This document summarizes the experimental facilities at Cefas, including over 220 glass and GRP freshwater and saltwater tanks that can be customized for studies. The facility has temperature control, programmable lighting, and alarm systems. It houses a variety of fish and invertebrate species and can design custom systems. The facility treats all effluent water onsite before releasing it.
