In, breeding density is 10,000 tails/m2；
Culturing pool management：Every morning 8-9 points, noon 12-1 points and 5-6 points in afternoon, feed bait, the bait includes
Yolk, soya-bean milk, wheat flour, earthworm powder, fairy shrimp and wheel animalcule, the bait feeding amount are the 2-5% of seed total weight；
Water quality management：9 points of every morning and at 7 points in evening more renew water in culturing pool, and quantity of exchanged water is culturing pool total Water
1/4, timely soil pick-up when discovery has dirt；
Pond disinfection：By seed from culturing pool move to pond before 5-10 days, the water in pond is drained, with the life of 50kg/ mus
Lime carries out disinfection to pond；
Seed is launched：After seed is cultivated 6-10 days in culturing pool, take out, be placed in the first bactericide and soak 10-15min
Afterwards, pond is put into, breeding density is 200,000 tails/mu；
Pond manages：Seed is put in a suitable place to breed to pond, feeds mixed fodder, the mixed fodder is by animal fodder and manually
Mixed feed is 3 in mass ratio:1 composition, the animal fodder include small fish and shrimp, water earthworm and fish meal, the hand fit
Feed includes dregs of beans, wheat bran, corn flour and vitamin, and the feeding volume of mixed fodder described in winter and summer is loach total weight
1-3%, the feeding volume of mixed fodder described in spring and fall are the 5-10% of loach total weight.
Preferably, in described loach fry breeding method, first bactericide by following parts by weight component
It is made：Tea Polyphenols 2-3 parts, lysozyme 0.5-1 parts, chitosan 1-2 parts, pyrolkigneous liquid 10-15 parts and water 50-70 parts.

Comparative example
Beneficial effects of the present invention are further illustrated by comparative example.Mud fish fry is cultivated in the method for embodiment 1 to 5
Kind, the growing state of loach is shown in Table 1.
As it can be seen from table 1 spray medicine using liquid box is got rid of so that evenly, preventing and treating is more comprehensively, more thorough for herbal sprinkling
Bottom, the survival rate of loach different times is higher, and the loach for infecting pest and disease damage is less.The 5-10 months are killed using ozone to pond
Bacterium, pest and disease damage odds can be reduced so that the survival rate of loach is higher.
Although embodiment of the present invention is disclosed as above, it is not restricted in specification and embodiment listed
With it can be applied to various suitable the field of the invention completely, can be easily for those skilled in the art
Other modification is realized, therefore under the universal limited without departing substantially from claim and equivalency range, it is of the invention and unlimited
