Sustainable Fish Farming through Plant-derived Feed Additives

Abstract Aquaculture is a rapidly expanding field. To reach global protein demand it needs sustainable and efficient methods to enhance fish growth and immunity. The use of synthetic hormones and antibiotics have raised a concern about residue, resistance and environmental impact and also to find natural alternatives. This review explains the use of medicinal plants and phytochemicals as natural growth hormone enhancers and immunostimulants in aquaculture. This study of peer-reviewed sources explains the use of natural sources and their impact on bioactive mechanisms, efficacy and species-specific response for integrating herbal feed additives into aquaculture.
