Abstract
The present invention relates to a kind of Eriocheir sinensis ovigerous crab indoor culture methods, comprising: (1) buys the female crab and male crab of Eriocheir sinensis mating period, mate oogenesis after being stimulated with seawater, forms ovigerous crab；(2) first by circular glass steel water tank soaking disinfection, then brackish water is injected in sink；(3) ovigerous crab in step (1) is put into above-mentioned sink, keeps circulating for breeding water body, fed daily during cultivation and hang razor clam 3-5 only, surplus residual bait is eaten in removing every morning and soil pick-up changes water.Aquaculture management is carried out to Eriocheir sinensis ovigerous crab through the invention, ovigerous crab survival rate reaches 95% or more, and has normally hatched zoea, has a good application prospect.
Description
Technical field
The invention belongs to aquaculture field, in particular to a kind of Eriocheir sinensis ovigerous crab indoor culture method.
Background technique
Eriocheir sinensis is commonly called as river crab, steamed crab etc., breeds in growth, river mouth or shallow sea in fresh water.Eriocheir sinensis
It is favored by people because of its delicious flavour, is the traditional famous-particular-excellent aquatic products treasure in China, is occupied in China's culture fishery
Important economic status.In the natural environment, annual autumn and winter, the Eriocheir sinensis of the Yangtze river basin is to river mouth migration, at this
In complete mating oogenesis, hatchling.In recent years, it is influenced due to river mouth by environmental pollution, hydraulic engineering construction etc., Eriocheir sinensia
The yield of the natural juvenile crab of crab plays pendulum, it is therefore desirable to carry out the research of Eriocheir sinensis artificial breeding.Eriocheir sinensis
Fertilized eggs usually develop hatching all on parent abdomen appendage, therefore, must carry out essence to it in the breeding process of ovigerous crab
Thin management, scientific regulating water quality promote its normal development.In addition, routine observation is needed to embrace in actual production or scientific research
Ovum crab embryonic development situation obtains different times embryo and is used as research material etc., therefore, establishes a kind of Eriocheir sinensis ovigerous crab
Indoor culture method, this is all of great significance for seed rearing and scientific research.
Summary of the invention
Technical problem to be solved by the invention is to provide a kind of Eriocheir sinensis ovigerous crab indoor culture methods, by this
Method carries out aquaculture management to Eriocheir sinensis ovigerous crab, and ovigerous crab survival rate reaches 95% or more, and has normally hatched flea shape
The young has a good application prospect.
The present invention provides a kind of Eriocheir sinensis ovigerous crab indoor culture methods, comprising:
(1) the female crab and male crab for buying Eriocheir sinensis mating period are embraced with mating after the seawater stimulation of salinity 18~19
Ovum forms ovigerous crab；
It (2), then will be in the brackish water injection sink of salinity 18~19 first by circular glass steel water tank soaking disinfection；
(3) ovigerous crab in step (1) is put into above-mentioned sink, keeps dissolved oxygen 7.0mg/L or more in water body, keep supporting
Circulating for water body to be grown, is fed daily during cultivation and hangs razor clam 3-5 only, surplus residual bait is eaten in removing every morning and soil pick-up changes water,
?.
Soaking disinfection in the step (2) uses concentration for the liquor potassic permanganate of 5ppm, and soaking time is 12~16
Hour, the immersion depth of water is 50~60cm.
The brackish water of salinity 18~19 in the step (2) using bittern and by filtering aeration after fresh water prepare and
At.
The depth of water of brackish water in the step (2) is 30~40cm.
Circulating for breeding water body is kept by the way that circulation filter is arranged above sink in the step (2).
The metallic support of several hollow outs is placed in the bottom of circular glass steel water tank, provides the hidden field inhabited to ovigerous crab
Institute.
The water source for changing water in the step (3) is the brackish water of salinity 18~19 after aeration, and quantity of exchanged water is raw water body
1/3。
The present invention relates to the specific methods of Eriocheir sinensis ovigerous crab cultivating and managing.Eriocheir sinensis ovigerous crab breeding process
In, it is longer from oogenesis to the hatchling time, 40-60 days or so are needed at normal temperature, and water condition, bait are needed in cultivation
Ask, habitat etc. has higher requirement, if cultivating condition is not suitable for, will lead to embryo and fall off and flow from parent
It produces, therefore the cultivating and managing of Eriocheir sinensis ovigerous crab is most important to the hatching rate for improving the young.
Beneficial effect
Aquaculture management is carried out to Eriocheir sinensis ovigerous crab through the invention, ovigerous crab survival rate reaches 95% or more, and
Zoea normally has been hatched, has been had a good application prospect.
Specific embodiment
Present invention will be further explained below with reference to specific examples.It should be understood that these embodiments are merely to illustrate the present invention
Rather than it limits the scope of the invention.In addition, it should also be understood that, after reading the content taught by the present invention, those skilled in the art
Member can make various changes or modifications the present invention, and such equivalent forms equally fall within the application the appended claims and limited
Range.
Embodiment 1
The female crab and male crab for buying Eriocheir sinensis mating period are formed with the oogenesis that mates after the stimulation of the seawater of salinity 18
Ovigerous crab.
By ovigerous crab cultivation in the circular glass reinforced plastic sink in laboratory, sink diameter 1m, high 80cm.Size can be according to reality
Border needs to be adjusted.It is put into before ovigerous crab and first impregnates sink 12h with the liquor potassic permanganate of 5ppm, impregnate depth of water 50cm, leaching
Again with the tap water service sink bottom filtered after being aerated and pool wall 3 times after the completion of bubble.With bittern and the fresh water after filtering aeration
It is configured to the brackish water of salinity 18, by the brackish water injection circular glass steel water tank of salinity 18, keeps depth of water 30cm.
Ovigerous crab is put into sink, 3-5 is put in each sink only, quantity can be adjusted according to sink size.In water
The different locations such as body middle part, bottom place 4-5 pneumatic head, and the quantity of pneumatic head can be adjusted according to glass reinforced plastic sink size
It is whole, keep dissolved oxygen 7.0mg/L or more in water body.A circulation filter is placed in the top of circular channels, keeps cultivation water
Body circulates.Filter cloth in daily cleaning replacement circulation filter, keeps the cleaning of filter cloth.Every morning during cultivation
9 points feed and hang razor clam 3-5 only, are adjusted in right amount according to the quantity of ovigerous crab, and the next morning, which removes, eats surplus residual bait and soil pick-up changes water,
Changed water source is the brackish water of salinity 18 after aeration, and quantity of exchanged water is the 1/3 of raw water body.Several engrave is placed in the bottom of circular channels
Empty metallic support, provides the hidden place inhabited to ovigerous crab.
Aquaculture management is carried out to ovigerous crab using above method, ovigerous crab survival rate reaches 95% or more, and normally hatches
Zoea.
