Abstract
The present invention is the breeding process of hybrid scallop. The breeding process with comb-hole scallop and comb shell scallop as parents includes culturing comb shell scallop in natural sea water at 8-12 deg.c, culturing comb-hole scallop in a hatching pond at temperature increased from 8-10 deg.c to 12-18 deg.c, collecting egg or semen of comb shell scallop in natural sea water, laying egg or semen of comb shell scallop into the hatching pond for fecundation and hatching at 10-18 deg.c. The said process can breed antiviral hybrid scallop variety with high quality.
Description
One, technical field:
The invention belongs to marine shellfish Hybrid breeding method technical field, especially relate to the breeding method of a kind of chlamys farreri, Patinopecten yessoensis intermolecular hybrid kind.
Two, background technology:
Scallop kind in China's mariculture mainly is a chlamys farreri at present, chlamys farreri has been cultured lethality since 97 years very high, caused very big loss for the breed unit, the cause of death of chlamys farreri is to culture the biological capacity that quantity has surpassed the ocean carrier by analysis, formed virus infections, simultaneously because nature seawater temperature rising in recent years, cause chlamys farreri virus to show effect in advance, thereby caused the large tracts of land death of chlamys farreri, according in the past few years to the breed situation analysis of other kind scallops, chlamys farreri virus only limits to the chlamys farreri population, little to other kind scallop influences, Patinopecten yessoensis mainly moves in Japanese marine site, and is narrow in China life marine site, only limits to the north of Bohai zone, other the zone since summer ocean temperature higher, Patinopecten yessoensis can't be spent the summer, but its life habit, biological property and chlamys farreri are approaching, for the hybridization of two kinds provides scientific basis.
Three, summary of the invention:
The objective of the invention is to improve the deficiency of prior art and a kind of breeding method that utilizes parent chlamys farreri, Patinopecten yessoensis to cultivate the Hybrid scallop that makes new advances be provided, cultivate have viral infection resisting, survival rate of seedlings height, growth preference temperature scope are wide, strong adhesion, meat cubelets are big, output is high scallop hybrid.
The object of the present invention is achieved like this, and a kind of method for cultivating scallop hybrids is characterized in that this method may further comprise the steps:
A, when the nature seawater temperature is 8-10 ℃, it is that cultivate 8-10 ℃ hatchery that the parent chlamys farreri of getting into live fresh body and sexual gland physical maturity is put into initial temperature, the sex character of parent chlamys farreri must be single in each hatchery, can not male and female cultivate in same hatchery;
B, heated up gradually in the hatchery, make the hatchery temperature reach 12-18 ℃, in temperature-rise period, the effective accumulated temperature of hatchery will reach 1000-1200 ℃;
Parent chlamys farreri in c, the observation hatchery when ovulation or row's essence take place, should take to cultivate the parent Patinopecten yessoensis in 8-10 ℃ of nature seawater immediately, and the parent Patinopecten yessoensis is necessary for into live fresh body and sexual gland physical maturity;
D, the parent Patinopecten yessoensis is dried in the shade, make its ovulation or row smart, get its ovum or sperm and put in the hatchery, make essence, the feritilization of ovum of different parent kinds, become fertilized egg, should avoid when getting sperm or ovum polluting;
Temperature is reached maturity fertilized egg naturally and is got final product at 10-18 ℃ in e, the maintenance hatchery.
Ovulation of parent chlamys farreri or smart time difference of row should be in 3 hours in row's essence of parent Patinopecten yessoensis or ovulation and the hatchery.
The ratio that smart ovum is thrown in the hatchery is 5-6: 1.
The present invention utilizes chlamys farreri, the Patinopecten yessoensis life habit, the characteristics that biological property is approaching, in the season of 8-10 ℃ of seawater natural temperature, artificial culture parent chlamys farreri is laid eggs it or is arranged essence, avoid artificial stimulation to lay eggs ahead of time or arrange smart, to obtain fully ripe ovum or sperm, the parent chlamys farreri accompanies the foster effective accumulated temperature will be at 1000-1200 ℃ in the hatchery, for guaranteeing parent scallop essence, the quality of ovum, the parent chlamys farreri, row's essence of parent Patinopecten yessoensis, the ovulation period difference will be controlled in 3 hours, should be fertilized as early as possible after the smart ovum output, otherwise can influence the fertilization of ovum, be difficult to form fertilized egg, in the process of fertilization, should guarantee the ovulation of two kinds of parents as far as possible, the smart time difference of row is short more good more, after fertilized egg produces, the temperature of hatchery will remain between 10-18 ℃, is beneficial to development of fertilized ova.
Four, specific embodiments:
Describe breeding method of the present invention in detail below by specific embodiment.
Embodiment, a kind of method for cultivating scallop hybrids, be chlamys farreri and the Patinopecten yessoensis that parent adopts fresh and alive and sexual gland physical maturity, the biological property and the life habit of these two kind scallops are approaching, for the hybridization between them successfully provides scientific basis, under the natural conditions when the nature seawater temperature is 8-10 ℃, the parent chlamys farreri is put into the initial temperature hatchery identical with the nature seawater temperature, the sex character that will guarantee parent in each hatchery is single, can not male and female raise together with, improve the hatchery temperature gradually, make the temperature of hatchery reach 12-18 ℃, in temperature-rise period in order to guarantee the chlamys farreri physical maturity, discharge ripe ovum or sperm, in temperature-rise period, the effective accumulated temperature of hatchery will reach 1000-1200 ℃, to examine parent chlamys farreri in the hatchery between temperature raising period, as ovulation or row are taken place when smart, should take to cultivate the parent Patinopecten yessoensis in 8-10 ℃ of nature seawater immediately, the parent Patinopecten yessoensis is necessary for into live fresh body and sexual gland physical maturity, the parent Patinopecten yessoensis is dried in the shade, make its ovulation or row smart, getting its ovum or sperm puts in the hatchery, be to be the ovulation of parent chlamys farreri in the hatchery, then put into the sperm of parent Patinopecten yessoensis, be that parent chlamys farreri row is smart in the hatchery, then put into the ovum of parent Patinopecten yessoensis, make the essence of different parent kinds, the feritilization of ovum, become fertilized egg, when getting sperm or ovum, should avoid polluting, to guarantee the quality of sperm or ovum, ovulation of parent chlamys farreri or smart time difference of row should be in 3 hours in row's essence of parent Patinopecten yessoensis or ovulation and the hatchery, the smart time difference of the ovulation of two parent kinds or row is short more good more, can improve survival rate like this, smart ovum ratio in the hatchery will remain on 5-6 simultaneously: 1, temperature is reached maturity fertilized egg naturally and is got final product at 10-18 ℃ in the maintenance hatchery.
Use the inventive method to cultivate the scallop hybrid kind, the success rate height of scallop hybridization, development of fertilized ova is better, survival rate of seedlings is higher than same kind, and the scallop that develops into of hybridization has that growth preference temperature scope is wide, strong adhesion, meat cubelets are big, output is high, avoided the characteristics of virus infections, to the production of mariculture scallop with develop significantly, and can solve the predicament of present mariculture.
