Specific embodiment
The present invention will be further explained with reference to the accompanying drawing.
A kind of breeding and propagation method and device thereof of Australia freshwater lobster as shown in attached drawing 1 to 7, farming site select water
Source is good, and irrigation and drainage are convenient, and air is fresh, environment quiet, the canal not used by the place of nature and human interference, breeding water
Water is promoted with elevator pump to after aeration biochemical processing pond after qualified through water quality detection after sedimentation basin precipitates, then through Protein Separation
Enter ultraviolet radiation for sterilizing and disinfecting after device, then after being heated to 28 DEG C to steam heating bath, oxygen after being sent to sand filter with pressure pump
Cone enters back into water inlet line into shrimp aquaculture pond 1 of getting married.Using microcirculation flowing water form, flow is in every 16 hours close shrimp
The water of aquaculture pond filters one time, and wherein aeration tank is used to decompose the organic pollutant in water, and protein separator can adsorb mixed
The organic matter of miscellaneous various granular dirts and solubility in water, treated culture water quality of tank system is pure and fresh, dissolved oxygen amount
Height, especially during reinforced cultivating, the dissolved oxygen amount of breeding water be should be ensured that in 4mg/L, and good aquatic environment can be improved
Female shrimp survival rate and egg laying rate of red swamp.
Selecting parent shrimps are energetic, appendage is complete, body is smooth, without attachment and disease (as tail portion is rotted and shell is impaired)
Make close shrimp at shrimp.In order to obtain higher reproductive capacity, select individual weight in 120g, maturity is good, has larger fecundity
Close shrimp additionally presses specification size packets, female male parent shrimp similar in selection individual, weight.Before entering wintering pond, it is necessary to use
Concentration is formalin dipping bath 5 minutes or so of 200 × 10-6, after eliminating aufwuch, could move into close shrimp ponds cultivation.According to
Production experience, female-male proportion are more appropriate with 2.5: 1.Breeding density with every square metre put in a suitable place to breed 10-12 it is more appropriate,
The density put in a suitable place to breed is directly related to the cultivate effect of close shrimp, and breeding density is excessive, then leads to close shrimp retarded growth；It puts in a suitable place to breed close
Degree is too small, and it will cause the wastes of pond, manpower and material resources.
Early November parent shrimp enters close shrimp aquaculture pond, and the shrimp crab particle for feeding Commercial protein content 40% at dusk daily is raised
Material, during heating up reinforced cultivating, increase feeds the animal fodders such as some fishes, shrimp, and feeding volume is generally close shrimp weight
1%, and depending on its eat food situation increase or decrease.Residual bait, excrement timing are sopped up, in order to avoid water quality deterioration.In During Overwintering Period
Timing is oxygenated, uninterrupted to be oxygenated during strengthening management.When reinforced cultivating heats up, temperature is controlled between 27~29 DEG C, battalion
Feeding substance is the material base of close shrimp gonad development, in the nurturing period, increases especially during reinforced cultivating and feeds small fish, earthworm
The animal feeds such as earthworm and shell, can more promote its growth and development.
Sewage disposal device, close shrimp aquaculture pond 1 and shrimp seedling collection device 2 are sequentially connected, wherein parent's shrimp aquaculture pond 1 is divided
For close shrimp mobile layer 101 and shrimp seedling mobile layer 102, several shrimp nests 103 are provided on the side wall of the parent shrimp mobile layer 101,
The parent shrimp mobile layer 101 is set to 102 top of shrimp seedling mobile layer, and is separated by hollow out net 104.Hollow out net 104 is by close shrimp
It is split with shrimp seedling, effectively avoids close shrimp pincers food shrimp seedling, ensure that the higher survival rate of shrimp seedling.
The bottom of the shrimp seedling mobile layer 102 is provided with overflow port, and the overflow port is arranged with overflow pipe 105, described to overflow
The top of flow tube 105 extends the top of close relative shrimp mobile layer 101, and the shrimp seedling mobile layer 102 is collected by overflow port and shrimp seedling
Device 102 connects.When the water surface elevation in close shrimp aquaculture pond 1 is higher than 105 top of overflow pipe, extra water can pass through overflow pipe
105 drain, and poroid plate 106 is covered in the top of overflow pipe 105, can prevent close shrimp from escaping via overflow pipe 105, when needing to receive
When collecting shrimp seedling, overflow pipe 105 is pulled up upwards, shrimp seedling follows water flow to enter shrimp seedling collection device 2 by overflow port, discharges into shrimp seedling
Moisture in collection device 2 can complete the collection of shrimp seedling.In order to save space, and also to which shrimp seedling is facilitated to follow water flow
Into shrimp seedling collection device 2, the shrimp seedling collection device 2 is set to the bottom in close shrimp aquaculture pond 1, the shrimp seedling is collected
Device 2 includes shrimp seedling collecting pit 201, and the opening of the shrimp seedling collecting pit 201 covers hollowed-out board 202, to facilitate observation shrimp seedling
Inside collecting pit.
The shrimp nest 103 is divided for the first shrimp nest 107, the second shrimp nest 108 and third shrimp nest 109, and by the first shrimp nest
107 are arranged in the lower section of the second shrimp nest 108, and the third shrimp nest 109 is set to the lower section of the second shrimp nest 108, first shrimp
Nest 107, the second shrimp nest 108 and about 109 third shrimp nest successively interlock, in case the superposition of about 103 each shrimp nest is formed and is blocked, shadow
The illumination of shrimp nest 103 is rung, the first shrimp nest 107 and the second shrimp nest 108 are tubular, simultaneously because the first shrimp nest 107 and third shrimp
Nest 109 is located at water surface lower position, and in order to avoid its illumination deficiency, the first shrimp nest 107 and third shrimp nest 109 are provided with
Hollow hole, the first shrimp nest 107 can promote water quality to flow, and guarantee that the aquatic environment in the first shrimp nest 107, figure are biggish
Close shrimp inconvenient activity, it is difficult to dissociate to the shrimp nest on upper layer, therefore be placed on the outer wall convex at 109 middle part of the lowermost third shrimp nest
It rises and forms spherical shape to cooperate biggish close shrimp figure, facilitate its oogenesis, and third shrimp nest 109 is placed in the bottom of close shrimp mobile layer 101
End, and close to hollow out net 104, water flow is relatively slow, the main part of third shrimp nest 109 is designed as spherical shape, close shrimp is in third shrimp nest
The excreta generated in 109 can globally slide past the hollow hole on 109 outer wall of third shrimp nest and exclude to ensure that other than shrimp nest
Health in shrimp nest.
Due to being provided with hollow hole on the outer wall of first shrimp nest 107 and third shrimp nest 109, structure is simultaneously insecure, especially
To be outer end larger by water impact or close shrimp clamp is than more serious, it is damaged in order to prevent, in the first shrimp nest 107 and third shrimp
The outer end of nest 109 is arranged with fixed ring 110.
In the present embodiment, on November 6th, 2017, it has been put into female shrimp 7310 altogether in 34 close shrimp aquaculture ponds 1, it is male
Shrimp has been put into 2924 altogether, slowly heats up after three days, and by between later 27~29 DEG C of temperature control key, close shrimp is December 6
Day starts oogenesis, until on 2 6th, 2018 survive female shrimp totally 5988 tail, having the female 5896 tail egg laying rate of red swamp of shrimp of oogenesis is 98.5%, female shrimp
Survival rate 81.9%.
The above is only a preferred embodiment of the present invention, it should be pointed out that: for the ordinary skill people of the art
For member, various improvements and modifications may be made without departing from the principle of the present invention, these improvements and modifications are also answered
It is considered as protection scope of the present invention.
