Winter is a challenging period for aquatic research—weather is uncomfortable, ice is hazardous, equipment fails, and daylength is short. Consequently, until recently relatively little research on freshwater fishes has included winter. Telemetry methods for tracking fish and observing movement behavior are an obvious solution to working in harsh conditions because much of the data can be collected remotely, and passive methods collect data year-round without winter maintenance. Yet, many telemetry studies do not collect data during winter or, if they do, only report data from the ice-free seasons while the remaining data are unused. Here, we briefly summarize the advantages and limitations of using telemetry methods in winter, including acoustic and radio telemetry and passive integrated transponder technology, then review the range of questions related to fish ecology, behavior, bioenergetics, and habitat use that can be addressed in winter using telemetry. Our goals are to highlight the untapped potential of winter fish biology and to motivate scientists to revisit their four-season telemetry data and incorporate objectives specific to winter biology in future study plans.

冬季是水产研究的一个充满挑战的时期-天气不舒服，冰很危险，设备出现故障并且白天很短。因此，直到最近，有关淡水鱼类的研究还很少包括冬季。跟踪鱼类并观察运动行为的遥测方法是在恶劣条件下工作的明显解决方案，因为许多数据可以远程收集，而被动方法则全年收集数据而无需冬季维护。但是，许多遥测研究没有在冬季收集数据，或者如果收集了数据，则仅报告无冰季节的数据，而其余数据未使用。在这里，我们简要概述了在冬季使用遥测方法的优点和局限性，包括声学和无线电遥测以及无源集成转发器技术，然后回顾与鱼类生态，行为，生物能和栖息地使用有关的一系列问题，这些问题可以在冬季使用遥测技术解决。我们的目标是强调冬季鱼类生物学尚未开发的潜力，并激励科学家重新审视其四个季节的遥测数据，并将冬季生物学特有的目标纳入未来的研究计划中。
