2. The impact of seeding density on spat losses on New Zealand's Greenshell™ mussel (Perna canaliculus) farms.

High losses of seed mussels (spat) during the early stages of mussel aquaculture is a major problem that results in the inefficient use of spat, which severely disrupts production and ultimately constrains industry growth. These losses are thought to be caused by a variety of factors including...
