Figure 8. Mortality in the two-week period before (green) vs. after (orange) delousing by chemical methods (Alpha Max, Salmosan), freshwater, mechanical method (Hydrolicer, SkaMik) and thermal methods (Thermolicer, Thermolicer and Optiflush) for diploid (A) and triploid (B) fish groups. The middle line of the boxplots is the median, the upper and lower parts of the boxes are the 75- and 25-percentiles, the whiskers the highest/smallest value within the 1.5*the interquartile range, and the dots the values outside the whiskers.
