中文摘要:
      以麻醉剂2-苯氧乙醇浓度(50、100、200、400、600、800、1 000 μL/L)、暴露时间(2、4、8、12、16、32 min)和溶解氧浓度(4、8、12、16、18、22 mg/L)作为参考指标,研究2-苯氧乙醇对扁吻鱼(Aspiorhynchus laticeps)幼鱼[(9.91±0.31)g]的麻醉效果。结果表明:麻醉时间与麻醉浓度呈负相关,复苏时间与麻醉浓度呈正相关。当浓度≤ 200 μL/L,扁吻鱼幼鱼的呼吸频率在初期会下降,随后上升并维持在11次/10 s,当浓度≥ 400 μL/L时,呼吸频率随着麻醉时间的增加下降,直至休克。当浓度为800和1 000 μL/L时,幼鱼可在3 min内麻醉,并且在5 min内苏醒,因此,扁吻鱼幼鱼的最适麻醉浓度范围为800~1 000 μL/L。在高浓度麻醉下,随着暴露时间的增加,幼鱼的复苏时间减短,当暴露32 min时,幼鱼仅(100.51±10.60)s就可以复苏(P<0.05)。不同氧浓度下,幼鱼的复苏时间存在差异,其中12 mg/L最低只需(129.00±36.50)s,22 mg/L最高需(406.33±53.20)s,是12 mg/L的3.15倍(P<0.05)。
英文摘要:
      Aspiorhynchus laticeps belongs to Osteichyes, Cyprinformes, Aspiorhynchus Kessler, and was mylopharyngondon piceus. A. laticeps was national level to protect animals, so it had very important economic and scientific values. Because 2-phenoxyethanol was easy preparation, low price and rapid action, it acts as a general anaesthetics in fish. This paper regarded anaesthetics concentration(50, 100, 200, 400, 600, 800, 1 000 μL/L), exposure duration(2, 4, 8, 12, 16, 32 min) and dissolved oxygen concentration(4, 8, 12, 16, 18, 22 mg/L) as reference indices, and the effects of 2-phenoxyethanol were focused on as anaesthetics on juvenile A. laticeps(9.91±0.31g). Result showed that induction time and anaesthetics concentration were negative correlation, however recovery time and anaesthetics concentration were positive correlation. Respiratory rate of A. laticeps would decrease when concentration under 200 μL/L in initial period, but would be 11times/10s at mid-late period. Opercular movement frequency decreased with increasing doses of anaesthetics when concentration was equal or greater than 400 μL/L, and at last. juvenile A. laticep would cease respiration. Juvenile A. laticep could be anaesthetized in less than 3 min, with recovery in less than 5 min at 800 and 1 000 μL/L, so effective anaesthesia range was from 800 to 1 000 μL/L. In high concentrations, recovery time decreased with increasing exposure time. Juvenile A. laticep could recover in (100.51±10.60) seconds(P<0.05. Because of different dissolved oxygen concentration, there were differences between recover time:12 mg/L would recover in less than (129±36.50) seconds, which was lowest. 22 mg/L would recover in (406.33±53.20) seconds, which was highest. The highest group was 3.15 times higher than the lowest group (P<0.05).
