原始语种摘要: Abstract(#br)Combined effects of different light regimes, 6L : 6D and 12L : 12D (hours light : hours dark, L:D) and algal foods of Scenedesmus quadricauda (S) and Chlorella vulgaris (C) on ephippia production and fatty acid (FA) profile of Ceriodaphnia quadrangula were investigated. The highest resting egg production, density, and specific growth rate were obtained with 6L : 6D +S; followed by 12L : 12D +S treatment. The C16 :0 varied from 16.2 to 22.16 mg/g dry weight (d.w.); C18 :1n−9 from 11.03 to 14.94 mg/g d.w; C18 :2n−6 from 9.79 to 20.24 mg/g d.w; and C18 :3n−3 from 6.98 to 16.02 mg/g d.w. The amounts of C20 :4n−6 (4.36 mg/g d.w) and C20 :5n−3 (3.35 mg/g d.w) at 6L : 6D +S were highest compared to other treatments. The maximum saturated fatty acids and monounsaturated fatty acids...
