Investigation into dead shellfish at marine reserve
The discovery of a large number of dead shellfish, in the Long Bay-Okura Marine Reserve on Auckland’s North Shore, has
sparked a multi-agency investigation led by the Department of Conservation(DOC).
The dead shellfish, mostly cockles, were found on the shoreline at the entrance to the Okura River estuary at the
northern end of the marine reserve.
The Department of Conservation(DOC) manages the marine reserve and is working with the Ministry of Primary
Industries(MPI) and Auckland Council to try and establish what caused the shellfish to die.
MPI are testing dead shellfish from the estuary to determine if they have been infected by a disease.
Auckland Council monitors the condition of the marine environment across the region. The council is pulling together
data it has gathered for the area to help the investigation and is looking to gather extra seawater samples from the
Okura River Estuary.
“We don’t know why the shellfish have died so we’re working with MPI and Auckland Council to try and establish the cause
of death,” says DOC Auckland Mainland Operations Manager Kirsty Prior.
