large, slow, prized beyond its numbers

Size
Length: 50–80 cm, Weight: 3–8 kg
Lifespan
20–30 years
Diet
Feeds on small crustaceans, worms and small fish. Forages over rocky reefs and sandy bottoms. Uses small mouth to pluck prey from rocks and kelp. Feeds most actively at dawn and dusk.
Habitat
Rocky reefs and sandy bottoms from 10 to 150 metres depth. Prefers areas with strong currents and clear water. Often near drop-offs, underwater pinnacles and current-swept channels.
Range
Temperate waters around New Zealand from Northland to Campbell Plateau. Most common off east coast of South Island and around Chatham Islands. Also found in southern Australia and Tasmania.
Endemism
Native
Main Threats
Recreational overfishing is primary threat. Bycatch in commercial gill nets and trawls. Localised depletion near populated areas. Climate change affects kelp habitat quality. Highly prized by recreational fishers.
Population
Populations declined in easily accessed areas near cities and towns. Species still abundant in remote southern locations. Size and bag limits help manage recreational take. Quota management sets commercial catch limits.
Conservation Status
Not Threatened
It sounds like a trumpet. That is the name. And it is loud. The trumpeter is named for the loud, trumpeting sound it makes when taken from the water. The sound is produced by the swim bladder vibrating against the spine. It is amplified by the body cavity. A fish with a built-in horn. A fish that announces its own capture. The noise is involuntary. The attention is unwanted. But it happens. Every time. Its body is covered in distinctive horizontal stripes. These give it its alternative name, striped trumpeter. The stripes are dark brown to black. They run the length of the body like racing stripes. A fish that looks fast, even when it is sitting still. A fish that wants to be known as serious. The pattern is diagnostic. The appearance is striking. It stands out against the reef. Or the sand. Depending on the angle. It is one of the most highly prized recreational fish in New Zealand. Valued for its spectacular fighting ability. And its firm, white, delicately flavoured flesh. A trumpeter on the line is a trumpeter in the air. It tail-walks across the surface. It sounds its horn. It does not give up easily. That is why people chase it. The struggle is part of the appeal. The reward is culinary. And experiential. The memory lasts. The meal satisfies. The Māori name Kohikohi means to collect or gather. It possibly refers to the way it gathers in schools around rocky reefs. The people who came before knew this fish. They gathered when the trumpeters gathered. That was the rhythm. The fish came. The people followed. The synchrony was observed. The name reflects the behaviour. The connection is behavioural. Not just nutritional. The gathering is central. To the fish. And to the fishers. It can live for three decades in the wild. Slow-growing and late to mature. This makes it vulnerable to overfishing. A trumpeter takes years to reach breeding size. Remove too many and the population takes decades to recover. That is the problem with slow fish. They cannot keep up. The biology dictates the pace. The pressure ignores it. The result is decline. In some areas. Not all. But enough to notice. Populations have declined in heavily fished areas. Size limits and bag limits apply. Marine reserves provide refuge in some areas. But the big ones are getting harder to find. The scarcity is visible. The management is active. The outcome is uncertain. The species persists. But the abundance has shifted. From the accessible to the remote. From the shallow to the deep. The distribution changes. The pressure remains. That is the trumpeter. Striped, noisy and delicious. A fish that sounds like a horn. Fights like a champion. And asks for careful management. The request is implicit. The need is explicit. The fish carries on. In the currents. On the reefs. In the nets. And on the lines. It endures. For now.
