Figure 3.

Percentages of 2-year-old mature females before and after the pathogen outbreak. The mean values for the populations in the south and north basins (error bars indicate 1 s.e.m.) were compared using the Welch t-test, since homogeneity of variance was violated. The increase in first-time spawners after the disease outbreak was not significant in the south (p = 0.122), but significant in the north basin (p = 0.045).
