Pirarucu is one of the main fish species for the development of aquaculture in the Amazon. In this study, the optimal feeding frequency for juvenile pirarucu was assessed based on growth and feed efficiency. Juvenile pirarucu weighing ca. 80 g were fed once, twice, three ...

The Araguaia River belongs to the second largest basin in Brazil and take place in an important transition zone betweenthe Cerrado and Amazon biomes. Despite the relative richness of ichthyofauna, the greatest challenge of artisanal fisheries is the widespread lack of landing informatio...

This article summarizes these recent findings and envisions how these are impacting the production sector in the short and medium terms. Recent studies in Brazil have addressed the main challenges faced by commercial producers of pirarucu, including breeding, larval rearing, grow-out, feedin...

The present work had as objective to evaluate the effect of the harvest delay in the contamination of corn grains with fumonisins and the incidence of kernel rot.

This technique enhanced land use efficiency and allows forage production for cattle during dry season and straw to no till system.

O presente trabalho avaliou a eficácia da formalina e do triclorfon na redução dos estágios de desenvolvimento de Dawestrema sp. (Monogenea) em pirarucus oriundos de tanques-rede.

Intercropping corn and palisade grass is a technique to increase straw production, soil C contents, nutrient cycling and crop yield. However, concerns arise from nitrogen (N) uptake by the intercropping crop causing reduction in the yield of the corn. Our objective was to evaluate&...

The aim of this study was to evaluate the impacts of metazoan parasites on hematological and biochemical parameters and relative condition factor of tambaqui (Colossoma macropomum) farmed in northern Brazil. A total of 32 juvenile fish were captured from a commercial fish farm loca...
