                    AQUACULTURE IN NEW ZEALAND

    Aquaculture is the propagation and husbandry of aquatic plants and animals to
supplement the natural supply. These activities can occur in both natural waters
and in artificial aquatic impoundments. The aquaculture industry in New Zealand
specialises in high quality products and is a significant export earner for New
Zealand. The main aquaculture activity in New Zealand is the farming of bi-
valves, in natural waters below high tide mark. The major species farmed are the
green lipped or Greenshell mussel and the Pacific oyster. The main mussel farm-
ing areas in the South Island are located in the Marlborough Sounds and in the
Nelson Golden Bay area. Further south, the main locations are at Stewart Island.
In the North Island, mussel farming is concentrated in the Coromandel area with
smaller areas in the Haurki Gulf and at Houhora Bay in the far north.
    The farming method consists of floating longlines from which lines drop car-
rying mussels are suspended. Farms are located in sheltered to semi-sheltered
areas where there is sufficient depth of water at low tide to keep the drop lines off
the bottom.
    The main Pacific oyster farming areas are located in sheltered sites on the
north-east coast of the North Island, with main centers at Bay of Islands, Whanga-
roa Harbour, Mahurangi Harbour, and the Coromandel area. The farming method
consists of oysters supported on structures (racks) erected at the optimum growing
level on the lower intertidal shore.
    Tenures for mussel farming have been granted over 3 920 hectares. An annual
crop of some 67 000 greenweight tonnes is produced. After processing, this has
an FOB value of approximately $ 140 000 000. Tenures for oyster farming have
been granted over 2 200 hectare. This results in an annual crop with an FOB value
of approximately $ 45 000 000.
    Other species that are farmed are king salmon and the New Zealand abalone
(known as paua). Salmon farming occurs only in the South Island either in sea
cages or in freshwater raceways. Annual production of salmon farms has re-
mained static over recent years at around 5 000 tons greenweight. The FOB value
of salmon exported from New Zealand was $ 35 000 000 in 1999.
    Paua farming occurs throughout the country, but is predominantly in the South
Island and the lower half of the North Island. Most paua are grown in barrrels
suspended in the water column. There are small of fledging industries for the flat
oyster, freshwater crayfish, Malaysian prawns, spiny lobsters and various aquatic
