Caulerpa lentillifera J. Agardh belongs to the order Caulerpales, division Chlorophyta. It also called green caviar or sea grape. Since 2002, it has been transplanted from Japan to Khanh Hoa, Vietnam by the Department of Marine Botany, Institute of Oceanography. Study results showed that it can be planted using two methods: on sediment bottom or in net cage. Their productivity is directly proportional to the initial stock, but the initial stocking rate from 100 to 200g/m2 is suitable for commercial aquaculture. In ponds, their growth rate is higher than one in composite tank or in aquarium. Ponds can obtain 3.19%/day after 45 days cultured with the initial stock 100g/m2. In ponds the number of erect branches and the proportion of erect branch/algal thallus are also higher than ones in aquarium. C. lentillifera is high in minerals, vitamin A, C, and several essential unsaturated fatty acids. Analyzing results also ensured that cultured seaweed is sanitary and safe for food.
