Aqua farming in South Africa is gaining momentum. Large sea snails better known as Abalone, is a seafood delicacy that's extremely popular in Asian countries like China and Japan.

The ban has since been lifted but now farmers are looking at new ways to feed the demand for this unique marine species. Sumitra Nydoo has this story.
