The cultivation of more than one species needs to be done to improve land use efficiency. Multitrophic seafarming has been practiced in several countries and involves two important components in its development. The first is the choice of aquatic plants and animals that can be cultivated together in one cultivation area and the second is water quality management through water replacement techniques. The purpose of this study was to determine the cultivation techniques and weight gain of seaweed and aquatic animals. The cultivated seaweed was Eucheuma cotonii, while the cultivated aquatic animals were milkfish and sea cucumbers. The treatments tested were the replacement of the water in a 10-ton culture tank consisting of daily water circulation, water changes every two days and a complete turnover every 3 days. The seaweed was done in a cultivation pond equipped with water flow manipulation. The water flow manipulation was achieved by adding a water pump to rotate the water flow. The variables observed were the growth of the cultivated biota and water quality. The preliminary research results showed that the weight gain of the seaweed after 18 days reached 3 times the initial weight.
