Özet

In this research, the water quality parameters and spectral characteristics of C. gibelio (Bloch, 1782) living as a dominant species in Lake Egirdir were seasonally examined. 975 C. gibelio individuals were caught from 4 different stations between November 2009 and October 2010. C. gibelio was fished with trammel nets with 30, 40, 45, 50, 60 mm sized meshes. The catch compositions and productivities of trammel nets and stations were determined individually and in terms of proportion and weight. During the study, the highest number of individuals was fished by nets with 40, 45, 50 mm sized meshes in Egirdir (38.14%) region. The water samples taken from the stations seasonally were analyzed. As a result of these analyses, water temperature at the stations was measured to vary between 12-16 C, pH between 8-8.95, turbidity between 1-2.31 NTU, chlorophyll -a concentration between 0.267-1.622 mg/1, dissolved oxygen between 6.86 -11.37 mg/1, and suspended matter between 25-32.1 mg/l. It was determined according to the chlorophyll -a values that Lake Egirdir has an oligotrophic structure. Spectral measurements were carried out with a spectroradiometer (ASD Fieldspec (UV/VNIR)). It was identified that the chlorophyll -a and reflection values were at the highest values at all stations (except for Hoyran) during summer and fishing yield was parallel with this.
