Description

The red spirodromy attitude of arteries and veins seedling-cultivating method
Technical field
The present invention relates to the red spirodromy attitude of red spiral shell seedling-cultivating method, the especially arteries and veins of a kind of arteries and veins seedling-cultivating method.
Background technology
Red spiral shell (the R of arteries and veins Apana vanosa) be commonly called as red spiral shell, mainly be distributed in the Bohai Sea, the Huanghai Sea, the East Sea and the South Sea, Japan is coastal and the coastal distribution in the Korea peninsula is also abundanter.Littoral output is less at China South Sea, and the Bohai Sea, Huanghai Sea output are bigger.The red breechblock type of arteries and veins is bigger, and the high 110~120mm of adult shell (maximum 140mm), its foot are loose especially, and nutritive value is abundant, and delicious flavour for Modern Family, the rather well received delicious food of hotel dining table, is usually used in replacing abalone.The red spiral shell of arteries and veins is except that eating raw, and can or dried product are made in multi-processing, and market prospects are wide.Since the last century the eighties, because excessive amount of fishing, the red spiral shell natural resources of arteries and veins is close to exhaustion, its market price rising all the way.For meeting the need of market, recover the red spiral shell resource of arteries and veins, carry out and to promote the artificial breeding and the breed of the red spiral shell of arteries and veins extremely urgent.
The red spiral shell fast growth of arteries and veins, carnivorous because of it, the staple food bivalve shellfish can well be controlled the growth and the density of bivalve shellfish in ecological cultivation, be to solve that the marine eco-environment that shallow sea, pond and mudflat aquaculture in the past cause because of kind is single worsens, the frequent desirable kind that takes place of disease.Multiple breeding way such as the red spiral shell of arteries and veins is fit to that the raft formula is raised in cages, mesh bag is flatly supported, broadcast at the bottom of the seabed are a good alternative kind of present raft culture and a foster kind, also are well to raise together with kind in the ecologic breeding of pond.
Make a general survey of domestic and international present Research; the report that the red spiral shell reproductive biology research of arteries and veins few in number is only arranged; the artificial breeding of the red spiral shell of arteries and veins is in the small scale experiments stage substantially; because of major technique can't break through; there are problems such as seedling cost height, output of seedling are few, emergence rate instability, can't realize the scale breeding demonstration effect.The red spiral shell development of fertilized ova of arteries and veins become need behind the veliger through with the phytoplankton be food floating larva gradually metamorphosis be the young spiral shell of dwelling the end of animal feeding habits, in the artificial breeding of the red spiral shell of arteries and veins, the end crawl after as the metamorphosis spatfall base of the young of young spiral shell corrugated plating with benthic diatom commonly used of dwelling, young feeding habits are converted to the animal feeding habits because of crawling, need to spread fresh clam meat fragment as bait to the adherance throwing, because the rotten deterioration that causes the water quality of growing seedlings of residual bait on the adherance and ight soil, the survival rate of the young is low, can't realize the batch process of commercial seedling always, have a strong impact on the development of the red spiral shell breed of arteries and veins scale.
Summary of the invention
Is bait in order to overcome indoor raising of seedling with fresh clam meat fragment, residual bait and ight soil are rotten to cause water quality deterioration to have a strong impact on the survival rate of the young, the invention provides the red spiral shell mesh bag of a kind of arteries and veins (cage) ecological breeding method, this method makes that survival rate significantly improves in the red spiral shell feeding habits of the arteries and veins transfer process.
The technical solution adopted for the present invention to solve the technical problems is: a, water temperature is adopted the red spiral shell of the arteries and veins of catching parent spiral shell in 10~25 ℃ natural waters, putting into indoor close spiral shell cultivation pond fattens, parent's spiral shell male and female are than being 1:1, and the fattening pond water temperature is 12~26 ℃, and it is 3~5/m that the red spiral shell parent of arteries and veins spiral shell is supported density temporarily 3B, fatten bait with bivalve shellfishs such as live body mussel, oyster and scallops as the red spiral shell of arteries and veins parent spiral shell, every day, full dose was changed water, and cleaning ight soil and dead bait, replenished bait according to residual bait situation, and the red spiral shell parent of the arteries and veins spiral shell that in time will shift out the water surface in the daily management pushes in the water; Parent's spiral shell begins mating when 15~26 ℃ of c, water temperature, the 2nd~5 day output oopod of post-coitum, and oopod scrapes oopod along the oopod base portion with scraper attached to pool wall, Chi Dishang at the bottom of pool wall, pond; D, the oopod that scrapes is moved in 10~20 order plastics net cages, the hatching that in nursery pond, suspends, hatching density is 5000~8000 oopod/m 3, continuous charge, 20~24 ℃ of hatching water temperatures; E, from oopod, hatch when floating larva, when density reaches 1~3/ml in nursery pond, temporary unhatched oopod in plastics net cage and the plastics net cage is moved into new nursery pond continue hatching; F, the unit cell algae that swims of in the nursery pond that hatches the young, throwing something and feeding, feeding volume: 1.0~12.0 * 10 4Individual/ml day, hatch and threw something and fed 1 the same day, threw something and fed 3-4 time in the 2nd day, divide the 3rd day later every day and throw something and feed for 5~6 times, cultivate 22~26 ℃ of water temperatures, continuous charge, day quantity of exchanged water 1/2; G, cultivate 3 gyrations when floating larva, size 700~800 μ m, with the animal bait of 1.0~1.5mm bivalve spat after as the red spiral shell metamorphosis of arteries and veins, the 3 gyration young and bivalve spat number are put into mesh bag that 60 order polythene nets make or cylinder mould or net cage in the ratio of 1:3 to 1:4 plunges into the commercial sea, mesh bag specification 70cm * 50cm, hold bag with polythene net sheet or nettle, 500~1000 of the 3 gyration young amounts of putting into; Cylinder mould format diameter 30-40cm, high 100cm divides 5 layers, 200~500 of every layer 3 gyration young amounts of putting into; The long 2m of cage size, wide 2m, high 1m, the 3 gyration young amount of putting into 10000-15000 grain/m 3
The invention has the beneficial effects as follows: pack into jointly 60 order mesh bags, cylinder mould or net cage of the young spiral shell of 3 gyrations and living bait (bivalve seedling) plunged into the commercial sea, young spiral shell is finished the conversion of plant feeding habits to the animal feeding habits at natural waters, the little algae of natural waters and be attached to mesh bag (cage) and the benthic diatom on bivalve seedling surface ingests early stage, later stage the bivalve seedling that ingests, this method not only makes indoor culture finish in 40 days in advance, changes the water cost savings more than 50%; And effectively avoided cultivating the water quality corruption of using clam meat, the flesh of fish etc. to cause in the pond, reduced the influence of drug administration to the seed quality safety; in the past Little naturally algae-young shellfish-young spiral shell forms good food chain in the mesh bag (cage) simultaneously, saved indoor cultivation bait service cost, and living bait is nutritious, and young spiral shell distortion ratio height, young spirodromy length are soon; Because young spiral shell in advance obtains taking exercise at natural waters, so commercial seedling stalwartness, survival rate height.
