Introduction

Aquaculture is expanding rapidly, with land-based farming gaining traction across the globe. The rising demand for high-quality seafood has triggered a paradigm shift, driving the industry toward unprecedented intensification. At the center of this transformation is the emergence of Recirculating Aquaculture Systems (RAS) and closed-containment technologies that mark a significant leap in production potential. RAS offers year-round output, freedom from coastal constraints and greater control over the rearing environment, making it a cornerstone of modern aquaculture.

As producers seek to maximize yield, the risk of systemic failure grows exponentially, jeopardizing health of the biomass and overall wellbeing.Yet a critical factor often overlooked is water quality, the invisible force that shapes biological and financial outcomes. In high-density systems, water quality, biosecurity and system resilience become not just operational concerns but existential ones. Managing an optimal balance between productivity and vulnerability is now one of aquaculture’s most urgent challenges.We encourage you to take a closer look at both the water-related challenges facing aquaculture and the best practices available to effectively resolve them.
