Length-Weight, Length-Length Relationships and Condition Factor of Squalius cephalus (Linnaeus, 1758) in the Munzur River

In this study; some features were investigated such as length-weight, length-length relationships and condition factor of Squalius cephalus (Linnaeus, 1758) were collected between 2019-2021 from Munzur River. 49 were female and 59 were male; female/male ratio was found to be 1/1.20. Total length and weight ranged between 8.2-24.1 cm and 6.8-148.6 g for female; 8.9-24.3 cm and 7.3-156.8 g for male. The length-weight relationship of S. cephalus was found W = 0.0079L3,1229 (R² = 0.965) in females, W = 0.0074L3.1536 (R² = 0.971) in males and W= 0.0076L3.1407 (R² = 0.969) in all individuals. It was determined that the b value was not statistically different from 3 in female, male and all individuals (t-test; p>0.05). The growth of the S. cephalus was determined to be isometric (b=3) in the Munzur River. The relationship between total, fork and standard lengths was determined for female, male and all individuals were quite strong (P<0.001; R2>0.927). Condition factor of S. cephalus varies between 0.827-1.438 in females and 0.826-1.517 in males from Munzur River.
