A new four-part series looks at one of the natural wonders of our country. Y Fenai follows the people living and working on the shores of the Menai Strait over four seasons.
The first programme looks at the Menai in the autumn. As the days shorten, there is plenty of activity on the river.
Dr Greta Hughes works as a Fisheries Officer on the Menai. One of her duties is to make sure the cockles thrive and controlling how many are collected.
"If too many cockles are gathered, there aren't enough there for the wildlife living in the Strait," explains Greta. "And if there are too many left behind, there's not enough room for the young ones to settle and the entire stock dies."
The autumn is also when mussels are harvested and Skipper John Jones shows how he picks them on one of Britain's largest mussel farms.
Although some areas of the fishing industry are thriving, others are disappearing slowly. Over the past quarter of a century the sea has provided a livelihood for local man Gareth Owen, but lately, things have been difficult for him.
"Over the past three years things have deteriorated," says Gareth. "It's enough to break your heart."
We'll also meet Caernarfon Harbour Master Richard Jones who follows six generations of his family on the Menai Strait, and naturalist Siôn Roberts will talk about the area's wildlife. The programme will also follow Tomos Tudor, a young lad who hopes to begin a distinguished career in sailing, like his well-known uncle Richard Tudor, as he practises on the Menai's tricky current.
