Abstract
The invention relates to industrialized seedling culture production of aquiculture, in particular a seedling collecting facility and method of industrialized rapana venosa seedling culture. The seedling collecting facility comprises plastic corrugated sheets with rough surfaces and a bracket fixing the corrugated sheets. The plastic corrugated sheets are fixed in clamping troughs on the bracket in parallel, and ropes in parallel to clamping trough connecting rods are enlaced at the side face opposite to the clamping trough connecting rods. In the method, juvenile oyster mollusks, used as animal baits in the eating pattern transformation and metamorphosis process of rapana venosa larvae, are adhered to the plastic corrugated sheets firstly before the seedling collecting facility is put into use; when more than 50% of the rapana venosa larvae grows to the later stage of three spiral whorls to the initial stage of four spiral whorls, the seedling collecting facility is put into use as the plastic corrugated sheets are in multi-plane three-dimensional layered mode in a seedling culture pond, and the rapana venosa larvae are adhered to the plastic corrugated sheets adhered with the juvenile oyster mollusks to complete the eating pattern transformation and metamorphosis process and carry out juvenile rapana venosa intermediate culture. By adopting the invention, the eating pattern transformation and metamorphosis process ofthe rapana venosa larvae can be completed successfully in industrialized seedling culture.
Description
Technical field
The batch production seed that the present invention relates to aquaculture produces the collect seedling facility and the method for the red spiral shell factorial seedling growth of specifically a kind of arteries and veins.
Background technology
The red spiral shell Rapana of arteries and veins venosa is commonly called as " watt spiral shell ", " conch ", belongs to Mollusca, Gastropoda, Muricidae, and red spiral shell belongs to, adult shell Gao Keda 11-12cm, and China Bohai Sea and the Huanghai Sea all have distribution.Its foot is loose especially, delicious flavour, and nutritious, very people like food, and economic worth is high.In the last few years, along with decline and this kind commodity of near-coastal resources are in great demand in the domestic and international market, its economic worth improved constantly, and the live body price is 20～40 yuans/kilogram at present.
At present, the red spiral shell of arteries and veins has the very big market demand in China Bohai Sea and Huanghai Sea bank, since the nineties in last century; Some R&D institutions and the enterprise of growing seedlings attempt carrying out artificial breeding, but are mostly failure, and the efficient of emerging is extremely low; Also realize industrialized scale far away, cause propagating artificially and can't carry out on a large scale.
At present, the main factor that causes the red spiral shell seed breeding of arteries and veins technology not reach a standard is the feeding habits transfer problem that does not solve the red spiral shell larva of arteries and veins well.So-called feeding habits conversion is meant in the red spiral shell larval metamorphosis of the arteries and veins process and need transfers ingestion animal property bait to by vegetal baits such as the unit cell algaes that ingests.The feeding habits conversion is very crucial stage in the red spiral shell growth course of arteries and veins, and the death of most of larva all occurs in this developmental stage.In the red spiral shell factorial seedling growth of arteries and veins process, the animal bait major part of using at present is the muddy flesh of bivalve shellfish (like clam son, oyster, mussel etc.).Use the bivalve shellfish muddy flesh very easily to cause water quality to ruin, cause larva dead on a large scale, make the failure of growing seedlings as animal bait.
Summary of the invention
The object of the present invention is to provide the collect seedling facility and the method for the red spiral shell factorial seedling growth of a kind of arteries and veins, solve the feeding habits conversion and abnormal and young spiral shell intermediate rearing problem of the red spiral shell larva of arteries and veins.
