| Abstract: | In this study we perform an ecological analysis of the resources use in the diet of the ribeirinho populations of the Barcelos municipality, Rio Negro, Amazonas, Brazil. Data on food composition, seasonality, and origin
took place during three field trips between 1999 and 2000. Data were gathered based on structured interviews and observations
from a total of 320 meals of 114 randomly selected families and 164 fishing trips. The staple food of the studied populations
is based on fish and manioc, although the food niche amplitude can vary according to the factors such as the access to imported
food items, resources seasonality, and socio-economic conditions. The migration to urban centers along with the changes in
subsistence activities (reduction of small-scale agriculture and specialization in commercial fishing) may result in changes
in the food habits of ribeirinho populations from Rio Negro.
