Fig. 6. Effects of E2 administration on plasma zinc concentrations in
immature (A) and mature (B) female squirrelfish at days 5, 6, and 10 of the
experiment (N=2-6 fish). Results are arithmetic means ± S.E.M.
Asterisks indicate values that are significantly different from the
sham-treated control at the same sampling point (P<0.05; Dunn's
test).
