Here are some ways to slow down shipping vessels to mitigate noise impacts on fish:
Speed limits: Establish and enforce speed limits for vessels in sensitive marine areas, particularly those known to be important fish habitats or migration routes.
Incentives: Provide economic incentives or tax breaks to shipping companies that voluntarily reduce their speed in designated areas.
Vessel design: Encourage the design and use of more energy-efficient vessels that can maintain slower speeds without significant reductions in cargo capacity or fuel efficiency.
Propeller modification: Use quieter propellers and thrusters that generate less noise and vibrations.
Route planning: Modify shipping routes to avoid sensitive marine areas or critical fish habitats, especially during sensitive periods such as spawning or migration.
Education and awareness: Increase awareness among shipping companies and crews about the impacts of vessel noise on fish and the importance of slowing down in sensitive areas.
