Fishing experiments were conducted using trammel nets of different mesh sizes ranging from 60 to 160 mm in 2005. The results of this study showed the that silver crucian carp catch importantly changed among fishing areas. Hoyran sampling site of the lake gave 5.28 and 2.86 times more catch than Köprü and Sogula sampling sites, respectively. It was found a significant positive correlation between catch and water temperature variations. The silver crucian carp catch in the summer was 4.71, 2.64, and 1.48 times higher than spring, autumn and winter, respectively.
