Some Growth Characteristics of Barbus cyclolepis Heckel, 1837 and Gobio bulgaricus Drensky, 1926 (Teleostei) Species Living in Karasu Stream (Istanbul)

Çiğdem ÇelikMüfit Özuluğ

Objective: In this study, some growth characteristics of Barbus cyclolepis Heckel, 1837 and Gobio bulgaricus Drensky, 1926 species living in Karasu Stream, were investigated.

Materials and Methods: Sampling was carried out seasonal (August 2017, November 2017, January 2018, February 2018, April 2018) via electroshock. Samplings representing each season were repeated for 3 consecutive days. Lenght, weight, age, sex distributions and ratios, age-length, age-weight, length-weight relationships, Von Bertalanffy parameters, Fulton condition factor values of the obtained B. cyclolepis and G. bulgaricus individuals were analyzed.

Results: The examined B.cyclolepis individuals are in the 0-III age groups. Standard length values are 3.5-13.5 cm; The weight values varied between 1.2232-50.8213 g. The female: male ratio was determined as 1: 0.94. In all individuals; Length-weight relationship was determined as W= 0.0253*SL2.9226. According to age, the lowest condition factor value was found in female individuals in the III age group (1.982), and the highest condition factor value was found in male individuals in the I age group (2.288). The age distribution of G. bulgaricus species varies between I-IV age groups. Standard length values are 2.5-9.6 cm; The weight values varied between 0.2989-18.3014 g. The female: male ratio was determined as 1:1.56. In all individuals; Length-weight relationship was determined as W= 0.0209* SL3.0081. According to age, the lowest condition factor value was found in male individuals in the II age group (1.950), and the highest condition factor value was found in female individuals in the IV age group (2.191).

Conclusion: As a result of this study, some growth characteristics of Barbus cyclolepis and Gobio bulgaricus species living in Karasu stream were investigated for the first time.

Karasu Deresi’nde (İstanbul) Yaşayan Barbus cyclolepis Heckel, 1837 ve Gobio bulgaricus Drensky, 1926 (Teleostei) Türlerinin Bazı Büyüme Özellikleri

Çiğdem ÇelikMüfit Özuluğ

Amaç: Bu çalışmada Karasu Deresi’nde yaşayan Barbus cyclolepis Heckel, 1837 ve Gobio bulgaricus Drensky, 1926 türlerinin bazı büyüme özellikleri mevsimsel olarak incelenmiştir. Materyal ve Yöntem: Örnekleme mevsimlik olarak (Ağustos 2017, Kasım 2017, Ocak 2018, Şubat 2018, Nisan 2018) elektroşok aracılığıyla gerçekleştirilmiştir. Her mevsimi temsil edecek örneklemeler arka arkaya 3 gün tekrarlanmıştır. Elde edilen B. cyclolepis ve G. bulgaricus bireylerinin boy, ağırlık, yaş, eşey dağılımları, yaş-boy, yaş-ağırlık, boyağırlık ilişkileri ve Fulton kondisyon faktörü değerleri incelenmiştir.

Bulgular: İncelenen B. cyclolepis bireyleri 0-III yaş gruplarındadır. Standart boy değerleri 3,5-13,5 cm; ağırlık değerleri ise 1,2232-50,8213 g arasında değişmiştir. Dişi:erkek oranı 1:0,94 olarak saptanmıştır. Tüm bireylerde; boy-ağırlık ilişkisi W= 0,0253*SL2,9226 olarak belirlenmiştir. Yaşa göre en düşük kondisyon faktörü değeri, III yaş grubunda (1,982) dişi bireylerde, en yüksek kondisyon faktörü değeri I yaş grubunda (2,288) erkek bireylerde bulunmuştur. G. bulgaricus türünün yaş dağılımı ise I-IV yaş grupları arasında değişmektedir. Standart boy değerleri 2,5-9,6 cm; ağırlık değerleri ise 0,2989-18,3014 g arasında değişmiştir. Dişi:erkek oranı 1:1,56 olarak saptanmıştır. Tüm bireylerde; boy-ağırlık ilişkisi W= 0,0209*SL3,0081 olarak belirlenmiştir. Yaşa göre en düşük kondisyon faktörü değeri, II yaş grubunda (1,950) erkek bireylerde, en yüksek kondisyon faktörü değeri IV yaş grubunda (2,191) dişi bireylerde bulunmuştur.

Sonuç: Bu çalışma sonucunda Karasu deresinde yaşayan Barbus cyclolepis ve Gobio bulgaricus türlerinin kimi büyüme özellikleri ilk defa incelenmiştir.
