Recirculating Aquaculture Systems (RAS) represent a pivotal milestone in the evolution of aquaculture, offering a controlled environment where water is continuously recycled and cleaned. Unlike conventional farming methods reliant on open water systems, RAS minimizes environmental impact, enhances biosecurity, and maximizes resource efficiency. This innovation will be instrumental in addressing the sustainability challenges facing the aquaculture industry, reflecting a concerted effort to advance practices towards a more sustainable future.
In response to the increasing demands of RAS, there is understandably emphasis on optimizing nutrient density, digestibility, and understanding fish metabolisms within feed formulations. Achieving high nutrient density and digestibility in RAS feeds is crucial for maximizing feed (and biofilter) efficiency and minimizing fecal waste to the water. However, ensuring technical quality remain a challenge due to the stringent nutritional and raw material requirements. For water quality aspects, the need for high technical quality of the feed remains universal for the success of RAS operations:
Employing advanced manufacturing processes and implementing rigorous quality control measures are pivotal in mitigating the risk of feeding with feed of poor technical quality. A notable advancement in this regard is the integration of novel twin screw technology with specially developed screw profiles, aimed at enhancing the cook, homogeneity, and consistency of feeds. This technological innovation ensures that feeds maintain both their nutritional integrity and physical properties, making a significant difference in the impact of RAS and aquaculture.
By prioritizing technical quality and utilizing cutting-edge technologies, producers can optimize feed performance and contribute to the long-term sustainability and success of RAS aquaculture ventures.
