ResumoThe fishery management developed at the Mamiraua Sustainable Development Reserve was adopted in Santo Antonio do Ica as an initiative of the Executive Secretariat of Fisheries and Aquaculture of the State Secretariat of Rural Production of Amazonas state, to stimulate the productive vocation of the municipality in the exploitation of fishery resources and take advantage of its strategic position in the triple border region between Peru, Colombia and Brazil, where the fish trade is remarkable. The fishery and commercialization monitoring data were collected in the years of 2012, 2013 and 2014. The analyzes used descriptive statistics techniques, proposition of models to describe the length-weight ratio of pirarucu (Arapaima gigas) and tambaqui (Colossoma macropomum), simple linear regression to describe the increase in the quantity of pirarucu each year, the determination of the billing from the product between quantity (kg) and price (R $) of marketing for each species and the income generated from the division of the billing among the fishermen involved in the management. 25 communities and 142 lakes with management potential were georeferenced, but only 9 were used due to environmental and logistic factors that limited the catches. The increase in pirarucu quantitative and density was observed in all monitored environments, as well as the mean total length and total mean weight of the captured individuals. The study of the pirarucu gonadal stages showed that the largest and heaviest individuals tend to be in the last three stages of the gonadal stages during the period of expenditure. The catches of pirarucu 50,336 kg in 2012, 34,657 kg in 2013 and 46,800 kg in 2014; and for tambaqui, 1,882 kg in 2013 and 2,542 kg in 2014. In 2014 were produced 390 kg of aruana (Osteoglossum bicirrhosum), 119 kg of surubim (Pseudoplatystoma spp.), 4,008 kg of pirapitinga (Piaractus brachypomus) and 9,450 kg of jaraqui (Semaprochilodus spp.). The commercialization on these three years of management resulted in an estimated total revenue of R$ 607,667.50, benefiting 85 fishermen and 763 families. The results obtained demonstrate the efficiency of management in conservation of the fishery resource.
