Duo from Rathlin Island target Japan's open seaweed market

A small island off the north coast of Ireland has emerged as an unlikely potential supplier of edible seaweed to Japan – a country whose own stocks have been hit by the Fukushima nuclear disaster.

A mother and son team from Rathlin, an isolated island with a population of around 100, are trying to exploit the gap in the market caused by the contamination of the waters around the ruptured reactor.
