Grass, the water surface coverage rate for controlling floating bed is 20-30%；
(3) Tilapia mossambica is put in a suitable place to breed:
After biological flocculation preliminarily forms, select physical strong, specification uniformly, without sick and wounded, weight 15-20g Tilapia mossambica fry,
It is first placed on concentration and carries out immersion 8-15min, breeding density 1000-1300 tail/mu in the saline solution of 3%-5%；
(4) feeding management:
A, water body management: at 25-32 DEG C, lasting inflation aeration maintains dissolved oxygen in 3.0mg/L for entire breeding process water temperature control
More than, Bacillus subtillis bacterium solution is shed in full pond in breeding process, shed 2-3 times weekly, at the same according to feed carbon nitrogen content with
And C/N >=10 in feeding volume adjustment aquaculture pond water body；
B, feedstuff feeding: seedling does not feed intake for first day after putting in a suitable place to breed, starts within second day to feed tilapia feed, daily respectively at 9:00
2 equivalent being carried out with 17:30 to feed, feeding volume accounts for the 3-5% of quality of fishes, and every 15-20d weighs 20 tail Tilapia mossambicas at random, according to
Quality of fishes adjusts feeding volume.
Wherein, the active concentration of the Bacillus subtillis is 1.0 × 1011cfu/g。
Wherein, the biological flocculation cultural method specifically: abundant aeration oxygen replenishing is carried out to water body in aquaculture pond, controls water
Body dissolved oxygen maintains 5mg/L-8mg/L, and temperature maintains 22 DEG C -28 DEG C, and pH maintains 6.5-8.0, continuous culture 3-6 days
Afterwards, biological flocculation initially forms.
Wherein, crude protein content C/N ratio 10:1 in 30-35%, crude fibre 10-15%, feed in the tilapia feed.
The present invention has the beneficial effect that:
Using biological flocculation technology and cordate houttuynia floating bed technology in the present invention, biological flocculation technology is by microbiologic population to cultivation
The assimilation of water body inorganic nitrogen, while cordate houttuynia is absorbable in floating bed, superfluous during assimilation pond culture nitrogen, phosphorus and having
Machine object, to achieve the effect that purify pond water quality, the biological flocculation of formation realizes bait albumen but also as forage protein
Secondary use can effectively facilitate Growth Op Tilapia and improve bait utilization efficiency；In addition cordate houttuynia is as a kind of medicinal plant, tool
Have antibacterial, it is anti-inflammatory, antiviral, increase immunity of organisms the effects of, food can be provided in Tilapia mossambica breeding process for Tilapia mossambica,
Be conducive to improve the immune performance of fish body；The advantages of biological flocculation technology and cordate houttuynia floating bed technology are combined in the present invention, to pond
Pool cultivation water has apparent regulating and controlling effect, promotes the self-purification function of water body, while can significantly improve sieve to a certain extent
Non- fish nonspecific immunity ability improves Tilapia mossambica cultured output.
