4.3. Effect of month and season on the monogenean infection
The results showed significant seasonality in the Diplozoon infection in two lakes (Anchar and Dal lakes), whereas clear seasonality was not observed in least nutrient enriched lake (Manasbal Lake). The seasonality in two lakes in our study is in conformity with the results of Yufa and Tingbao (2011) who concluded that the
monogenean species showed seasonal alterations associated with environmental changes. The abrupt increase in Diplozoon infection from winter in Anchar Lake could be due to increased duration of life of the infective larva, thereby assisting the transfer of Diplozoon
