Abstract

This study is the first that deals with the stock status of the bogue Boops boops (Linnaeus, 1758) in the Eastern Algerian coast (Western Mediterranean). It aims is to estimate the important parameters needed to evaluate the dynamics of the stock of this species which is economically important resource in Algeria. The FiSAT II software has been used for data analysis. The total length and weight of the fishes sampled ranged from 10.1 to 30.9 cm and from 13.47 to 268.15 g, respectively. The longevity has been estimated at 5 years. The parameters of von Bertalanffy growth curve were L∞ = 32.03 cm, K = 0.28 yr-1, to = -1.13 years and ɸ' = 2.45. The length-weight relationships was described by parameters a = 0.016 and b = 2.815, reflecting a trend towards negative allometric growth. The total mortality (Z), natural (M) and fishing (F) mortalities were 1.03, 0.37 and 0.66 yr-1, respectively. The current exploitation rate (E) of the species was 0.64. The relative yield per recruit analysis (Y'/R) from the Beverton-Holt showed that the current level of exploitation is significantly higher than Emax and E0.5 (0.54 and 0.32 respectively), indicating that the population is overexploited and suffers from fishing pressure. For sustainable management of this resource, the current exploitation rate should be reduced by 50%.
