The data were tested for homogeneity of variances using Levene’s test. Where the variances were homogeneous, we used one-way analysis of variance and multiple comparisons with Tukey’s honestly significant difference (HSD) test to test for differences in Chattonella biological parameters among strains. Data not showing homogeneous variances were log-transformed, and a Levene’s test was performed once again. When the variances were not homogeneous even after log-transformation, we used the Dunnet T3 test.
To explore the parameters influencing the ichthyotoxicity of Chattonella, we calculated the Spearman’s rank correlation coefficients (ρ) between moribundity rate and Chattonella parameters of cell density, cell size, O₂^•− level, and contents of sugar and each fatty acid.
All analyses were performed with IBM SPSS Statistics Desktop Version 19.0 for Windows (IBM Japan, Tokyo, Japan) using a significance level of p < 0.05.
