Warmer weather is leading to an increase in "vulnerable and fragile" seahorses being disturbed, conservationists have said.

Seahorses are legally protected in the UK and anyone intending to seek them out or photograph them must have a licence.

The Marine Management Organisation (MMO) said it was stepping up efforts to inform people of the law after an increase in reported incidents, both accidental and deliberate.

Educational activities are being focused around Poole Harbour and Studland Bay in Dorset and Torbay in Devon, where some of the most significant populations are found.

A MMO spokesperson said: "We have seen an increase in incidents where people have unintentionally encountered seahorses whilst in the water, or whilst crabbing.

"We've also seen people diving or snorkelling with the likely specific intention to film or photograph seahorses.

"This sort of intentional activity is likely to disturb seahorses, would potentially constitute an offence and would require a wildlife licence."

MMO head of marine wildlife conservation Jess Churchill-Bissett said: "We can understand the fascination people have with our native seahorse species, however, they are incredibly vulnerable and fragile marine animals that are easily disturbed by human activities.

"...intentionally disturbing seahorses without a wildlife licence could result in enforcement action.

"This applies to all divers, snorkellers, and TV and film production companies who should be aware of their legal obligations."

Neil Garrick-Maidment, founder of the Seahorse Trust, said it had been "such a brilliant summer and a lot more people are in the water, snorkelling and diving".

He said publicity around eco-moorings and a no-anchor zone to protect seahorses also "tempts people to go and look" for them.

He said: "Seahorses are a delicate, sensitive animal.

"If found in a crab net, act quickly, keep them out of the water for as little time as possible, take a brief photo, then gently return them to the water away from seagulls.

"If you spot one while snorkelling or diving, be calm and keep your distance, no flash photography."

Garrick-Maidment also urged people to report all sightings of seahorses to add to the National Seahorse Database.

He said: "Knowledge of these precious animals is key to their protection."
