A kind of bionic aquatic weed

Technical field

This utility model relates to artificial culture's device of a kind of Macrobrachium nipponensis, and being specifically related to one can improve day The artificial veil bionic aquatic weed of this macrobrachium incubation rate.

Background technology

Macrobrachium nipponensis (Macrobrachium nipponense) be under the jurisdiction of Crustachia, Decapoda, Palaemonidae, Macrobrachium belongs to, and has another name called Macrobrachium nipponensis(de Haan), is commonly called as astacus, and the fresh water important for China eats shrimp, and its meat flavour is delicious, fried river Shrimp is the most popular dish, and therefore the market demand of astacus is very big, and economic worth is high.So And, due to the problem such as water pollution, overfishing in recent years, the wild resource of Macrobrachium nipponensis is caused sternly Heavily destroying, protection Macrobrachium nipponensis(de Haan) wild resource is brought into schedule.Traditional Man cultivation Macrobrachium nipponensis obtains the life of shrimp Seedling Product pattern is: employing is fished for wild shrimp with ovums and put into Tu Chi breeding, the shrimp Seedling survived by final struggle for existence For producing, so Macrobrachium nipponensis(de Haan) wild resource can be done a lot of damage, and to the dependency of wild resource very Greatly.It addition, the internecine characteristic of Macrobrachium nipponensis also results in its artificial breeding's density than other economic shrimps The stocking density of class is much lower, it is impossible to form the yield that unit of water body is stable.Macrobrachium nipponensis face miniaturization, Plant the problems such as matter degeneration, scarcity of resources.Taste to this end, in succession carried out Macrobrachium nipponensis artificial propagation, cultivation etc. Examination.But, due to the characteristic that cuts one another's throats of Macrobrachium nipponensis, no matter supporting temporarily after nursery, commercial sized prawn are fished for, The links such as transport, sale, the most mutually injury cause death.Shrimp seed rearing is difficult, and cultivation density is low, Specific yield is low, and market supply is unstable, causes Macrobrachium nipponensis cultivation difficulty big, it is difficult to promote.

Macrobrachium nipponensis parent shrimp during mating, unhardened first about 2 hours of new shell after needing to wait female shrimp shell Could be with male shrimp copulation, if now lacking suitable veil (blindage), the female shrimp of soft shell can be by other female shrimps Eating up, the loss to parent shrimp is apparent from.It addition, the zoea of just birth needs a large amount of veils Hide and perch, one of enough veil also key being successfully nursery can be provided for it, but in the past Production is often thrown in breeding pond the on-aquatic plant blindage such as branch of terrestrial, can be along with rotten degraded dirt Dye water quality；Throw in the blindages such as queen closer, tile, stone whetstone to breeding pond, water body volume is taken excessive, shape The bottoms such as the effective shed space become is very limited and is only capable of in pool produce space, the easy anoxia of pool bottom aquifer, Meeting the rainy day can cause the hypoxia death of shrimp, and traditional method is the lowest to the space availability ratio of water body.
