| O conhecimento da taxa ótima de alimentação para uma determinada espécie não só é importante para promover o maior crescimento e a melhor eficiência na alimentação, mas também para prevenir a deterioração de qualidade de água como resultado do excesso de alimento. O presente estudo teve como objetivo avaliar o desempenho do robalo-peva, Centropomus parallelus cultivado em tanques-rede flutuantes sob o efeito de diferentes taxas alimentares (1; 1,5; 2 e 2,5% da biomassa ao dia e a taxa controle que foi até a saciedade), em condições de cultivo no ambiente natural. Durante 40 dias, cada tratamento foi avaliado em triplicatas e foram verificados os parâmetros biológicos (sobrevivência, taxa de crescimento específico, peso e comprimentos médios finais) e... |

| Several sea bass-rearing experiments were performed from hatching trough metamorphosis. The rearing units employed were 500 1 polyester tanks, where flow rate and temperature of seawater, light and suitable food (rotifer and artemia) were controlled. Stock density ranged between 50 and 100 larvae per liter. Individuals held in tanks with internal black walls developed faster and had a greater survival rate than those in white tanks. This suggests that a better contrast between preys and background assists the larvae to see food organisms more clearly. The sea bass larvae search for food is based only in vision and not trought mechanoreceptors or chemoreceptors. It was very difficult to evaluate the light intensity (50-5000 lux) influence on feeding,... |

| ABSTRACT The objective of the present study was to characterize the scientific production regarding the factors that influence broiler chicken production, and that were published from 2000 to 2015 in journals indexed in the database of Google Scholar, Scielo, and ScienceDirect. The research was done in the Thermal Comfort Laboratory at FEAGRI- UNICAMP, and the concept of the systematic review was applied. The research criterion was initially defined (the keywords) aiming to identify and evaluate the variables that describe the experimental characteristics and the animals. The primary keywords identified were: broiler chicken from commercial strains, broiler production, rearing conditions, thermal environment, air quality, acoustic environment, light... |
