Background information and definitions
Marine and freshwater mammals may be harassed or subjected to harmful deterrents at aquaculture systems in attempts to reduce mammal predation on fish stocks and damage to gear. This may include using bait that is distasteful or emetic (induces vomiting), explosives and warning shots, electric fencing or chasing mammals with boats. Regulations may be introduced and enforced to prevent the use of such measures at aquaculture systems. This may also include the inappropriate use of acoustic devices, which may cause hearing damage and disturbance to both target and non-target mammals (Götz & Janik 2013).
