Resumo: The alginic acid is extracted from seaweed and when used in fish ration may induce immunomodulatory and immunostimulants responses. This study aimed to evaluate the effect of alginic acid incorporated in the ration on performance and handling of juvenile Nile tilapia, Oreochromis niloticus. The first phase of the experiment occurred in two excavated ponds earth. 57,000 juveniles were used for Nile tilapia, local strains with the average weight of 14 grams. The juvenile Nile tilapia received the experimental diet treated with ergosan at a dose of 1% of the diet. The survival rate of fish and feed conversion in the experimental Nile tilapia was higher than the control Nile tilapia. In the second stage 54,126 juveniles with average weight 40.63 grams, were used. These fish were transferred to 16 fish cages. There were no significant differences in mortality rate between treatments. The highest mortality occurred between the third and seventh days after the handling. The data confirm that the transfer of juvenile Nile tilapia in the ponds to fish cages is a strong stressor.

Este trabalho teve o objetivo de avaliar o efeito dos alginatos incorporado na ração sobre o desempenho produtivo e manejo de juvenis de tilápia do Nilo, Oreochromis niloticus. A primeira fase do experimento ocorreu em dois viveiros escavados de terra. Foram utilizados 57.000 juvenis de tilápia do Nilo, variedade local com peso médio de 14 gramas. Os Juvenis do viveiro experimental receberam ração tratada com ergosan na dose de 1% da dieta. A taxa de sobrevivência dos peixes e a conversão alimentar dos peixes alojados no viveiro experimental foi superior ao daqueles alojados no viveiro controle. Na segunda fase foram utilizados 54.126 juvenis de 40,63 gramas. Estes peixes foram transferidos para 16 tanques-rede. Não houve diferenças significativas de taxa de mortalidade dos peixes entre os tratamentos. A maior mortalidade ocorreu entre o terceiro e sétimo dias após o manejo. Os dados confirmam que a transferência de juvenis de tilápia do Nilo de viveiros de terra para tanques-rede é um agente estressor.UEL2011-07-12info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://ojs.uel.br/revistas/uel/index.php/semagrarias/article/view/293410.5433/1679-0359.2011v32n2p771Semina: Ciências Agrárias; Vol. 32 No. 2 (2011); 771-780Semina: Ciências Agrárias; v. 32 n. 2 (2011); 771-7801679-03591676-546Xreponame:Semina.
