Variations of Some Growth Characteristics and Length-Length Relationships of Sakarya Bleak (Alburnus esherichii Steindachner, 1897) in Different Habitats

In this study, some growth characteristics and relationships of Sakarya bleak inhabiting different water habitats (dam, pond and creek) in the Bilecik Province of Türkiye were examined. Sample weights ranged from 0.17 to 111.25 g. Total lengths were measured between 2.70 and 19.80 cm. According to the localities, the b values varied between 2.9469±0.07 and 3.2548±0.03. R2 values were computed between 0.850 and 0.996. The relative condition factor values were similar to each other, while the Fulton’s condition factor values ranged from 0.79±0.01 to 1.29±0.03. The length-weight (LWR) and length-length relationships (LLRs) of samples were examined. According to localities, growth type of the length - weight relationships were either isometric or positive allometric.
