Description
Technical field
The invention belongs to aquacultural engineering field, specifically a kind of adherance and supporting device of collecting seedling thereof of producing oyster monomer seed.
Background technology
At present, the acquisition of oyster monomer seed mainly contains three kinds of modes: the one, adopt the drug-treated such as adrenaline or 5-HT by the oyster larva in the eyespot phase, make that larva is non-cohesive completes metamorphosis, thereby obtain monomer juvenile mollusk (Grant, M.N., D.W.Meritt&D.G.Kimmel.2013.Chemicalinductionofsettlement behaviorinlarvaeoftheeasternoysterCrassostreavirginica (gmelin) .Aquaculture402-403:84-91.; MesAquaculture40, C., A.Silva, V.Maneiro, A.Pazos, J.L.SL.SL.SJ.L.S, A.Parall..2013.Effectsofchemicalcuesonlarvalsettlementof theflatoyster (Ostreaedulis): Ahatcheryapproach.Aquaculture376-379:85-89.; Teh, C.P., Y.Zulfigar, S.H.Tan.2012.Epinephrineand1-dopapromotelarvalsettlement andmetamorphosisofthetropicaloyster, Crassostreairedalei (faustino, 1932): Anoysterhatcheryperspective.Aquaculture338ture360-263.); The 2nd, on the smooth adherance surface that oyster larva is attached to easily peel off (as polyethylene film, corrugated plating etc.) then carry out manual removal (Yang Aiguo, Niu Xiduan .1995. Pacific oyster monomer seed produces and the research of cultural technique. Chinese aquatic science 2 (3): 29-35.; Li Shilei, Chang Yaqing .2008. cultchless oyster rearing of fingerling progress. Beijing aquatic products 109:37-38.); The 3rd, use particle adherance that larva is adhered to, juvenile mollusk after growing up still for monomer (Li Shilei, Chang Yaqing .2008. cultchless oyster rearing of fingerling progress. Beijing aquatic products 109:37-38.). Generally adopt at present the mode of production of adrenaline processing abroad; And first adhere to, to peel off be afterwards a kind of mode of production of domestic current more employing; Particle adherance only has report in scientific experiment, and commercial application has no report. It is strict that chemicals processing exists operating technology to require, and timing node control is accurate, and medicine cost is high and can not recycle, to the more high restriction of practitioner's competency profiling. Tradition is first adhered to the method for peeling off afterwards, and not only production efficiency is low, and larva shell is easily squeezed broken in operating process, and large-scale promotion exists difficulty.
