Accounting for heterogeneity in small-scale fisheries management: The Amazon case

► Little scientific and management attention is paid to the heterogeneity of tropical small-scale fisheries. ► Fisheries heterogeneity was found to be high across eight fishing communities. ► Many key community fisheries characteristics were not accounted for by management regulations. ► Management can be improved through better consideration of the heterogeneity of small-scale fisheries.
