Abstract
Some aspects of population dynamic and the stock status of Selene dorsalis were investigated in the coastal waters of Côte d’Ivoire from March 2016 to February 2018. For this purpose, 869 fish species were collected. The range length of collected species was 7.5cm to 30.3 cm. The asymptotic length (L∞) was 32.02 cm, with a growth rate (K) of 0.56 per year. The growth performance index (Φ′) was 2.76 per year with longevity of 5.35 year. The natural mortality rate (M) was estimated at 1.16 year-1 and lower than the fishing mortality rates (F) estimated at 1.19 year-1. The current exploitation rate (0.50) was higher than E0.5 (0.38). The main losses in the stock up to 13.5 cm size was due to natural causes and after this size mortality due to fishing increased and eventually outnumbered the natural losses. The annual total stock and biomass were estimated at 10.412, 5.546 tons respectively
