Kingfish Vs Wahoo (What Is The Difference)?




The main difference between kingfish and wahoo is that kingfish, also known as king mackerel, are part of the mackerel family, while wahoo are part of the scombrid family, which includes fish like tuna and mackerel.

These two fish species often get confused due to their similar physical appearance and habitat. However, there are some noticeable differences between them when it comes to size, behavior, and taste.

As a marine biologist, I have had the opportunity to study and interact with both of these fascinating fish species up close. In this blog post, I will be diving deep into the differences between kingfish and wahoo, from their size and appearance to their distribution, feeding habits, and more.

Size and Appearance


Kingfish, or king mackerel (Scomberomorus cavalla), have a long and slender body. They are typically bluish-green on their back, fading to silvery-white on their belly. The most distinguishing feature of kingfish is the presence of a lateral line that starts high on the shoulder and curves down to the tail, allowing them to detect movement and vibrations in the water. Adult kingfish can grow up to 72 inches in length and can weigh up to 100 pounds.


Wahoo (Acanthocybium solandri) also have a long, slender body but are more streamlined compared to kingfish. They have a dark blue back and a silver underside. One of the most striking features of wahoo is their vertical blue bars, which are more pronounced than those of kingfish. Wahoo are known for their speed and agility, reaching speeds of up to 60 miles per hour. Adult wahoo can grow up to 98 inches in length and can weigh up to 180 pounds.

Distribution and Habitat


Kingfish are found in tropical and subtropical waters of the western Atlantic Ocean, from Massachusetts to Brazil, including the Gulf of Mexico and the Caribbean Sea. They prefer water temperatures between 68°F and 86°F and are usually found near the surface in depths of up to 300 feet. Kingfish are migratory and move inshore during the warmer months to spawn and feed.


Wahoo have a more extensive distribution compared to kingfish, being found in tropical and subtropical waters worldwide. They can be found in the Atlantic, Indian, and Pacific Oceans, as well as the Mediterranean and Caribbean Seas. Wahoo prefer water temperatures above 72°F and are usually found near the surface in depths of up to 600 feet. They are highly migratory and can cover vast distances in search of food.

Feeding Habits


Kingfish are voracious predators and feed primarily on schooling fish such as menhaden, herring, and anchovies. They also prey on squid and crustaceans. Kingfish are known for their unique hunting technique, where they swim through schools of fish with their mouths open, slashing their prey with their sharp teeth.


Wahoo have a diverse diet, feeding on a variety of fish species, including mackerel, flying fish, and even smaller tuna. They are also known to consume squid and other cephalopods. Wahoo are ambush predators, using their speed and agility to surprise and capture their prey.

Fishing Techniques


Kingfish are popular targets for both recreational and commercial fishermen. They are often caught using trolling techniques with live or artificial bait. Kingfish are also known to be attracted to structures such as reefs and shipwrecks, making them a popular target for bottom fishing.


Wahoo are highly sought after by sport fishermen due to their speed, power, and impressive aerial displays when hooked. They are typically caught using high-speed trolling techniques with artificial lures or rigged baitfish. Wahoo are also known to be attracted to floating debris and can often be found around fish aggregating devices (FADs).

Taste and Culinary Uses


Kingfish have a rich, distinct flavor and a firm, oily texture. They are often enjoyed grilled, smoked, or in sushi and sashimi preparations. Due to their high oil content, kingfish can be prone to spoilage, so it is essential to handle them properly and consume them fresh.


Wahoo have a mild, delicate flavor and a firm, white flesh that is less oily than kingfish. They are highly versatile in the kitchen and can be prepared in various ways, including grilling, broiling, and frying. Wahoo is also popular in sushi and sashimi dishes.

Conservation Status


Kingfish populations are considered stable, with no significant threats to their population. However, they are susceptible to overfishing due to their migratory nature and the popularity of kingfish among recreational and commercial fishermen. Management measures such as size limits, bag limits, and closed seasons have been implemented in some regions to help maintain sustainable kingfish populations.


Wahoo populations are also considered stable, and there are no significant threats to their population. They are managed primarily through size limits and bag limits, and there are no commercial quotas or closed seasons for wahoo. However, as with any fish species, responsible fishing practices are essential to ensuring the long-term sustainability of wahoo populations.


In conclusion, while kingfish and wahoo may appear similar at first glance, they are distinct species with noticeable differences in size, appearance, habitat, and behavior. Both species are popular among fishermen and seafood lovers alike, and their populations are currently stable. As a marine biologist, I am always fascinated by the unique characteristics of these two fish species and the important role they play in our marine ecosystems. Here are ten facts about kingfish and wahoo to remember:

1. Kingfish are part of the mackerel family, while wahoo belong to the scombrid family.
2. Kingfish can grow up to 72 inches and weigh up to 100 pounds, while wahoo can grow up to 98 inches and weigh up to 180 pounds.
3. Kingfish have a more restricted distribution, while wahoo are found worldwide in tropical and subtropical waters.
4. Both species are migratory and can cover vast distances in search of food and spawning grounds.
5. Kingfish primarily feed on schooling fish, while wahoo have a more diverse diet.
6. Both kingfish and wahoo are popular targets for recreational and commercial fishermen.
7. Kingfish have a rich, distinct flavor, while wahoo have a mild, delicate flavor.
8. Both species are currently considered stable in terms of their conservation status.
9. Management measures such as size limits, bag limits, and closed seasons are implemented in some regions for kingfish.
10. Responsible fishing practices are essential for maintaining sustainable populations of both kingfish and wahoo.


Does kingfish have mercury?

Yes, kingfish can contain mercury. Like many types of fish, kingfish may accumulate mercury in their tissues as a result of environmental pollution. It is recommended to limit consumption of kingfish and other high-mercury fish, especially for pregnant women and young children.

What fish is king fish similar to?

King fish, also known as king mackerel, is similar to other mackerel species, such as Spanish mackerel and cero mackerel.

Is kingfish like tuna?

No, kingfish and tuna are not the same. They are different species of fish with distinct characteristics and flavor profiles. Kingfish is known for its firm texture and rich flavor, while tuna has a softer texture and a milder taste.

Are kingfish tasty?

Yes, kingfish is considered a tasty fish with a firm texture and rich flavor. It can be prepared in a variety of ways, including grilling, baking, or frying.

Can you eat kingfish?

Yes, kingfish is a popular fish to eat and is considered safe for consumption. However, it is important to ensure that the fish is properly cleaned and cooked to avoid any potential health risks.

What kind of fish is kingfish?

Kingfish is a common name for several different species of fish, including the yellowtail kingfish, Spanish mackerel, and king mackerel.
