Abstract
A propagation control method for indoor cultivation of Perinereis aibuhitensis is characterized by including the sequential steps of 1, preparing a breeding cement pool; 2, selecting parents of Perinereis aibuhitensis; thirdly, managing ways of breeding outside cages and breeding density; 4, inhibiting propagation of heteronereis; 5, controlling great propagation of heteronereis; 6, performing artificial and natural insemination; and 7, selecting hatching conditions, namely controlling the water temperature at 25 DEG C, hatching to obtain three-setiger juvenile in three days, and cultivating the juvenile. The method has the advantages that a great amount of parents of Perinereis aibuhitensis can be controlled to propagate simultaneously, and juvenile cultivation is arranged designedly; the method is performed in indoor cement ponds and insusceptible to seasons and tides.
Description
Technical field
The present invention relates to the propagation method of a kind of clam worm, be specifically related to a kind of regulate and control method of indoor culture perinereis aibihitensis Grube breeding.
Background technology
Perinereis aibihitensis Grube (Perinereis aibuhitensis) belongs to Annelida, polychaeta, Nereidae, happiness is lived in caves in calm, nutritious silt particle beach, intertidal zone, the sociales of silt beach, China intertidal zone biology, also the main composition that is CHINESE OFFSHORE bottom community is biological, has the important ecological value.
Clam worm is the high-quality bait of fish, shrimp, crab etc., and nutritive value is abundant, is called as " omnipotent bait ", has high economic worth.The C.I.F. of Japanese market is per ton up to tens thousand of dollars at present, and very worthy equally in market, West Europe, supply falls short of demand.
Perinereis aibihitensis Grube has the features such as individuality is large, protein content high (70%-80%), is the important kind that can develop in Nereidae animal, has wide development prospect.In recent years, domestic existing many enterprises and institute have carried out the cultural technique research of perinereis aibihitensis Grube in succession.At present, seed rearing depends on the colony of physical maturity in a large number, in particular season, fishes for natural heteronereis and breeds, seasonal strong, and is subject to morning and evening tides control, and uncontrollable strong, for arranging production, carrying out on a large scale, seed rearing is unfavorable.
At present the propagation method of general perinereis aibihitensis Grube, fishes for heteronereis ripe in natural water area exactly, has strong seasonality, for the artificial breeding work of perinereis aibihitensis Grube, brings a lot of inconvenience.Be unfavorable for that large area is concentrated hatching, cloth ovum, the carrying out of the follow-up work such as grow seedlings, greatly limited perinereis aibihitensis Grube manual and bred carrying out of scale.Separately, current propagation method, the present invention aims to provide the sexual maturity of a kind of indoor culture perinereis aibihitensis Grube and artificial regulatory propagation method.
Summary of the invention
The object of the invention is for heteronereis quantity in prior art few, poor synchronization, and the deficiencies such as insemination rate is lower, provide a kind of and can guarantee that heteronereis quantity is many, synchronism is high, and can be according to the regulate and control method of producing the indoor culture perinereis aibihitensis Grube breeding that regulates heteronereis maturation and repoductive time.
The object of the invention is to realize by following technological means: a kind of regulate and control method of indoor culture perinereis aibihitensis Grube breeding, is characterized in that the method sequentially comprises the steps:
1) store up the preparation of cement pit: cement pit is the strip pond (8m * 5m * 1m) of 40 cubic metres of water bodys, add in outdoor native pond, cultivated perinereis aibihitensis Grube silt as substrate, thickness is more than 30cm, one jiao of tool osculum of cement pit, stores up front with more than filtering sea immersion 48h;
2) selecting of close silkworm: select the clam worm adult that physique is big and fleshy, color and luster is ruddy, health is anosis, individual specification is 15-25cm, and average weight is more than 3g/ bar;
3) put mode in a suitable place to breed and store up the management of density: clam worm 50-75kg is stored up in every pond, minute within three days, dropping into close silkworm, normally entering every day after draining, according to every pond earth surfaces clam worm, being no more than 20 and determining the saturation state of the close silkworm in pond for standard; According to Various Seasonal, carry out respectively daily management;
4) suppress the method for heteronereis breeding: in summer, can find that ripe heteronereis floats on the water surface after water inlet June, when not needing to produce, rapidly water be drained, more than waiting for 1h, only cross the about 15min of water; After this, only cross water once every day, and the time, in 15min, makes that cement pit is capable does not become the water surface;
5) the prolific method of regulation and control heteronereis: while needing a large amount of close silkworm breeding, recover water inlet, maintain water body 30cm, the heteronereis moving about in 1h is that maturity is individual preferably, with dredger, fishes for, and puts into clam worm dish, thin sponge shop fixtures, for water suction, reach after need of production quantity, carry out rapidly artificial breeding;
6) artificial nature's method of inseminating: rinse with fresh water after the earth on close silkworm surface, selecting male and female is positioned over respectively in different vessels, the male and female of take are than carrying out artificial natural insemination as 3:1, be about to close silkworm and put into the floatable vegetables plastic crate that leaks (diameter 40cm) simultaneously, density is no more than 100 close silkworms and is advisable;
7) incubation condition: clam worm egg laying amount is large, after 3h, most of close silkworm has completed after breeding, with 300 mesh sieve thin,tough silk, collects after fertilized egg, puts into the cone tank hatching of 1t left and right, and hatching density is about 10/ml; Water temperature is controlled at 25 degree, and after 3 days, hatching is three just joint nectocaetes, after carry out seed rearing.
A regulate and control method for indoor culture perinereis aibihitensis Grube breeding, is characterized in that, the daily management in described step 3) comprises: noon every day is entered nature seawater over more than earth 30cm in close silkworm pond, stops into water, maintains behind 2h left and right, drains seawater; According to the situation of ingesting, about 2h after draining water, at dusk common shrimp bait 0.5-1kg throws something and feeds in each pond;
Daily management in winter is: do not carry out warm light regulation and control winter, when natural temperature reaches 0 ℃ of left and right, adds the above seawater of 30cm and passes the winter; To March in spring, recover normal daily management.
Compared with prior art the present invention has following obvious advantage: 1, the present invention regulates and controls a large amount of close silkworms and synchronously breeds, can be in a planned way by row's production of growing seedlings; 2, the present invention carries out at indoor cement pit, not limited by season and morning and evening tides; 3, the present invention, by Artificial Control mode, selects the good heteronereis of maturity and produces, and fertilization rate and incubation rate are high; 4, the artificial nature of the present invention method of inseminating, comprises and uses normal female-male proportion, make clam worm egg laying amount large, fertilization rate and incubation rate are high; 5, the present invention is suitable for perinereis aibihitensis Grube seed industrialization production.
