Thank you for your interest in how to be a responsible and safe vessel operator in the presence of marine wildlife.

Our "See a Blow, Go Slow" campaign provides information about Marine Mammal Regulations in Canada, how to avoid collisions with marine mammals, and what to do if a collision or entanglement occurs. 

If you have witnessed an incident of concern, please contact the DFO Incident Reporting Line at 1-800-465-4336 /

Key Points to Avoid Collision

"Be Whale Wise" Guidelines

What to Do if You Find an Entangled Whale

Marine Mammal Laws & Regulations

Whales, dolphins, and porpoises can surface very unpredictably in front of your vessel. Baleen whales such as Humpback Whales can remain submerged for 15 to 20 minutes and often exhibit random travel patterns.
 
Whales may surface without warning and can be difficult to avoid, especially if you are traveling at speed. They can also suddenly become acrobatic and breach without warning. To increase safety for both boaters and marine wildlife, the following key points are provided: 

• Always be on the lookout for blows and other indicators of whale presence such as aggregations of birds (see below).
• Watch for vessels flying the Whale Warning Flag. This signals that whales are near (see below).
• Increase vigilance in areas of known whale density.
• When you suspect you are in the vicinity of whales, slow down. 
• Speed should not be more than 7 knots when 200 to 400 m from a whale (distance depends on species, behaviour and location). 
• If kayaking, raft up.
• Stay clear of the whales' path.

• Do not position beside "bait balls" of small schooling fish (as indicated by aggregations of birds).

• Signal commercial vessels to the presence of whales through the use of the Whale Report Alert System app. 
• If, despite this vigilance, a whale surfaces within the legal distance, shut off your engine until you are sure the whale are beyond the legal distance.  
• If you experience or witness a collision or other incident of concern such as entanglement or disturbance, report to the DFO Incident Reporting Line at 1-800-465-4336 (or if out of cell range, report to VHF 16). If possible, without further stressing the whale, get photos that show the injury and allow the whale to be identified (dorsal and / or tail photos).  

Areas of Known Humpback Whale Density

The coloured areas on these maps indicate locations of known whale density off northeastern Vancouver Island, with the dark blue areas highlighting regions where enhanced caution is especially required. Note that the locations of individual marine mammals cannot be predicted with certainty, and therefore the key points to avoid collision should always be followed.

Know Your Flags

Note that only vessels flying a triangular yellow pennant (like the one to the left) are licensed by Fisheries and Oceans Canada (DFO) to undertake research on marine mammals. This may involve approaching marine mammals within the 200m limit for research purposes. The lettering MML indicates "Marine Mammal License" and the number identifies the individual researcher.

Additional Guidelines - "Be Whale Wise" 

• STOP FISHING within 1,000 m of Orca year-round and in all Canadian Pacific waters (this is to aid Chinook salmon recovery and discourage depredation - that the whales learn to take fish from fishing gear). 
• BE CAUTIOUS and COURTEOUS: approach areas of known or suspected marine wildlife activity with extreme caution. 
  Look in all directions before planning your approach or departure.
• DO NOT APPROACH whales from the front or from behind.  Always approach and depart whales from the side, moving in a direction parallel to the direction of the whales.
• STAY on the OFFSHORE side of the whales when they are traveling close to shore.
• LIMIT your viewing time to a recommended maximum of 30 minutes.  This will minimize the cumulative impact of many vessels and give consideration to other viewers.

Regarding bow and stern-riding porpoises and dolphins:

• DO NOT drive through groups of porpoises or dolphins to encourage bow or stern-riding.
• Should dolphins or porpoises choose to ride the bow wave of your vessel, avoid sudden course changes. Hold course and speed or reduce speed gradually.

What to Do if You Find an Entangled Whale

With increasing numbers of Humpbacks on BC's coast, the risk of whale entanglement has become greater. Preliminary results from research conducted by MERS and DFO suggest that over 47% of Humpbacks in BC have been entangled (>1,000 Humpbacks). This data provides an indication of how serious the risk of entanglement is but does not reveal how many Humpbacks die after becoming entangled.

What to do if you find an entangled whale:

• With great urgency, report the entanglement with location to the DFO Incident Line / VHF 16. 1-800-465-4336.
• If at all possible, remain with the whale at a distance until trained help arrives or another boat takes over tracking, otherwise the chances of relocating the whale are greatly diminished
• Take whatever video/photos are possible but maintain a distance that doesn't stress the whale.
• Do NOT attempt to remove any fishing gear or rope from the whale as it risks human and whale safety (has led to human death). Professional training and equipment are needed to assess the entanglement and proceed safely with the greatest chance of success. Often, much of the fishing gear in which the whale is entangled is not visible at the surface. If well-intentioned members of the public remove the gear at the surface, it is made much more difficult to: 

1. recognize that the whale is entangled and;
2. disentangle the whale even if it is relocated.

Trailing gear at the surface provides the opportunity for trained responders to attach a tag to track the whale and/or to attach floatation to maintain contact with and slow down an entangled whale. Loss of this gear can significantly reduce rescuers' ability to save the whale.
