Sex steroid levels in females at spawning streams (late-stage maturation) (ng/mL, mean ± SE).

Notes: Sex steroid levels for females at spawning streams. Females with 17,20β-DHP levels >10 ng/mL were determined to be mature, indicating that ovulation had either initiated or occurred. All fish (regardless of presence or severity of gillnet disentanglement injuries) were included in estimates for fish with/without fungal infection and coloration. In evaluating relative effects of injury and infection on reproductive hormones, severity of injury was a better predictor than fungal infection for E2 (Kruskal-Wallis: Injury: χ22,102 = 19.5, P = 0.000; Infection: χ21,102 = 8.6, P = 0.041) as well as 17,20β-DHP (Kruskal-Wallis: Injury: χ22,102 = 27.2, P = 0.000; Infection: χ21,102 = 0.9, P = 0.342).
