Oreo (OEO)

Our oreo catch is made up of four different oreo species: black, smooth, spiky and warty oreo. These species are managed together under the Quota Management System as one group, but stocks are assessed according to species and location. Science indicates oreo catches and catch limits are sustainable across all of New Zealand’s major deepwater oreo fishing grounds.
