Abstract
An artificial ovum picking-up method of red delavay morina root, characterized in that first of all red delavay morina roots weighed 400-800g are screened as father ones and are saved and raised, the keeping water temperature is 12-13DEG C, when the gonad index of the father red delavay morina roots grows to 10-20%, the diameter of their ovum achieves 190-200 mum, artificially inducting oviposit is started, first the father red delavay morina roots is dried in the shade for 1-1.5h and water flow for 0.5-1h, and then the water temperature is increased for 4-5DEG C for warming inducting and ovum is picked at dusk. Using this invention large quantity and high quality red delavay morina root ovum can be got and the larvae survival rate is high.
Description
Technical field
The present invention relates to a kind of method of red stichopus japonicus artificial spawning.
Background technology
The so-called sea cucumber of stichopus japonicus (Stichopus japonicus), in classification, be under the jurisdiction of Echinodermata (Echinodermata), Holothuroidea (Holothuroidea), Parapet hand order (Aspidochirota), Stichopodidae (Stichopodidae), mainly be distributed in the coastal state such as Liaoning, Shandong, Hebei of China, the Korea peninsula, Japan and the Russian Far East are coastal.Stichopus japonicus is traditional famous and precious precious marine product, breed scale expansion the coastal stichopus japonicus of northern China is very fast in recent years, 2004 are only Shandong Province's bright ginseng output just up to 5.7 ten thousand tons, and the output value is above 7,000,000,000 yuan, have formed aquaculture industry with local characteristic and new marine economy growth point.
In Japan, natural stichopus japonicus exists red stichopus japonicus, black stichopus japonicus and 3 strains of blue or green stichopus japonicus.Red stichopus japonicus mainly inhabits cay, the gravel area in foreign country, and blue or green stichopus japonicus and black stichopus japonicus are mainly seen at the bottom of the sand mud of inner bay.The red stichopus japonicus human body is thicker, and the market price is 2～3 times of blue or green, black stichopus japonicus.In view of the high economic worth of red stichopus japonicus, red thorn participates in introduces China from Japan in May, 2004.Because there are bigger difference in hydrology characteristics that Japan is coastal and northern China, how to carry out ovum artificial collection and become the bottleneck technology that red stichopus japonicus is grown seedlings on a large scale and cultures in China, the utmost point need solve.
Summary of the invention
The method that the purpose of this invention is to provide a kind of red stichopus ovum artificial collection, it can satisfy the demand of prior art.
A kind of method of red stichopus ovum artificial collection, the red stichopus japonicus that it is characterized in that at first screening body weight 400-800 gram carries out parent participation and stores up as parent participation, and the water temperature of storing up is 12～13 ℃, parent participation sexual gland index is grown to 10-20%, when ovum directly reached 190～200 μ m, the beginning artificial spawning was induced, after the 1-1.5h that dries in the shade is earlier induced in parent participation, flowing water 0.5-1h, water temperature is raise 4～5 ℃, heat up and induce, adopt ovum between the lights.
The present invention can obtain that red Stichopus Japonicus Selenka to lay eggs amount is big, and archiblast is good, and larva survival rate height has solved the red stichopus japonicus low problem of success rate of growing seedlings, and red stichopus japonicus is grown seedlings reach the level of high and stable yields.
Embodiment
During operation, at first select the specification of red stichopus japonicus parent participation, generally selecting body weight is that the individuality that 400-800 restrains is parent participation, cultivates under the water temperature at 12-13 ℃ by the density of 10 in every side's water and stores up, the nature bait of can throwing something and feeding during parent participation is stored up, the sea cucumber artifical compound feed of also can throwing something and feeding, through storing up after a while, parent participation is reached maturity, at this moment, parent participation sexual gland index is grown to 10-20%, and when ovum directly reached 190～200 μ m, the beginning artificial spawning was induced.The employing flowing water temperature-raising method that dries in the shade carries out ovum artificial collection.Adopt ovum and be chosen in and begin at dusk, the 1-1.5h that earlier parent participation dried in the shade, flowing water 0.5-1h makes the more former parent participation of ocean temperature store up water temperature then and raises 4～5 ℃, heats up and induces.Through the red Stichopus Japonicus Selenka to lay eggs inductivity of this method more than 80%.
Method of the present invention utilizes the suitable water temperature of storing up to stimulate with the flowing water intensification of drying in the shade with body weight, the index screening parent participation of sexual gland exponential sum ovum footpath, can carry out the ovum artificial collection of red stichopus japonicus effectively.
By growing seedlings in 2 years and forming test, worked out the technical method of artificial feeding of red stichopus japonicus, how to select parent participation size, the temperature of parent participation cultivation, the opportunity of induced spawning, the method for induced spawning during particularly red stichopus japonicus is grown seedlings, growing seedlings for red stichopus japonicus production provides guarantee.And the conventional breeding method of red stichopus japonicus larva, young ginseng breeding method and stichopus japonicus is similar.
