Weights of individual fish examined ranged from 1.00 to 7.34 g and
and a maximum intensity of 28 metacercariae was recovered
fromone fish. The association of various pond factors with intensity and
prevalence of infection in the juvenile fish is summarized in Table 2. In
single variable tests, depth was a significant predictor of both FZT intensity
and prevalence of infection: an increase in 1 m of pond depth was
associated with 3.01-fold increase in FZT intensity and the odds ratio associated
with a 1 m increase in pond depth was 2.19 (Table 2; Fig. 1).
Both intensity and prevalence of infection declined as fish stocking density
increased. If stocking density was greater than 200 fish m−3, intensity
of infection was only 43% of that in ponds with stocking densities
b 100 fish m−3, and similarly the odds of infection was 46% (Table 2).
