Fish eating birds can cause great damage to a fish farm The damage is only partially in the animals eaten by the birds For each fish successfully caught and eaten, many others are damaged (see picture) In the case of shellfish (e g mussels on ropes), species such as the Eider duck can strip the ropes, partly though consumption but mainly through knocking several animals off the ropes for each animal eaten Birds also present a threat through transmission of disease to the farm from other farms and watercourses in the area They can also play a role as an intermediary host in some diseases such as eye fluke Wherever possible, birds should be eliminated from entering the farm by use of netting or other scaring devices Netting is the only complete solution as birds will very quickly become used to most scaring devices and choose to ignore them
