Table 2. Mean abundances of fish larvae (larvae · 100 m -3 ), results and significance level (* p < 0.05, ** p < 0.01) for two-way ANOVA performed to test whether mean abundances of fish larvae differed significantly between different months and stations. For families where ANOVA detected no significant (ns) interaction the Tukey results are given. Letters indicate significantly different means from Tukey test. d.f.: degrees of freedom. Residual d.f. 89.
