The species has a widespread distribution, ​found in both the Atlantic and Pacific Oceans. Within these ​regions, Black Jacks inhabit tropical and subtropical waters, migrating only short distances for spawning.


Black Jacks are marine fishes that prefer warmer oceanic waters. They can be found ⁣at ‌a variety of depths from shallow coastal waters to ⁢depths around 360m. The​ suitable temperature range for this species is between 20 – 28°C.

When and Where to See

Black Jacks are most commonly sighted during the summer seasons, especially during the day when they are more active in hunting.

Best Fishing Locations

Although Black Jacks ⁣are widespread, they are especially abundant in the waters around:

  • Bahamas
  • Florida⁣ Keys, USA
  • Caribbean Sea
  • Red ⁤Sea
  • Hawaii, USA
  • Gulf of Mexico
  • Brazil
  • Australia
  • Japan
  • Mozambique

When‍ fishing for⁣ Black⁣ Jack, look for warm, clear deep waters. They often congregate near reefs, cliffs⁢ and drop-offs.

How to Catch

Live bait, particularly small fish or ⁤squid, generally attracts Black Jacks. They respond well‌ to trolling,⁢ or for the more adventurous, spearfishing. The best time to catch this species is typically during sunrise⁢ or sunset.

Identification Guide

Black Jacks have a distinct dark body with a bluish-black color, with elongated dorsal and anal fins. These features distinguish them from other similar Jack species. The adults usually have a white stripe⁤ running from the gill cover to the base of⁤ the tail.


Black ⁢Jacks are edible with ⁤white, flaky meat. They can be grilled,⁢ baked or fried. Nutritional‍ values ​vary but are generally ⁢high in protein and omega-3 ‌fatty acids.

Additional Information

The‍ species mainly feeds on smaller fish and invertebrates. They have few natural predators due to their size, but are ⁢vulnerable to ‌larger sharks and humans.⁢ Black Jacks are not‍ historically significant but are valued in sportfishing for their fighting⁣ ability.
