| 内容記述 | From points of both water quality management by algal nutrient absorption and a good live food of rotifer, the role of Nannochloropsis oculata supplied to larval rearing water was examined by a larval rearing experiment in this study. Larvae of Japanese red sea bream, Pagrus major, were reared being fed rotifers and subsequently an artificial diet during the thirty-day experimental period. In the four test tanks (100-L capacity) each with 1,000 Japanese red sea bream larvae in addition to the rotifers, N. oculata was maintained at a density of 5-10×10 5 cells/mL while in the four control tanks, no N. oculata supplemented, but all the other experimental conditions were the same as the test tanks. At the end of the experiment, the concentrations of inorganic nitrogen (NH4-N, NO2-N, and NO3-N) and inorganic phosphate (PO4-P) in the control tanks were 1.5-2.0 times higher than those in the test tanks. While, the number of rotifers with eggs in the test tanks was remarkably higher in comparison with that in the control tanks. Moreover, rotifers in the test tanks contained much more eicosapentaenoic acid (EPA) and n-3 highly unsaturated fatty acid (n-3 HUFA), so that their nutrient value is concluded as higher than that in the control tanks. From the results of this experiment, supplementation with N. oculata into the rearing water is concluded to produce beneficial effects on maintaining water quality and also enhancing the nutrient quality of the rotifers. | |||||
