Fishing provides the main source of dietary protein and is a resilient economic activity that influences fish stocks in the Aby lagoon. It led to an initial collapse and is now in a critical situation, generating conflicts. Decision-making to control this situation requires real data. Thus, surveys on fishermen’s activity and landings were conducted to elucidate the factors of production and production in this study. The results show that the majority of national actors (80.30% of this population) are 71.08% educated. Adults aged 30 to 45 (49.67%) dominate this group of actors, most of whom are married (80.69%) and classified as occasional fishermen (49.46%). These fishermen, 49.56% of whom combine fishing with other activities, use gillnets, traps, bamboo traps, longlines, cast nets, purse seines and acadjas as fishing gear. The total fishing effort calculated for the Aby lagoon is 20,129 trips with the highest effort recorded in Adiaké (48%) and lowest in Ettuéboué (19 %). Total annual production amounted to 2,105.394 Kg highest in Assinie-Mafia (34.85 %) and lowest in Adiaké (31.72%). The total catch per unit effort is 237.80 kg/trip, highest in Assinie-Mafia (53.39 %) and lowest in Adiaké (17.90 %).
