Police are investigating reports of a bot and jet skis disturbing dolphins and a whale in the Firth of Clyde.
At around 1.25pm a boat was seen very close to a pod of dolphins which included a young calf just off Greenock.
And police say that last Sunday two jet skis were seen near a whale which appeared to cause the animal some distress.
Dolphins are regularly spotted near Kilcreggan, Gourock and Greenock, while a humpback whale was seen in Loch Long on Sunday, before heading out to open water past Hunters Quay.
The Loch Long sighting is not being investigated and there is no suggestion that the yacht crew behaved wrongly.
Wildlife officer PC Jordan Edwards, said: “Following these reports enquiries are being carried out and I would like to remind people that it is an offence under the Wildlife and Countryside Act 1981 to intentionally or recklessly disturb or harass these protected species.
“Dolphins, whales, seals and porpoises are a wonderful site off our coasts but they can easily be disturbed and should not be closely approached or chased.
“If you are out on the water and lucky enough to see them, the best approach is to keep your distance, slow down if you are in a boat or on jet skis and if the animals come close then do not make any sudden changes in your speed or direction of travel.
“If you witness a wildlife disturbance or have any concerns about this type of incident then please contact us.”
Anyone with information should contact Police Scotland on 101, quoting incident number 3714 of Thursday, 14 June, 2023.
Jet skis are a public noise and amenity nuisance and should be banned.
