Cero mackerel, also known as Scomberomorus regalis, is a species of fish that belongs to the Scombridae family. It is commonly found in the western Atlantic Ocean, particularly in the Gulf of Mexico and the Caribbean Sea.

More importantly, this ray-finned bony fish is known for its distinctive appearance, with its sleek and slender body and blue-green coloration that fades into silver along the belly. At the same time, it is prized for its fast and aggressive nature. Its meat is also highly valued for its rich flavor and firm texture, making it a popular ingredient in various culinary dishes.

In recent years, numerous viable efforts have been made to promote sustainable fishing practices and raise awareness about the importance of preserving cero mackerel populations.

This article will examine the cero mackerel by exploring its appearance, habitat, diet, reproduction, and threats. We will also list interesting facts about this popular game fish species and answer some pressing frequently asked questions.


The cero mackerel’s body is elongated and slightly compressed, with a pointed head and a forked tail. The upper body is blue-green, while the lower body is often silvery-white. This fish species has a series of dark stripes running vertically along its sides, which become more prominent when the fish is excited.

Moreover, the dorsal fin of the cero mackerel is dark in color, while the other fins are lighter. They have a pointed snout with a large mouth filled with sharp teeth.

So, this fish species is similar in color and appearance to the Atlantic Spanish mackerel. It’s the longitudinal stripe that sets it apart.

The average length of cero mackerel is around 30-40 inches, although they can grow up to 48 inches and weigh up to 25 pounds. Overall, the cero mackerel is a beautiful and impressive fish species.


Cero mackerel is found in the western Atlantic Ocean, from North Carolina to Brazil. They are typically found in coastal waters, where they prefer to swim in schools ranging from 20 to 100 feet.

If that’s not enough, cero mackerel is also commonly found around coral reefs and rocky structures, and they are known to be active both during the day and at night.


Cero mackerel is a predatory fish that has a row of small teeth in its mouth. It uses these features to feed on smaller fish, including sardines, herring, and anchovies. Moreover, studies show that they feed on squid and shrimp.

Notably, cero mackerel hunt in schools, using their speed and agility to catch their prey quickly. They are also known to follow schools of baitfish, attacking them from below and causing them to scatter.


Cero mackerel spawn in the spring and summer, with peak spawning in May and June. During this time, males and females will form large spawning aggregations in shallow water near reefs or other underwater structures.

Females release plenty of eggs into the water, where the males then fertilize them. After spawning, cero mackerel will typically disperse and return to deeper water.


The cero mackerel population is stable. The International Union for Conservation of Nature ranks it as the Least Concern. However, like all marine species, cero mackerel are vulnerable to overfishing and a range of other threats.

The major threats to this species include:

  • Overfishing: Cero mackerel is a popular commercial and recreational fish species, so they often need to catch up. This can lead to a decline in their population and make it difficult for them to reproduce and maintain their numbers.
  • Habitat loss: Cero mackerel require specific marine habitats, including coral reefs and seagrass beds, to survive. These habitats are threatened by coastal development, pollution, and other human activities.
  • Climate change: The warming of the oceans and changes in ocean currents and water temperatures can impact the distribution and migration patterns of cero mackerel, affecting their ability to find suitable habitats and food sources.
  • Predation: Cero mackerel are preyed upon by larger fish species, such as tuna and sharks. Overfishing of these predator species can increase the number of cero mackerel, which can put pressure on their prey species.
  • Pollution: Pollutants such as oil spills, plastic debris, and chemical runoff can impact the health of Cero mackerel and their habitats, leading to declines in their populations.

Overall, it is important to manage the fishing of cero mackerel sustainably and to protect their habitats to ensure their continued survival.
