Potential for the commercial culture of the tropical sea urchin Tripneustes gratilla in Australia

The decline in sea urchin fisheries production has seen increasing interest in the commercial culture of sea urchins, including the fast-growing tropical Tripneustes gratilla. However, the establishment of commercial sea urchin culture ventures is hampered by a lack of data on optimal culture conditions for sea urchins. The information presented in this report provides data to bridge this knowledge gap and represents an important step forward in the realisation of commercial sea urchin aquaculture.
