Description
Technical field
The present invention relates to cyclic culture technical field more particularly to a kind of cultural methods of circulating water pool cultivation grisped grass carp.
Background technique
It is to be Zhongshan City, Guangdong Province the Changjiang river reservoir that grisped grass carp, which originates in, is the mineral water with reservoir, feeds concentrated feed with work
Name spy's aquatic products that watertight collection cultivation method is brought up.Gain the name because of solid, salubrious, the crisp mouth of its meat, raise come fish, outside shaped like
It is old, but meat has become, and the more common grass carp of protein is high by 12%, and taste is more delicious, and meat of also having is smooth, sharp and clear distinguished
Feature, it is especially best with fish maw part.The Electronic Speculum observation result of collagen also indicates that in grisped grass carp and common grass carp muscle, crisp meat
Grass carp stromatin, fribrillin and collagen compared with common grass carp are higher by 60.9%, 18.7% and 36.7% respectively.
The cultivation of existing grisped grass carp closely cultivates in reservoir, low output, and it is interior there is no output, therefore need to study one
Ground cultural method in kind.
Summary of the invention
Present invention aim to address above-mentioned deficiencies, provide a kind of cultural method of circulating water pool cultivation grisped grass carp.
A kind of cultural method of circulating water pool cultivation grisped grass carp provided by the invention, comprising the following steps:
Step 1, aquaculture pond is built: building rectangular aquaculture pond, the centre of aquaculture pond is equipped with partition, the both ends of partition and cultivation
The inner wall in pond does not contact, so that forming the water space of annular in aquaculture pond, the two sides of aquaculture pond are equipped with motor, the output of motor
End extends in aquaculture pond and is connected with rotation plectrum, and rotation plectrum protrudes into water body hereinafter, the direction of rotation of rotation plectrum is identical,
Rotation plectrum rotation enables to the water body in aquaculture pond to circulate around partition, forms the runway with flowing water flow, cultivation
Bottom of pond is equipped with sewage draining exit, and aquaculture pond side is equipped with the filler pipe of external water source；
Step 2, fry cultivates: injecting water in aquaculture pond, 3-5 meters of the depth of water, chooses disease-free grass carp, grass carp size is 3-5
Kilogram, then grass carp of the appearance without wound, the salt water washing bath 10-15min for being 3% with amount of substance concentration before putting in a suitable place to breed throws grass carp seedling
It puts into aquaculture pond, breeding density is 40-50kg/ square metres, and fry launches special feed in the morning, afternoon and evening three times daily after putting in a suitable place to breed, often
Secondary feeding volume is the 0.8-1% of fish body weight；
Step 3, it manages: opening motor and drive rotation plectrum rotation, so that water flow inside circulates, stirred by rotating plectrum
Water flow oxygenation；Oxygen content is kept to carry out oxygenation by aerator when oxygen content is lower not less than 5mg/L；Temperature of cultivation is kept
At 20-25 °C；And it periodically removes contamination；
Step 4, disinfection and sterilization: full pond is sprayed using copper sulphate, mixture of ferrous sulfate, monthly one to twice.
Further, special feed described in step 2 includes following parts by weight of component: 50-60 parts of bud semen viciae fabae, fermentation
10-15 parts of dregs of beans, fermentation rapeseed meal 5-8 parts, 5-8 parts of dehulled soybean meal, 5-6 parts of soya-bean oil, 3-5 parts of rice sprout, 2-3 parts of cake-shaped rape seed dregs, EM bacterium
0.6-0.8 parts.
Further, special feed described in step 2 includes following parts by weight of component: 60 parts of bud semen viciae fabae, fermentation beans
12 parts of the dregs of rice, fermentation 5 parts of rapeseed meal, 6 parts of dehulled soybean meal, 6 parts of soya-bean oil, 4 parts of rice sprout, 2 parts of cake-shaped rape seed dregs, 0.7 part of EM bacterium.
A kind of cultural method of circulating water pool cultivation grisped grass carp provided by the invention, has the following beneficial effects:
1, aquaculture pond uses circulating water pool, by the circulation runway of flowing water manifold adult fish, so that grisped grass carp is in breeding process
In be in long-term motion state, increase the quality of grisped grass carp, increase the collagen content of grisped grass carp；
2, water circulation flows, and increases the oxygen content of water body, so that the grisped grass carp death rate in breeding process is low, improves yield；
3, special feed is arranged in pairs or groups by plurality of raw materials, solves the problems, such as that bud semen viciae fabae is difficult to be digested by fry, treated bud
Changing semen viciae fabae can easily be assimilated by fry；
4, by regular disinfection and sterilization, fish morbidity is reduced or avoided, improves the survival rate of fry.
