Effects of repeated infection of marbled crayfish juveniles using two A. astaci zoospore concentrations (7500 and 15000 zoospore/ml) on A total weight gain (total growth) B rate of weight increment (rate of growth) and C survival probability of individuals. Different letters in panel A denote significant differences, error bars represent 95% confidence intervals (CIs) around the mean. Results for total length gain and rates of length increment are presented in Suppl. material 1: S4.
