Última Movements through a fish ladder: temporal patterns and motivations to move upstream Neotropical Ichthyology Agostinho,Carlos Sérgio; Pereira,Celiana Ribeiro; Oliveira,Rafael José de; Freitas,Iriene Siqueira; Marques,Elineide Eugênio. Fish passages are constructed with the aim of reestablishing connectivity between critical habitats, in order to sustain those species that move over a large area during their lives. The upstream movements of most of the known migratory species are made for purposes of reproduction (adults) or dispersal (juveniles). The present study was conducted at the ladder constructed at Lajeado Dam (Luis Eduardo Magalhães Hydroelectric Power), on the Tocantins River. The objective was to assess whether there is a temporal pattern in the abundance of fish below the dam and in the ladder, that correlates with their breeding seasons. Additionally, it was examined whether reproduction is the predominant motivation of the shoals of fish that ascend the ladder. Samples...
