| Abstract | ||||
| Some population parameters of the comber, Serranus cabrilla, were presented in this study. From January to December 2018, a total of 1250 samples of Serranus cabrilla (11 ≤ TL ≤ 23.9 cm, 14.34 ≤ TW ≤ 157.7 g), have been studied in the Gulf of Annaba (Eastern coasts of Algeria), based on length-frequency data. FiSAT II software was used for different analyses. The growth parameters of Von Bertalanffy are L∞ = 24.94 cm, k = 0.38 year-1 and to = -0.45 year, with a performance of growth (φʹ) of 2.37. The total (Z) and natural (M) mortality of comber in the Annaba gulf were equal to 1.41 and 0.81 year-1 respectively, while the fishing mortality was estimated to 0.60. The exploitation rate is around 0.45 and indicates that the population of comber is lightly under exploited in the study area. The length at first capture (Lc50) is equal to 12.04 cm. | ||||
