Hatchery

 Algae is grown for food to feed the broodstock (mum's and dad's), larvae(15 days of egg life) and spat (baby oysters).  The hatchery likes to give them a nutrious diet of 6 different types of algae.  It is grown inside lay-flat algae bags at around 20 degrees.  The bags are filled up with seawater, nutrients and starter culture for each algae type.  Luckily for us oyster farmers we don't have to go to all this trouble.  Out on the oyster leases it just all happens naturally.  Here you see juvenile oysters (spat) starting their growing cycle in upwellers.
