Figure 3.
Effects of Ag+ on swim bladder inflation. The number of fish used in each group were as follows: 101 for H2O; NaNO3, 24 at 0.1 µM, 77 at 0.3 µM; AgNO3, 24 at 0.1 µM, 98 at 0.3 µM. Asterisks denote treatments significantly different from H2O (χ2 test or Fisher’s Exact Test; see Materials and Methods) and daggers denote where the AgNO3 group is significantly different from NaNO3.
