However, highly virulent strains were exclusively found in summer months especially during spawning season ( Figure 5 ) and we observed a significant correlation between maximum virulence per sampling month and diversity (Chao1 index: Spearman rank correlation: r = 0.89, p = 0.03; Shannon-Wiener Index: Spearman rank correlation: r = 0.75, p = 0.08), which was also reflected in a nearly significant correlation of maximum virulence per sampling month with temperature (Spearman rank correlation: r = 0.77, p = 0.08).
