The ocean perch is a saltwater fish found in northern Pacific ocean. It is from the Sebastidae family of fish and its scientific name is Sebastes alutus. It is also sometimes referred to as the Pacific ocean perch, or simply POP.

The range of the ocean perch is mostly limited to the coasts of Japan and the Bering Sea, to shores of Alaska down to northern California. The depth range of the fish can vary, and it has been found both on the surface of the ocean waters and as deep as 2,700 feet (822 meters). It is most often found at depths between 540 and 960 feet (165 and 293 meters). Whatever the depth, the perch prefers colder waters, usually around 42 degrees Fahrenheit (6 degrees Celsius). The fish is usually found in schools.

The ocean perch is pink, and has small spines across its back. Usually it grows to about 20 inches (50 cm) in length and weighs around 4.6 pounds (2.1 kg). The fish survives mostly on a diet of krill and copepods. Larger fish of the species have also been known to eat shrimp and other fish, such as flatfish, and smelt. Its main predators are sablefish and halibut. Cod, arrowtooth flounder and other large fish have also been known to feed on the perch as well.

The lifespan of the ocean perch is very long, close to 100 years. The fish reaches maturity after about five to nine years. After that point it will spawn every fall, with the eggs hatching in early spring. The females of the species can lay up to 300,000 eggs in a lifetime.

While not a popular fish for aquarium enthusiasts or game fishermen, the ocean perch is extensively fished by commercial fishermen. Commercial fishing of the ocean perch was so extensive for a time that populations declined to a dangerous level. However, since 2003 measures have been put into place to prevent overfishing. These have largely been successful and have resulted in healthy populations of the perch returning throughout much of its natural habitat.

Even with the controls in place, ocean perch remain a very profitable catch for commercial fishermen. In 2008 more than 75 million pounds (34 million kg) of the fish were caught, bringing in an estimated value of more than $15 million. The ocean perch is a valued fish not only for its taste, but also for its nutritional value. It is very low in saturated fat, and high in vitamin B12.

Frequently Asked Questions

What exactly is an ocean perch?

An ocean perch is a type of fish belonging to the family Sebastidae, commonly found in the North Atlantic Ocean. Despite its name, it's not a true perch but rather a rockfish. These fish are known for their bright red or orange coloring and are popular for their firm, white flesh which is well-regarded for its flavor and texture in culinary circles.

Where can you find ocean perch?

Ocean perch are typically found in the North Atlantic, from the coast of Norway to the waters around Greenland and Iceland, and as far south as New Jersey in the United States. They inhabit deep waters, often between 100 to 1,000 meters, preferring rocky bottoms and areas with strong currents that bring a steady supply of food.

What do ocean perch eat?

Ocean perch are opportunistic feeders, primarily consuming small fish, shrimp, and other crustaceans. Their diet varies with availability and often includes planktonic organisms. They use their large mouths and sharp teeth to capture prey, playing a role in maintaining the balance of their marine ecosystems.

How long do ocean perch live?

Ocean perch are known for their longevity. They can live for up to 50 years, although the average lifespan is around 30 years. This extended lifespan contributes to their late maturity, with some not reproducing until they are 5 to 7 years old, which has implications for their population dynamics and fishing practices.

Are ocean perch endangered?

As of my knowledge cutoff in 2023, ocean perch are not classified as endangered. However, their populations have been affected by overfishing in the past. Sustainable fishing practices and regulations have been implemented to help maintain healthy populations. It's important to check current conservation statuses from organizations like the International Union for Conservation of Nature (IUCN) for updates.

Can you eat ocean perch, and what does it taste like?

Yes, ocean perch is edible and is considered a delicacy in many parts of the world. Its flesh is lean, flaky, and mild in flavor, making it a versatile ingredient in a variety of dishes. Ocean perch can be baked, fried, grilled, or poached, and is often praised for its sweet, slightly nutty taste that pairs well with a range of seasonings and sauces.

I stopped eating ocean perch a several years ago when the perch population was declining. It's nice to hear that protections were put into place to help this fish repopulate.
