Resumo: The effect of stocking density on production of Mugil platanus fingerlings in laboratory was analyzed. Five stocking densities were evaluated: 1, 3, 5, 10 and 15 mullet/L. After 28 days, the highest growth rate was reported for animals reared at the lowest stocking density (1 mullet/L). Survival rate and water quality were also higher at the lowest stocking density. Although more fingerlings were produced at 10 mullet/L, greater number of animals decreased the water quality, which was reflected in their reduced growth and survival rates. M. platanus fingerlings should be reared in commercial production at intermediate stocking densities (3-5 mullet/L) but higher water exchange rates are recommended for lower ammonia concentration

Foram testadas cinco densidades de estocagem em duplicata: 1, 3, 5, 10 e 15 tainhas/L. Os peixes foram alimentados duas vezes ao dia, sendo oferecido alimento na proporção de 10% do peso vivo de cada tanque. O melhor crescimento foi observado para os animais cultivados na menor densidade de estocagem (1 alevino/L). Observaram-se neste tratamento a melhor qualidade de água e a maior sobrevivência. Por outro lado, o maior número de animais foi produzido na densidade de 10 alevinos/L; entretanto, isto foi obtido às custas de uma menor qualidade da água, que se refletiu em uma redução no crescimento e na sobrevivência. No caso de produção comercial, os alevinos de M. platanus poderiam ser cultivados em uma densidade de estocagem entre 3 e 5 alevinos/L; contudo, a taxa de troca de água deveria ser mais elevada, para manter a concentração de amônia mais baixa do que aquela observada neste trabalhoUniversidade Estadual De Maringá2008-05-09info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttp://www.periodicos.uem.br/ojs/index.php/ActaSciBiolSci/article/view/270210.4025/actascibiolsci.v23i0.2702Acta Scientiarum.
