King Mackerel (Scomberomorus cavalla) Fish Description

Also known as Spanish Mackerel or Kingfish, this migratory species belongs to the mackerel family specifically found in the Gulf of Mexico and the Atlantic Ocean. 

What makes the King Mackerel striking are the small and vaguely visible, loosely attached scales on their entire body. Its dorsal fin is totally without color and usually folded back into a groove (same with the pelvic fins). Generally, King Mackerel are olive in color on the back parts, with a white underbelly, and rosy, iridescent sides. The smaller King Mackerel may have some brown to yellowish spots on the flanks, smaller than that of the Atlantic Mackerel. Interestingly, the teeth of King Mackerel are highly similar to that of the Bluefish

 

King Mackerel Diet and Size

As an opportunistic carnivore with a voracious appetite, King Mackerel have several choices on their food menu. Depending on the season, they may feast on Blue Runner, Northern Mackerel, Striped Anchovy, Weakfish, Cutlassfish, Jack, Menhaden, and squid.  

This fish is considered of medium size, typically weighing around 30 pounds; some King Mackerel caught weighed a little over 90 pounds. Females weigh more than males. For example, at 7 years old, a female King Mackerel can weigh 22 pounds, whereas the male is only half as heavy.
