Beschreibung:
Spawning of bonga (Ethmalosa fimbriata Bowdich) takes place in polyhalin waters (Sppt. 〉 5ppt.). Migrations of young fish were studied by the mean of length data observed in different points of the lagoon from the artisanal fishery. Bonga remain 4 months in the hatchery (6 cm), before they expand in the whole lagoon until the age of 9/10 months. After this expansion phase, the fishes come back to the spawning fields (spawning length: 14/15 cm). Postspawning fishes leave the lagoon. Between birth and spawning, bonga are not affected by salinity changes, but reproduction occurs only in waters where salinity is higher than 5ppt.
