Correlations between upper salinity tolerance limit (g kg⁻¹) and ventilation frequency at salinities of 13 g kg⁻¹ (VF₁₃, times min⁻¹) and 14 g kg⁻¹ (VF₁₄, times min⁻¹) and initial body mass (g) of grass carp. VF₁₃: r² = 0.155, p = 0.0032; VF₁₄: r² = 0.253, p = 0.003; initial mass: r² = 0.092, p = 0.026. The data are shown by the circles and the regressions are shown by the blue line.
