The study, published in the journal "Current Biology," found that whale-watching boats can cause whales to increase their heart rate, alter their breathing patterns, and change their swimming patterns. These changes indicate that the whales are feeling stressed, which could have negative effects on their health and survival.
The researchers studied two groups of humpback whales in the Pacific Ocean off the coast of British Columbia, Canada. One group was exposed to whale-watching boats, while the other group was not. The group exposed to the boats showed the signs of stress mentioned above, while the group not exposed to the boats did not.
The study's findings are concerning, as whale-watching is a popular tourist activity that is only becoming more popular. If whale-watching boats are causing whales stress, it could have a significant impact on the populations of these animals.
The researchers recommend that whale-watching operators take steps to minimize the stress they cause to whales. These steps include limiting the number of boats in an area, maintaining a safe distance from whales, and avoiding sudden changes in speed or direction.
Whale-watching can be a great way to learn about these amazing animals, but it's important to do so in a way that doesn't harm them. By following the recommendations of researchers, whale-watching operators can help protect these animals and ensure that they can continue to thrive in the wild.
