Gerlotto, F.
Ethmalosa growth curves (calculated by the least squares method) were determined from weekly samplings in Ebrié Lagoon. In order to obtain more accurate results than with a modal decomposition, the author used directly the modal values of the samples. One-year-old ethmalosa is about 15 cm long (fork length). For older fish, growth data seem to be disturbed by migrations: fish measuring >25 cm do not appear in the lagoon. Ethmalosa would spend the first year of its life in the lagoon, where it hatches and reproduces, and would migrate to the sea during its second year.
