Some of the biological features of the Brond-snout (Chondrostoma regium, Heckel, 1843) living in Lake Ladik (Samsun, Turkey)

Ladik Gölünden Ocak 2010-Mart 2010 tarihleri arasında yakalanan 164 adet kababurun balığı, Chondrostoma regium (Heckel, 1843) bireyinin yaş ve eşey kompozisyonu, boy ve ağırlık dağılımları, yaş, boy, ağırlık ilişkileri ve kondisyon faktörü gibi bazı biyolojik özellikleri incelendi. Yaş tayini pullardan yapıldı ve balıkların yaşlarının 2 ile 5 arasında değiştiği belirlendi. Örneklerin total boy ve ağırlıkları sırasıyla 16,5-25,4 cm ve 40,04-192,42 g arasındaydı. Eşey oranı (D/E) 1/0,29 olarak tespit edildi. Tüm örnekler için von Bertalanffy büyüme denklemi parametreleri L∞ = 28,15 cm, W∞ = 254,16 g, k = 0,30 yıl-1 ve t0 = -1,23 yıl ve büyüme performans indeks değeri (Ø') 2,38 olarak hesaplandı. Boy-ağırlık ilişkisi W = 0,0029 TB3.41 şeklinde elde edildi. Ölçülen farklı boy uzunlukları arasında kuvvetli ilişkiler belirlendi (p 0,98). Fultonun kondisyon faktörü değeri tüm bireyler için 1,01±0,09 olarak tespit edildi.

Ladik Gölü (Samsun, Türkiye) nde yaşayan Kababurun balığı (Chondrostoma regium, Heckel, 1843) un bazı biyolojik özellikleri

This study investigates the biological features of 164 brond-snout Chondrostoma regium (Heckel, 1843) samples caught in Lake Ladik between January and March 2010 such as age and sex composition, length and weight distribution, length, age and weight relations and condition factors. The age was determined from the scales and the ages of the fishes were found to change between 2 and 5 years. The range of the total lengths and the weight of the samples were found to be 16.5-25.4 cm and 40.04-192.42 g respectively. The sex ratio (F/M) was found to be 1/0.29. The parameters of von Bertalanffy growth equations were L∞ = 28.15 cm, W∞ = 254.16 g, k = 0.30 year -1 and t0 = -1.23 year and the growth performance index value (Ø') was found to be 2.38. The length- weight relation was found to be W = 0.0029 TL3.41. There were strong relations among different lengths (p 0.98). Fulton s condition factor was found to be 1.01±0.09.
