Abstract
The invention discloses a method of promoting synchronous sexual maturation in male and female parents of Brachymystax lenok. The method includes 1, controlling the water temperature of a culture system by stages during parent fish rearing; 2, adjusting feed according to different growth stages of parent fishes. According to biology and ecological habits of the Brachymystax lenok, the method fully conforms to the environmental conditions of wild state in terms of water environment and feed structure by applying bionic technology during the period of parent fish domestication and cultivation; different feeds are used for strengthening cultivation during the different developmental stages, the water temperature and water flow are controlled, and accordingly ecological cultivation under artificial domestication is achieved; finally, the male and female parent fishes synchronously develop gonadally, and artificial spawning and fertilization can be performed smoothly.
Description
Technical field
The present invention relates to one and impel the synchronous sexually matured method of fine-scaled graphite male and female parent population.
Background technology
Fine-scaled graphite is one of fish of China's high and cold area special product, and also only this genus is a kind of in the world, and its meat flavour is fertile, fat content high (3.8% ~ 7.7%), and nutritious, ovum is also quite famous and precious, is a kind of famous and precious economic fish.In the last few years, due to the destruction of natural ecological environment and the interference of human factor, the resource quantity of fine-scaled graphite is reduced year by year, now listed national second class protection animal in.The artificial breeding of fine-scaled graphite just lists country and the key scientific and technological projects about provinces and cities in as far back as earlier 1900s; most research unit is all because male and female parent population grows asynchronous; thus artificial breeding can not form industrialization, certain difficulty is brought to the protection of wild fish and resource recovery.
In the domestication and cultivating process of brachymystax lenok parent fish, how to make male and female parent population energy synchronous ripe, be one of key technology solving fine-scaled graphite artificial breeding, as long as accomplish that male and female parent population can be synchronously ripe, realizes fine-scaled graphite scale seed breeding and just likely become a reality.In order to reach scale and the industrialization of fine-scaled graphite Seedling production, the subject matter in parent fish rearing must be solved, in all researchs in the past, all because grow asynchronous in male and female parent fish rearing process, early male parent population is ripe or male parent population is immature to cause female parent population, thus formation carries out artificial insemination without male semen, the cultivation unit that some parent population is many, take the method for dissecting, processed by corresponding technological means, so not only cause the waste of wild brachymystax lenok parent fish, also be that wild resource not only can not get recovering, and define larger destruction.
Summary of the invention
The object of this invention is to provide one and impel the synchronous sexually matured method of fine-scaled graphite male and female parent population.
The technical solution used in the present invention:
One impels the synchronous sexually matured method of fine-scaled graphite male and female parent population, comprises the steps:
(1) in the water temperature of parent fish rearing phase control by stages cultivation system, specifically comprise the following steps:
Control cultivation system water temperature 10-20 DEG C 6-8 month, control cultivation system water temperature 9-10 month at 5-10 DEG C, November, the parent population to Second Year was hastened parturition the stage, and the water temperature controlling cultivation system is 0-4 DEG C;
(2) different according to parent population growth period adjustment bait, specifically comprises the following steps:
6-8 month, based on pellet of throwing something and feeding, is aided with appropriate small fish alive, and wherein the day feeding volume of pellet is the 3-4% of parent population body weight, and the day feeding volume of small fish of living is 1% of parent population body weight; 9-10 month, based on fresh and alive small fish of throwing something and feeding, is aided with appropriate pellet, and wherein feeding volume is the 4-5% of parent population body weight fresh and alive small fish day, and the day feeding volume of pellet is 2% of parent population body weight; November, the parent population to Second Year was hastened parturition the stage, throw something and feed fresh and alive small fish and live fresh water clam worm or water earthworm, day feeding volume be the 7-8% of parent population body weight.
In described method, in cultivation system, the cultivation density of parent population is 5-8 tail/m
2.
Cultivation system water temperature is controlled by regulating water flow in step (1).
In step (2), small fish is mainly the loach, La Shi Minnow etc. that local mountain stream produces, live small fish or chilled small fish, and sea water and fresh water produces, and body is long is less than 10cm, soaks half an hour, throw something and feed after cleaning after chilled small fish thaws with 1% terramycin.
The present invention is according to the biology of fine-scaled graphite and ecological habit, in domestication and the nurturing period of parent population, adopt Ecology technology, water environment and food structure meet the environmental condition of wild state completely, in different developmental phases, adopts different bait to carry out reinforced cultivating, in conjunction with the control of water temperature, current, reach the biological breeding under artificial domestication condition, finally reach male and female parent population sexual gland and synchronously grow, and carry out artificial induced spawning, fertilization smoothly.Female parent population maturing rate 90.58% is studied, male maturing rate 100% through 2 years.The ripe sync rates of male and female parent population reaches 100%.
