Who are we?
Sustainable Aquaculture Services (SAS) was founded by Dr Andrew Whiston, a marine biologist and pioneer with more than 30 years of experience in designing and operating energy-efficient Recirculating Aquaculture Systems (RAS).
He is supported by a dedicated team of engineers and biologists who share a core belief: aquaculture can be more profitable without depleting natural ecosystems.
With decades of hands-on expertise spanning hatcheries, RAS farms, broodstock programmes, and environmental engineering, the SAS team brings both depth and realism to every project. We know what works — and, perhaps more importantly, what doesn’t.
Our independence means we are not tied to specific suppliers or technologies. Instead, we provide practical, evidence-based advice that helps clients reduce risk, optimise efficiency, and create lasting value in aquaculture projects.
