Description
Technical field
The invention belongs to technical field of aquaculture, particularly relate to ecologically breeding river crabs method.
Background technique
Crab is also known as river crab, is fresh water crustacean, grows up in fresh water, and river crab meat flavour is delicious, full of nutrition.River crab mesh
It is preceding by Chinese and the universally recognized cuisines of overseas people.Culture of Chinese mitten crab production on, also have been achieved with from quantity velocity profile to
The transformation of quality and efficiency is changed from " big crab farming " to " bringing crab up ", has especially more been focused on ecological, safe and environment-friendly, strong
The cultivation of health, nuisanceless aquatic products, it is also higher and higher to the quality requirement of aquatic products.
For now, simple pursuit in the past that high density launch, the small dimension commodity crab of high yield, there is no
Competitive advantage, in response to the market demand, it is difficult to sell discomfort, and market price is low, and culture efficiency is poor.Demand currently on the market
It is the high-quality crab of high quality, big specification, and is also the trend of development, not only product is fast-selling for it, and price is high, cultivation effect
Benefit is good.Crab has been supported, has brought crab up, has supported high-quality crab, has supported health crab, has supported nuisanceless crab it is necessary to carry out the breeding way of health.It is so-called
Healthy aquaculture refers to the biological property according to river crab, and crabs production is instructed with ecological principle, and as river crab builds one
A good ecological environment for being conducive to river crab growth and development, makes river crab reduce disease to the maximum extent during growth and development
Occur, the commodity crab formed.Pollution-free, individual is big, and the full cream fertilizer of Huang has good quality.Carry out innoxious management, it is ensured that river crab
It cultivates the whole quality safety from pond to dining table and people is allowed to be able to eat the high-quality crab trusted.Only in this way, product could be in great demand
Without hindrance, enterprise can just develop, the economic benefit and social benefit that cultivating river crab could obtain.
Currently, the technology of artificial cultured river crab is also rear many insufficient, people are still not perfect the experience of artificial crab farming.Cultivation
The bait that river crab needs in the different stages is different, and the growing environment needed is also different, and many technical staff are in cultivating river crab
The scientific offering for ignoring culture of Chinese mitten crab ecological environment, using industrial fits feed, blindness medication causes the broken of river crab ecologic environment
It is bad, cause river crab survival rate low, quality decline.
Summary of the invention
The purpose of the present invention is to provide ecologically breeding river crabs method cultural method, high survival rate, cultivation soft-shelled turtle quality compared with
It is good.
The technical scheme of the present invention is realized as follows:
Ecologically breeding river crabs method, includes the following steps:
S1: surrounding green cover area is selected, as cultivation ground, to control highest on daytime in the natural river embankment of 80-90% range
Water temperature is in 24-28 DEG C of range, and night minimum water temperature is at 13-18 DEG C, and for average dissolved oxygen amount in 4.4-4.6 mg/litre range, bottom of pond is molten
For pH value in 7.2-7.5 range, transparency is minimum in 40-50 cm range, ammonia nitrogen in 5.3-5.5 mg/litre range, water for oxygen amount
Content up to 0.14-0.16 mg/litre range, bed-silt thickness is in 6-8 cm range；
S2: water plant plantation: dispersion plantation water plant Yi Le grass, Monochoria vaginalis and hydrilla verticillata in pond, so that water plant covers
Rate is 60-70% in the middle and later periods, and spiral shell, a species of small clam living in fresh water, freshwater mussel, flower clam are launched in pond, allows its natural growth reproduction, provides day for river crab
Right feed；
S3: river crab seedling is cultivated 2-3 days before putting in a suitable place to breed using dipped cross of the Biological water prepared；
S4: night is thrown to river embankment, and injected volume is 500-600/mu；
S5: being fed using artifical compound feed, is launched the 2-3% that initial stage daily inventory is crab weight, is thrown in 7-9 month
Doses is the 4-6% of crab weight, and inventory is the 6-8% of crab weight after September part, launches first 7 days and feeds 1 time daily, Feeding time
It when for late 5-7, is fed daily 2 times after 7 days, when Feeding time is morning 7-9, when late 5-7, early, late injected volume ratio is 1:2；
S6: water quality management: summer daily noon aerator oxygenation 2-3h is filled to water level 1.4-1.6m, autumn water level is
1.1-1.3m, season in spring and autumn, pond are monthly changed water 1 time, were changed within summer every 5-7 days water 1 time, and each quantity of exchanged water is the 30- of water
40%.
Preferably, salt content is 0.12-0.14% in Biological water, potassium permanganate content is 0.03-0.05%, methylene
Blue content is 0.01-0.03%.
Preferably, the artifical compound feed is made of following component in parts by weight: 50-60 parts of pumpkin, soya-bean cake 40-
45 parts, 35-40 parts of Radix Angelicae Sinensis, 3-5 parts of Radix Curcumae, 20-25 parts of brown rice, 15-20 parts of motherwort, 10-15 parts of fish meal, snail meat 10-12
Part, 8-10 parts of peppermint.
In conclusion the present invention has the advantages that
Ecologically breeding river crabs method of the invention, cultural method of the present invention is scientific and reasonable, can be improved the survival rate of river crab,
Effectively common disease occurs in prevention culture of Chinese mitten crab, cultivate it is big, physically fit at crab specification, yield is high, have compared with
Good economic benefit of aquaculture.
