This study was conducted to examine the effect of microalgal addition on n-3HUFA contents of the rotifer Brachionus plicatilis in fish mass seed production tank. Three kinds of microalgae were supplemented to 25 kl tanks where rotifers were installed. The n-3HUFA contents of rotifer immediately increased in Nannochloropsis oculata and n-3HUFA-fortified Chlorella vulgaris supplemented groups after microalgal addition in experimental tanks, but decreased in Chlorella vulgaris and no microalgae supplemented groups. It was suggested that fatty acid composition of the rotifer may reflect that of microalgae forms.
