Fig. 4. Comparisons of liver-somatic index (LSI) in sham-injected (black bars) and E₂-treated (white bars) immature (A) and mature (B) female squirrelfish. Fish were injected on days 0, 2 and 4, and sampled on days 5, 6 and 10 of the experiment. Results are arithmetic means ± S.E.M. (N=2-7 fish). Asterisks indicate values that are significantly different from the sham-treated control at the same sampling point (P<0.05; Dunn's test).
