Description
Technical field
The present invention relates to technical field of aquaculture, particularly relate to a kind of lobe knot pool, fishpond artificial cultivating method.
Background technology
Lobe knot fish belongs to Osteichthyes, Cypriniformes, Cyprinidae, Barbinae, and fish belongs to knot, lobe knot fish subgenus.Be commonly called as: Kazakhstan department, heavy mouth, Ma Zui, cured huge.Lobe knot fish is the middle lower floor fish moved in limpid flowing water, and build is streamlined, head point, and fin is good for, and do good one of fish of swimming.It passes through through being everlasting between water-bed stone riprap, sucks at the bottom of river and on stone face with tubaeform retractile large mouth, with the fragment of benthic mollusc, aquatic insect and larva thereof, plant and thread algae for food.General 3 fish beginnings age in winter reach sexual maturity, and the egg-laying period was estimated between the 6-7 month, and mature brood fish requires to breed under Condition of Supercritical Flow.
Lobe knot fish is a kind of medium-sized economic freshwater fish, and be distributed on the south ChangJiang River, Pearl River system, be the economic fish that producing region is common, it is Fresh & Tender in Texture, be people institute eating, and fat content is high, and growth is very fast, has higher Fishery value.Need now to improve a kind of pond artificial cultivating method improving lobe knot fish crop.
Summary of the invention
Based on the technical problem that background technology exists, the present invention proposes a kind of lobe knot pool, fishpond artificial cultivating method, improve lobe knot fry survival rate, can also promote that lobe is tied fish and increased weightening finish, and not pollute the environment.
A kind of lobe knot pool, fishpond artificial cultivating method that the present invention proposes, comprises the steps:
A, finishing culturing pool: selection is had abundant water resources, water quality is good, area is 667-1334m
2, the dark 1.5-2m in pond pond be culturing pool; Be provided with water inlet, discharge outlet and the microporous pipeline oxygen increasing equipment for daily oxygenation at the bottom of culturing pool, water inlet is higher than discharge outlet, and the line between water inlet and discharge outlet and the angle of horizontal plane are 4-8 °;
B, sterilization rich water: adopt bleaching powder to carry out dry disinfection, the consumption of bleaching powder is 15-18g/m
