2) sterilization of the culturing pool, the deep water of 70~90cm is injected into the culturing pool, ozone is passed through and carries out disinfection,
Pathogenic microorganism or fish-egg etc. are killed；
3) water is educated at training bottom, and decomposed excrement and wormcast, inoculation chlorella, small ring algae, hidden algae are added into the culturing pool
And photosynthetic bacteria, cultivate 15~20 days；
4) loach fry is put in a suitable place to breed, selects physical strong, and body colour is bright, neat specification, a length of 5~6cm of body high-quality kind
Seedling, 5~10min is soaked using 4%~5% saline solution, is selected in put the culturing pool in a suitable place to breed in the morning of fine day, toward water flea
Zoea is inoculated with culture pond；
5) feeding management, loach seedling respectively feed an autogamy feed in the morning, afternoon and evening daily after launching 2~3 days, and water colour is transparent
When degree is less than 10cm, zoea is launched into the water flea culture pond, when water colour transparency is higher than 20cm, toward the culturing pool
Middle to add decomposed excrement and wormcast, lasting cultivation obtains the loach.By regulating and controlling water colour, make microalgae in culturing pool all the time
Higher productivity is kept, water flea is obtained higher yield so as to reduce the feeding volume of feed.
Preferably, the pond depth of the culturing pool is 100~120cm, and the area of the water flea culture pond accounts for the cultivation
Pool area is 25%~35%, and the distance between the bottom plate and culturing pool bottom sludge of the water flea culture pond is 30~40cm, institute
The mesh number for stating filter screen is 300~350 mesh, and unilateral gate pyramidal structure made of filter screen, the tip of the unilateral gate is provided with
Water flea is fixed on the water flea and escaped from hole by hole, the opposite side of the unilateral gate.In culturing pool, water flea culture pond is added
Cultivation water flea can promote the algae in water body update, make the more vigorous growth rate of algae holding, and the water flea in water flea culture pond is close
When degree is higher, water flea can escape from the bait for being used as loach into culturing pool by unilateral gate, reduce feed cost.
Preferably, when the water-bed dissolved oxygen of the dissolving oxygen detector detection is less than 4mg/L, to electric-controlled switch output first
Signal, makes electric-controlled switch start waterwheel aerator work, and the dissolving oxygen detector detects water-bed dissolved oxygen and is more than 6mg/L
When, secondary signal is exported to electric-controlled switch, electric-controlled switch is stopped waterwheel aerator work.It is real-time by dissolving oxygen detector
Monitor and regulate and control the oxygen concentration of culturing pool bottom, the dissolved oxygen in culturing pool water body is in higher level all the time, avoid
Water quality deterioration caused by water hypoxia damages caused by anoxic is to loach body.
