Description

A kind of bionic aquatic weed
Technical field
The present invention relates to artificial culture's device of a kind of Macrobrachium nipponensis, be specifically related to a kind of artificial veil bionic aquatic weed that can improve Macrobrachium nipponensis incubation rate.
Background technology
Macrobrachium nipponensis (Macrobrachiumnipponense) is under the jurisdiction of Crustachia, Decapoda, Palaemonidae, macrobrachium genus, have another name called Macrobrachium nipponensis(de Haan), it is commonly called as astacus, for the edible shrimp of fresh water that China is important, its meat flavour is delicious, fried astacus is dish extensively popular together, and therefore the market demand of astacus is very big, and economic worth is high.But, due to the problem such as water pollution, overfishing in recent years, the wild resource of Macrobrachium nipponensis being caused heavy damage, protection Macrobrachium nipponensis(de Haan) wild resource is brought into schedule.Traditional Man cultivation Macrobrachium nipponensis obtains the production model of shrimp Seedling: employing is fished for wild shrimp with ovums and put into Tu Chi breeding, the shrimp Seedling survived by final struggle for existence is for producing, so Macrobrachium nipponensis(de Haan) wild resource can be done a lot of damage, and the dependency of wild resource is very big.It addition, the stocking density that the internecine characteristic of Macrobrachium nipponensis also results in its artificial breeding's density shrimps more economic than other is much lower, it is impossible to form the yield that unit of water body is stable.Macrobrachium nipponensis faces miniaturization, plants the problems such as matter degeneration, scarcity of resources.For this, in succession carried out Macrobrachium nipponensis artificial propagation, cultivation etc. and attempted.But, due to the characteristic that cuts one another's throats of Macrobrachium nipponensis, no matter the links such as supporting temporarily after nursery, commercial sized prawn are fished for, transport, sale, all very easily mutually injures and causes death.Shrimp seed rearing is difficult, and cultivation density is low, and specific yield is low, and market supply is unstable, causes that Macrobrachium nipponensis cultivation difficulty is big, it is difficult to promote.
Macrobrachium nipponensis parent shrimp is during mating, need to wait that after female shrimp shell, newly unhardened front 2 hours of shell could with male shrimp copulation, if now lacking suitable veil (blindage), the female shrimp of soft shell can be eaten up by other female shrimps, and the loss of parent shrimp is apparent from.Additionally, just the zoea of 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 breeding pond, in producing in the past, often throw in the on-aquatic plant blindage such as branch of terrestrial, can along with rotten pollution degradation water quality;The blindages such as queen closer, tile, stone whetstone are thrown in breeding pond, water body volume is taken excessive, the bottoms such as the effective shed space formed 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 also very low to the space availability ratio of water body.
Macrobrachium nipponensis belongs to the end and dwells shrimps, it is necessary to veil is perched for it and hides harmful animal, simultaneously, it is also desirable to the hapalonychia state of veil protection degenerate cllipticity phase exempts from similar attack.When adopting pool nursery, also there is the mode adopting plantation pasture and water in pool to providing veil for it, if needing adopt plantation pasture and water and reach the mode of stable density, in addition it is also necessary to pasture and water energy stable existence a period of time, be extremely difficult in practical operation in the past.Its main difficulty has: first, and by the restriction of pasture and water kind, the intensity of different pasture and water kind Photosynthetic photographs is different with photoperiod demand, the concentration of fertilizer in water is required also different, requires to there is also difference to the depth of water.Therefore, individually cultivate in actual production or nixed planting is all difficult to obtain desirable pasture and water density, the management of plantation pasture and water also can increase many troubles.It addition, continual regularly to check and to keep certain pasture and water density in Macrobrachium nipponensis idiophase, add the workload of the personnel of breeding.Second, owing to Macrobrachium nipponensis has two breeding seasons in 1 year the 4-9 month, wherein the 6-7 month is the Sheng phase, if adopting the mode of plantation pasture and water to provide veil for it, being difficult to find one not have biotic intrusion and growing way to be exceedingly fast, short-term can reach the pasture and water of suitable density and do veil.Find in producing in the past, some area is primary, growing way advantage pasture and water faster (the red heart grass such as Weishan Lake) are solid in wheat harvest time maturation when Macrobrachium nipponensis breeds the busy season, easy occurrence of large-area is withered, as selected these type of pasture and water to do the veil of Macrobrachium nipponensis(de Haan) breeding, more undesirable.For Macrobrachium nipponensis artificial breeding, it is necessary to a kind of novel veil (blindage), can be used not only for the cultivation of pond shrimp Seedling, it is also possible to be applied to other and cultivate in containers, for instance: aquarium, and need that it is stable, easy cleaning, can recycle.
Existence due to drawbacks described above, cause that the seed of conventional Macrobrachium nipponensis breeding success rate relatively low, production and application always is mainly by the mode consuming Macrobrachium nipponensis wild resource, the method yields poorly down, causes the wasting of resources, is difficult to stably bring out shrimp Seedling superior in quality, uniform specification.
