Background information and definitions
Marine and freshwater mammals may be harassed or subjected to harmful deterrents at wild fisheries in attempts to reduce mammal predation on fish catches and damage to gear. This may include using firecrackers and rifle shots, flashlights, banging steel poles or oars together, and chasing mammals with boats (e.g. Shaughnessy et al. 1981, Sepulveda et al. 2018). Regulations may be introduced and enforced to prevent the use of such measures.
