The first broodstock spawning, which resulted in eggs are being incubated today 16 July.
This is the first of a number of Kingfish production runs between Clean Seas Tuna's two hatcheries at Arno Bay and Port Augusta.
With the onset of this spawning Clean Seas Tuna is on target to produce Kingfish juveniles ready for distribution between the grow out sites at Fitzgerald Bay, Arno Bay and Port Lincoln.
Clean Seas Tuna Limited has also announced the commission of one of the largest most sophisticated specialised harvesting vessels in the Southern Hemisphere - The Ulysses II.
The 32 metre vessel is purpose fitted out to preserve its sustainable seafood cargo under constant cold chain control from ocean to plate.
Clean Seas Tuna says it is the most advanced in its design and is capable of harvesting up to A$1 million worth of Kingfish in one operation if necessary.
The vessel has capacity for up to 100 tonnes of zero degrees water on board.
Chairman Hagen Stehr stated: "If the vessel was to be built at present it would cost close to A$4 million."
The management added: "The vessel is a valuable addition and crucial in creating a top brand for its fish around the world."
