A few weeks ago I visited the aquaculture centre at Mahanga Bay in Wellington. One of their projects is to research the best method and types of paua to use for farming. The paua are grown in tanks and are fed either seaweed or pellets. The buckets tip water over them every 30 seconds or so to simulate the wave action that they would get in the ocean. This allows them to get oxygen. The small yellow tags are attached to the paua so that they can be traced.
I was amazed at the beautiful blue colour the outside of the shells had.
