Zoos & Captivity

Zoo Welfare: Aquarium Fish Welfare Standards

Public aquariums house millions of fish whose welfare is increasingly subject to the same scrutiny as terrestrial animals in zoological collections.

Key Facts

Major public aquariums collectively house millions of fish across thousands of species
Fish welfare in aquariums includes water quality, appropriate social groupings, and species-specific space requirements
Advances in fish welfare science are driving updates to aquarium husbandry guidelines
Many marine aquarium fish are still collected from wild reef systems rather than captive bred

Welfare Considerations

Fish welfare in public aquariums has historically received less attention than mammal and bird welfare in zoos. The growing scientific recognition of fish sentience is driving welcome updates to aquarium welfare standards and husbandry practices.

What You Can Do

Support aquariums demonstrating commitment to fish welfare science and improved husbandry
Avoid aquariums housing fish in clearly inadequate conditions
Engage with welfare organisations developing fish welfare standards for public aquariums
