8. Vessel Strikes

Strikes from vessels, whether they are commercial or recreational, can injure or kill whales. Collisions with vessels are a threat to St. Lawrence Estuary Belugas and North Atlantic Right Whales and have recently emerged as a threat for Southern Resident Killer Whales.

The mechanisms by which whales can detect and prevent being struck by a vessel are not completely understood. For North Atlantic Right Whales, risk analyses focused on vessel speed suggest that the probability of lethal injury from vessel collisions decreases when vessel speed is reduced, e.g., reducing vessel speed to less than 13 knots increases the likelihood that a whale struck by a vessel will avoid serious injury or death. Footnote 35, Footnote 36

8.1 Summary of Key Themes

Indigenous groups, governments and other stakeholders provided feedback on the threat of vessel strikes for the North Atlantic Right Whale.

8.2 What Indigenous Groups Said

In general, Indigenous participants supported the approach of removing vessel traffic from areas where North Atlantic Right Whales are present and/or restricting vessel speed in those areas.

Indigenous participants felt that:

Suggestions from Indigenous participants were:

8.3 What Governments and Other Stakeholders Said

North Atlantic Right Whale

Remove vessel traffic from North Atlantic Right Whale critical habitat and high use areas.

Some participants felt it would be relatively easy to reduce or eliminate commercial shipping vessels in North Atlantic Right Whale critical habitat by relocating shipping lanes (e.g., Grand Manan basin) and encouraging greater compliance with guidelines (e.g., Roseway basin). Removal of commercial shipping vessels away from North Atlantic Right Whale critical habitat in Grand Manan Basin and Roseway Basin is mostly accomplished. However, reducing the numbers of other vessels could be more difficult (e.g., whale watching for Grand Manan Basin, fishing, fisheries enforcement, military, and pleasure vessels for both critical habitat areas).

Participants requested that more specific information be provided about the potential effectiveness of the priority management actions and the expected operational, marine safety and economic impacts on the shipping industry.

Participant suggestions included:

Some participants said that the Government of Canada needs new management tools to allow faster, more responsive action to the changing movements of North Atlantic Right Whales. To be effective, government needs the ability to react quickly. Participants made a similar suggestion with respect to the threat of entanglement.

Implement vessel speed restrictions in areas where North Atlantic Right Whales are present.

As with actions aimed at removing or reducing vessel traffic, participants requested more specific information about the implementation of vessel speed restrictions in areas where North Atlantic Right Whales are present.

Participant suggestions included:

Increase awareness and monitoring of vessel traffic restrictions in North Atlantic Right Whale critical habitat.

Participants held different views about whether voluntary measures would be sufficient to remove vessel traffic or if new regulations would be needed:

8.4 What the General Public Said

The Let's Talk Whales online portal included an open-ended question designed to capture general thoughts on some of the actions identified by scientists in the Phase 1 science assessment to address the threat of vessel strikes. The actions included for this particular threat were:
