Abstract

ObjectiveVisible implant elastomer (VIE) tags are commonly used as a cost‐effective tool for marking small fish, making them valuable in mark–recapture studies. It is crucial to quantify the impact of tagging procedures on fish survival to address inferential bias in mark–recapture studies. We assessed marking‐related mortality and growth in American Eel Anguilla rostrata elvers in a 40‐day laboratory experiment, following VIE tag application.MethodsThere were 500 elvers (80–149 mm) that were divided into four treatment groups and one control group. Treatment groups were tagged with two tags in three body locations (anterior, central, posterior on left bilateral side) or with two tags in all three locations, while the control group remained untagged. Eels were retained in experimental tanks, and mortality rates were compared.ResultThe VIE tagging did not significantly affect survival, which was 90.9% across all treatment groups and 92% for the untagged control group; nor did it affect growth.ConclusionThe application of VIE tags on various body parts should be a safe and effective method for marking American Eel elvers.

用可视植入弹性体标签标记的美洲鳗鲡的短期存活和生长情况

目标可视植入弹性体（VIE）标签通常作为一种经济有效的工具用于标记小型鱼类，使其在标记重捕研究中具有重要价值。量化标记程序对鱼类存活率的影响对于解决标记再捕获研究中的推断偏差至关重要。我们在一项为期 40 天的实验室实验中评估了美洲鳗鲡（Anguilla rostrata elvers）在使用 VIE 标签后与标记相关的死亡率和生长情况。处理组在身体的三个位置（前部、中部、左侧后部）贴两个标签，或在所有三个位置贴两个标签，而对照组则不贴标签。在鳗鱼身体的不同部位贴上 VIE 标签应该是一种安全有效的标记美洲鳗鲡的方法。

期刊介绍： The North American Journal of Fisheries Management promotes communication among fishery managers with an emphasis on North America, and addresses the maintenance, enhancement, and allocation of fisheries resources. It chronicles the development of practical monitoring and management programs for finfish and exploitable shellfish in marine and freshwater environments. Contributions relate to the management of fish populations, habitats, and users to protect and enhance fish and fishery resources for societal benefits. Case histories of successes, failures, and effects of fisheries programs help convey practical management experience to others.
