Based on field research, observations, and interview, this article aims to describe the value chain of fish farming products in the Ébrié lagoon. It poses the problem of its lack of knowledge which undermines the good development of this sector. The article shows that this value chain is driven by various actors. A first group composed of the producer (fish farmer), distributor, wholesaler, retailer and consumer. These are the key players in the chain and perform the functions directly linked to the fish farming activity. In addition, they are supported by another group of actors (supervisory and extension structure, suppliers of inputs and equipment, scientific research, financial institutions). These two groups of actors work closely together for the proper functioning of the fish value chain in the Ébrié lagoon.
