Grey and common seals face legal and illegal killing due to fishery conflicts despite protected status.
Seals shot for fishery protection may not be killed cleanly suffering from non-fatal wounds. Animals shot in water may dive and die slowly from injuries without being recovered. Pups orphaned by shooting of nursing mothers may starve. The effectiveness of lethal control is questionable as shooting individual seals does not deter others. Non-lethal deterrents including acoustic devices and physical barriers are available alternatives but require investment.
