Regulation for hydroelectric production (i.e., hydropeaking) can impact aquatic species life cycle. During 2016–2017, radiotelemetry was used to track 22 Iberian barbels during a 1‐year cycle in a flow regulation scenario. Periodic samples of scales and biometric data were collected in a regulated (hydropeaking regime) and non‐regulated river within the same basin for comparison. Collected tracking, growth and condition data were compared with similar information for the same barbel population, obtained exactly on the same river stretch in a pre‐regulation period (2013–2014). Results on movement patterns of target species showed no effect of regulation on this biological component. However, potential intraspecific differences on migratory behaviour were found. We identified two behavioural profiles in each of the tagged fish groups: a ‘resident’ group that remains in upstream areas of the river during all the year round [maximum distance travel: mean (±SD) = 5.44 ± 5.36 km] and a ‘potamodromous’ group that travels long distances downstream after the reproductive season (20.24 ± 6.30 km).

流量调节对水力发电鱼类运动方式，生长和状况的影响

水力发电生产（即水峰）的监管可能影响水生物种的生命周期。在流量调节方案中，2016年至2017年期间，无线电遥测技术在1年的周期内用于跟踪22条伊比利亚口须。定期在同一流域内经调节（水峰期）和未经调节的河流中收集规模和生物数据的样本，以进行比较。将收集到的跟踪，生长和状况数据与相同口须种群的相似信息进行比较，这些数据是在管制前时期（2013-2014年）在同一条河段上精确获得的。目标物种运动模式的结果表明，对该生物组分没有调节作用。但是，发现了迁徙行为的种内差异。我们在每个标记的鱼群中确定了两个行为特征：
