Around 100 people, including TV wildlife expert Iolo Williams, gathered on the Stena Europe yesterday, to celebrate the launch of Sea Trust's Dolphin Coast project.

The project will see weekly dolphin days being run on the ferry throughout the summer season, where Sea Trust volunteers will monitor cetacean sightings from the bridge of the ferry and also give talks on marine life to tourists and visitors.

Last year's Dolphinathon, a marathon four-day dolphin spotting exercise, will also run again this summer.

The Dolphin Coast concept aims to promote sustainable tourism in Cardigan Bay. It is a collaboration between conservation groups, Stena, the tourist industry and local artists, to market the Pembrokeshire coastline as rich in wildlife and an ideal spot for eco tourism.

Among the guests at yesterday's launch was BBC conservationist Iolo Williams. Iolo is particularly passionate about the Pembrokeshire coastline.

"I think the Pembrokeshire coast and the waters round here are unrivaled worldwide because of the variety you get," Iolo told the Telegraph.

"fascinating things from sea squirts and star fish to lobsters and crabs and dogfish all kinds of things. We've got half the world's population of Manx shearwaters in Wales, most of those on Skomer and Skokholm.

"We've got 33,000 pairs of gannets on Grassholm, 6000 pairs of puffins on Skomer. Pembrokeshire's got a fantastic variety and anyone who comes here in the summer months can't fail to be impressed by the fantastic wildlife."
