This situation is aggravated by the increasing pressures of urban expansion in the lagoon areas. The Ebrié lagoon in Côte d'Ivoire is affected by the development of the city of Abidjan and provides a good example of this expansion. Improved production for lagoon areas is consequently drawing increasing interest. The adoption of acadja-enclos and pen production systems in the Ivorian lagoons reflect this development. Pen culture is essentially based on the intensive culture of catfish and requires private investment, but acadja-enclos systems are extensive, village-based farming systems. The problems of competition (for space and resources) between the acadja-enclos culture system and capture fisheries are discussed, as well as the introduction of acadja-enclos into villages and their economic effiency.
