Growth and feed utilization of the shrimp Farfantepenaeus paulensis fed diets containing different marine protein sources

Five isonitrogenous and isoenergetic diets containing different protein sources (fish, squid and mussel meals and their combinations at the proportions of 40, 30 and 30% or 60, 20 and 20%) were fed for 28 days to Farfantepenaeus paulensis. Growth performance and feed utilization of shrimp fed the fi...

Description
Summary:Five isonitrogenous and isoenergetic diets containing different protein sources (fish, squid and mussel meals and their combinations at the proportions of 40, 30 and 30% or 60, 20 and 20%) were fed for 28 days to Farfantepenaeus paulensis. Growth performance and feed utilization of shrimp fed the fish meal-based diet was comparatively inferior to those fed other protein sources or their combinations. This indicates that fish meal may not be the best protein source for F. paulensis. Feeds containing a mixture of protein sources are better utilized by F. paulensis and therefore result in significantly higher growth than those containing a single protein source. Cinco dietas iso-protéicas e iso-energéticas contendo diferentes fontes de proteína marinhas (farinhas de peixe, lula e mexilhão e suas misturas nas proporções de 40, 30 e 30% ou 60, 20 e 20%) foram oferecidas durante 28 dias para o camarão Farfantepenaeus paulensis. O crescimento e a taxa de conversão alimentar dos camarões arraçoados com a dieta a base de farinha de peixe tendeu a ser inferior àqueles alimentados com as outras fontes de proteína e/ou suas combinações. Estes resultados indicam que a farinha de peixe pode não ser a melhor fonte protéica para F. paulensis. Dietas contendo uma mistura de fontes protéicas foram mais bem utilizadas por F. paulensis e, portanto, resultaram em taxas de crescimento superiores àquelas contendo uma única fonte de proteína.
