<![CDATA[Gouramy (Osphronemus gouramy) is a superior type of freshwater fish that has important economic value and promising business prospects. This fish belongs to the type of plant-eating fish (Herbivores) and also has additional respiratory equipment so that gourami can live in low oxygen conditions, but gourami has the disadvantage of relatively slow growth. Feed is one of the external factors that influence fish growth, besides that feed also contributes greatly to 60-70% of production costs. Aquatic plants (Wolffia arhizza) have quite good nutritional components because these plants contain protein accompanied by essential amino acids. This study aims to determine the effect of wolffia plants (Wolffia arhizza) on growth, as well as to determine the conversion value and efficiency of gourami feed, using an experimental method using a Complete Randomized Design consisting of 3 treatments, Treatment A (10% Wolffia plants) B (3% commercial feed) C (Combination feed) and 3 repeats. The results of this study showed that treatment A gave the best value where PP: 2.94 cm, PB: 4.99 gr, and SGR: 4.95%. As for feed quality, the C treatment gave the best EP: 3.77%, and FCR: 1.42 also the survival showed that the C treatment gave the highest value of SR: 0.80%.]]>
