Mussel power: how an offshore shellfish farm is boosting marine life (theconversation.com)

Over the past 50 years, global aquaculture including fish, mussel and seaweed farms has grown dramatically. Almost half of the world’s wild-caught fish is used to produce fishmeal and oils that feed farmed fish.

Mussel farming provides a more sustainable alternative protein source for human diets, because mussels filter feed on plankton and do not have to be fed wild-caught fish. Mussel farming also takes some pressure off the need for so much industrial agriculture and fish farming, and could therefore help reduce greenhouse gas emissions of food production – in line with the UK’s goal to reach net zero by 2050.

Most mussel farms are typically located in sheltered bays but as space to grow mussels inshore is limited, there isn’t always room to grow mussels at scale.
