Daily movement behavior of two Neotropical armored catfish species (Ancistrus aff. cirrhosus Valenciennes, 1836 and Hypostomus ancistroides Ihering, 1911) at a road‐stream crossing culvert. Journal of Applied Ichthyology, 2017(00), 1–8. DOI: 10.1111/jai.13446

We hypothesized that the use of habitat by two armored catfish species, Ancistrus aff. cirrhosus and , which share the same stream reach, is temporally segregated. To test this, fish residence time within a culvert and fish movements through the culvert were analyzed in relation to the daily hours, lunar cycle and discharge using Passive Integrated Transponder telemetry. The residence time for A. aff. cirrhosus conducting upstream movements was longer than H. ancistroides. Both species exhibited high nocturnal activity, although at different periods: A. aff. cirrhosus was most active at dawn (00:00–05:59 hr), while H. ancistroides exhibited intense activity at night (18:00–23:59 hr), indicating temporal segregation of movement behavior between species. In addition, A. aff. cirrhosus was most active in the new moon phase and when there was high water discharge, while H. ancistroides was most active only when there was high water discharge. This study elucidates the patterns of daily movement behavior and temporal habitat use of these fish species.
