Wild Seahorse Welfare and Trade | Animal Welfare Hub

Seahorses are traded live and dried in vast numbers for the aquarium and traditional medicine trade, with significant welfare implications during capture, transport, and keeping.

Key Facts

An estimated 20-25 million seahorses are traded annually — primarily for traditional Chinese medicine and the aquarium trade.
Wild-caught seahorses have extremely high mortality during transport — often exceeding 50% within the first few weeks of captivity.
Seahorses are specialist feeders requiring live prey (mysid shrimps) that is difficult to provide in captivity.
Seahorse populations have declined by 30% or more over the past decade due to overexploitation and habitat loss.
CITES Appendix II listing (2004) requires trade to be non-detrimental to wild populations, but enforcement is inconsistent.

Welfare Considerations

Seahorse welfare in trade is a twin crisis: the acute suffering of individual animals through capture, transportation mortality, and starvation in captivity, and the population-level welfare impact of declining wild numbers. Seahorses suffer greatly in the aquarium trade — their specialist dietary needs mean that most wild-caught individuals slowly starve in home aquaria. Captive-bred seahorses trained on frozen mysid shrimps fare better but represent a small minority of traded animals. The welfare case for avoiding wild-caught seahorses is strong.

What You Can Do

Never purchase wild-caught seahorses for home aquaria — the mortality rate during trade and captivity is extremely high.
If interested in seahorse keeping, seek only captive-bred individuals from reputable specialist breeders.
Support organisations advocating for stronger CITES enforcement for seahorse trade.
Donate to seahorse habitat protection programmes focusing on seagrass restoration and coral reef conservation.
