Abstract
This study analyzes the biometric and allometric growth characteristics of bighead carp (Hypophthalmichthys molitrix Valenciennes, 1844), Chinoz new strain. A total of 31 fish specimens were examined, including total length (TL), standard length (SL), and body weight (Q). The mean TL, SL, and weight were 59.1 cm, 50.3 cm, and 2.34 kg, respectively. The coefficient of variation showed low variability in length parameters (CV < 6%) and higher variability in weight (CV ≈ 16%). The length–weight relationship indicated negative allometric growth (b < 3). Fulton’s condition factor ranged from 1.1 to 1.3, reflecting satisfactory physiological condition. The results suggest that the Chinoz strain is promising for aquaculture applications.
