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