Sentinel Shellfish Contaminant Monitoring programme (Auckland Region)

Physical, biological and chemical monitoring of shellfish within the Auckland region for Auckland Council. The objective is to identify contaminants with abnormally high concentrations in shellfish, detect changes in contaminant levels over time, detect differences in contaminant levels between locations, and evaluate the effectiveness of measures aimed at reducing contaminant loads.

Sampling sites are located in Tamaki Estuary, Waitemata Harbour and Manukau Harbour.

Sampling frequency = annual (oysters: Nov/Dec, mussels: Sep to Dec).

Sampling began in 1987 for oystera and 1999 for mussels (not at all sites) and is ongoing.

Number of sites = 11 total: 4 wild-caught sites (oysters) and 7 'deployment' sites (mussels). Extent of site = varies.

Number of replicates = 5 oyster or 5 mussel samples per site, pre-deployment samples are also taken for mussel sites.

Measured variables = Shellfish analysed for metals (regular suite of 6 metals analysed), organics (including PAHs, PCBs and OCP's), condition index.

Sampling protocol & QA = Internal monitoring protocol, has two sections: wild-caught oyster samples, and farmed mussels (sourced from the Coromandel, assembled on rigs in Kelly Tarlton's Underwater World, deployed on site and then retrieved 3 months later by the ARC dive team by boat. QA = Internal, a bulk reference sample is analyzed by the organics lab.
