A current challenge for sustainable aquaculture is how to increase the quantities of farmed fish while also reducing waste products that can lead to the accumulation of harmful fish sludge.
New research aims to understand how this fish waste can be treated for use in aquaponics systems, by removing excessive carbon, yet preserving the mineral nutrients required by plants to grow.
In this study in Frontiers in Plant Science, researchers from the Department of Marine Sciences at the University of Gothenburg, Sweden, demonstrate a novel and effective way to convert this fish sludge into plant fertilizer and therefore improving the nutrients available for plants in hydroponic plant cultivation.
