TV boosts Wales' shellfish industry revival

Plans have gone ahead for an oyster bed in Swansea not used since the 1920s to be repopulated, and products on offer from Wales have become more diverse.

Llandudno's Christopher Owen - who was the Welsh culinary association's chef of the year for 2012 - believes TV cookery programmes have brought shellfish back into culinary fashion.

"Ten years ago it was pretty impossible to source locally-grown seafood other than cockles and mussels - not that it mattered, because no-one wanted to order it in any case," he told BBC News.

But Prof Mike Kaiser from Bangor University's School of Ocean Sciences warned that the picture was not all positive.

Whilst the majority of the Welsh coast is rated A, too many sewers were still being allowed to overflow into the sea.

"There is an issue in bad weather when sewers flood which means that in the Menai Strait in particular the water quality can dip to the B standard," he told the news source.
