Water quality, waste production, and off‐flavor characterization in a depuration system stocked with market‐size Atlantic salmon Salmo salar
Abstract Land‐based Atlantic salmon, Salmo salar, grow‐out facilities utilize depuration to remediate off‐flavor. Water used in this process is either discharged or repurposed as supply water in recirculating aquaculture systems (RAS). Both approaches require an understanding of water quality and wa...
