National Dolphin Day is observed every year on April 14. The day was created by the Earth Island Institute, an environmental non-profit organization based in Berkeley, California, and was first observed in 1990 as part of a broader campaign against the devastating impact of tuna fishing on dolphin populations.
In the eastern Pacific Ocean, yellowfin tuna and dolphins tend to swim together, which led to dolphins being killed in vast numbers as fishing vessels targeted the tuna below. The observance helped fuel the push for what became one of the most recognizable environmental labels in the world. The Dolphin Safe tuna program has since cut Eastern Tropical Pacific dolphin deaths by over 99%, with Earth Island Institute reporting that 95% of global tuna boats now follow these standards.
Why National Dolphin Day Matters
While conservation is at its core, the day’s purpose has broadened considerably over the decades. National Dolphin Day now serves as a platform for public education about the threats dolphins face and the vital role they play in ocean ecosystems. Those threats include:
- Bycatch, where dolphins are accidentally caught in nets intended for other species
- Pollution from plastic waste and chemical contaminants
- Climate change, which disrupts ocean temperatures and the food chains dolphins depend on
The day also highlights how ecologically significant dolphins are as apex predators that help balance the marine environment and give marine biologists a valuable window into the health of the ocean.
The observance has grown from a niche awareness campaign into a global effort. It saw a notable surge in 2015, when it generated over 6,000 online mentions in a single day, and events now take place in 46 countries. The day is also listed under the American Veterinary Medical Association’s Pet Health Awareness Events.
