Abstract

The current study had the objective of determining temporal patterns of fish passage in Santa Clara Power Plant's fish lift, Mucuri River. During four months, from November 2003 to March 2004, transposition cycles were performed each two hours, when the specimens were counted and identified. During this migration period 67,838 individuals of 31 species passed through the lift. Migratory Characiformes abundance was larger during the day, whereas the Siluriformes were registered mainly at night. Fish abundance in the lift was significantly related to the Mucuri river flow. The temporal pattern found makes possible a better utilization of the lift, focusing cycles during the day and high flows periods.
