  • Mussel and Pacific oyster remain the main species produced in terms of value and tonnage with production increasing by 6% and 31% respectively during 2016;
  • During 2016, 4.6 million Pacific oyster shells were produced for on-growing showing that markets both home and abroad are well established;
  • There has been an increase in both queen scallop production (33,000 to 155,000 shells) and scallop production (30,000 to 35,000 shells) since 2015;
  • Native oyster production increased very slightly from 200,000 to 201,000 shells in 2016. The sector continues to target a strong niche market;
