Table 1. Morphological parameters of male and female zebrafish following chronic waterborne exposure (9 months) to tributyltin (TBT).

Values are mean±SEM (n = 15); CF and HSI are the condition factor and hepatosomatic index, respectively; **p<0.05 and *<0.1 (compared to solvent control; one-way ANOVA followed by Dunnett's test)
