Association silver crucian carp (Carassius gibelio BLOCH, 1782) in the Egirdir Lake belong some physico-chemical properties and spectral properties of living areas by remote sensing

In this study, the dominant species in Lake Egirdir, C. gibelio (Bloch, 1782) water quality parameters and spectral characteristics were investigated seasonally. 957 C. gibelio were sampled between November 2009 and October 2010 from 4 different stations. C. gibelio samples captured with trammel nets of mesh sizes 30, 40, 45, 50, 60 mm from all stations. Prey compositions for the nets and stations, identified as an individual, rational and gravity. During the research, the most C. gibelio samples captured with trammel nets of mesh sizes 40, 45, 50 mm from region Eğirdir.The all water samples were analyzed as seasonal. All parameters were measured for all stations following, water temprature 12- 16 °C, pH 8- 8.95, turbidity from 1- 2,31 NTU, chlorophyll-a concentration from 0,267- 1,622, dissolved oxygen 6.86- 11.37 mg/l, suspended matter 25- 32,1 mg/l. The Lake Egirdir was classified oligotrophic structured, according to the results of the chlorophyll-a analysis.Spectral measurements were made with a spectroradiometer (ASD Fieldspec (UV/VNIR)). Chlorophyll-a and reflectance values in the summer, all stations (except Hoyran) is the highest value and efficiency of fishing that have been identified in parallel.
