Seaweed is an abundant biological resource in Indonesian waters and has complete nutrients, so its utilization is very diverse. This study aims to determine the nutrient content of four seaweeds Gracilaria sp., Palmaria sp., Sargassum sp., Ulva sp.; and evaluate the digestibility in Osteochilus hasseltii . Seaweeds were taken at Pulang Sawal coast, Special Region of Yogyakarta. The digestibility measurement is carried out by providing a test diet which consists of 70% reference diet and 30% seaweed meal. Chromium oxide was used as an inert marker and added 0.6% to both reference and test diet. The average weight of experimental fish was 11.24±0.21 g and stocked 15 fish per aquarium, which is filled with 90L of water. The results showed that carbohydrate (NFE) is the largest component in seaweed. Ulva sp. had the highest digestibility in O. hasseltii (68.13%), while Palmaria sp., Sargassum sp., and Gracilaria sp. were 66.96%, 66.04%, and 65.23%, respectively. The four seaweeds used in this study were digestible by O. hasseltii and potential be used as an alternative ingredient in O. hasseltii diet.
