Abstract

The effects of tricaine methanesulfonate (MS-222), a commonly used fish anesthetic, on plasma nonesterified fatty acid levels (NEFA) were examined in rainbow trout, Oncorhynchus mykiss. Total NEFA levels declined with increasing duration of exposure to MS-222. Most of the decline in total NEFA was due to decreases in saturated fatty acids (14:0, 16:0 and 18:0). The fatty acid displaying the most rapid response to exposure to MS-222 was 20:5n-3. The lower plasma NEFA levels in anesthetized fish may be explained by depressed lipolysis in the presence of the anesthetic.

摘要

研究了常用鱼类麻醉剂甲磺酸三卡因（MS - 222）对虹鳟（Oncorhynchus mykiss）血浆非酯化脂肪酸水平（NEFA）的影响。随着暴露于MS - 222的时间延长，总NEFA水平下降。总NEFA的大部分下降是由于饱和脂肪酸（14:0、16:0和18:0）减少所致。对暴露于MS - 222反应最迅速的脂肪酸是20:5n - 3。麻醉鱼血浆NEFA水平较低可能是由于麻醉剂存在时脂解作用受抑制所致。
