Atlantic salmon, stocked and sought after
- Size
- Length: 70–90 cm, Weight: 3–7 kg
- Lifespan
- 3–5 years
- Diet
- Small fish, squid and crustaceans. In New Zealand, almost entirely farmed in deep, cold waters of the Marlborough Sounds and Stewart Island. Wild populations are rare, with escapees occasionally turning up in coastal waters.
- Habitat
- Farmed in deep, cold waters of the Marlborough Sounds and Stewart Island. Wild populations are rare. Most Atlantic salmon you eat never swam free in natural environments or rivers.
- Range
- New Zealand. Found in farms in the Marlborough Sounds and Stewart Island. Wild populations are rare, with occasional escapees from farms. Introduced from Northern Hemisphere for aquaculture purposes.
- Endemism
- Invasive
- Main Threats
- None. This introduced species is farmed, not wild. Escapees occasionally turn up in Marlborough Sounds but do not establish self-sustaining wild populations. Salmon farming industry carefully managed to minimise impacts.
- Population
- Introduced. Not considered a wild population in New Zealand, though escapees from farms occasionally turn up in the sounds. Our salmon industry is entirely aquaculture-based, and it is one of the best.
- Conservation Status
- Introduced
The supermarket king of the seafood counter. This is the fish that most Kiwis think of when they think of salmon. It is pink, oily, rich and absolutely everywhere. But here is the twist. Almost none of them have ever seen the open ocean. Born in hatcheries, raised in sea pens and harvested before they get the chance to swim up a river and spawn. A salmon that has never seen a river. The lifecycle is truncated. The journey is artificial. The origin is industrial.
Escape artists possess an expensive taste. When they do get out of the farms, Atlantic salmon are surprisingly good at surviving in the wild. They feed on small fish, krill and anything else they can catch. But they do not breed successfully in New Zealand rivers. The waters are too warm, too variable and too full of predators for their eggs to survive. So every Atlantic salmon eaten started its life in a tank. A fish that cannot go home. The attempt fails. The cycle breaks. The population remains captive.
The flesh is the selling point. It is rich, pink and high in omega oils. It is almost impossible to mess up in the kitchen. It can be grilled, baked, smoked, poached or eaten raw. The fish that forgives mistakes. The versatility is high. The margin for error is wide. The result is consistent. The flavour is reliable. The texture is soft.
To eat Atlantic salmon is to eat the farmed favourite. It is the fish that put New Zealand on the aquaculture map, even if it never really belonged here. The fish of the supermarket chiller. The one grabbed on the way home because dinner plans were forgotten and salmon is always a good idea. The convenience is paramount. The availability is total. The connection to nature is severed.
The fillet sits in the plastic tray, pink and perfect. It has never seen a river. It has never leapt a waterfall. It has never fought its way upstream to spawn and die. It just grew in a pen. It ate pellets. It got harvested. The existence is controlled. The end is predetermined. The life is short.
And it tastes fine. That is the strange thing. It tastes fine. The quality is acceptable. The experience is mundane. The expectation is met. No one told it otherwise.
