Fishery sector viability is usually considered as the combined viability of ecological, technical, social and/or economic subsystems considered as related subparts. This study examines this global viability at a lower level, i.e., as a result of the combination of idiosyncratic traits and activities of heterogeneous agents at the individual level. A multi-agent simulation model of the small-scale fishery sector in Senegal is presented to explore this approach. The aim of the study is to formalize diverse interaction sets between agents at the near individual level (communities) and evaluate their effect on the overall function and possible coordination of the fishery sector. Diverse sets of fishermen, traders, boats, trucks, consumers, fishing zones, markets, landing sites and fish products are formalized based on observations reported from the real sector. The model produces contrasted patterns and histories from one place (port, market) to another. Simulations show that at the integrated level, the fishery system may reach a homeostatic state by itself, where production, wealth, working population size and activity are stable and optimally organized (four indicators are presented in this respect). The homeostatic, steady regime of the simulated system can be deteriorated (e.g., when removing the entry/exit of working communities). The overall viability obtained by simulation is discussed. The role of self-adaptation, diversity, and history in the synchronization and good function of the integrated fishery system is highlighted.
