Content overview: “UQ Researchers Turn Organic Waste into High-Protein Fishmeal Alternative to Curb Overfishi”. University of Queensland scientists have developed a process that converts organic waste into biogas, which is then used to grow a high-protein feed for farmed fish. This innovation could reduce the aquaculture industry's heavy reliance on fishmeal, a product made from wild-caught fish like anchovie This innovation could reduce the aquaculture industry's heavy reliance on fishmeal, a product made from wild-caught fish like anchovies and sardines.
Overfishing to produce fishmeal threatens marine ecosystems and food chains, affecting species such as tuna, salmon, and seabirds. By using waste streams—including food scraps and agricultural residues—the new method offers a sustainable, circular economy solution. It addresses both waste management and the growing demand for aquaculture feed, which is projected to rise as global seafood consumption increases.
