Scientists trying to replicate rare mussel that plays important role in Hauraki Gulf

Auckland scientists are trying to replicate an almost extinct type of mussel that once played an important role in the ecology of the Hauraki Gulf. Horse mussels used to line the sea floor in many parts of Aotearoa, but over the past two decades they've been decimated by destructive fishing methods. The research is moving from lab to ocean, in the hope of giving fish and shellfish more places to live, and help to restore struggling fisheries. Bella Craig reports.
