Estimation of Some Population Parameters of Squalius cephalus (Linnaeus 1758) in Tabakane Stream (Ordu-Turkey)
The purpose of this study is to estimate some population parameters such as length-length and length-weight relationships and condition factor of Squalius cephalus individuals living in Tabakane Stream (Ordu-Turkey). A total of 326 S. cephalus individuals were sampled from Tabakane Stream, located i...

| description | The purpose of this study is to estimate some population parameters such as length-length and length-weight relationships and condition factor of Squalius cephalus individuals living in Tabakane Stream (Ordu-Turkey). A total of 326 S. cephalus individuals were sampled from Tabakane Stream, located in Ünye district in the Ordu province, by using an electroshocker. It was determined that the mean total, fork and standard lengths of the fish samples were 7.58±0.143 cm, 7.06±0.133 cm, and 6.30±0.121 cm, respectively, and their average weight was 6.05±0.322 g. The length-weight relationship of the species was calculated as W=0.0088TL3.0648 R²=0.993. As a result of our analyzes, it was determined that the S. cephalus population in Tabakane Stream showed a positive allometric growth. In the present study, it was determined that the 95% confidence interval of the b value in the length-weight relationship equation was between 3.0566-3.0678 and there was a strong relationship between body weight and total length. Relationship equations between total, fork and standard lengths were calculated as TL=1.0724FL+0.0086 (r2=0.9978), TL=1.1763SL+0.167 (r2=0.9972), and FL=1.0961SL+0.1529 (r2=0.9979) and it was determined that there are strong relationships between standard, fork and total length measurements of S. cephalus individuals living in Tabakane Stream. It was determined that the condition factor values of S. cephalus ranged between 0.73971 and 1.27570. The average condition factor was 0.99831±0.005. There is no previous study on the population of S. cephalus living in Tabakane Stream. In this study, the condition factor, length-weight and length-length relationships of S. cephalus in this habitat were reported for the first time. |
