Avaliou-se efeitos de quantidades e freqüências diárias de alimentação na sobrevivência, crescimento e conversão alimentar de pós-larvas de <em>Macrobrachium amazonicum</em>. A ração foi oferecida 1, 2, 4 e 8x/dia. As proporções alimentares foram: 10, 20, 40, 80, 160 e 320% da biomassa, proporcionadas pelas quantidades de 10, 20 e 40% nas freqüências diárias. As pós-larvas foram mantidas em tanques-rede e o peso avaliado por 20 dias. A sobrevivência sempre foi acima de 90%. Apenas a freqüência diária de alimentação afetou o crescimento. O oferecimento de alimento 4x/dia aumentou o ganho de peso (apenas na proporção de 40% da biomassa). A conversão alimentar foi afetada apenas pela freqüência diária de alimentação, sendo maior nas maiores quantidades de alimento. Esses efeitos parecem decorrer da competição alimentar e da estabilidade do alimento na água. Conclui-se que a melhor oferta de alimento seja a proporção de 40% da biomassa, dividida em 4x/dia This study investigated practical feeding strategies for survival, growth and food conversion rate in <em>Macrobrachium amazonicum</em> post-larvae. The prawns were provided with food 1, 2, 4 and 8 times a day. The food amounts were 10, 20, 40, 80, 160 and 320% of the prawns´ total weight, resulted from the amounts of 10, 20 and 40% in daily frequency. The weight gain was evaluated during the 20 days while the post-larvae were kept in net cages. Survival was always over 90%. Growth was affected only by the daily frequencies of feeding. Food offered 4 times a day increased body weight (only at the rate 40% food amount). Food conversion was affected by daily frequency of feeding and it was higher when the largest amount of food was offered. Feed competition and food stability in the water may be the reason for it. Thus, the best feeding regime should be 40% of biomass, 4 times a da
