Problems and Prospects of Crustacean Cultivation in
Recirculating Aquaculture Systems
Abstract
Recirculating Aquaculture Systems (RAS) are gaining recognition as an environmentally friendly and efficient approach for the cultivation of crustaceans, with a particular focus on Macrobrachium rosenbergii. This species stands out for its remarkable nutritional profile, beneficial biochemical composition, and strong market potential. Due to its adaptability to controlled rearing conditions and rapid groüth performance,M.rosenbergii is considered a valuable candidate for intensive aquaculture operations. Nevertheless, certain technological and biological limitations continue to constrain large-scale RAS production. Major challenges include optimizing feed strategies to enhance conversion efficiency, maintaining genetic variability to ensure stock resilience, mitigating cannibalistic interactions that lead to yield losses, and improving biofiltration processes to stabilize water parameters. Current research highlights that formulating high-quality, species-specific diets and adopting modern system designs such as automated environmental monitoring, advanced recirculation mechanisms, and integrated biological filtration can significantly increase production outcomes. By overcoming these barriers, RAS-based M. rosenbergii aquaculture can evolve into a more profitable, sustainable, and ecologically responsible production model, supporting the long-term development of the global aquaculture industry.
