 There is high demand on the worldwide market as decline in wild stocks due to over-fishing and poaching means that the global market for abalone is greatly under supplied.Most pāua farms on-grow pāua that is produced from wild broodstock, however some farms have developed their own hatcheries and selective breeding programs to produce faster growing species, the pāua are then grown to market size (depending on conditions this usually takes 2 – 3 years) in either long trays with inflow of seawater at one end and out flow at the other, or smaller tanks with tipper buckets that regularly dump seawater into the tanks to recreate wave motion that the pāua experience in the wild.There are a number of different feeds used throughout the pāua's life-cycle.
