Abstract

In this study, length-weight relationships (LWR) and Fulton’s condition factor (K) values of totally 190 Common carp, Cyprinus carpio L., 1758 specimens, captured from Tercan Dam Lake between May 2017- October 2017, were examined. Sex composition was 41.58 % (n=79) female and 58.42 % (n=111) male. Female to male sex ratio of the population was found as 1:0.71. Fork length and weight values of overall, female and male specimens ranged from 11.2-55.5 cm/30.2-2860.5 g, 11.2-55.5 cm/30.2-2860.5 g and 12.7-47.5 cm/44.6- 1846.9 g, respectively. K values varied between 1.204 and 4.008. The average value of its was calculated as 2.155±0.041 for females, 2.138±0.046 for males and 2.148±0.030 for overall. The LWR were determined W=0.0646*FL2.6613 for females, W=0.0389*FL2.8103 for males and W=0.0528*FL2.7202 for overall. The values of b was estimated as 2.66 (females); 2.81 (males); 2.72 in overall. According to b value of LWR, the growth of C.carpio was negatif allometric (b<3, P<0.005). No information currently exists on the LWR of C.carpio in the Tercan Dam Lake, Eastern Anatolia, Turkey. Therefore, this paper is an important contribution to the fisheries management applications.

Tercan Baraj Gölü 'nde Yaşayan Sazan (Cyprinus carpio L., 1758) Balığının Boy-Ağırlık İlişkisi ve Kondisyon Faktörü

Abstract

Bu çalışmada, Tercan Baraj Gölü’nden Mayıs 2017-Ekim 20017 tarihleri arasında yakalanan 190 adet sazan balığının (Cyprinus carpio L., 1758) boy-ağırlık ilişkileri ve Fulton’s kondisyon faktörü değerleri incelenmiştir. Örneklemin % 41.58 (n=79)’sını dişiler, % 58.42 (n=111)’ünü erkekler oluşturmuştur. Populasyonun dişi/erkek oranı 1:0.71 olarak bulunmuştur. Örneklerin çatal boy ve ağırlıkları sırasıyla 11.2-55.5 cm/30.2-2860.5 g, 11.2-55.5 cm/30.2-2860.5 g and 12.7-47.5 cm/44.6-1846.9 g, olarak bulunmuştur. Kondisyon faktörü değerleri 1.204-4.008. arasında değişmiştir. Ortalama kondisyon faktörü dişiler için 2.155±0.041, erkekler için 2.138±0.046 ve tüm bireyler için ise 2.148±0.030 olarak hesaplanmıştır. Boy-ağırlık ilişkileri dişilerde W= 0.0646*FL2.6613, erkeklerde W=0.0389*FL2.8103 ve tüm bireylerde W=0.0528*FL2.7202 olarak tespit edilmiştir. ''b'' değerleri dişilerde 2.66, erkeklerde 2.81 ve tüm bireylerde 2.72 olarak hesaplanmıştır. C.carpio'nun büyümesi negatiftir (b<3, P<0.005). Tercan Baraj Gölü'nde C.carpio' nun boy-ağırlık ilişkisi ve kondisyon faktörü hakkında bilgi bulunmamaktadır. Bu nedenle, bu çalışma, balıkçılık yönetimi uygulamalarına önemli bir katkı sağlayacaktır.
