Description
Technical field
The present invention relates to organic grass carps to be segmented cultural method technical field, is specifically related to a kind of organic grass carp segmentation cultivation
Method.
Background technique
Grass carp is also referred to as grass carp, is one of China " four large Chinese carps ", is a kind of typical herbivorous fishes, full of nutrition, egg
White matter content is high, rich in microelements such as copper, phosphorus, and has the speed of growth very fast, adaptable, the high feature of yield is
The main edible protein source of the general common people, so more and more raiser takes a broad view grass carp cultivation, the mode of cultivation and
The feed of nursing is more diversified, and purpose is provided to reduce aquaculture cost, improves yield, pursues high economic effect simply
Benefit is in big bag shape, figure tubbiness so as to cause the grass carp mostly fish body of artificial breeding, and fat content is high, and meat is loose, mud fishy smell
Weight, or even it is not also able to satisfy requirement of the majority of consumers to green ecological aquatic products infected with various insect pest germs.
Summary of the invention
1. technical problems to be solved
The purpose of the present invention is to provide a kind of organic grass carps to be segmented cultural method, to solve to propose in above-mentioned background technique
The problem of.
2. technical solution
To solve the above problems, the present invention adopts the following technical scheme that:
A kind of organic grass carp segmentation cultural method, including seedling culture stage and adult fish culture stage, include the following steps；
S1 cultivates addressing；In mountain spring water, cultivation base is built without the periphery of any pollution source area in flourishing and periphery；
The construction of the pond S2；Seedling culture pond and adult fish culture pond, the pond deep 1.5 in seedling culture pond are dug in cultivation base
~2 meters, 1~1.5 meter of the depth of water, the pond in adult fish culture pond is 3~4 meters deep, and 2~2.5 meters of the depth of water, and supported in seedling culture pond and adult fish
It grows and perfect row's flood pattern and aerator is set inside pond, it is desirable that row's flood pattern introduces seedling training after capable of filtering mountain spring water
It educates pond and adult fish culture pond, water behind seedling culture pond and adult fish culture pond self-filtering can be discharged；
The S3 seedling culture stage；Fingerling must be sterile-processed before being put into, and can be selected chlorine dioxide every 5~10 minutes 20~40
Every 5~20 minutes of mg/litre, salt with 1%~3%, every 15~30 minutes with 8 mg/litres, potassium permanganate every 15~30 minutes
The disinfection of the drug immersions such as 10~20 mg/litres, after disinfection treatment, while Grass Carp Juveniles are put into seedling culture pond, also puts
Enter crucian, it is 5: 1 that ratio is supported in the throwing of Grass Carp Juveniles and crucian fingerling, and feeding takes soya-bean milk of splashing, the mode of feed to feed, daily
It feeds 4~5 times, day feeding volume is 4%~6% of fingerling weight in pond, fully ensures that fingerling is ingested, and in every afternoon 1~3
Shi Kaiji oxygenation 1 hour, new water was filled every 5~7 days 1 time, adult fish culture pond is introduced when fingerling grows to 250 grams and is supported
It grows；
The S4 adult fish culture stage；Feeding is fed, 3~4 with feeding based on green grass with feed that the mode supplemented by feed arranges in pairs or groups
Month 3 times a day, i.e. morning 8~9 point, noon 11~12 point and afternoon 3~4 point, 5~September part 4 times a day, i.e. morning 8~9
It feeding every time 30 minutes or so in point, noon 11~12 point, afternoon 1~2 and 3~4, feeding volume is had enough with 80% grass carp to be advisable,
And before feeding, the residual bait that do not eat up after last time feeding in net pond is first fished out, is switched on oxygenation 2 hours at every afternoon 1~3,
Morning in due course oxygenation, continuous cloudy day should do sth. in advance oxygenation, fill new water to pond in due course, take " float small into, repeatedly change water "
Method step by step control water quality, while being carried out disinfection processing with quick lime to water quality every two weeks, transparency cannot be below 40cm, pass through
Harvesting lists after crossing cultivation in 4 years.
Preferably, the Grass Carp Juveniles launched in the seedling culture stage are greater than the specification of crucian fingerling.
Preferably, the seedling culture stage is made of with feed in the adult fish culture stage the raw material of following percentage；Fish
Powder 8%, soya-bean cake 16%, rapeseed cake 15%, wheat bran 30%, wheat-middlings 10%, rice bran 18% and premix 3%.
Preferably, in the adult fish culture stage according to spreading 10~15 kilograms of quick lime per acre to carrying out disinfection in pond.
Preferably, seedling culture pond and adult fish culture pond are rectangle in the pond construction, and bottom of pond is loam.
Preferably, it in the adult fish culture stage when green grass material deficiency, mends and feeds the fine fodders such as barley, wheat, paddy, soya-bean cake,
And when feeding the grains material such as barley, paddy, with bubble it is swollen after feeding again.
3. beneficial effect
1, present invention introduces mountain spring waters to cultivate grass carp, and the grass carp of cultivation is pollution-free, be able to satisfy people to organic grass carp ecology,
The requirement of health, and the grass carp fish cultivated out is physical strong, delicious meat is delicate, it is full of nutrition, and there is no bilgy odour, it firmly gets
The welcome in market, in high-end market, supply falls short of demand for a long time.
2, the present invention to be to feed based on green grass, is fed with feed that the mode supplemented by feed arranges in pairs or groups, feeds grass carp and like eating
Forage grass, can guarantee cultivation obtain the grass carp bodily form it is slender, fat content is low, and meat is compact fresh and tender, has wild-type grass carp
Delicious mouthfeel, more green ecological, feed assisting in feeding can improve Growth of Grass Carps Ctenopharyngodon Idellus speed to the greatest extent, reduce cultivation week
Phase, to reduce aquaculture cost.
