Abstract
Fatty acid profiles of Moina macrocopa enriched with lipids from inexpensive squid or canola oil were compared with profiles of Moina enriched with a commercial enrichment diet, A1 DHA Selco® (ADS). Arachidonic acid (AA) significantly increased from <0.01 to 0.28 mg/g body weight in Moina enriched with ADS at 1 g/l for 12 h and to 0.38 mg/g in Moina enriched in 2 g/l canola oil for 12 h. The highest increase in eicosapentaenoic acid (EPA; from 0.15 to 0.38 mg/g) was obtained when Moina were enriched in 1 g/l ADS for 12 h. The highest increases in docosahexaenoic acid (DHA; originally <0.01) were obtained in Moina enriched in 1 g/l ADS for 12 h (increased to 0.09) or in 2 g/l ADS for 24 h (rose to 0.8 mg/g). The AA:EPA ratio was highest in Moina treated with 2 g/l canola oil for 12 h or 2 g/l squid oil for 24 h. The AA:DHA ratio was highest in Moina enriched with 2 g/l canola oil for 12 h while the DHA:EPA ratio was highest in Moina enriched with 2 g/l squid oil for 24 h.
