RAS Systems

Term from Aquaculture industry explained for recruiters

RAS (Recirculating Aquaculture Systems) are modern fish farming facilities that reuse water to grow fish in controlled indoor environments. Think of it like a high-tech fish tank system that allows farmers to raise fish anywhere, not just near oceans or lakes. These systems clean and recycle water continuously, control temperature, and monitor water quality, making fish farming more environmentally friendly and efficient. It's similar to hydroponic systems used in plant farming, but for fish. When you see this term in resumes, it usually indicates experience with modern, sustainable fish farming methods.
