                                             Do's and Don'ts in Whale (鲸) Watching

     The Department of Fisheries and Oceans has developed guidelines for whale watching in Johnston Strait,

where killer whales are found on a daily basis each summer. It is strongly recommended that vessel (船只)

operators follow these guidelines for all kinds of whales.

● Approach whales from the side, not from the front or the back.

● Approach no closer than 100 metres, then stop the boat but keep the engine on.

● Keep noise levels down-no horns, whistles or racing of engines.

● Start your boat only after the whales are more than 100 metres from your vessel.

● Leave the area slowly, gradually moving faster when you are more than 300 metres from the whales.

● Approach and leave slowly, avoiding sudden changes in speed or direction.

● Avoid disturbing groups of resting whales.

● Keep at low speeds and remain in the same direction if travelling side by side with whales.

● When whales are travelling close to shore, avoid crowding them near the shore or coming between the

whales and the shore.

● Limit the time spent with any group of whales to less than 30 minutes at a time when within 100 to 200

metres of whales.

● If there is more than one vessel at the same observation spot, be sure to avoid any boat position that would

result in surrounding the whales.

● Work together by communicating with other vessels, and make sure that all operators are aware of the

whale watching guidelines.
