PIT tagged fish from Dale River for Hulbak et al.

Salmon smolts were PIT tagged in Dale River in 2019 and recaptured at a wolf trap. There are multiple tagging groups at different times of the year to assess the impact of tag timing on growth, migration timing, and migration phenotype

2019年，研究人员在戴尔河（Dale River）对鲑鱼幼鲑（Salmon smolts）实施了PIT（Passive Integrated Transponder，被动集成应答器）标签标记，并在狼陷阱中完成了个体重捕。为评估标记时机对幼鲑生长、洄游时间及洄游表型的影响，本研究设置了多个一年中不同时段的标记组。
