Age, growth and feeding of anchovy were studied for the first time from samples collected in the Benisaf Bay (west Algerian coast) during summer (spawning period) and autumn (recruitment period) 2007. Age structure and growth parameters were determined by otolith (sagitta) analyses. The von Bertalanffy growth function fitted to age-length data showed that growth was almost achieved during the first year of life. Significant growth difference was recorded between males and females. Growth parameters were for females (L∞=17,46 cm, k=0,31 per year and t0= -3,46 years) and for male (L∞=16,67 cm, k= 0,35 per year and t0= -3,26 years). The parameters of the otoliths (surface, length, weight and width) were significantly correlated with age and fish length (LT)... |
