ResumoA importância da pesca na unidade familiar de produção (UFP) e a delimitação dos fatores que a influenciam constituem o hiato na caracterização da atividade em regiões da Amazônia sob iminência de impactos de grandes projetos. Este estudo avaliou a dinâmica e a importância da pesca em UFP de comunidades ribeirinhas à jusante da cachoeira do Teotônio (rio Madeira) e a influência na composição e abundância das espécies capturadas, de fatores ambientais, distância dos mercados e destinação da captura. ) e padrões entre as comunidades que refetem ambos os fatores ambientais, distância do pescado consumidor e destino da captura. AbstractThe fisheries importance in the family unit of production and the identification of factors that influence it, make up the gap in the characterization of the activity in the Amazon region under the impendence of large projects impacts. This study evaluated and compared the dynamics and the importance of fishing in the family unit in riverside communities downstream of Santo Antonio Dam (Madeira River) and, the influence of environmental, isolation and fishing destination in the composition and abundance of the catch. Between August/2009 and July/2010 (pre-dam period), 23 families recorded daily information about the activity to analyze the total catch, monthly and specific fish consumed and marketed and fishing effort. The results show the importance of family fishing (average production: 2.403±2.261kg.family.year ) and that differences between communities are related to both destination, isolation and environmental factors.
