Description
Technical field
The present invention relates to crab cultivation field, and in particular to a kind of method of pond culture crab.
Background technology
Crab because its nutrition is high, delicious flavour and it is favored by consumers.With the improvement of living standards, the consumption of crab
It is and growing.Pond culture crab becomes the social connections of having got rich of friend peasant.Certainly, pond culture crab needs necessarily
Technology, while also to understand some management measures.
Crab is generally lived in more moist environment, has higher requirement for the water quality of growing environment, cultivates crab
The water quality that breeding environment is tackled during crab carries out cleaning, and the more luxuriant water plant of arrangement, enables the small-scale activity of crab,
Because the habits and customs of crab are usually to hide by day and come out at night, basic activity is exactly to dig cave,
This is not only the habits and customs of crab, and a kind of basic technical ability, mode of resisting the enemy.Therefore, in arrangement breeding environment
When need to carry out the preparation of this respect.
The content of the invention
The invention mainly solves the technical problem of providing a kind of method of pond culture crab, can be improved according to this method
The practical value of crab cultivation, improves the quality of aquaculture.
The technical problems to be solved by the invention are realized using following technical solution：
A kind of method of pond culture crab, it is characterised in that selection is had abundant water resources, free of contamination pond, is cleaned up the pond using dry method
Disinfection, with quick lime or bleaching powder slurrying full pool spilling head, launches organic humus and makees fertilizer；Equipped with annular Ji Xiegou, on the bank and
There are water plant and the things concealed of abundance in phytal zone；Selection plastic film builds anti-escape wall, and crab net is blocked being set into discharge outlet.Select crab
Seedling, is put in a suitable place to breed in sunny fair weather, is first soaked before launching with saline solution, is then placed on the bank juvenile crab, allows it slowly to climb
Enter in water.In raising early period and later stage, based on animal fodder；Mid-term is based on plant feed.Daily feeding management will
The pure and fresh alkalescence transparent, water plant is luxuriant of water quality or neutral waters are asked, with quick lime water transfer, water cannot be changed during crab shell；
Fungi, bacteriosis can be prevented with quick lime or bleaching powder；Carry out immunoprophylaxis with subunit vaccine, should mid-September extremely
Crab is all caught out at the beginning of 10 months.
Wherein：（1）The preparation in pond is as follows：
Selection is had abundant water resources, free of contamination pond, in mid or late April, is retained bottom of pond 7-10cm water, is given birth to stone with 80-100kg per acre
Ash or 10-15kg bleaching powder slurrying full pool spilling heads, dry method are cleaned up the pond disinfection；Organic humus is launched after 3-4h and makees fertilizer, after 6-8d
Juvenile crab can be put in a suitable place to breed, while water quality is cultivated with fermentation muck；Depth of water 0.8-1.5m in pond when putting in a suitable place to breed, and it is equipped with annular Ji Xiegou, bank
There are water plant and the things concealed of abundance in upper and phytal zone；Selection plastic film builds anti-escape wall, and plastics lower end is embedded to 15- in soil
25cm, ground 60-70cm, block crab net being set into discharge outlet, are covered with wire netting.
（2）Putting in a suitable place to breed for juvenile crab is as follows：
Selection crust is complete, creep the juvenile crab that active, limbs perfect, and at the beginning of 5 months at the beginning of 4 months, selects sunny fair weather, puts in a suitable place to breed
Then juvenile crab, is first placed on the bank with the saline solution immersion 6-15min of 3-5% before launching, slowly climbed into water by be allowed it by crab seedling,
Crab specification is 200-250/kg, and throw-in density is 3-6kg per acre.
（3）Feeding for feed is as follows：
In raising early period and later stage, based on animal fodder, account for 60-70%, animal fodder have small fish, shrimp, freshwater mussel meat,
Silkworm chrysalis, fish meal, insect larvae, water earthworm；Mid-term accounts for 60-70% based on plant feed, and plant feed has browse, mountain
Taro, pumpkin, bean dregs, wheat bran, rice bran；Feed daily morning and evening, day feeding rate accounts for the 5-10% of crab gross weight.
（4）Daily feeding management includes Water-quality control and adjusting, disease control：
Water-quality control and adjusting：It is required that the pure and fresh alkalescence transparent, water plant is luxuriant of water quality or neutral waters, dissolved oxygen content >=
5mg/L, every 10-15d water filling 15-20cm, uses the water transfer of 10-15kg quick limes once, during crab shell per acre per 15-20d
Water cannot be changed；
Disease control：Fungi, bacteriosis can be prevented with 15-20kg quick limes or 0.8-1g/L bleaching powder per acre, with sub- list
Position vaccine carries out immunoprophylaxis, good immune effect.
（5）Crab should all catch out at the beginning of mid-September to 10 months, and catching method is as follows：
The habit debarked using crab 9-10 month breeding migrations, is caught with hand；Water quickly is drained, crab is picked up on the dry pool；Utilize ground
Cage net is caught.
The present invention reaction mechanism and have the beneficial effect that：
Have water plant and the things concealed of abundance with phytal zone on the bank in pond, easy to crab it is hidden, look for food, inhabit and ejection；Pond
Illumination is sufficient, lighting surface is big, be conducive to planktonic organism growth, breeding and oxygenation；PH improvement water can have both been adjusted with quick lime
Matter, and increase the content of calcium in water, it is beneficial to crab shell；In the whole growth phase of crab, except manually being trained using in pond
Outside the water plant and benthon educated, animal fodder and plant feed are also manually fed；Can with quick lime or bleaching powder
Fungi, bacteriosis are prevented, immunoprophylaxis, good immune effect are carried out with subunit vaccine；It should be incited somebody to action at the beginning of mid-September to 10 months
Crab all catches out, and when water temperature is low, crab will pierce overwintering in cave, it is difficult to catch.
