Resumo: | The aim of this study was to evaluate the nutritive value of free-floating aquatic macrophytes, Eichhornia crassipes (Mart.) Solms (Pontederiaceae), Pistia stratiotes (L.) (Araceae) and Salvinia molesta (Mitchell) (Salviniaceae) used in a Nile tilapia (Oreochromis niloticus) waste treatment, and these species biomass potential uses. The vegetal biomass samples were collected from 0.25 m² floating squares and divided in aerial and submerse parts, to determine the concentrations of cell wall fraction, soluble carbohydrates, polyphenols, lipids, crude protein and total phosphorus. The higher nutritive value was observed in E. crassipes and S. molesta aerial parts, and in P. stratiotes total biomass, due to their lower cell wall fraction mean rates (60.7; 64.2 and 56.9 % dry mass, respectively) and to the higher rates of: crude protein (10.1; 9.1 and 8.8 % dry mass, respectively), soluble carbohydrates (26.6; 18.7 and 12.4 mg.g-1 dry mass, respectively) and lipids (7.6; 4.5 and 4.4% dry mass, respectively). It may be concluded that P. stratiotes total biomass, and E. crassipes and S. molesta aerial biomass have nutritive values with potential use for ruminant feeding or as ration ingredients. |

Solms (Pontederiaceae), Pistia stratiotes (L.) (Araceae) e Salvinia molesta (Mitchell) (Salviniaceae), utilizadas em um sistema de tratamento de efluentes de tilápia do Nilo (Oreochromis niloticus), e inferir sobre o potencial de aproveitamento da biomassa dessas espécies. As amostras de biomassa vegetal foram obtidas através de um quadrado de 0,25m2 de área e separadas em partes aérea e submersa para a determinação dos teores de fração de parede celular, carboidratos solúveis, polifenóis, lipídios, proteína bruta e fósforo total. O maior valor nutritivo foi observado na parte aérea de E. crassipes e S. molesta e na biomassa total de P. stratiotes devido aos menores valores médios de fração de parede celular (60,7; 64,2 e 56,9 % PS, respectivamente) e aos teores mais elevados de proteína bruta (10,1; 9,1 e 8,8% PS, respectivamente), carboidratos solúveis (26,16; 18,7 e 12,4 mg.g-1 PS, respectivamente) e lipídios (7,6; 4,5 e 4,4 % PS, respectivamente). Conclui-se que a biomassa total de P. stratiotes e a biomassa aérea de E. crassipes e S. molesta têm valor nutritivo com potencial para uso na alimentação de ruminantes ou na formulação de rações.Universidade Estadual De Maringá2008-05-13info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttp://www.periodicos.uem.br/ojs/index.php/ActaSciBiolSci/article/view/235310.4025/actascibiolsci.v24i0.2353Acta Scientiarum.
