Background information and definitions
This intervention involves creating artificial habitats for marine and freshwater mammals. For example, artificial reefs are structures intentionally built on the seafloor using natural or man-made materials, such as rocks or concrete blocks. These structures may attract a variety of marine life and form reef ecosystems, providing a foraging resource for predatory marine mammals. However, some man-made materials used for artificial reefs, such as scrap tyres, may have toxic effects (Collins et al. 2002). High concentrations of fish at artificial reefs may also attract fishing activities and increase the risk of mammal entanglement in fishing gear.
