Abstract

This work studied the composition and abundance of the fishes that move between macrophyte
banks and open water during the morning twilight (CM) and afternoon twilight (CV). The collections
were made using gillnets, along banks of Paspalum repens, at Catalão lake, in Amazonas, Brazil. A
total of 222 individuals and 37 species were collected. Of these, 130 individuals were collected
during the CM and 92 during the CV; 80 individuals were leaving during the CM and 40 individuals
were leaving during the CV. Auchenipterus nuchalis, Pellona castelnaeana, Triportheus angulatus and
T. albus were the most common and concentrated species collected in the CM and Pimelodus blochii
was the most common species collected in the CV.
