Several studies about the fi shing sector have been carried on in the Amazon, however, the majority of these studies are concentrated on regions near the Amazon river bank and its delta. This work has the objective to characterize the Purus commercial fishing fleet and the fisher in three counties: Manoel Urbano and Sena Madureira in the Brazilian state of Acre (AC) and Boca do Acre, in Amazonas (AM).We estimate the fisheries
production and income. The results show that in
Manoel Urbano (AC) lake fisheries predominate
while in Sena Madureira (AC), the diversity in
fishing places are lager with fishers using lakes,
river and creeks. In Boca do Acre (AM), the largest among the three cities, the most important fishing plots are Pauini and Labrea areas. In relation to boats, Manoel Urbano fishers use only canoes with most of it motorized. In Boca do Acre, fi sheries are practiced mainly in boat. In relation to fishing trip costs the results showed that variable costs are the main costs for canoes (63% of total income) and boats (73% of total income). The analyses showed also that motorized canoes have larger productive capacity per unit of
effort (CPUE) in relation to boats.
