摘要：
Length-weight (LWR) and length-length (LLR) relationships were estimated for 20 species and lengths at first maturity (L-50) for six species of freshwater fishes caught in the Salto Santiago Reservoir, Iguacu River Basin, Brazil. In nine species significant differences were found in the LWR between sexes. Average b-value for species with no differences between sexes in LWR was 3.12 (SE = +/- 0.05). Average b-value in LLR was 0.823. First references on LWRs and L-50 are presented for 13 and four fish species, respectively, as well as the new maximum total lengths for eight species.
