Catfishes (Ictaluridae) are among North America’s most important ichthyofauna for human consumption and recreation. As such, research on Blue Catfish Ictalurus furcatus, Channel Catfish I. punctatus, and Flathead Catfish Pylodictis olivaris has been abundant in historic and contemporary literature. A common technique for studying catfish involves marking or tagging fish to understand behavior, sampling efficiency, and population dynamics. Marking and tagging methods used in these studies may be divided into eight primary types, including fin clips, strap tags, anchor tags, transbody tags, injectable tags, skin alterations, origin markers, and telemetry. Each of these methods is appropriate for specific objectives and characterized by varying retention rates and data resolution (i.e., batch or individual identification) that warrant consideration when designing projects. For example, fin clips may be most appropriate as a short‐term mark requiring batch identification (e.g., stocking evaluation), whereas telemetry might be most appropriate as a long‐term tag requiring individual identification (e.g., habitat selection). This review summarizes marking and tagging methods used for evaluation of Blue, Channel, and Flathead catfish and synthesizes results using examples from previously conducted catfish research. Further discussion is included on information gaps, emerging trends, and guidance for scientists planning and conducting studies that require marking of catfish.

蓝Cat鱼，斑Channel鱼和Flat鱼的标记和标记方法综述

fish鱼（Ictaluridae）是北美最重要的人类食用和娱乐鱼类。因此，对蓝Cat鱼Ictalurus furcatus，Channel鱼I进行了研究。毛虫，并铲鮰Pylodictis olivaris在历史和当代文学中已经很丰富。研究cat鱼的常用技术包括对鱼进行标记或标记，以了解其行为，采样效率和种群动态。这些研究中使用的标记和标记方法可以分为八种主要类型，包括鳍夹，皮带标记，锚定标记，身体标记，可注射标记，皮肤改变，起源标记和遥测。这些方法中的每一种都适用于特定的目标，其特点是保留率和数据分辨率（即批或个人标识）不同，因此在设计项目时应予以考虑。例如，鳍夹可能最适合作为需要批量识别的短期标记（例如，库存评估），而遥测作为需要个体识别（例如，栖息地选择）的长期标签可能最为合适。这篇综述总结了用于评估蓝，Channel和Flat鱼的标记和标记方法，并使用先前进行的cat鱼研究的实例综合了结果。进一步的讨论包括信息空白，新兴趋势以及为计划和进行需要标记marking鱼的研究的科学家提供的指导。
