Abstract
Acadja is a fishing method widely practiced in the coastal lagoons of Benin. The principle of this traditional fishery is to set a dense mass of branches in shallow water, which attract the fishes from the wild. The West African “Acadja” is a kind of fish aggregator. The harvest was found variable from 7 to 20 tons of fishes, per hectare and per year. The acadja may also act as a culture system. The study presented here attempts to give evidence of the role of acadja as a potential culture system. Two types of experimental design have been compared: enclosure with acadja (named “acadja-enclos”) and enclosure without acadja used as a control. After 12 months, a biomass equivalent of 8 tons per hectare has been harvested from the acadja-enclos, equivalent to eight times that of the control system. Among the 18 species of fish harvested,
