Use ‘mussel socks’ to prevent birds from attacking shellfish Bird Conservation

A randomised, replicated controlled experiment in October 2002 in three bays on Prince Edward Island, Canada (Dionne et al. 2006), found that mussel socks with a ‘sleeve’ of a biodegradable cotton-polyester mesh lost fewer medium-sized (20 mm) mussels to greater scaup Aythya marila predation than un-sleeved socks. Losses were similar for small (14 mm) and large (26 mm) mussels, but more small mussels migrated through sleeved socks (thus more vulnerable to predation).
