Summary
Bu çalışmada Almus (Tokat-Türkiye) baraj gölünde yaşayan 9 balık türünün (Capoeta tinca, Leuciscus cephalus, Chondrostoma regium, Barbus plebejus, Capoeta capoeta, Oncorhynchus mykiss, Chalcalburnus chalcoides, Cyprinus carpio, Siluris glanis) boy ağırlık ilişkileri tespit edilmiştir. Balık örneklemeleri 2005-2006 yılları arasında farklı göz açıklığında (17, 25, 36, 60, 70 mm) galsama ağları kullanılarak gerçekleştirilmiştir. Örneklenen 9 türün boy-ağırlık ilişkisindeki “b” katsayısı en küçük 2.709 (C. chalcoides), en büyük 3.267 (C. regium) ve ortalama 3.065 olarak tespit edilmiştir. Boy-ağırlık arasında en yüksek (r2= 0.99) ilişki C. carpio türünde en düşük (r2= 0.91) ilişki ise C. chalcoides türünde hesaplanmıştır. Büyümenin C. tinca, L. cephalus, C. regium ve O. mykiss türlerinde pozitif allometrik, B. plebejus, C. capoeta, C. chalcoides, C. carpio ve S. glanis türlerinde ise isometrik olduğu belirlenmiştir.

Abstract
In this study, the length-weight relationships of the 9 fish species (Capoeta tinca, Leuciscus cephalus, Chondrostoma regium, Barbus plebejus, Capoeta capoeta, Oncorhynchus mykiss, Chalcalburnus chalcoides, Cyprinus carpio, Siluris glanis) living in the Almus Dam Lake (Turkey-Tokat) were determined. Sampling of these fish species were performed during the years 2005 and 2006 by utilizing gillnets with differing mesh sizes of 17, 25, 36, 60, and 70 mm. The minimum (C. chalcoides), the maximum (C. regium) and the mean “b” parameter values of the length-weight relationship among these 9 species were estimated as 2.709, 3.267 and 3.065, respectively. Growth was found to be positive allometric for C. tinca, L. cephalus, C. regium, O. mykiss and isometric for B. plebejus, C. capoeta, C. chalcoides, C. carpio and S. glanis species.
