Background
History
The Anglesey Sea Zoo was opened in 1983 by David and Alison Lea-Wilson, who later founded the next door Halen Môn sea salt business. As owners of a lobster wholesale business, they realized lobster tanks had become attractions in themselves. In 2007 the attraction was sold to research ecologists who have since gone on to develop research and conservation projects based at the aquarium, as well as several community conservation initiatives.
