Long- and short-term solutions for mitigating hazardous noise exposure and noise levels on board vessels from the small-scale fishing fleet of Newfoundland and Labrador
Fish harvesting in Newfoundland and Labrador (NL) is prominently a small-scale industry. This is an important activity in the rural NL, providing a mean of livelihood and identity to many coastal communities. Fishing is also one of the most dangerous professions both in the province and worldwide, w...

Fish harvesting in Newfoundland and Labrador (NL) is prominently a small-scale industry. This is an important activity in the rural NL, providing a mean of livelihood and identity to many coastal communities. Fishing is also one of the most dangerous professions both in the province and worldwide, with high incidence of reported casualties, accidents, and injuries. Among many health and safety issues of the fish harvesting profession, elevated noise levels pose a subtle threat. Prolonged exposure to noise is known to induce noise-induced hearing loss (NIHL), and high noise levels are known to reduce the habitability of fishing vessels, increase fatigue, and ultimately add to the risk of accidents and injuries. This PhD research aims to assess noise-related hazards on the small-scale NL fishing fleet (less than 24m length overall) and to provide short-term (minimal vessel and gear modification, use of protection devices), and long-term (integration of an acoustic design for noise control on fishing vessels) solutions to mitigate on-board high noise levels and exposures.
