Threats

Threats:

"Mesoplodonts have been taken occasionally by whalers but are not presently the main targets of any hunt. Entanglement in fishing gear, especially gillnets in deep water (e.g., for billfish and tuna), is probably the most significant threat. In addition, there is evidence that mesoplodonts are susceptible to acoustic trauma caused, for example, by military activities (Rowles et al. 2000; Anonymous 2001)." (Reeves et al. 2003, p. 54)

List of Threats:

4.1.1.2	Accidental mortality - Bycatch - Fisheries-related - Netting (ongoing)
4.1.1.3	Accidental mortality - Bycatch - Fisheries-related - Entanglement (ongoing)
6.3.10	Pollution (affecting habitat and/or species) - Water pollution - Noise pollution (ongoing)
