Wild Seahorses and Aquarium Trade Welfare

Millions of seahorses are removed from the wild annually for aquarium trade and traditional medicine, with most captive-kept seahorses dying within months due to specialized needs that aquariums rarely meet.

Key Facts

An estimated 37 million seahorses are removed from the wild annually
Most captured seahorses are dead within weeks of entering the aquarium trade
Seahorses are dietary specialists eating only live prey — challenging to maintain in captivity
Project Seahorse estimates global populations have declined 30-50% since the 1990s
Captive-bred seahorses accept frozen food and survive better than wild-caught individuals

Welfare Considerations

Wild-caught seahorses in aquariums face a cascade of welfare failures: capture stress, transport dehydration, introduction to tank environments without appropriate live food, and the inability to perform natural behaviors including elaborate courtship and pair-bonding. The majority die within weeks. Owners who purchase wild-caught seahorses believing they are providing appropriate care are unintentionally causing suffering through a chain of welfare failures beginning at the point of capture.

What You Can Do

Only purchase captive-bred seahorses from reputable specialist breeders if keeping them
Research seahorse dietary requirements thoroughly before purchase — they need live or frozen mysis shrimp
Avoid impulse purchasing seahorses in general pet stores with inadequate husbandry
Support Project Seahorse conservation and advocacy work
Advocate for stronger regulation of wild-caught seahorse trade
