This report provides an overview of the application of the carrying capacity concept to marine farm development in coastal embayments. Detailed numerical models have been developed in a number of countries to predict the biomass of bivalves that can be supported by particular coastal ecosystems (i.e. their "carrying capacity"). The report draws upon this literature and research done by NIWA on the New Zealand mussel industry to describe the application of carrying capacity models to the management of coastal inlets and estuaries subject to mussel culture. In particular, the objectives of the report are:
To outline the factors affecting the carrying capacity of coastal embayments for mussel farming and likely variations in carrying capacity,
To review the carrying capacity models developed by NIWA,
To review the ecosystem effects that may be encountered in an area as the number of mussel farms increases, and
To outline the current level of understanding of the carrying capacity of New Zealand coastal waters for aquaculture.
