Última Structural indexes and sexual maturity of tambaqui Colossoma macropomum (cuvier, 1818) (Characiformes: Characidae) in Central Amazon, Brazil BJB VILLACORTA-CORREA,M. A.; SAINT-PAUL,U.. Length, weight, structural index and sexual maturity in tambaqui Colossoma macropomum were analysed. 449 specimens were obtained from the commercial fishing fleet arriving at Manaus Harbour from the floodplain areas from May 1992 to July 1993. The objective of this study is to describe changes in structural index during one hidrological cycle and to interpret them according to the water level fluctuations and to also determine the time, reproductive period and length in sexual maturity. Sex ratio in tambaqui was 1:1 however, the length of females was significantly longer than males'. Length/weight relationship was described by the expression: Pt = 0.00058*Cp2.9039. b value was significantly different from 3 which meant an alometric growth. Lower condition...
