Blue mussels are boreo-temperate invertebrates that live in intertidal areas attached to rocks and other hard substrates by strong (and somewhat elastic) thread-like structures called byssal threads, secreted by byssal glands located in the foot of the mussel. The shell is black, blue-black or brown, tear-drop shaped and has concentric lines marking the outside; the inner shell is white. The ‘beard’ is the byssal threads allowing the mussel to attach to substrate. current pulling in water and plankton.

Horse mussels grow much larger – up to 20cm in length – and usually live below the low watermark. This species occurs all around the British Isles but is more common in the north. Water clarity and eelgrass coverage were unchanged. Two methods for establishing mussel beds were tested. A total of 44 tons of blue mussels were produced and established in beds over an area of 121,000 m2. Production of blue mussels directly on hemp sacs hanging on long-lines was the most effective method.
