World Aquatic Animal Day
April 3
About World Aquatic Animal Day
World Aquatic Animal Day is observed on 3 April each year, raising awareness about the importance of aquatic animals and the threats they face from human activity. Founded in 2020 by the Aquatic Animal Law Initiative at Lewis & Clark Law School in Portland, Oregon, this day advocates for the legal protection and welfare of all animals that live in water.
What is World Aquatic Animal Day?
World Aquatic Animal Day is an annual observance dedicated to raising awareness about the billions of animals that inhabit the world’s oceans, rivers, lakes, and wetlands. The term “aquatic animals” encompasses far more than fish; it includes marine mammals such as whales and dolphins, crustaceans, molluscs, sea turtles, corals, aquatic birds, amphibians, and even aquatic insects. The day was established by the Aquatic Animal Law Initiative (AALI) and the Animal Law Clinic at the Center for Animal Law Studies at Lewis & Clark Law School, co-founded by Amy P. Wilson and Kathy Hessler. Each year, the day features a specific theme and hosts events including panel discussions, educational webinars, and community actions.
When is World Aquatic Animal Day?
World Aquatic Animal Day is observed on 3 April every year. In 2026, it falls on a Friday. The date is fixed and does not change from year to year.
Why World Aquatic Animal Day Matters
Aquatic ecosystems are under enormous pressure. Overfishing has pushed many fish populations to the brink, with the Food and Agriculture Organization estimating that approximately 35% of global fish stocks are now overfished. Plastic pollution poses a severe threat, with an estimated 8 million tonnes of plastic entering the oceans every year, harming marine mammals, sea birds, turtles, and fish. Coral reefs, which support approximately 25% of all marine species, have declined by roughly 50% since 1950 due to warming oceans, acidification, and pollution.
Beyond environmental concerns, there are significant animal welfare issues. Trillions of fish are caught or farmed each year, often with little consideration for their welfare. Scientific research increasingly demonstrates that fish and other aquatic animals are capable of experiencing pain and distress, yet legal protections for these creatures remain far weaker than for terrestrial animals. World Aquatic Animal Day brings these overlooked issues into public conversation and advocates for stronger legal frameworks to protect aquatic life.

How to Get Involved in World Aquatic Animal Day
There are meaningful actions you can take to support aquatic animals:
- Attend an official event – The Aquatic Animal Law Initiative hosts webinars, panel discussions, and educational events each year on 3 April. Check their website for the 2026 programme and register to participate.
- Reduce your plastic consumption – Single-use plastics are one of the biggest threats to aquatic life. Switch to reusable bags, bottles, and containers. Even small changes, multiplied across millions of people, make a tangible difference.
- Make sustainable seafood choices – If you eat seafood, choose sustainably sourced options. Look for certifications from the Marine Stewardship Council (MSC) or Aquaculture Stewardship Council (ASC), which indicate responsible fishing and farming practices.
- Support marine conservation organisations – Donate to or volunteer with organisations working to protect aquatic habitats, such as the Marine Conservation Society, Oceana, or the Coral Reef Alliance.
- Participate in a beach or river cleanup – Join a local cleanup event to remove litter from waterways and coastlines. Even inland cleanups matter, as rubbish in rivers eventually reaches the sea.
- Educate yourself and others – Watch a documentary about marine life or read about aquatic animal welfare. Share what you learn with friends and family. Awareness is the foundation of change.
- Advocate for stronger legal protections – Write to your elected representatives urging stronger laws to protect aquatic ecosystems and animal welfare. The AALI provides resources and templates to help with advocacy efforts.
History of World Aquatic Animal Day
World Aquatic Animal Day was launched on 3 April 2020 as a project of the Aquatic Animal Law Initiative (AALI) at the Center for Animal Law Studies at Lewis & Clark Law School in Portland, Oregon. The idea was conceived by Amy P. Wilson and co-founded with Kathy Hessler, both legal scholars who recognised a significant gap in legal protections for aquatic animals compared to their terrestrial counterparts.
The founders were motivated by the growing body of scientific evidence demonstrating that fish and other aquatic animals are sentient beings capable of experiencing pain, fear, and stress. Despite this evidence, aquatic animals remained largely excluded from animal welfare legislation in most countries. The AALI established the day to bring public attention to this disparity and to advocate for legal reform.
Since its first observance, World Aquatic Animal Day has grown each year, attracting participation from academic institutions, conservation organisations, and animal welfare groups across the globe. Each annual observance features a specific theme; past themes have included “Animals as Community” and explorations of the interconnectedness between aquatic species and human societies.
Noteworthy Facts About Aquatic Animals
- Approximately 71% of the Earth’s surface is covered by water, and aquatic ecosystems are home to an estimated 2.2 million species, with many yet to be discovered.
- Coral reefs support roughly 25% of all known marine species despite covering less than 1% of the ocean floor.
- An estimated 1 to 2.7 trillion fish are caught from the wild each year, making them by far the most exploited vertebrate group on the planet.
- Scientific studies have shown that fish can recognise individual faces, use tools, and have long-term memories, challenging the outdated notion that they are simple creatures.
- The blue whale, the largest aquatic animal, can reach lengths of 30 metres and weigh up to 200 tonnes, making it the largest animal ever known to have existed.
