Abstract
The invention relates to a loach parent incubation tank system. The system comprises a separation tank and a collection tank, wherein a screen net used for accommodating loach parents is vertically placed on the surface of a water layer in the separation tank, and meshes of the screen net can prevent the loach parents from passing through the screen net; a water outlet is formed in the bottom of the separation tank; the height of the collection tank is smaller than that of the separation tank; a water inlet is formed in one side of the collection tank and communicated with the water outlet of the separation tank; sieving silk gauze is mounted at the water inlet, and meshes of the sieving silk gauze can prevent fertilized eggs from passing through. The invention further relates to an inoculation method. The loach parents with eggs and sperms taken out are put in the separation tank, all the loach parents are sexually mature after a period of temporary rearing and then are put back to a culture pond, all the sperms and the eggs of the loach parents are released and are effectively separated from the parents, the incubating rate is increased, benefits are increased, the inoculation operation is simple, and cultivation management is facilitated.
Description
Technical field
The present invention relates to a kind of loach parent hatchery system and hatching m, belong to technical field of aquaculture.
Background technology
Loach is the important characteristic aquaculture kind of China, and its per mu yield Benefit, adult fish not only domestic market sales is well sold and in short supply, also deeply welcomes by markets such as Japan and Korea S.Therefore, loach becomes the backbone kind of China's aquaculture industry just day by day.Loach fry raising technology is the prerequisite that cultivation obtains enough seeds.The artificial propagation techniques key step generally adopted at present has manual injection's oxytocins, take out ovum and sperm, sterilization, artificial insemination, put into and cultivate pond and hatch seedling etc.By strict standard operation; this technology can ensure to obtain higher seedling incubation rate; but still have larger room for promotion; main cause is that loach leans on manual injection's oxytocins can not reach sexual maturity simultaneously; therefore often there will be some parent and can not get sperm or ovum, and the phenomenon having seedling to bring out after being put back to culturing pool.This situation obviously reduces culture benefit, is also unfavorable for aquaculture management.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, there is provided a kind of loach parent hatchery system and hatching m, it can guarantee that the sperm of loach parent and ovum are all discharged, and is effectively separated with parent, be convenient to aquaculture management, improve incubation rate.
