两条雌性须1989年4月12日至7月7日，在比利时南部的乌尔特河（Ourthe River）用植入式无线电发射器标记并跟踪它们，以研究它们在春夏期间的运动和活动节律。这两个触须定义了一个1.6公里的家庭范围，并占据了四个居住区。最大的平均日移动范围内的家庭范围限制发生在prepawning和产卵期，并与平均每日水温和水平的变化。巴贝尔2号从它的春季家园出发，进行了9.6公里的短途旅行，一周后回到了它的居住区。触须显示黄昏和黎明的活动模式，其特点是占领浅滩地区。活动时间被发现是依赖于水温，而每天的活动面积的大小受河流流量条件的影响。
Two female barbel Barbus barbus (L.) were tagged with implantable radio transmitters and tracked in the Ourthe River (Southern Belgium) from April 12th to July 7th, 1989 to study their movements and activity rhythms during the spring-summer period. Both barbels defined a 1.6 km home range and occupied four residence areas. Greatest average daily movements within the home range limits occurred during the prespawning and spawning periods and were associated with variations of mean daily water temperature and level. Barbel 2 made a 9.6 km excursion from its spring home range and homed a week later in its residence area. Barbels displayed dusk and dawn activity patterns, characterized by the occupation of riffle areas. The activity timing was found to be dependent on water temperature while the size of daily activity area was more influenced by river flow conditions.
