ABSTRACT The fungal genus Curvularia is associated with a number of diseases in plants, commonly producing foliar spots in forage grasses. The objective of this study was to characterize the morphological and molecular diversity of the isolates of Curvularia sp. associated with Andropogon seeds, and to assess both their capacity to transmit disease and the pathogenicity of this fungus to crop. Ten isolates of Curvularia sp. were sourced from Andropogon seeds from agricultural producing regions in the Brazilian states Tocantins and Pará. Morphological characterization was achieved by observing fungus colonies and conidia and molecular characterization by DNA extraction and amplification with sequence-specific primers. The disease transmission was evaluated...

ABSTRACT: The aim of this study was to determine the most adequate stocking density for tambatinga during the initial grow-out phase in net pens, considering fish growth, health, and financial aspects. Three stocking densities (400, 500, and 600 fish m-3) were evaluated for 60 days in a completely randomized design (n=4). There were no significant differences among the stocking densities for growth performance parameters, but yield was higher in the density of 600 fish m-3 (3,909.43±397.79kg m-3) compared to 400 fish m-3 (2,656.43±665.45kg m-3). Glucose, hematocrit, and total plasma proteins levels did not differ among treatments. The production was economically feasible for the three stocking densities. However, the density of 600 fish m-3 showed the...
