ScotAqua Ltd, owned by acquaculturist Stephen Laing (54), uses a particular system of aquaculture, which takes the waste produced by farmed fish or other aquatic creatures to supply the nutrients for plants grown hydroponically – which in turn purifies the water being used.

Typical components used in the process include a rearing tank for raising and feeding the fish, a biofilter where the nitrification bacteria can grow and convert ammonia into nitrates suitable for plants and a hydroponics subsystem where plants are grown by absorbing excess nutrients from the water.
