Abstract: Green seaweed Ulva has a fast growth rate and spreads in along the coastal zone of Indonesian waters. This species has a great bioactive compound that made it possible as one of natural sources to be used as an alternative fish feed ingredient phenolics, saponins, flavonoids, alkaloids, steroids. This potentiality could answer the problem of tilapia farmers from suffering the high cost of feed. Besides the ingredients, the utilization of Ulva-based fish feed could help increase the immune system. This review is specifically discuss the effect of green seaweed Ulva as fish feed ingredient to improve the growth performance and the immune system of Tilapia. Based on the literature review of proximate analysis, different species of Ulva have an additional nutrient content. From 4 species found U. fasciata, U. clathrata, U. lactuca, and U. rigida, the highest crude protein content was U. rigida as 27.11 %. Moreover, adding 5-25% Ulva into the fish feed could increase the growth performance, but supplementation higher than 30% could decrease the bodyweight of Tilapia. For additional information, Ulva has secondary metabolites that boost fish's immune system and resistance to pathogenic infections. This review is highlighted the utilization of Ulva in tilapia feed ingredients to growth performance and immune system based on its nutrient compounds and hematological parameters.
