Seahorse Welfare and Conservation in UK Waters

Two seahorse species — spiny and short-snouted — live in UK coastal waters. They face threats from bycatch, habitat loss, and the international dried seahorse trade. Their welfare and conservation deserve greater attention.

Key Facts

Spiny seahorses and short-snouted seahorses are the two UK native seahorse species, found in seagrass meadows and maerl beds
Seahorses are among the few animals where males carry and give birth to young — males gestate eggs in a brood pouch
UK seahorse populations have declined due to seagrass habitat loss, bycatch in bottom-trawled fisheries, and accidental collection by divers
Seahorses are traded internationally in vast numbers for traditional medicine and the curio trade — an estimated 37 million annually
UK seahorses are protected under Schedule 5 of the Wildlife and Countryside Act 1981
The Seahorse Trust conducts population monitoring and diving education to protect UK populations
Seagrass — the primary seahorse habitat — has declined by 90% in the UK over the last century
Captive seahorse breeding for the aquarium trade has reduced some pressure on wild populations but welfare in tanks is often poor

Welfare Considerations

Seahorse welfare involves both the individual suffering of bycaught animals and the population-level consequences of habitat loss. Seahorses caught in trawl gear suffer and die in the net — their small size and delicate structure make survival from trawling effectively impossible. The international dried seahorse trade drives targeted fishing in many countries and is a major conservation and welfare concern. In the UK, protecting and restoring seagrass meadows is the most impactful single action for seahorse welfare — providing habitat addresses food availability, breeding success, and reduces bycatch exposure simultaneously.
