<p>A controlled experiment to test effects of tagging on survival of monkfish and to investigate tag retention. Thirty-four monkfish ranging in size from 40-78 cm were captured in gillnets on Dec. 11-15, 2006, and transported to the lab as described above except that time from capture to release in the lab was reduced to a maximum of 12 hr and Amquell was used in the on-board tank and transport coolers. The transport coolers were also dosed with Slime Coat at the recommended concentration. The fish were held for up to six weeks in two tanks (2600 gallon) supplied with ambient (5- 8 oC) running seawater. Eighteen monkfish were tagged 4-10 days after their arrival in the laboratory, the remaining 16 fish were left untagged to serve as controls. Nine tagged fish and 8 control fish were placed in each tank. We attempted to match controls and tagged fish for size and condition. We offered food (squid or capelin) daily; however, the food was rarely taken. The experiment was terminated 40 days after the final batch of monkfish was tagged. Remaining monkfish were euthanized, released or held for longer term observation. Survival curves of tagged and control fish were compared using Proc Lifetest (SAS System, Allison 1995)</p>

<p>本研究为对照实验，旨在探究标记操作对美洲鮟鱇存活率的影响，并考察标记留存情况。2006年12月11日至15日，研究人员采用刺网捕获34尾体长介于40~78 cm的美洲鮟鱇。运输及实验室暂养流程参照既定方案，但将捕捞后至实验室暂养的最长时长压缩至12小时以内；船上暂养池与运输冷却箱内均使用Amquell药剂，并按照推荐浓度向运输冷却箱中投加Slime Coat制剂。实验鱼被放置于两个容积为2600加仑的水槽中暂养，水槽采用5~8 ℃的自然流动海水，暂养周期最长达6周。鮟鱇抵达实验室4~10天后，研究人员为其中18尾个体实施标记操作，剩余16尾作为空白对照不予标记。每个水槽中放置9尾标记组个体与8尾对照组个体，研究人员尽量在体长与健康状态上匹配对照组与标记组个体。研究人员每日投喂鱿鱼或毛鳞鱼作为饵料，但鮟鱇极少摄食。末次标记操作40天后，本实验终止。剩余的美洲鮟鱇个体被实施安乐死、放归野外，或继续暂养以开展长期观测。研究人员采用SAS系统的Proc Lifetest程序（Allison, 1995）对标记组与对照组鮟鱇的存活曲线进行比较分析。</p>
