Description
Technical field
The present invention relates to cultural technique fields, and in particular to a kind of river crab high-efficiency stepped formula pond breeding method.
Background technology
River crab original name Eriocheir sinensis is young crab before breeding migration, because of its shell colour cast Huang, is commonly called as " yellow crab ", property
Gland very little, does not develop substantially, and the weight of liver is far longer than gonad weight.It is just sent out after it completes last time and is casting off a skin
It educates for " green crab ", shell color ink is green, and gonad development is plentiful, and male crab foot of a chela villus silk fabric is close, and step bristle is slightly grown, and female crab abdomen covers completely
The headkerchief cuirass outside of belly, the bristle of abdomen border are long and close.The all one's life of river crab is after zoea, megalops larva, young crab and into crab
Etc. several stages, 5 huskings of the young is needed to become megalops larva in life, then become through 13-15 husking into crab, its all one's life is only
There are one the cyclostage, breeding end lives also just terminate, and in general, river crab feeding habits are very miscellaneous, under field conditions (factors) with drinking water
Based on grass, humus, addiction spoil, also eating spiral shell, freshwater mussel, worm, insect also prey on small fish, shrimp, food deprivation once in a while
When also can cannibalism.
The breeding way of river crab is gradually changed, and scale is increasing from naturally catching to artificial breeding at present.
During artificial breeding, it will usually which big using larger cultivation density, cooperation is sprayed insecticide and hormone, and uses concentrate feed
Or premix is fed so that the meat of river crab is poor, and in vivo containing more hormone, the mankind can also influence body after eating and be good for
Health, and the river crab death rate is higher, and survival rate is low, and the coefficient of condition of river crab does not often reach requirement, and the economic benefit is not high.
Invention content
(1) the technical issues of solving
In view of the deficiencies of the prior art, the present invention provides a kind of river crab high-efficiency stepped formula pond breeding method, using rank
Ladder type pond culture, raises that river crab cream fat thickness is greasy, and meat is rich delicious, high financial profit.
(2) technical solution
In order to achieve the above object, the present invention is achieved by the following technical programs：
A kind of river crab high-efficiency stepped formula pond breeding method, includes the following steps：
(1) staged pond is built：Select that water is sufficient, water quality is good, free of contamination pond is as aquaculture pond, aquaculture pond
Pond obstruct high 1.8-2m, pond stalk width 1-1.5m, slope ratio is 1:2-3, aquaculture pond are divided into phytal zone, buffering area and profundal zone, phase
Gentle slope, phytal zone depth of water 0.3-0.5m, buffering area depth of water 0.5-1.2m, profundal zone depth of water 1.2-2m, in shallow water are equipped between neighbour
Very aqueous water plant and floatability water plant are planted in area and buffering area, heavy aqueous water plant is planted in profundal zone；
(2) launched juvenile crab at the beginning of 3 months, throw-in density for 400-600 only/mu, before dispensing 20 days with the full pond of quicklime slurrying
It splashes, 10 days fertilising cultivation food organisms, apply farm manure 1000-2000kg, the food of juvenile crab 3-4% before dispensing per acre before dispensing
Disinfect with salt solution 3-5min, and spiral shell was launched at the beginning of 4 months, and spiral shell injected volume is 100-200kg/ mus；
(3) 7 points of every morning mid-April-August, at 15 points in afternoon, at night 21 points primary young crab respectively launched in phytal zone raise
Material, the juvenile crab feed include the constituent of following parts by weight：20-40 parts of fishbone dust, 10-20 parts of pig blood, albumen powder 20-
40 parts, 5-12 parts of dried silkworm chrysalis meal, 30-50 parts of wheat flour；
(4) August-October, 6 points of every morning, at 13 points in afternoon, at 17 points in afternoon, at 22 points in evening respectively launch once in phytal zone
Into crab feed, the constituent that following parts by weight are included into crab feed：10-15 parts of corn flour, perfect compound feed 20-
30 parts, 10-20 parts of small fish, 4-8 parts of eggshell；
(5) 10 the end of month, you can captured.
Preferably, very aqueous water plant described in step (1) is wild arrowhead, reed, wild rice stem bamboo shoot or cattail, and floatability water plant is
Floating heart or duckweed, aqueous water plant of sinking are hornwort, Egeria najas or waterweed.
Preferably, young crab specification is 100-200/kg in step (2).
Preferably, 100-120kg/ mus of quick lime usage amount in step (2).
Preferably, spiral shell is divided into 3 batches of additions in step (2), and every batch of is divided into 5-10d between launching.
Preferably, in step (3) and step (4), when night launches feed, river crab is attracted to assemble with blue-fluorescence.
(3) advantageous effect
The present invention provides a kind of river crab high-efficiency stepped formula pond breeding methods, have the advantages that：
Using staged pond breeding method, phytal zone can be used for feeding feed feeds by river crab, and profundal zone is suitble to river
Crab rests, and daily river crab moves back and forth, and can effectively consume its muscle power, prevent from escaping and fight at close quarters mutually, and movement can make
The sexual gland of river crab is more flourishing, and cream fat thickness is greasy, more delicious, nutritive value also higher；Different stages of growth provide not of the same race
The feed of class and proportioning, animal fodder and plant feed proportioning are reasonable in feed, without using hormone and pesticide, improve river
The constitution and survival rate of crab improve the meat of river crab.
