Background information and definitions
Certain vessel modifications may reduce the severity of injuries to marine or freshwater mammals in the event of a collision. This could include installing propeller guards, such as cages, that provide a physical barrier between the propeller blades and an animal (Van Waerebeek et al. 2007).
