Table 4 Measurements of larval B. polymorphus (metacercariae), recovered from A. bjoerkna, P. semilunaris and two groups of N. melanostomus. N. melanostomus of size 1 represents 0+ juvenile fish collected in August, size 2 group represents adult/subadult fish (1+ and older) collected in November in the River Morava. Length and width of fluke, primordial ovary and both testes were measured
