Abstract
Aquaculture serves a crucial role in meeting the global seafood demand. However, it grapples with issues associated with disease outbreaks, oxidative stress, and the imperative of fostering sustainable development. The supplementation of resveratrol in aquafeed has demonstrated the potential in addressing these issues. Resveratrol (RSV), a polyphenolic bioactive compound known for its antioxidant, anti-inflammatory, and neuroprotective properties, has garnered attention in recent research. Studies suggest resveratrol supplementation in feed, typically at the concentration of 0.5–1%, enhances growth performances, immune responses, resistance against disease, and stress tolerance in aquatic species. Despite its high metabolic rate and shorter half-life, the bioactive nature of resveratrol makes it a recommended phytochemical in aquafeed, highlighting its potential to improve overall aquaculture health and sustainability. This review is designed to give a comprehensive knowledge about the effects of resveratrol in fish, focusing on its antioxidant properties, influence on growth, impact on immune response, and benefits as a feed supplement.
