What is Halibut?

Halibut is a large flatfish found in the colder coastal waters of the Northern Hemisphere. They belong to the Pleuronectidae family of right-eye flounders.

Halibut have a distinct body shape with both eyes on one side, usually the right side. Their upper side is dark brown to olive green, while the lower side is white, helping them blend in with the seabed. They can reach impressive sizes, over 8 feet long and weighing more than 700 pounds.

This species is prized for its delicious, mild-flavored white flesh and is popular in the culinary world. They are opportunistic predators, feeding on fish, squid, crustaceans, and other marine organisms.

Halibut fisheries exist in various countries, with both commercial and recreational fishing. Some species are managed and regulated to ensure sustainability due to their popularity and the impact of fishing on their populations.

What is Cod?

Cod is a group of fish in the Gadidae family commonly found in the North Atlantic and Arctic Ocean. The most well-known species is the Atlantic cod, native to the North Atlantic. They are medium to large-sized fish, reaching lengths of 2 to 3 feet and weighing up to 50 pounds.

Cod have a slender body with greenish-brown coloring on the back and sides. Their white, flaky flesh is mild in flavor and highly prized in cooking.

They are bottom-dwelling carnivores, feeding on smaller fish, crustaceans, and mollusks. Historically, cod fishing has been significant for both commercial and subsistence purposes, but overfishing and habitat degradation have caused population declines. Measures are now in place to regulate and manage cod fisheries for sustainability and recovery.

What is the Difference Between Halibut and Cod?

For a quick rundown of the differences between halibut and cod, refer to this table.

Differences	Halibut	Cod
Physical Characteristics	Flat shape with eyes on one side	Streamline shape with a broad square tail fin
Flavor	Mild and delicate	Strong and meaty
Texture	Firm and meaty	Soft and flaky
Nutrition	High in omega-3 fatty acids and protein	Low in fat and calories

Physical Characteristics

Halibut and cod have some distinct physical differences. Here are some of the key characteristics that set them apart:

• Body Shape: Halibut have a flat, diamond-shaped body, whereas cod have a more elongated and cylindrical body.
• Eye Placement: Halibut are "right-eyed" flatfish, which means both of their eyes are located on the same side (typically the right side) of their body. In contrast, cod have eyes on opposite sides of their head, like most other fish.
• Size: Halibut are generally larger than cod. While cod typically reach lengths of 2 to 3 feet (60 to 90 centimeters), halibut can grow much larger, with some species reaching lengths of over 8 feet (2.4 meters).
• Coloration: Halibut have a distinctive coloration, with the upper side (eyed side) being dark brown to olive green, and the lower side (blind side) being white. In comparison, cod have a more uniform coloration, with greenish-brown on their back and sides, fading to a lighter color on the belly.
• Dorsal Fin: Halibut have a continuous dorsal fin that extends along their entire back, while cod have two separate dorsal fins—a shorter one closer to the head and a longer one toward the tail.
• Habitat: Halibut are primarily found in colder coastal waters of the North Atlantic and North Pacific oceans, while cod have a wider distribution, inhabiting the North Atlantic and Arctic Ocean.

These physical differences reflect the unique adaptations of each species to their respective habitats and lifestyles.
