Rethinking fish waste in RAS

Fish waste in recirculating aquaculture systems (RAS) is no longer just a disposal issue, according to Alumichem’s Trevor Gent — it’s a potential resource. In a new podcast, he highlights seven critical strategies for turning fish sludge into value, from early-stage effluent planning and modular treatment design to nutrient recovery and regulatory reform.

The key takeaway: fish manure contains valuable nutrients that can be reused as fertiliser or biogas feedstock, reducing environmental impact and opening new revenue streams. By rethinking waste management, RAS operators can meet stricter discharge regulations while building more sustainable and economically resilient systems. Smarter sludge handling is essential to the future of land-based aquaculture.
