer redness, reddish yellow to by silver gray, also has patterns such as a spot of red white, red and black.Though grass goldfish is bright-colored, see that the people does not fear, good domestication, fine figure, poor growth, individual less, only be suitable for viewing and admiring, edibility is very low.In order to obtain having the crucian new varieties of certain pattern, fast growth, the present invention adopts bright and beautiful carp to make male parent.The brocade carp originates in China, after reach Japan, Germany and all over the world, full squama brocade carp is arranged, squama brocade carp and do not have the bright and beautiful carp of squama looses, the growth rate of brocade carp is more faster than grass goldfish, and gay colours is arranged, magnificent speckle, docile personality is the desirable male parent of cultivating flower crucian carp.Production method of the present invention is as follows: at first gather healthy anosis, sexually matured grass goldfish and do female parent (♀), pattern is not limit; Gather healthy bright and beautiful carp anosis, property one-tenth heat again and do male parent (♂), pattern is not limit; In mating season female parent is carried out artificial induced spawning, carry out artificial insemination with male parent testicular fluid, carry out the hatching of unsticking flowing water, treat that juvenile fish grows waist and puts the pool at present, early stage, fry carried out the granular bait for fish acclimatization culture after surpassing 5 centimetres based on rich water.

The present invention has the following advantages:

1, figure and body colour have extremely strong novelty.The one, the anti-ancestral of figure of hybridization first filial generation fish is to the form of crucian, the 2nd, the body surface color presents variation, has patterns such as green, yellow, golden yellow, silver color, erythema, and what have is the squama type that looses, this is the phenomenon that was not had in crucian colony since the dawn of human civilization, has therefore formed the food fish with sight.

2, Za Jiao filial generation fish sees that the people does not fear, and proximities is good especially, can line up to beg for food to the people, and it is responsive that bait is fallen into water, and is suitable for that artificial intensive is large quantities of raises and train.

3, Za Jiao filial generation fish build, the maternal grass goldfish (crucian type) of complete bar, and the approximate bright and beautiful carp of growth rate, year fry can be grown to more than 200 grams, can reach in 1 year more than 500 grams, and fine and tender taste, cellulosic are few, and vitreum increases, and palatability is extremely strong, pattern is pleasant, a fest to the eye, very easily go on market, lay out dining table.

4, because father and mother Dai Shi is derived by artificial feeding under various environment forms, the basis is fine, therefore the filial generation fish of hybridization has formed that physique is strong, adaptability strong, anoxia enduring, can make full use of all the animal and plant food resources in the water, save bait, feeding cost is low, and its economic benefit is very considerable.

Provide embodiment below.

At first gather healthy anosis, sexually matured grass goldfish and do female parent (♀), pattern is not limit, and a year order is preferably in the 2-6 order, body weight more than 100 grams for well.

Gather healthy bright and beautiful carp anosis, property one-tenth heat again and do male parent (♂), pattern is not limit, and a year order is preferably the 3-7 order, and body weight 500 grams are above for well.

Joint is given the raun oxytocin injection in breeding committee, and milter reduces by half, and ripe good milter can not injected.

Impel raun that ovum is produced in container, use test-tube method (wet method, dry method all can) to make smart ovum branch fill mixing then, slightly quiet 2-3 minute again with the dense magma unsticking of fertilized egg with talcum powder or mud, the flowing water hatching or not unsticking fertilized egg evenly is bonded at brown sheet, or hatch on the bolting silk sheet.Water temperature is controlled between 16-26 ℃, grows waist point through 5-7 days juvenile fish and can reach the pool at present, and can in right amount feed a little soya-bean milk based on rich water early stage, adopts the granular bait for fish acclimatization culture until forming adult fish after fry surpasses 5 centimetres.
