| O potencial genético para o crescimento de qualquer espécie animal depende das condições ambientais em que são cultivados, como competição por espaço, alimentos e oxigênio. O presente experimento foi conduzido com o objetivo de avaliar o desempenho produtivo de alevinos de tricogaster (Trichogaster trichopterus), uma espécie de peixe ornamental, submetidos a diferentes densidades de estocagem e índices alimentares. Os peixes (com peso médio de 0,56 g ± 0,09 e 0,96 g ± 0,13) foram divididos em dois blocos, submetidos às densidades de 5, 10 e 15 peixes/aquário e alimentados a taxas de 3, 6 e 9% do peso vivo/dia. Os peixes foram alimentados, uma vez ao dia, com ração comercial moída e mantidos em aquários (com capacidade para 100 L) dotados de filtro... |

| ABSTRACT We aimed to evaluate the effects of Curcuma longa as growth promoter, skin pigmentation enhancer, and stress reducer in diets of Trichogaster labiosa after transport. We used five diets containing 0.0, 1.0, 5.0, 10.0, and 25.0 g kg−1 of turmeric rhizome powder. We observed quadratic effects of turmeric supplementation for feed intake, weight gain, final length, and specific growth rate. The estimated amount of turmeric that decreased these variables ranged from 15.53 to 16.39 g kg−1. Quadratic effects of supplementation of turmeric for cyan and black dorsal skin coloring indices were observed, with estimated values that increased these variables equal to 15.03 and 17.44 g kg−1, respectively. After fish transport, quadratic effects of turmeric were... |

| The objective of this work was to determine the proper levels of protein and energy in diets of Hoplias lacerdae fingerlings. The dietary crude protein (CP) and gross energy (GE) levels for fingerlings of giant trahira were evaluated in a completely randomized 4x3 factorial design with 35, 39, 43 and 47% CP and 4,100, 4,300 and 4,500 kcal kg-1 of GE, and four replicates. The survival rate was 99.22%, and a linear improvement on the performance parameters was detected after increasing diet crude protein levels. Feed conversion ratio decreased with increasing levels of dietary protein and energy in the diets. A significant interaction between crude protein and gross energy was observed over body protein and mineral matter. Body lipid has increased linearly... |
