Larvae of swimming crab were reared in 1-2 l tanks, supplied with marine rotifers cultured with several feeds: baker's yeast, baker's yeast fortified with cuttlefish liver oil, freshwater <i>Chlorella</i>, and marine micro algae <i>Nannochloropsis</i>. The fatty acid compositions of the rotifers were analyzed to evaluate their dietary value. Larval survival, growth and velocity of development were improved according to the amount of n-3 highly unsaturated fatty acids (n-3HUFA) contained in rotifers. Consequently, it was considered that the larval swimming crab demanded the n-3HUFA in feeds as essential fatty acid and enrichment of feed rotifers should be a routine technique in the seed production process of the swimming crab.
