What is amberjack?
Amberjack, a name that evokes excitement and awe among anglers worldwide, are an impressive group of marine fish known for their powerful, hard-fighting nature and delectable taste. These large, pelagic game fish are members of the family Carangidae, which includes jacks, pompanos, and trevallies. In this article, we explore the biology, ecology, and distribution of amberjack, as well as discuss their significance in the world of recreational and commercial fishing.
Taxonomy and Distribution
The genus Seriola, which includes several species of amberjack, is widely distributed throughout temperate and tropical seas. The most notable species are:
- Greater amberjack (Seriola dumerili) – Found in both the Atlantic and Indo-Pacific regions.
- Yellowtail amberjack (Seriola lalandi) – Found in the southern hemisphere, primarily in the waters around Australia, New Zealand, and South Africa.
- Lesser amberjack (Seriola fasciata) – Primarily inhabits the western Atlantic Ocean.
Morphology and Coloration
Amberjack are characterized by their elongated, streamlined bodies, which are well-adapted for fast swimming and powerful bursts of speed. They possess a single dorsal fin, with the anterior section consisting of strong, spiny rays, and the posterior section composed of soft rays. Amberjack can grow quite large, with greater amberjack reaching lengths of up to 2 meters and weights of over 70 kilograms.
Amberjack exhibits a range of colours, varying from bluish-green or olive along their dorsal surfaces to silver or white ventrally. Many species also display a distinct diagonal band or dark stripe running from their eyes to their dorsal fins, which may fade as the fish matures.
Ecology and Habitat
Amberjack are pelagic, predominantly found in offshore waters, often near or around underwater structures such as reefs, wrecks, and oil platforms. They are also known to form schools, particularly during their juvenile stages. The schooling behaviour helps the fish find food and provides protection from predators.
Diet and Feeding Behavior
Amberjack are agile predators and will utilize their speed to capture a range of prey, including fish, squid, and crustaceans. Not only does this opportunistic lifestyle provide them with sustenance but it also ensures that populations of smaller creatures in the marine food chain remain balanced. As such, amberjacks play an essential role in keeping oceanic ecosystems thriving.
Reproduction and Life Cycle
As the spring and summer months arrive, Amberjack begin to reproduce with their seasonal spawning behaviour. The eggs and sperm are released into the water column where fertilization occurs externally, leading to planktonic larvae that drift until they find a suitably hospitable habitat in which they develop into juvenile fish. Amberjack grow quickly; some species reach sexual maturity within just a few years based on environmental conditions.
Fishing and Commercial Significance
Amberjack are highly sought after by both recreational and commercial fishermen due to their powerful fight and delicious taste. Sport fishers often target amberjack using live bait, artificial lures, or jigs, with techniques such as trolling, jigging, or drifting. Commercially, amberjack are harvested using longlines and purse seine nets, and their meat is sold fresh, frozen, or smoked.
How to catch amberjack?
If you want to experience the ultimate thrill of angling, then catching amberjack is the perfect way. Amberjacks are renowned for their strength and tenacity, creating a thrilling challenge that will test even skilled fishermen. To increase your odds of success when fishing for these powerful game fish, here are some useful tips and techniques to bear in mind:
Location
Amberjack are often found in offshore waters near underwater structures such as reefs, wrecks, and oil platforms. These structures provide shelter and attract baitfish, which in turn attract amberjack.
Tackle
Use a medium to heavy-duty rod and reel setup that can handle the strength and size of amberjack. A strong 6-7 foot rod paired with a conventional reel loaded with 50-80 lb braided or monofilament line is recommended. Additionally, use a strong, corrosion-resistant hook (such as circle or live bait hooks) and a 60-100 lb fluorocarbon leader to increase your chances of landing these powerful fish.
Bait
Amberjack are opportunistic predators and will readily take a variety of live and artificial baits. Live bait, such as pinfish, blue runners, or small bonito, tends to be the most effective. For artificial bait, use large, brightly colored jigs, vertical jigs, or deep-diving plugs that mimic the appearance and movement of their natural prey.
Technique
Live Bait: When using live bait, you can either drift or anchor near a structure where amberjack are likely to be present. Drop your bait down to the desired depth, usually close to the bottom or near the structure. Allow the bait to swim naturally and wait for the amberjack to strike.
Artificial Bait: For vertical jigging, drop the jig to the bottom of the depth where the fish are holding, and then rapidly retrieve it with an up-and-down motion. This imitates the movement of a wounded or fleeing baitfish, which can trigger a strike from an amberjack.
Setting the Hook and Fighting the Fish
Amberjack are known for its strong, fast runs and powerful resistance. Once you feel a strike, set the hook firmly by swiftly lifting the rod tip. Keep the line tight and maintain constant pressure on the fish. Amberjack will often try to dive back into the structure, so be prepared to apply extra pressure to prevent them from breaking the line or getting tangled.
Landing the Fish
When the amberjack is close to the boat, use a gaff or large landing net to secure the fish. Be cautious, as these powerful fish can still thrash and cause injury even when they are tired.
Regulations
Always familiarize yourself with the local fishing regulations, including size and catch limits, closed seasons, and any specific gear requirements. This helps to ensure sustainable fishing practices and the long-term health of amberjack populations.
With the right location, tackle, and technique, you can enjoy the thrill of catching amberjack and savour the reward of their delicious meat.
Conservation Status
While some regional amberjack populations have experienced declines due to overfishing, habitat degradation, and bycatch, many species are not currently considered to be at significant risk. However, it is essential to maintain sustainable fishing practices and implement effective management measures to ensure the long-term survival and health of these important game fish. This includes implementing size and catch limits, seasonal closures, and protecting critical habitats.
Aquaculture and Stock Enhancement
As the global demand for amberjack meat continues to increase, aquaculture offers an innovative and effective approach to meeting this need while reducing strain on wild populations. Japan, South Korea, and Spain are among a growing number of countries that have made considerable progress with their own farming methods of producing high-quality fish for consumption. Furthermore, numerous stock enhancement programs involving the release of hatchery-reared juvenile amberjacks into natural habitats have been implemented in various areas around the world; aiming to revive depleted numbers as well as sustain genetic diversity within these species.
Is amberjack good to eat?
Amberjack’s firm, flavorful meat lends itself well to a variety of culinary preparations. It can be enjoyed raw in sashimi or sushi dishes, grilled, broiled, or baked. In Japan, the fish is known as “Kanpachi” or “Buri,” and is highly prized for its rich taste and versatility in traditional Japanese cuisine.
Health Benefits
Amberjack is a powerhouse of nutrition, with substantial amounts of the highest-quality proteins, healthy fats and valuable vitamins and minerals. It contains generous levels of omega-3 fatty acids renowned for their contribution to optimal cardiovascular health, decreased inflammation and enhanced brain function.
