Two-sample t-test analysis results comparing rearing treatments within a maturation category.

Results from two-sample t-tests of juvenile male steelhead sampled at Winthrop National Fish Hatchery in release years 2011–2015 comparing morphological and physiological measures between rearing treatments within a maturation category. P-values < 0.05 were considered statistically significant. Abbreviations and units of measure are as follows: fork length (mm); body weight (g); gill Na+/K+ ATPase activity (μmol ADP · mg protein-1 · hr-1); pituitary follicle stimulating hormone beta-subunit (fshb) and luteinizing hormone beta-subunit (lhb), testis anti-Mullerian hormone (amh) and insulin-like growth factor-3 (igf3) (relative mRNA expression); gonadosomatic index (GSI; %); plasma 11-ketotestosterone (11KT; ng/ml). Results for fshb, lhb, amh, igf3, GSI, and plasma 11KT for all years combined are contained in Table 4.
