Description
Technical field
The present invention relates to a kind of freshwater shrimp indoor raising of seedling mixing bait-throwing method, belong to aquaculture field.
Background technology
Freshwater shrimp, also known as river prawn, scientific name Macrobrachium nipponensis (Macrobrachium nipponense), category shell-fish, Decapoda,
Swimming suborder, Eucyphidea, long-armed section, pond crayfish category, are a kind of Main economic shrimps for being distributed widely in freshwater.Freshwater shrimp nutrition
Value is abundant, and fine and tender taste delicious flavour is a kind of rare aquatic products being loved by people.But the natural yield of freshwater shrimp has
Limit, seed supply is difficult to the need for meeting production cultivation, the change mainly due to freshwater shrimp in the larval metamorphosis stage to environmental condition
Change very sensitive, row third time is much dead when casting off a skin particularly after hatching, the agreeable to the taste feed and feeding habits of this and the young change
Relevant, the research to freshwater shrimp paedomorphosis stage bait and its feeding method just turns into the important pass of raising freshwater shrimp young survival rate
Key.

The beneficial effect of invention
The freshwater shrimp indoor raising of seedling mixing feeding method of the present invention, according to different need of the freshwater shrimp paedomorphosis stage to bait
Ask, Reasonable adjustment food species and feeding volume, both can be just hatching by being inoculated with unicellular alga in freshwater shrimp mesoderm growing early stage
The freshwater shrimp young of membrane provides open-mouthed bait, and inorganic elements waste in water body can be absorbed again, can also be carried for follow-up wheel animalcule
For part bait；Freshwater shrimp juvenile stage mainly feeds the bait of high protein content；The death rate highest II- during paedomorphosis
V stages phase, reasonably combined bait feeding species, supplement wheel animalcule and increase feeding volume, so as to reduce what the freshwater shrimp young killed and devour mutually
Several meetings, improve young survival rate, promote the young to be rapidly completed metamorphosis process；In the young shrimp stage, minced fillet etc. is fed by supplement fresh
Living bait, accelerates the shrimp seedling speed of growth and significantly improves survival rate.In the present inventive method carry out freshwater shrimp seed rearing, the young into
Motility rate is high, emergence rate is stable, shrimp seedling vigor is good, under water temperature 24-27 degrees celsius, by the cultivation of 30 days or so time,
Per cubic meter of water produces the tails of shrimp seedling 2-4 ten thousand.Using nursery feeding method provided by the present invention, young survival rate can reach
28-35%, and it is generally conventional 10% or so.
