Our underwater monitoring surveys have shown that the farm 鈥� which essentially exists as a living floating reef structure 鈥� appears to be increasing the local abundance of marine species, including brown crab, lobster and European seabass. Inshore fishermen on the Dorset and Devon coast rely on these species for substantial parts of their income. The vertically hanging ropes that are home to millions of blue mussels also attract fish and many other plants and animals that settle on the mussels. Underneath the ropes, crabs and lobsters feed on the mussel clumps that fall to the seabed. Although we know that crabs, lobsters and predatory fish utilise the site for food and shelter, due to the habitat enhancement that the ropes, moorings and fallen mussel clumps provide, we know very little about the movements of these predators around the farm, or how long they remain resident, or if there is movement between the farms and the MPA. By offering a refuge function, the farm may complement the MPA in its role of replenishment of local fished populations and may induce spillover benefits into existing fishing grounds, but this all depends on the movements of individual animals.

To investigate animal movements in and around the mussel farm and between the mussel farm and the MPA, this project tagged and tracked multiple species, including sea bass, brown crab, lobsters and crayfish, for up to two years. The tags emit a unique coded ping which is recorded and monitored by static receivers placed underwater around the farm and the MPA boundary.

This unique project which works in collaboration with the fishing industry has received strong support from the seafood industry, marine conservation groups and government agencies with responsibility for effective marine planning and licensing. All sectors supporting the view that robust scientific evidence will improve our understanding marine ecosystems and is vital to underpin policies and strategic decisions for sustainable and responsible use of our oceans.
