The recovery of total deuterated fatty acids
(DFAs) in female C. finmarchicus from the North Atlantic
varied from 41.2 to 83.6 ng (mean values, n ¼ 2) in the
eight groups analysed (Table I). The oil sac of copepods
were pink after the 24 h incubation indicating that the
liposomes containing Nile Red stain had been ingested
and incorporated into the somatic lipid reserves.
