THE GROWTH AND MORTALITY RATES OF SILVER CRUCIAN CARP (CARASSIUS GIBELIO BLOCH, 1982) IN SEYHAN DAM LAKE (SOUTHEASTERN MEDITERRANEAN REGION: ADANA, TURKEY)

In this study, growth parameters of the non-native Silver Crucian Carp (Carassius gibelio Bloch 1782) in the Seyhan Dam Lake were investigated between June 2013 and May 2014. The length ranged from 14.5 - 32.7 cm, weight varied between of 52 -607.46 g while age composition changed from 0+ -V. the group. The length-weight relationship was W=0.0107xL30095 (R2=0.9391) for females. It was determined that feature positive alio metric growth for growth females, von Bertalanffy growth constants in length and weight were as L∞ = 36.60 cm, W∞ = 835.475 g, K = 0.320 year-1 and t0 = - 0.2986 year. Natural mortality rate M = 0.74 year-1, total mortality rate Z = 0.77 year-1, fishing mortality rate F = 0.03 year-1 and exploitation rate E = 0.04 year'1 was estimated. Silvery Crucian Carp in Seyhan Dam Lake have proliferated excessively and has already invaded our respective reservoir completely.
