Ethmalosa fimbriata (Bowdich) is the most abundant clupeid in the Ivorian artisanal fisheries. It represents over 60% of lagoon catches. In Aby lagoon the size at first sexual maturity is situated at 9.6 cm for male and 9.9 cm for female. The reproduction takes place twice a year during the high salinity periods from February to May and July to August. This reproduction does not affect significantly the sex-ratio, the mean of which varies from 35% to 36%, depending the period. The fecondity is very fluctuating and varies from 11000 eggs to 148000 eggs per female.
