Abstract

The present invention relates to the field of the industrial aquaculture of turbots, which has the technical characteristics that seawater with the depth of 2 to 4 meters is injected into a circular reinforced concrete spawning pond, light shielding cloth with the shielding rate of more than 95% is covered on the top of the pond, female turbots and male turbots are put in the spawning pond according to the density of 6 to 30 turbots per hectostere of water, and the ratio of male to female is 1: 2; the water temperature in the spawning pond is kept between 11 to 16 DEG C, an artificial light source with the intensity of 600 to 1500 lx is adopted to irradiate the spawning pond for 12 to 16 hours per day, fresh fingerlings are thrown and fed to the spawning pond every day, water is changed regularly and quantitively, and the quantity of the changed water is 3 to 5 times.

Description

The cultural method of turbot natural spawning
Affiliated technical field
The present invention relates to a kind of cultural technique of industrial fish farming, especially the cultural method of turbot natural spawning.
Background technology
Turbot belongs to the deep-sea cold water fish, at present, can reach maturity propagating under the condition (general water body is little, density is high) artificially, but can not normal spawning, must cultivate the big water chestnut young by artificial crowded ovum, insemination, but the fertilized egg quality fluctuation that adopts artificial crowded ovum, the method for fertilization to obtain is very big, and easily parent population is damaged.
Summary of the invention
For overcome existing turbot artificial culture can not natural spawning deficiency, the invention provides a kind of cultural method of propagating the turbot natural spawning artificially, this cultural method turbot not only can be grown by normal growth, and the turbot of individual body maturation can natural spawning.
The technical solution adopted for the present invention to solve the technical problems is: the turbot spawning pond adopts armored concrete to build up circular pond, and the pond is 2-4 rice deeply, the shading of top, pond, and shading rate is more than 95%, and it is gap that the pool wall on spawning pond water inlet pipe opposite leaves Ji Luankou; Male and female turbot parent population is put into the spawning pond of filling with seawater to be cultivated, the breeding density of turbot is every hectostere water body 6-30 tail, the male and female ratio is 1: 2, with light intensity is that the 600-1500lx artificial light source carries out Artificial Control illumination to spawning pond, light application time is 12-16 hour every day, and pond maritime interior waters temperature is controlled at 11-16 ℃, the fresh small fish of throwing something and feeding every day, site-directed quantitative changes water, and quantity of exchanged water is 3-5 times; After raun had two ovaries to expand, the turbot parent population just can lay eggs successively.The present invention imitates the turbot natural ecological condition, utilizes big water body, low-density to culture, thereby reach the purpose of inducing its natural spawning.
The invention has the beneficial effects as follows, can pass through Artificial Control, turbot is reached maturity in the industrial artificial breeding process and spontaneous ovulation.
The invention will be further described below in conjunction with embodiment.
Embodiment one: building up volume with armored concrete is 130m 3, the pond is 3 meters turbot spawning pond deeply, the very useful gobo shading in pond, shading rate is more than 95%, leaving Ji Luankou in the pool wall upper end on spawning pond water inlet pipe opposite is gap, collects the come-up ovum from here; Selecting the female turbot of three tails, the six tails brill great and mighty or powerful of forming 3 years puts into above-mentioned spawning pond and cultivates, take Artificial Control illumination, the light intensity of artificial light source is 1000lx, light application time is 14 hours every days, ocean temperature in the spawning pond is controlled at 11-16 ℃, the an amount of fresh small fish of throwing something and feeding every day, every day, site-directed quantitative changed water, and quantity of exchanged water is at 3-5 doubly; Observe parent population, after raun had two ovaries to expand, beginning is ovulation successively, between the egg-laying period, can observe a kind of special act, the raun of being clung on one's trail by milter, leave at the bottom of the pond that different depth moves about around pool wall in water, occasionally milter swim near the top of raun or below, harmonious together moves about.Raun gets back at the bottom of the pond after a few minutes, and milter just is parked in neighbouring or covers on the raun.According to the method described above, just artificially the ovum that obtains turbot nature output under the condition can propagated.
The present invention also can culture by the listed embodiment numerical value of following table, and other breed Step By Condition is identical with embodiment one.Depth of water unit is: rice, and intensity of illumination unit is: lx, light application time unit is: hour/every day, raun density singly is: tail/every hectostere
The depth of water Intensity of illumination Light application time Breeding density
One ????2 ??1500 ??12 ??6
Two ????3 ??600 ??16 ??12
Three ????3.5 ??800 ??13 ??18
Four ????4 ??1200 ??14 ??30
