New Zealand’s Greenshell™ mussel (Perna canaliculus ) industry stands as the cornerstone of the nation’s aquaculture sector, boasting an annual production exceeding 100,000 tonnes and contributing over $350 million NZD to the economy. However, the growth and long-term sustainability of this industry is threatened by the highly inefficient use of wild spat that is crucial for seeding its farms. Despite harvesting over 350 billion spat from the wild each year to supply the industry, only 1.5 billion of these are retained on farms from seeding through to harvest, representing losses of over 99%. This presentation will summarize the findings from several studies which were undertaken to begin to develop alternative approaches to nursery culture of Greenshell™ mussels to reduce spat losses and improve production efficiency. This presentation will demonstrate that although further research is required, common approaches to the nursery culture of bivalves used elsewhere and in other species, might also represent a promising approach for the nursery culture of Greenshell™ mussels. This presentation will also outline the next steps required for transforming the Greenshell™ production cycle in New Zealand.
