Length-Weight and Length-Length Relationships and Condition Factor of An Endemic Fish Species (Capoeta tinca (Heckel, 1843)) Inhabiting Bayat Pond (Ankara, TÜRKİYE))

Abstract

The aim of this study is to determine the length-weight relationship, length-length relationship, and Fulton’s condition factor (K) of Capoeta tinca, which is endemic to Turkey. A total of 52 samples were obtained from Bayat Pond in 2017. The total length (TL) of the samples ranged between 20 and 34 cm. Total weights (W) of they also varied from 85 to 446g. Strong correlations were found between length and weight. In the length-weight relationship equation, a and b was found as 0.0144 and 2.9028, respectively. b value was not statistically different from 3 (t-test, P>0.05). Therefore, this species showed isometric growth in the Bayat Pond. The value of Fulton’s condition factor was 1.0485. Total length - Fork length (FL), Total Length - Standard length (SL) and Fork length - Standard length conversion equations were calculated. There was a high correlation between all length types. In this study, the length-weight relationship, length-length relationship, and Fulton's condition factor values of Capoeta tinca inhabiting Bayat Pond were determined for the first time.

Harşit Çayı’nda Yaşayan Squalius orientalis Heckel, 1847’in Kondisyon Faktörü Boy-Ağırlık ve Boy-Boy İlişkileri

“…Türle ilgili önceki çalışmalarda elde edilen boy dağılımları Tablo 5'te sunulmuştur. Boy dağılımındaki bu farklılık avcılık metodu, örnekleme zamanı ve popülasyonun yıllara göre göstermiş olduğu farklı büyüme tarzından ve habitatların ekolojik özelliklerinden kaynaklandığı düşünülmektedir (Yazıcı & Saylar, 2022).…”

“…Farklılıklara habitatların ekolojik şartları, örnekleme şekli, zamanı ve örnek sayısı, örneklerin boy ve ağırlık dağılımları gibi faktörlerin neden olduğu düşünülmektedir. Bununla birlikte balıklarda kondisyon faktörü eşeysel olgunluk durumu, beslenme seviyesi, mide doluluk oranı, yaş, eşey ve mevsime bağlı olarak değişmektedir (Williams, 2000;Yılmaz & Sakallı, 2019;Yazıcı & Saylar, 2022).…”
