Conservation Evidence: Evidence Data

Collected Evidence: Collected Evidence: Use ‘mussel socks’ to prevent birds from attacking shellfishA randomised, replicated controlled experiment in Canada found that fewer medium-sized mussels were taken from mussel socks with a protective ‘sleeve’, compared to un-sleeved socks. There were no differences for small or large mussels.
