Description
Technical field
The invention belongs to aquatic products nursery fields, are related to a kind of method for culturing seedlings of Macrobrachium rosenbergii, and in particular to a kind of Roche
The cultural method of pond crayfish seedling.
Background technology
Aquatic products refer to animal and its converted products of ocean and fresh water fishery production.Fresh and living aquatic products, be divided into fish, shrimp,
Crab, four major class of shellfish.Aquaculture is the production activity of the lower breeding of artificial control, cultivation and harvest aquatic animals and plants, and aquatic products is supported
It is typically to raise the aquatic products seedling of purchase to certain size and sell to grow family.Aquatic products are needed in cultivation using prebiotic
Bacterium, vitamin etc. are to improve the resistance of aquatic products, harmful microbe in pool is inhibited to breed.Existing prebiotic promotor composition
After being spilled into pool, it is easy to cause the drastically decline of the transparency and finish of water body, this can influence the growth and development of aquatic products.
Invention content
The technical problem to be solved in the invention is a kind of training of the Macrobrachium rosenbergii seedling proposed in view of the above technical problems
The method of supporting.
In order to achieve the above objectives, the technical solution adopted in the present invention is：A kind of cultural method of Macrobrachium rosenbergii seedling, it
Include the following steps：
（a）The salinity for controlling water in nursery pond, the shrimp seedling young that strainer is fished for is transferred to wherein, and it is 8 ~ 120,000 to control density
Tail/m3；Fairy shrimp nauplius is fed, 4 ~ 8 h are fed once；It is rich feeding after the shrimp seedling larval culture 7 ~ 10 days
Increase before year worm nauplius and feeds egg custard；After the shrimp seedling larval culture 15 ~ 18 days, also increases and feed prawn slice；Good year
The feeding volume of worm nauplius, egg custard and prawn slice is subject to the shrimp seedling young 1h and is eaten up；The salinity of water in the nursery pond
Start to be 6 ~ 7 ‰, 4 ~ 5 ‰ are reduced to after cultivating 6 ~ 7 days, 2.5 ~ 3 ‰ are reduced to after cultivating 12 ~ 13 days, it is reduced to 1 after cultivating 18 ~ 19 days ~
2‰；
（b）It will emerge after the shrimp seedling larval culture 20 ~ 22 days；
Step（a）And step（b）In, water temperature is 31 ~ 32 DEG C in the nursery pond, and dissolved oxygen is 5.5 ~ 5.8mg/L.
Optimally, step（a）In, the strainer is 160 ~ 180 mesh.
Optimally, step（a）In, during only feeding fairy shrimp nauplius, also it is separately added into the dimension of 500 ~ 1000ppm
Raw element C and chitosan.
Since above-mentioned technical proposal is used, the present invention has following advantages compared with prior art：Macrobrachium rosenbergii of the present invention
The cultural method of seedling passes through the adjustment of the synchronous adjustment and bait for carrying out salinity in shrimp seedling young incubation, such energy
Enough improve the shrimp seedling young to the adaptation of fresh water can, to improve the survival rate of Macrobrachium rosenbergii；And cost can be reduced.
Specific implementation mode
The cultural method of Macrobrachium rosenbergii seedling of the present invention, it includes the following steps：（a）The salinity of water in nursery pond is controlled,
The shrimp seedling young that strainer is fished for is transferred to wherein, and it is 8 ~ 120,000 tails/m to control density3；Feed fairy shrimp nauplius, 4 ~ 8
H is fed once；After the shrimp seedling larval culture 7 ~ 10 days, increases before feeding fairy shrimp nauplius and feed egg custard；
After the shrimp seedling larval culture 15 ~ 18 days, also increases and feed prawn slice；Fairy shrimp nauplius, egg custard and prawn slice are fed
Amount is subject to the shrimp seedling young 1h and is eaten up；The salinity of water starts to be 6 ~ 7 ‰ in the nursery pond, it is reduced to 4 after cultivating 6 ~ 7 days ~
5 ‰, it is reduced to 2.5 ~ 3 ‰ after cultivating 12 ~ 13 days, 1 ~ 2 ‰ are reduced to after cultivating 18 ~ 19 days；（b）By the shrimp seedling larval culture 20 ~
It emerges after 22 days；Step（a）And step（b）In, water temperature is 31 ~ 32 DEG C in the nursery pond, and dissolved oxygen is 5.5 ~ 5.8mg/
L.Can improve in this way the shrimp seedling young to the adaptation of fresh water can, to improve the survival rate of Macrobrachium rosenbergii；And it can reduce
Cost.Step（a）In, the strainer is 160 ~ 180 mesh.Step（a）In, during only feeding fairy shrimp nauplius, also divide
Not Jia Ru 500 ~ 1000ppm vitamin C and chitosan.
The preferred embodiment of the invention will be described in detail below.
