ABSTRACT. – This study addresses for the first time the biology of the comber, Serranus cabrilla (Linnaeus, 1758), from the eastern Algerian coast. From October 2015 to September 2016, 1063 specimens were collected each month in the Gulf of Annaba. The total length of the whole population ranged from 11.3 to 23.7 cm, and the population aged between 1 and 6 years old. The growth parameters obtained by von Bertalanffy model were: L_∞ = 24.03 cm, k = 0.22 year^–1 and t₀ = –1.67 year for males, L_∞ = 24.7 cm, k = 0.21 year^–1 and t₀ = –1.65 year for females and L_∞ = 24.91 cm, k = 0.20 year_–1 and t₀ = –1.81 year for all individuals, with a growth performance (φ’) equal to 2.10 for both sexes and 2.09 for all specimens. The relationship between total length and body mass of fish for males, females, immatures and all individuals were EW = 0.013 TL ^3.01, EW = 0.008 TL ^3.05, EW = 0.015 TL ^2.82 and EW = 0.01 TL ^2.998, respectively. The sex-ratio was estimated at 0.49:1 in favor of females and the breeding season extended from March to July. Males and females reached their first sexual maturity at 16.08 and 16.37 cm TL, respectively
