NZ King Salmon, in association with Te Atiawa, was first issued a marine farm licence for a Clay Point salmon farm in 1994.
The licence was not immediately brought to production because the company decided to focus on adding value to its product attracting market pull, rather than pushing volume growth which inevitably targets commodity markets and the risk of price pressure inherent in such markets..
More recently consumer demand for salmon has been on the increase reflecting a global trend away from processed foods towards nutrition and healthy eating. New Zealand sales by value increased by 20 per cent alone in 2007 so three years ago NZ King Salmon began discussions with Te Atiawa as to how new salmon production could be effected at the Clay Point licence.
Clay Point is on the northern tip of the Marlborough Sounds, north east of French Pass. It is accessible only by sea.
It is a unique environment for growing salmon with the cool Southland current that runs up the east coat of the South Island and in to the Tory Channel keeping water temperatures cooler.
Cooler water equates to better growth rates for salmon and healthier fish. The current also washes away surplus food and waste that would otherwise settle under the farm. The water flow is 27 cm per second, nearly twice that at NZ King Salmon’s nearby Te Pangu farm.
The Clay Point property contains the 1.16 ha farm and accommodation barge. The barge provides accommodation for up to five staff 24/7, storage provision for eight days feed, energy generation, office areas, feed disbursement, net cleaning technology, feed monitoring systems, storage for water and fuel, sanitary management, stability system tanks, diving equipment and diver transition facilities.
Other innovations at the site
a state of the art mooring system that uses tension logging to monitor the mooring lines sending information to operators about any unusual strains that may be occurring;
an automated net cleaner that works underwater doing away with the need to laboriously lift nets from the water for cleaning;
new feeding technology capable of dispersing 180 kg of palletised fish food every minute;
surface and underwater video cameras enabling operators to monitor feeding from a single position.
The new farm is the company’s fifth but that does not mean production will increase 20 per cent. NZ King Salmon’s strategy includes reducing stocking densities across all its farms while also increasing production.
The farm’s success is dependent on good clean water so the smaller the environmental footprint the better. NZ King Salmon uses no chemicals, vaccines or antibiotics in its production and the company’s promotional material stresses the pristine natural environment of the Marlborough Sounds.
