Changes in the dynamics and biology of small pelagic fisheries off Côte-d’Ivoire and Ghana: An ecological puzzle
Spatio-temporal changes in the dynamics of small pelagic fisheries in the Ghanaian-Ivoirian coastal marine ecosystem and changes in the biology of the fish are examined. The abundance of the Sardinella aurita population appears to show a transition from a depleted to a prosperous state over the last two decades. These drastic changes is puzzling as it does not appear to be in conformity with previous knowledge on the fish and fisheries of the western Gulf of Guinea ecosystem. The strengthening of minor upwelling appears to be the most likelv cause for these observed changes.
