Giant gourami (Osphronemus goramy) is a freshwater aquaculture commodity of high economic value, yet its growth rate is relatively slow and the cost of fishmeal-based feed continues to rise. Microalgae such as Spirulina platensis and Chlorella vulgaris are known to contain high levels of protein, pigments, and bioactive compounds, making them a potential alternative nutrition supplement in giant gourami feed. This review was compiled using the literature review method, aiming to examine and summarize research findings on the effect of microalgae supplementation on the growth, body composition, and immune response of giant gourami. The results show that supplementation of Spirulina platensis and Chlorella vulgaris at a certain dose (around 6 g/kg feed) can improve growth, body composition, and the non-specific immune response of giant gourami. However, the optimal dose, microalgae processing method, and economic feasibility of its use at commercial aquaculture scale still require further research.
