A study reveals the first large-scale offshore mussel farm in the UK, located in Lyme Bay off South Devon's coast, has led to the restoration of shellfish reefs after 150 years. The research, published in Science of the Total Environment, shows the seabed has transformed into reefs, benefiting commercial fish and crustacean species. The farm has also uncovered a historic map from 1871 indicating rich shell beds, suggesting a potential return to the area's former biodiversity. The farm has been instrumental in providing refuge and feeding opportunities for European lobsters and crabs, according to the study.
