Nelson-based Greenshell mussel company SPATnz is publicly releasing the startling results of its multi-year breeding programme developed in partnership with Sanford, the Ministry for Primary Industries (MPI) and the Cawthron Institute. The results show that selected hatchery mussels can grow up to twice as fast as those caught from the wild. The work is expected to be worth around $200 million a year to the wider New Zealand economy*.
