Description
Technical field
It is more particularly to a kind of that freshwater shrimp parent is reused the invention belongs to technical field of aquaculture, will be same
Cultivate in the special pond of the young that one time period hatched, it is ensured that the synchronism that shrimp seedling is grown, cultivate the high-quality shrimp seedling of neat specification,
The method for reducing freshwater shrimp parent's nursery of the water quality management cost of nursery pond in freshwater shrimp seed reproductive process.
Background technology
Freshwater shrimp (Macrobrachium nipponense), scientific name Macrobrachium nipponensis is the important economic freshwater shrimps of China.
Freshwater shrimp has the advantages that nutritious, fine and tender taste, delicious flavour.Increase due to people to freshwater shrimp demand, and freshwater shrimp is supported
Grow low cost, income is fast, the advantage such as profit is high has expedited the emergence of the development of shrimp culture industry.
The female shrimp of freshwater shrimp has oogenesis habit, after the ovum output of female shrimp, currently batch ovum also in hatching, the sexual gland of shrimp with ovums
Development is continued to, batch egg hatching terminates before treating, every 2~5 days, its sexual gland was just ripe again, carry out reproduction shell, mate and oviposit,
Carry out second hatching.Under conditions of water temperature, illumination, bait abundance, female shrimp is in breeding period（5~July）2~3 can be hatched
It is secondary.The egg load of female shrimp is long with body, body weight is proportionate：Breeding period（5~July）Single shrimp body first egg load be 1000~
1500/tail, second egg load can reach 2000~4000/tail, thus use carries out second nursery with a collection of parent,
Only need the half of nursery parent quantity first even less.The embryonic development of freshwater shrimp is accelerated with the rising of water temperature：From embryonated egg
Hatched to the young, in the case of 19.5~24.5 DEG C of water temperature, 21~23 days need to be lasted, and in the case of 25~28 DEG C of water temperature, only
Need 14~15 days.

The density of mu, it is disposable to deliver freshwater shrimp parent；By parent's reinforced cultivating stage, the cultivation of shrimp seedling is carried out in 5~July, at the beginning of 7 months
Put in a suitable place to breed in point pond for proceeding by shrimp seedling.During whole seed breeding：Freshwater shrimp parent can carry out 2 in same nursery pond~
3 hatchings, because the yield of the habit that pond capacity and freshwater shrimp are killed each other, thus shrimp seedling unit area will not be with hatching children
Body quantity increases and rises, and front and rear shrimp seedling twice is grown asynchronous, causes shrimp seedling specification irregular, difference in size
It is excessive.It is the bait for ensureing that shrimp seedling is sufficient, nursery pond water quality can always maintain fertile degree higher between at the beginning of April first arrival 7 months,
As feeding for shrimp seedling feed is accumulated for a long time with various metabolins in nursery pond, body eutrophication can be caused, it is serious
The general pool in seedling pond can occur, cause damage.Thus the stabilization that more ecological agent maintains water quality need to be put into the nursery later stage.
