Bivalve and seaweed farming systems result in measurable increases in fish and invertebrate abundance and diversity, new research from The Nature Conservancy, University of New England, University of Melbourne, and the University of Adelaide finds.
In the first comprehensive global review of studies quantifying the habitat benefits of mussel, oyster, clam, and seaweed farms, scientists found that these food production systems had a positive impact on marine habitat value in comparison to sites without farms. However, different aquaculture species and farming methods provided different outcomes. Aquaculture of bivalves – two-shelled animals like mussels, oysters, and clams – seems to provide habitat more effectively than aquaculture of seaweeds, though there is less research available reflecting the impact and benefits of the highly diverse seaweed farming methods and species.
“Unfortunately, aquaculture can have a history of mismanagement. With better research and understanding, we are beginning to recognize the full scope of benefits from aquaculture such as shellfish and seaweed farming, which will advance/improve our planning and practices” says Tiffany Waters, TNC’s Global Aquaculture Manager…
