Common Names

Members of the genus Carangoides are commonly known as "jacks", "trevallies", or "horse mackerel" depending on the specific species and geographic location. Some species have more specific common names such as the "bluefin jack" (Carangoides ferdau) or the "yellowtail scad" (Carangoides equula).

Characteristics

Carangoides species share several defining characteristics. They are typically elongated, compressed fish with a distinct, forked tail. Their dorsal fin is divided into two parts, a spiny anterior portion and a soft posterior portion. The anal fin is similarly divided. Their mouths are large, with prominent teeth, reflecting their predatory nature. They range in size from small to medium-sized, with most species reaching lengths of 30 to 60 centimeters.

Environment

Carangoides species inhabit a variety of marine environments. They are primarily found in coastal waters, including reefs, estuaries, and sandy bottoms. They can be found in both inshore and offshore habitats, often forming large schools. Some species are known to migrate seasonally, following changes in temperature and prey availability.

Diet

Carangoides are carnivorous fish that primarily feed on smaller fish, crustaceans, and cephalopods. They are opportunistic predators, taking advantage of available food sources in their environment. Their strong swimming abilities and sharp teeth allow them to effectively pursue and capture prey.

Economic Importance

Several Carangoides species are important for fisheries around the world. They are often caught for food, both for local consumption and international trade. They are also popular targets for recreational anglers. However, some species are facing overfishing and habitat loss, highlighting the need for sustainable management practices.

Some of the most common and well-known species within the Carangoides genus include:

  • Carangoides ferdau (Bluefin jack)
  • Carangoides equula (Yellowtail scad)
