Description
Technical field
The invention belongs to the batch production Seedling production field of aquaculture, the specifically oopod collection of a kind of Rapana venosa industrial seedling rearing and hatching apparatus and using method thereof.
Background technology
Rapana venosa (Rapanavenosa), is commonly called as " spinach spiral shell ", " Carnis Rapanae thomasianae ", belongs to Mollusca, Gastropoda, Muricidae, and red spiral shell belongs to, and adult shell is high up to 7��12cm, and China Bohai Sea and the Huanghai Sea all have distribution. Its foot is loose especially, and delicious flavour is nutritious, very people institute eating, and economic worth is high. In the last few years, along with the situation of selling well of the decline of Rapana venosa near-coastal resources and domestic and international market, its economic worth improved constantly, and current live body price is 20��40 yuans/kilogram.
At present, Rapana venosa has the very big market demand in China Bohai Sea and Huanghai Sea bank, from the nineties in last century, some R&D institutions and nursery enterprise attempt carrying out artificial breeding, but mostly are failure, emerge extremely inefficient, also realize far away industrialized scale, cause that artificial cultivation cannot carry out on a large scale.
At present, Rapana venosa seed breeding technology just breaks through, and industrialized culture is in the starting stage, and the breeding phase of Rapana venosa parent shellfish lacks efficient oopod collection and hatching apparatus. The female spiral shell of Rapana venosa is liked in laying eggs in backlight, the curved surface of rough surface and one-tenth certain radian. Owing to the female spiral shell of Rapana venosa is to be originated in by oopod in shaggy substrate, laid eggs bag becomes tufted, and its base portion adheres in substrate, is therefore difficult to separate substrate, slightly improper oopod will cause huge damage. At present, in Rapana venosa industrial seedling rearing process, Rapana venosa parent's spiral shell is many to be cultivated in floating frame, therefore and be unfavorable for that female spiral shell is laid eggs its oopod originates on corner and the floating frame skeleton of floating frame net wall more, and due to net wall and floating frame skeleton, to be available for the area of plane that female spiral shell lays eggs less, it is also easy to cause oopod stacking, it is difficult to the problems such as stripping, causes that oopod loss rate is big, the problems such as incubation rate is low.
Summary of the invention
