Our Shellfish Seed (Spat) 

Spawnless (triploid) Crassostrea Gigas 

Our spawnless batches are consistently returning results of 100% triploidy.  The benefits to our customers of having stock that doesn’t spawn are huge.  Our quality spawnless lines are in high demand.

Thoroughbred (ASI)(diploid) Crassostrea Gigas

Our premium line, produced from broodstock selected from the Australian Seafood Industries (ASI) genetic breeding program, is now in it’s tenth year.  The production of uniformly shaped oysters with even growth is proving very beneficial to the industry.

Spat Sales


Our standard sale size stock is graded off a 5,000 screen.  This screen produces an oyster of 7-10mm, just perfect for 3mm Seapa tubes or seed trays. 


We welcome enquiries for supply of 8,000 screen (10-15mm) and 10,000 screen (15-20mm) spat.
