摘要


本實驗以不同濃度的2-phenoxyethanol對黑鯛、七星鱸、吳郭魚和胎鱂魚進行麻醉。實驗發現,隨著麻醉劑濃度增高,麻醉誘導時間會減短,但恢复時間卻未因麻醉劑濃度不同而有顯著變化。不同魚種在相同濃度之2-phenoxyethanol麻醉下的麻醉誘導時間亦有差異。400 ppm的2-phenoxyethanol已可使黑鯛與七星鱸在3分鐘內被麻醉。但對吳郭魚和胎鱂魚,即使600 ppm仍無法使牠們在3分鐘內被麻醉。因此要有效麻醉這兩種魚類,可能需要更高的2-phenoxyethanol濃度。

並列摘要


Four species of teleost(Acanthopagrus schlegeli,Lateolabrax japonicus,Oreochromis mossambicus,and Poecilia velifera)were anesthetized with differentconcentrations of 2-phenoxyethanol(2-PE).Induction time of all fishes decreasedwith increasing concentrations of 2-PE but recovery time was concentration-inde-pendent.The induction time of the four fishes anesthetized with same concentrationof 2-PE varied.A.schlegeli and L.japonicus were anesthetized within 3 minin 400 ppm 2-PE solution.The induction time for O.mossambicus and P.veliferaat the concentration of 600 ppm was,however,longer than 3 min.Therefore,toanesthetize the latter two fishes effectively,higher concentration of 2-PE may benecessary.
