Abstract
Reared in fertilized basins, Eucyclops serrulatus appeared to be able to biosynthesize 22:6 omega 3 from dietary 18:3 omega 3. The developme nt of zooplanktonic biomass, strongly dominated by Eucyclops, coincide d with the occurrence of a Chlorophycean bloom. Zooplankton phospholip ids were rich in 22:603 omega (14.5-25.9% of total fatty acids), while this fatty acid was lacking in grazed Chlorophyceae. On the other han d, Chlorophyceae contained high proportions of 18:3 omega 3. This last fatty acid was possibly bioconverted into 22:6 omega 3 and incorporat ed in the phospholipids of E.serrulatus.
