Abstract
The invention provides a new-variety reproductive regulation breeding method of lateolabrax japonicus and belongs to the field of fish breeding. Regulation targets of the method comprise a southern group and a northern group respectively; the regulation method includes illumination regulation, temperature regulation, salinity regulation and nutrient regulation; and a special incubation device is used when fertilized eggs are incubated. By regulating southern parent fish through gradually prolonging illumination time, stimulating temperature change, stimulating salinity change and the like, the development of sexual glands of the southern parent fish is facilitated, so that sexual maturity time of the southern parent fish is brought forward to October to December from November to January; and meanwhile, the illumination on northern parent fish is reduced and the northern parent fish is cultured at a low temperature, so that the development of the sexual glands of the northern parent fish is delayed, and the sexual maturity time of the northern parent fish is delayed to October to December from September to November. Therefore, the development of the sexual glands of the southern parent fish and the development of sexual glands of the southern parent fish is synchronized, and ovulation and sperm production are synchronized.
Description
Technical field
The invention belongs to fish breeding field, relate to a kind of flower perch new lines genital regulating breeding method particularly.
Background technology
Calico bass cultivation starts from the seventies, starts only to carry out in minority area bay, pond and to grow flower perch.Enter the eighties, south China mariculture is rapid, and perch is subject to green grass or young crops as net cage and pond culture kind and narrows.Have continuous ascendant trend in the cultivation status of China perch in recent years, the perch coastal expansion in the whole nation is supported in net cage and pond.Perch artificial breeding is studied, and has now entered the yielding ability stage.Parent population has two sources, and one is that wild maturation individuality is caught in sea; Two is excellent for selecting in cultured population.It is indefinite that parent population genetic background source is caught in sea, and growth traits is unknown.Cultured population Genetic variability is little, long-term breeding, and characters of progenies is degenerated.In order to supplementary parent, expand heredity, the perch of Different population can be selected to hybridize.But be September-November in the north flower perch egg-laying period, south is November-January.Although prior art also has by regulating temperature, illumination or hormone to carry out genital regulating, but parent population produces essence (ovum) amount less, incubation rate and emergence rate motility rate low, although illustrate that the parent population after regulation and control can reach sexual maturity, carry out laying eggs ejaculation, but gonad development is bad thus cause the of low quality of ovum or sperm.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of flower perch new lines genital regulating breeding method, the present invention is from the cultivation temperature of perch parent population, illumination, the factor such as nutrition and salinity, genital regulating is carried out to the perch of two geographical populations, promote gonad development or postpone gonad development, thus making the ground of two geographical populations
Parent population reaches synchronism maturation, and gonad development is good, and incubation rate and the survival rate of prelarva are high.
The present invention is achieved by the following technical solution:
A kind of flower perch new lines genital regulating breeding method, regulation and control object is respectively the Southern populations of colored perch and northern colony, regulate and control method comprises illumination regulation and control, temperature adjusting, salinity regulation and control and nutrition regulation, and use special hatching apparatus when incubating oosperm, concrete regulate and control method is:
Described illumination regulation and control: start to increase light application time gradually every day from the natural lighting time to Southern populations in June, increased by 1 hour every 7 days, be increased to illumination every day gradually 18 hours, then remain unchanged;
To northern colony, from June, the light application time reducing 1 hour every day from the natural lighting time until every day light application time 7 hours, then remain unchanged, until parent population gonadal maturation;
Described temperature adjusting: in 6-8 month, the temperature of cultivation of southern parent population is warming up to 30 DEG C gradually from natural temperature, within every 7 days, raises 1 DEG C, maintains 3 days, and then be cooled to 23 DEG C gradually, after this maintain 30; Control at 17-18 DEG C to northern parent fish rearing temperature, after gonadal maturation, be warming up to 23 DEG C gradually again;
Described salinity regulation and control: experiencing a salinity altercation to southern parent population in cultivating process stimulates, salinity altercation amplitude is 5 degree, decline and ascensional range are every day 1 degree, then maintain original cultivation salinity, salinity altercation and variations in temperature midfeather more than 3 days; Salinity nature breeding water salinity in the whole cultivating process of north parent population;
Described nutrition regulation, carries out mixing and throws something and feeds in the parent fish rearing process of Liang Ge colony, and namely throw something and feed in manufactured feed and wild fishes interval, to ensure comprehensive nutrition, promotes gonad development;
Described special hatching apparatus it comprise base, staving, spilling water parts and top cover, base has a groove, smooth glass ball is covered with in groove, the cover plate that one has permeable hole is stamped above ball, cover plate is fixed on base, base side wall has an inlet opening, and inlet opening connects water inlet pipe, and water inlet is close to groove floor; Base and staving are tightly connected, the groove of base is just in time stuck in staving, spilling water parts are held in staving upper end, and spilling water member internal walls is concordant with staving upper end, and cave in into one around the water storage tank of staving to away from staving direction to downward-extension, water storage tank has a water guide road, water in water storage tank can be derived spilling water parts, the horizontal notch of water storage tank is lower than staving upper end, and top cover is latticed, when using state, top cover is buckled in staving upper end.
The present invention's beneficial effect compared with prior art:
The present invention is by spending perch south parent population to pass through, prolonging light time, variations in temperature stimulation, salinity altercation stimulation etc. regulate and control gradually, to promote southern parent population gonad development, the sexual maturity time of southern parent population is made to be advanced to 10-12 month by 11-1 month, illumination is reduced to northern parent population simultaneously, low temperature is cultivated, delay parent population gonad development, make to spend the sexual maturity time of perch north parent population to delay to the 10-12 month from the 9-11 month.Thus southern parent population is synchronous with northern parent population gonad development, and synchronous ovulation and product essence.
Special hatching apparatus of the present invention arranges smooth ball in base to be disperseed current, weaken the impulsive force of current, prevent fertilized egg sustaining damage, whole hatching apparatus is interior without dead angle simultaneously, avoid conventional incubation device and hatch dead angle because current freely easily do not cause, or because fertilized egg overstocking causes dead ovum, bad ovum, improve hatchability of fertile eggs.
