FIGURE 5 | ANCOVA interaction effects for the relationship between gonad weight (gw) and body weight (bw) for female (A) and male (D) Salminus brasiliensis. Mean gonadal index (GI) for female (B) and male (E) S. brasiliensis by river (HA – highly altered; MA – moderately altered; LA – less altered). GI for female (C) and male (F) S. brasiliensis over time. GI was measured as the relationship between ln(gw)/ln(bw^1.25) for females and ln(gw)/ln(bw^1.07) for males.
