Orange roughy

Orange roughy (Hoplostethus atlanticus), also known as deep sea perch, is a deep-sea fish of the slimehead family (Trachichthyidae). It is a commercial fish species found in the cold, deep waters of the Atlantic and Indo-Pacific oceans.

Description

The orange roughy is notable for its extraordinary lifespan, which can reach up to 150 years. It is a large, slow-growing species, reaching up to 75 cm in length and 7 kg in weight. The fish is named for its bright orange skin, while its flesh is firm and white.

Distribution and habitat

Orange roughy are found in the Atlantic and Indo-Pacific oceans, typically at depths of 180 to 1,800 meters. They prefer steep continental slopes, seamounts, and underwater plateaus.

Diet

The diet of the orange roughy is largely made up of zooplankton, small fish, and squid.

Commercial fishing

Orange roughy has been commercially fished since the late 1970s. Due to its slow growth and late maturity, the species is vulnerable to overfishing. In recent years, measures have been taken to manage and conserve orange roughy stocks.

Conservation status

The IUCN currently lists the orange roughy as Near Threatened. Overfishing has led to a significant reduction in its population in some areas.

Culinary use

In culinary contexts, orange roughy is valued for its mild flavor and low fat content. It is often baked, broiled, or fried.
