Description Phytoplankton cultures of Nanochloropsis oculata, Isochrysis galbana, Pavlova viridis and Dicrateria inornata, were scaled
up and analysed for fatty acids. I. galbana proved to be the richest source of docosahexaenoic acid (DHA). P. viridis and
D. inornata are rich in eicosapentaenoic acid (EPA). N. oculata is rich in EPA and arachidonic acid (ARA). When rotifers
were enriched with I. galbana and analysed for fatty acids at specific time intervals, DHA content increased till 30 h with a
maximum DHA level of 1.13% obtained in enriched rotifers. Subsequently, development of enriched emulsions using
sardine oil (90%) and fish roe (10%) as the major ingredients yielded a DHA content of 39% and EPA content of 17% and
was used to enrich rotifers. The resultant enrichment level was 8.76% DHA and 2.35% EPA at six hours after which, a
decline in the polyunsaturated fatty acid (PUFA) content was observed. The enrichment formulation holds promise as an
import substitute.
