本實驗中，利用不同濃度的麻醉劑 2-phenoxyethanol (2-PE) 對黑鯛進行麻醉後，檢測其血液學指數的變化。實驗結果顯示，在 400 及 600 ppm 的 2-PE 溶液中，黑鯛在 3分鐘內即進入完全失去平衡後期；牠們的各項血液學指數與對照組之間並無顯著差異 (p >0.05)。在濃度為 200 ppm 中，由於黑鯛無法在 30 分鐘內被麻醉至完全失去平衡後期，因此，在麻醉進行 15 分鐘後即進行抽血採樣。結果發現，本麻醉組魚的血容積比明顯低於對照組，而血糖值則顯著高於對照組。綜合上述結果，我們認為以較高濃度麻醉劑快速麻醉魚類時，引起其所產生之壓迫反應較小。

In this study, we examined changes of hematological parameters in blackporgy Acanthopagrus schlegeli after anesthetization in 2-phenoxyethanol (2-PE)of various concentrations. In 400 and 600 ppm 2-PE solutions, black porgies wereanesthetized to total loss of equilibrium within 3 min. The all values ofhematological parameters of the anesthetized fishes were not significantlydifferent between the anesthesia and control groups (p > 0.05). In 200 ppm 2-PEsolution, since the fish could not be anesthetized to total loss of equilibriumwithin 30 min, we tested the black porgies which have been anesthetized for 15min in this solution and found that the fish showed significantly decrease inhematocrit and increase in plasma glucose. It is, therefore, concluded thathigher dosages of 2-PE will take shorter time to induce less stress effect onthe anesthetized fish.
