The macrophytes aquatic colonize mainly the arms of the reservoirs and / or areas protected from the action of the wind and of the currents. Studies about the fish fauna associated with the bank macrophytes aquatic demonstrate that the presence of this type of vegetation is fundamental in the selection of habitats by the fish. The objective of this work is to characterize the composition, taxonomic, and richness and diversity of the fish fauna associated with the macrophyte water in the river Areias. The collections were carried out quarterly between the months of January to October 2016, banks of macrophytes aquatic mixed. Were collected 1.333 individuals, belonging to 21 species, distributed in five orders and 11 families. The Characiformes were characterized as the dominant order throughout the period of the study. Being that the species Hyphessobrycon moniliger, Hemigrammus ora and Hemigrammus rodwayi were the most captured. |
