This study was conducted to examine the supplemental effect of n-3HUFA-Chlorella to rearing water on morphogenesis of swimming crab Portunus trituberculatus (Brachyura: Portunidae) zoeas. The longer supplementation with n-3HUFA-Chlorella conduced to excess morphogenesis of megalop at the fourth zoea stage, inhibiting normal metamorphosis from zoea to megalop. The longer supplementation also induced higher carcass DHA content of forth stage zoea. These suggests that n-3HUFA-Chlorella supplementation and carcass DHA content relate high mortality occurred at the metamorphosis from zoea to megalop.
