| ABSTRACT In intensive hydroponic systems, such vertical and pyramidal systems, photosynthetically active radiation (PAR) and integrated (IPAR) may be intercepted by the containers and the leaf area of the plants grown in the upper strata, decreasing fruit yields and quality. The objective of this study was to evaluate the behavior of PAR and IPAR at different planting heights and the effect of geographic orientation and fruit yield and quality of strawberry produced in stair-like containers. The factors were four heights of the container (0.20, 0.50, 0.80 and 1.10 m) and two orientations (east and west). At each height and orientation of the container, PAR and IPAR, yield and fruit total soluble solids were measured. PAR and IPAR were statistically... |

| The aim of this study was to evaluate the effect of replacing animal protein with vegetable protein sources on the productive performance of Astyanax altiparanae (lambari-do-rabo-amarelo). Five experimental diets were formulated with increasing replacement levels of animal protein by vegetable protein. A total of 9000 individuals (initial mean weight 1.18 ± 0.12 g, initial mean length 2.1 ± 0.3 cm) were distributed in 20 net cages (1 m3) with a density of 450 ind. m-3. Cages were randomly placed in a pond (180 m2, 1.5 m deep, 10% water renewal per day). After 63 days of cultivation, total count and individual biometrics from 20% of each experimental unit were taken. Mean weight, total length, survival, feed conversion, biomass weight gain and proximate... |
