Abstract
At present, the total artificial breeding technology is generally used for breeding Carassius aurutus gibelio in our country, which has the main following defects due to adopting an artificial insemination method: influenced parent survival rate, low fertility rate, hatchability and increased offspring seed cost. In the semi-artificial breeding technology for Carassius aurutus gibelio in the invention, the artificial insemination in the complete artificial breeding process is changed into natural insemination, namely, a natural breeding environment for the Carassius aurutus gibelio is simulated in a pond so as to enable the male and female parents to perform copulation and breeding. The invention has the following advantages: the pond is utilized to create the natural breeding environment for the Carassius aurutus gibelio so as to improve the fertility rate which can reach above 95% generally; and natural copulation between the female and male parents is finished in the pond, thus avoiding parents from being injured, improving the parent survival rate, saving a great amount of manpower and material resources and effectively enhancing the breeding efficiency. Therefore, the semi-artificial breeding technology for the Carassius aurutus gibelio in the invention can solve the problem of breeding the Carassius aurutus gibelio in a scale.
Description
Technical field
This invention belongs to technical field of aquaculture, specifically is exactly a kind of method of utilizing pond large-scale artificial breeding hybridized prussian carp seed.
Background technology
Hybridized prussian carp utilizes and carries out gynogenesis after triploid upright pond crucian carp (female parent) and diplontic carp (male parent) artificial hybridization and breed.Characteristics such as growth is fast, individual greatly because this fishing gear has, strong stress resistance demonstrate the good and economic shape in breeding production, supply falls short of demand for its seed.At present, the whole artificial propagation technology is all adopted in the artificial propagation of China's hybridized prussian carp.This whole artificial propagation technology mainly contains following defective owing to adopt artificial insemination method: the one, and when artificial insemination, be easy to cause the parent injured, influence parent survival rate; The 2nd, artificial insemination needs a large amount of man power and materials, and consuming time, has influenced the scale reproductive efficiency of hybridized prussian carp, but also has increased the seed cost.The 3rd, during artificial insemination, easily immature essence, ovum are also extruded, cause fertilization rate low, influence incubation rate.
Summary of the invention
The parent is easily injured in the present hybridized prussian carp whole artificial propagation process, fertilization rate is low and inefficient present situation in order to solve, the present invention is improved to the nature insemination with the artificial insemination in the whole artificial propagation link, promptly at pond inner imitation hybridized prussian carp natural propagation environment, make female, male parent self-copulation breeding in the pond, effectively improve reproductive efficiency, fertilization rate and the incubation rate of hybridized prussian carp, also saved the man power and material.
The technical scheme that this invention provides is that a kind of semi-artificial breeding technology for Carassius aurutus gibelio may further comprise the steps:
(1) preparation of breeding pond and hatchery.Breeding pond and the general area 2000m in hatchery
2～3335m
2, depth of water 1.8m.Breeding pond and hatchery were used quicklime 150g/m in preceding 10～15 days putting in a suitable place to breed
2～200g/m
2Sterilization.
(2) parent selects.Annual March, select 2 age hybridized prussian carp as female parent, specification is that the bodily form is normal more than the 500 gram/tails, body colour is silver grey; Select carp as male parent, specification is 500～800 gram/tails.The male and female ratio is 1.5: 1.The parent who chooses is put in reinforced cultivating in the breeding pond.
(3) make the fish nest: the parent hastens parturition the last week, and selecting the willow root of the soft pogoniasis of matter is the fish nest, after the willow root boils, sterilizes, dries, is tied to the top of bamboo pole, and bamboo pole inserts in around the breeding pond, and bamboo pole spacing 3～5m makes the fish nest top Chi Shuizhong that just submerges.
(4) parent hastens parturition.Generally at the beginning of 5 months by the end of April, maternal pond crucian carp belly softness, the male parent carp gently presses belly adularescent seminal fluid to flow out, and gonad development maturation be described.As long as breed the pond water temperature and reach more than 18 ℃ this moment, select fine day that the parent is hastened parturition.Every kg raun body weight injection carp or crucian carp hypophysis 4～6mg, or inject fish and use luteotropin releasing hormone d-ala analog (LRH-A) 20～50ug, milter reduces by half.
(5) natural spawning.After hastening parturition, parent population puts in a suitable place to breed in the breeding pond.At this moment, constantly the new water of filling in the breeding pond stimulates parent's hormone secretion.In morning next day, female, male parent can match by nature, oestruses and chases, and essence, ovum are originated on the fish nest, finishes the insemination process.When treating on each fish nest to adhere to fertilized egg 3～50,000, in time extract the bamboo pole that has the fish nest, move to the hatchery hatching.
(6) fry hatching.Fish nest two ends are tied up to respectively on two bamboo poles, make the fish nest be fixed on the water surface below 10 centimetres.Simultaneously, the peaceful 50mg/L of probiotics benefit water that splashes in the pond.Behind the fry membrane, pond planted agent's organic fertilizer is cultivated natural feed, and the soya-bean milk of splashing every day.
The semi-artificial breeding technology for Carassius aurutus gibelio of this invention changes the artificial insemination in the whole artificial propagation link into the nature insemination exactly, promptly at pond inner imitation hybridized prussian carp natural propagation environment, makes female, male parent self-copulation breeding in the pond.This invention has the following advantages: utilize the pond to build the natural propagation environment of hybridized prussian carp, impel fertilization rate to improve, generally can reach more than 95%; Female, male parent natural mating in the pond can not cause the parent injured, have improved parent survival rate; Female, male parent natural mating in the pond can be saved a large amount of man power and materials, effectively improve reproductive efficiency.Thereby semi-artificial breeding technology for Carassius aurutus gibelio has solved the difficult problem of hybridized prussian carp seed propagation in scale.
