| 摘 要： | INTRODUCTION Aquaculture, one of fastest-growing food in-dustries, has increased worldwide at an average rate of 9.2% per year since 1970, compared with only 1.4% for capture fisheries and 2.8% for terrestrial farmed meat production system (FAO, 2002). Aquaculture has become the most advanced among agricultural fields. Simultaneously, due to intensive farming and lack of controlling guidelines, aquacul-ture’s impact on the environment has become of in-creasing concern. Excessive nutrie…

| Abstract: | Effects of dietary supplementation with fructooligosaccharides on the excretion of nitrogen and phosphorus in Miichthys miiuy fries were investigated. Nine hundred Miichthys miiuy fries were divided into 3 groups, each with triplicates. The basal diet and the basal diet supplemented with carnitine groups were considered as the negative and positive controls respectively.Results showed that the nitrogen concentration in excreted feces decreased significantly in fries fed the diet supplementation with 1000× 10-6 fructooligosaccharides and 200×10-6 carnitine (P＜0.05). The ammonic-nitrogen concentration decreased significantly in the carnitine group only (P＜0.05), indicating the decreasing tendency caused by the supplementation with fructooligosaccharides. Supplementation with both did not have significant effects on the concentration of phosphorus in feces ofMiichthys miiuy fries. |
