What to know about Seaweed integration boosts efficiency and cuts waste in aquaculture, study finds

A study from the University of Miami's Rosenstiel School examines the use of native macroalgae species in integrated multi-trophic aquaculture (IMTA) to reduce waste from marine finfish farming. The research provides a framework for selecting seaweed species that can absorb nutrient-rich effluent, potentially improving the sustainability and economics of aquaculture in the Southeast U.S. and Caribbean.
