It has a bluish-green back and silvery sides, blending well with its marine environment.
Its fins are small, and it has a long, narrow tail resembling that of a cod.
Adult hoki typically grow up to 90–120 cm in length and weigh around 2–3 kg.

Habitat:

Hoki fish are found primarily in cold, deep waters ranging from 200 to 800 meters.
They inhabit the continental slopes and deep ocean trenches.
The species prefers areas with soft, muddy seabeds, which provide an ideal environment for feeding.

Distribution:

It is one of New Zealand’s most prominent commercial fish species.

Environmental Adaptations:

The fish is well-adapted to low light and high-pressure conditions in deep-sea habitats.
Its streamlined body and efficient fins allow it to swim effortlessly in these depths.

Life Cycle and Feeding Habits

Hoki fish have a fascinating life cycle. They are long-lived species, with some reaching up to 25 years. Juveniles hatch from eggs and initially live in shallow waters. As they mature, they move to deeper waters, often at depths of 200–800 meters. Reproduction occurs in spawning grounds, typically during winter. Females release eggs, which are fertilized by males. These eggs float freely in the water until hatching.

Hoki are carnivorous and rely on a diet rich in small marine organisms. They primarily feed on crustaceans, small fish, and squid. Juveniles consume plankton and tiny invertebrates. Feeding occurs mostly at night when prey is abundant near the surface. Their diet helps maintain their fast growth and energy for reproduction.
