Summary 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 S alto S antiago R eservoir, I guaçu R iver B asin, B razil. 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 LWR s and L 50 are presented for 13 and four fish species, respectively, as well as the new maximum total lengths for eight species.
