AQUACULTURE
Where are the major Aquaculture areas in New Zealand?
Northland, Coromandel, Tasman & Golden Bays, Marlborough, Banks Peninsula & Stewart Island. Follow this link to a Map outlining the major aquacultural areas in New Zealand.

How many people are employed in the Aquaculture industry?
In Marlborough there are approximately 1,000 people directly employed in aquaculture. In addition, many more are involved in the "downstream or flow on" effects of the industry.


 

MUSSEL FARMS
When did commercial farming of mussels begin?
Commercial farming and processing of mussels began in the late 1970's but did not really expand until the early 1980's.

How many mussel farms are there?
There are approximately 645 mussel farms in New Zealand. The average lease is between three and five hectares although farms may vary from one hectare to 20 or more. Farmers do not own their farms but are granted a coastal permit by Regional Councils to use the water space.

How is a mussel farm set up?
Each three hectare farm would typically have nine longlines of 110 metres each. Each longline would support 3,500 to 4,000 metres of crop line. Each long line is supported by 50 to 70 polypropylene floats, each of which can support one tonne.

Can I view a mussel farm?
Local tourist operators in both Havelock and Picton operate cruises to view the mussel farms.



TRAINING
What type of industry training is available?
The Queen Charlotte College offer Aquaculture courses at year 11, 12 & 13, and the Seafood Industry Training Organisation provides industry specific training. See the careers page to find out more.



MUSSELS
How are mussels grown?
The bulk of the industry's spat (baby mussels) are gathered on 90 mile beach at the tip of the North Island where, at irregular times throughout the year, considerable quantities of newly settled spat attached to seaweed are washed up on the beaches. This spat is collected and quickly transported by air or truck to growers in other parts of the country.



Local spat catching also occurs in Golden Bay and Marlborough in selected bays. The spat is seeded out on spat ropes using cotton stocking at approximately 1000 to 5000 spat per metre of rope. After three to six months, the nursery lines are lifted and the young spat are stripped from the ropes and reseeded on a final production rope at approximately 150 to 200 per metre. Mussels take between 15 and 18 months to grow to a harvestable shell size of 90 to 100mm.



What do mussels eat?
The diet of a mussel includes single cell algae and planktonic animals. Mussels are filter feeders and each mussel is capable of filtering about 300 litres of water per day. With approximately 900 million mussels grown commercially in Marlborough Sounds, this means a massive 270 million tonnes of water is moved by mussels every day!



What is the Latin name for Mussels?
The Latin name for the green lipped mussel grown in the Marlborough Sounds is Perna canaliculus.



What is the difference between a male and female mussel?
The different sexes of mussels can be identified by their colour. The flesh of a sexually mature male is creamy white, while a female is a reddish apricot.



How do we ensure the Mussels for sale in the shops are safe to eat?
New Zealand's aquaculture industry has built its reputation on seafood produced in a clean safe environment and leads the world in its Quality Management Programmes
