Do’s and Don’ts in Whale(鲸) Watching
The Department of Fisheries and Oceans has developed guidelines for whale watching in Johnstone Strait, where killer whales are found on a daily basis each summer．It is strongly remended 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 meters, 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 meters from your vessel．
Leave the area slowly, gradually moving faster when you are more than 300 meters 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 ing 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 meters 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 municating with other vessels, and make sure that all operators are aware of the whale watching guidelines．
