The invention relates to a river crab culturing method, and relates to an aquaculture method. The method comprises the steps of crab pond construction, crab fry stocking, feeding management, and pond crab catching. The method has the following advantages: no professional equipment is needed; no culture pollution is caused; the culturing technology is standardized and normalized; stocking is reasonable; and catching is prompt. Compared to traditional river crab culturing technologies, the method is significantly improved. With the method, river crab product yield and quality are effectively improved.

Description

The cultural method of a kind of river crab
Technical field
The present invention relates to a kind of method of aquaculture, be specifically related to the cultural method of a kind of river crab.
Background technology
River crab also cries " crab " or " eriocheir sinensis ", Arthropoda Crustacea animal.The carapace that head and chest are combined into is square circular, and quality is hard.Front end body has a pair, and side has two to very hard sharp crab tooth.Crab a pair appendage is foremost the foot of a chela, and surface covers with fine hair; 4 pairs of steps are had after the foot of a chela, flat-sided and longer; Abdominal appendage is degenerated.The male and female of river crab can distinguish from its belly: female belly is rounded, male belly is triangle, river crab due to himself nutritive value and medical value very popular, therefore also very large to my human wants, therefore the cultivation of river crab is also a lot, but due to specific life habit and the growth conditions of river crab, when cultivating, survival rate is very low, and quality is also poor, like this, attack for raiser is very large, and the enthusiasm of cultivation is not strong.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of and can improves river crab survival rate and can reduce the cultural method of the river crab of feed consumption.
Technical problem to be solved by this invention realizes by the following technical solutions.
A cultural method for river crab, is characterized in that: comprise the following steps:
(1) crab pond is built: having abundant water resources, water nonpollution, few, the many grass of mud, position at the bottom of pond comparatively build crab pond in quiet, secluded place, and area is 5-10 mu, depth of water 1-1.5 rice; Smooth and the 1:2.5-3 gradient is set at the bottom of crab pond, to delivery port lopsidedness at the bottom of pond, before delivery port, dig a circular or square collection crab kerve, groove depth 20-30 centimetre, area 10-20 square metre.
(2), crab kind is put in a suitable place to breed:
A 1, sterilization of cleaning up the pond: before crab kind is put in a suitable place to breed, Jiang Chishui drains, and roots out humus at the bottom of pond and mud, tan by the sun at the bottom of pond, remove predacious fish and soft-shelled turtle, drop into first half of the month, discharge water 5-10 centimetre at the bottom of pond, and every mu dissolves rear full pool spilling head with quicklime 75-150 kilogram, carries out disinfection.
B 1, pour water and throw grass: before putting crab kind in a suitable place to breed, will pour into new water in crab pond and throw in pasture and water, most first watering shallow water, depth of water 0.5-1 rice, deepens later gradually, throws in pasture and water after crab pond discharges water.
C 1, crab kind throws in: throw in crab kind in early spring, water temperature controls to start when 5-7 DEG C to throw in.
(3) feeding and management:
A 2, feed kind: select eel grass, hornwort, pumpkin, green vegetables, sweet potato, paddy, wheat class and corn plant feed and spiral shell, freshwater mussel, fish, shrimp, insect and larva thereof, earthworm, fly maggot, silkworm chrysalis, feed of animal origin mixing raise or adopt colza cake, soya-bean cake, groundnut cake, sesame-send cake, bean dregs artifical compound feed.
B 2, bait throwing in quantity: feed to be directly invested on waterline Chi Po on the upper side or at bank, pond erection food platform, fine, water quality is pure and fresh, and daily ration, feeding quantity increases; Weather is overcast and rainy, water quality deterioration, and daily ration, feeding quantity reduces, and Feeding time should be between the lights.
C 2, daily management: observe crab pond water quality and food residual state morning, according to water quality oxygenation timely, pull foreign material out; At dusk claire crab ingests situation, checks crab pond fence facility.
D 2, Water-quality control: June, the depth of water added to 1.5 meters, and water colour is light, and transparency is high, and pond water pH value, between 7-8.5, changes a Chi Shui or weekly or change water 1/4-1/3 in every 10 days 6-9 month crab each moon of pond.
E 2, pest control: protection against rodents equipment is set or discharges pharmaceutical chemistry, mouse cage in the outside of fence facility, in crab pond, drag for frog and tadpole, catch water snake, soft-shelled turtle.
(4), pond crab is fished for:
A 3, fishing time: between annual 10-11, carry out river crab fish for.
B 3, catching method: collection crab kerve is set before discharge outlet, drains Chi Shuihou and to reinject a small amount of new water, again drain and fish for, repeat 1-2 time.
In described step (1), crab Chi Sizhougeng adopts earth to arrange, and has the comparatively slow gradient, grass planting on slope.
In described step (1), in crab pond, discharge outlet and water filling port all adopt stainless (steel) wire shutoff.
The invention has the beneficial effects as follows: the present invention is without the need to professional equipment, and without breeding pollution, cultural technique standard criterion, Rational Stocking, fishes in good time, improves significantly, effectively raise the seed output and quality of finished product river crab relative to traditional culture of Chinese mitten crab technology.
