Killer whale [SEP] Whale watching
Whale watching continues to increase in popularity, but may have some problematic impacts on killer whales. Exposure to exhaust gasses from large amounts of vessel traffic are causing concern for the overall health of the 75 remaining southern resident killer whales (SRKWs) left as of early 2019. This population is followed by approximately 20 vessels for 12 hours a day during the months May–September. Researchers discovered that these vessels are in the line of sight for these whales for 98–99.5% of daylight hours. With so many vessels, the air quality around these whales deteriorates and impacts their health. Air pollutants that bind with exhaust fumes are responsible for the activation of the cytochrome P450 1A gene family.
