Özet

Spatial and seasonal variations of silver crucian carp catch for fishing with monofilament trammel nets were investigated in Lake Eǧirdir. 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. © Central Fisheries Research Institute (CFRI) Trabzon, Turkey and Japan International Cooperation Agency (JICA).
