The aim of this study was evaluate the ecological aspects related to relative growth, size at first maturity, reproduction, energy investment, sex ratio and diet of the driftwood catfish Auchenipterichthys longimanus (Siluriformes: Auchenipteridae) from the rivers of Caxiuanã National Forest, State of Pará, Brazil. The samplings were carried out bimonthly from July 2008 to July 2009. In this period, 625 specimens of A. longimanus were captured, which 338 were females, 251 males and 36 macroscopically undefined individuals. The results indicated a polyphasic growth pattern for both sexes, and the stanza changing point was about 11.5 cm for males and 12.5 cm for females, values close to the estimated size at first maturity (L50). Through the ...
