These data were collected by ULM flight during low tides and different environmental conditions (day of the week, sea level during low tide, weather, time of the day, month, etc.). Assessment was done by photo-analysis. Fishermen were divided in different categories according to gear and targeted species : onshore gathering (targets octopus and shellfish), swimming fishers (with or without boat -  illegal inside the lagoon), spearfishing (illegal inside the lagoon), netfishing (targets demersal reef associated species, illegal if not professional and performed on healthy coral), traditional netfishing (targets small pelagic species), angling (targets demersal reef associated species).
