Blackfin Tuna (Thunnus atlanticus) Fish Description

Also known as Deep-Bodied Tunny, Albacore, or Bonite Nore in French, the Blackfin Tuna is the smallest tuna in the Thunnus genus. This fish has an oval-shaped body colored black with some faded yellow near the finlets and on the sides. 

Sometimes, the Blackfin Tuna’s sides can be bluish-black, whereas its belly is white. It possesses a vast, brown stripe along the portion of its eye. It has an eye-catching lateral band colored yellow or gold which fades upon its death. Its silvery abdomen has some vertical rows embedded with pale dots. 

Another feature that adds to the Blackfin Tuna’s beauty are the bronze reflections on its dusky dorsal finlets.

Diet and Size

In general, Blackfin Tuna reaches up to 39 inches in length and up to 46 lb in weight. On the other hand, it falls prey to Skipjack Tuna, Blue Marlin, and Dolphinfish.

Blackfin Tuna love mesopelagic and epipelagic meals alike. They feast on squid and fish primarily, but they also like the larvae of decapods, stomatopods, amphipods, and crustaceans especially crabs and shrimps.

Blackfin Tuna — Fishing Techniques

The Blackfin Tuna is listed as one of the most important species for both commercial and recreational fisheries. Anglers love to catch them because they are noted for being fierce fighters. Moreover, their flesh is superbly tasty; they are usually marketed fresh then processed and canned.

Some of the most common methods used to catch them are drift fishing, and trolling. You can also try capturing them using live bait and poles. According to the most seasoned anglers, what works best in hauling Blackfin Tuna are vertical jigging and chunking. Make sure to scale down your leader and hooks; this is because Blackfin Tuna have sharp eyesight.

Apart from using #30 fluorocarbons for leaders, you should also have a 5/0 to 6/0 size circle hook. Note that you can lure Blackfin Tuna into your boat by using some live chum particularly pilchards.

Blackfin Tuna Habitat and Distribution

Most of the Blackfin Tuna population is concentrated in the Gulf of Mexico to Rio de Janeiro, the Caribbean Sea, and Martha’s Vineyard in Massachusetts.  They prefer swimming in warm waters over 68 °F. 

Blackfin Tuna usually occur in oceanic waters near the coastline. They usually inhabit the areas near the continental shelves. They are at their peak during autumn, winter, and spring in Florida Keys.

Bluefin Tuna

Bluefin Tuna (Thunnus Thhynnus) Description 

The Atlantic Bluefin Tuna is one of the largest, fastest, and most fantastically colored fishes. They are shiny blue on the top, shimmery silver/white on the bottom, and reddish rear fins. They can be easily distinguished from other tuna species because of their smaller pectoral fins. They have a pineal window on its head that helps them navigate a wide range of areas. This large fish has a streamlined, torpedo-shaped body that is built for speed and endurance. 

Size 

Atlantic Bluefin Tuna is the largest of its tuna family. Their average size is 6.5 feet in length and 550 pounds, although they can reach twice that size in both weight and length, a whopping 12 feet and 1400 pounds. The Pacific Bluefin Tuna is smaller, with its average size of 5 feet and 130 pounds. 

Interesting Facts 

Bluefin Tuna meat is regarded as the most delicious, particularly among sashimi eaters. Their demand and prices have soared over the last 30 years worldwide, especially in Japan. Commercial operations have found new ways to catch them causing overfishing causing the Bluefin Tuna population to plummet. There are international conservation efforts to save them, but illegal fishing in Europe is endangering this species. 

The Bluefin Tuna hunts fish such as mackerel and herring. They also enjoy invertebrates like crustaceans and squid along with kelp and zooplankton. Their average speed is 43 mph, and they can dive as deep as 3,300 ft. Sharks and whales are occasional predators of young Bluefin Tuna. 

Spawning 

Atlantic Bluefin spawn in the Gulf of Mexico and spawning starts in April and ends in June. Up to ten million eggs are laid, and eggs hatch within 48 hours. They have broadcast spawning habits, which means a few males and females at the same time in the same water release sperms and eggs. This ensures maximum fertilization of eggs. 

Habitat and Distribution 

Bluefin Tuna is native to both the eastern Atlantic and the western Atlantic Ocean. These large fish are a highly migratory species found from New Foundland to the Gulf of Mexico. They are also native to the Mediterranean Sea and were populated in the Black Sea until they were fished to extinction. As they are a rare warm-blooded fish, they comfortably live in cold and tropical water.

Baits and Lures 

If trolling for Bluefin, we suggest using small fish natural bait of herring as your first choice. Squid, mackerel, mullet, or whiting can also be used. If using a line, chumming will attract the tuna and use lures of cedar plugs, spoons, feathers, and poppers. Also helpful to use colors of blue or bone, black or silver. 

Fishing Techniques - How to Catch Bluefin Tuna 

These are strong fish and tough fighters. Be prepared for fast surface runs and deep dives. You will need the heaviest of tackles and a sturdy fishing belt. Some of the most effective techniques include using live bait, trolling with lures, and jigging. Live bait such as squid or mackerel will entice the bluefin tuna to bite, while trolling with lures can mimic the movement of their natural prey. Jigging involves dropping a lure to the bottom of the ocean and quickly reeling it back up, which can trigger the predatory instincts of bluefin tuna.  Trolling is the way to find the school Bluefins as it lets you search and cover large areas. Use of outriggers and your tackle should consist of snap swivels so that anglers can swap the rigs easily. Note, they usually bite more aggressively during the evening and morning hours. Locate them near offshore islands, reefs, or deep-feeding areas. 

Jigging and chunking are two of the most effective and widely-used techniques for catching bluefin tuna. With the ability to target specific depths and locations in the water column, anglers can increase their chances of success in catching these prized fish. However, it is important to note that these techniques require a certain level of skill and experience to execute properly. Furthermore, it is crucial to practice responsible fishing practices to ensure the sustainability of the bluefin tuna population. When implemented responsibly, these techniques can result in thrilling and rewarding experiences for anglers looking to catch the fish of a lifetime.

Bluefin tuna is a type of fish that is considered a delicacy in many parts of the world for its rich and flavorful taste. However, the global population of Bluefin tuna has declined drastically in the past few decades due to overfishing and other environmental factors. This has made it difficult to sustainably harvest this fish, and has also led to concerns about the impact of Bluefin tuna consumption on the environment. Achieving sustainable bluefin tuna conservation means implementing strategies to ensure that bluefin tuna populations will continue to thrive and supply communities with a healthy and delicious source of food. This involves carefully monitoring fishing efforts and adopting fishing methods that minimize harm to the environment and other marine species. There is also a need for strict regulations and policies to prevent overexploitation of bluefin tuna populations. Despite these concerns, many people still enjoy eating Bluefin tuna for its delicious taste, and continue to seek out this fish as a special treat. While it is important to be mindful of the impact of our food choices on the environment, there is no denying that Bluefin tuna is a tasty and sought-after food that many people enjoy.

Yellow Sea Chub

Yellow Sea Chub (Kyphosus incisor) Fish Description

The Yellow Sea Chub (Kyphosus incisor) is a medium-sized fish primarily found in the tropical to subtropical waters of the western Atlantic. The fish has an oblong to an oval compressed body, small head, small mouth with a blunt snout, and weakly forked caudal fin. It has one long and a spiny dorsal fin that runs from the base of the head and ends abruptly before the base of the tail. Even though the fish has a small mouth, it is equipped with strong jaws and sharp, incisor-like teeth. And, as the name suggests, it has alternate blue and yellow longitudinal lines along the sides.    

Diet and Size

Like all members of the Kyphosinae (AKA Rudderfishes) subfamily, the Yellow Sea Chub is omnivorous, which means it can pretty much live off anything it could find in its chosen environments of rocky bottoms and coral reefs. They eat benthic algae, crabs, mollusks, and even feces and vomit from spinner dolphins. And although there were records of the fish reaching thirty-five inches in length, most are just between fifteen and eighteen inches long.

Yellow Sea Chub Interesting Facts

• The largest recorded Yellow Sea Chub measures thirty-five inches long and weighs eight and a half pounds.
• Yellow Sea Chubs are oviparous or they produce their young by means of eggs that are hatched after they have been laid by the parent.
• Yellow Sea Chubs aren’t fished commercially; they are mostly targeted by recreational anglers.
• Their meat is edible but not highly regarded due to its mushy texture and bland taste, not to mention its rather short shelf life.
• They are mostly caught via hook and line, by gill nets, or with spears.

Habitat and Distribution

Yellow Sea Chubs are endemic in the western side of the Atlantic—specifically within subtropical and tropical coastal waters ranging from Cape Cod, Massachusetts in the US to as far south as Brazil. They could also be found in the waters of Gulf of Mexico. 

They mostly stick within shallow waters, especially over rocky bottoms in coral reef areas. They also prefer areas where there are floating Sargassum weeds. 

Yellow Sea Chub Fishing Techniques

Although Yellow Sea Chubs are not really a highly prized fish, catching one can actually still be fun. You can easily catch them near the coasts by drift fishing on rocky bottoms and coral reefs. Also, the fish is quite small and can easily be caught using conventional rods and reels. Just make sure to use a small hook rigged with a tiny piece of fresh bait that would fit its small mouth. The best baits to use are fresh cut strips of fish, crab, or shrimp. You may also employ a bit of chumming (tiny bits of bread will actually be enough) to attract more Yellow Sea Chubs to your fishing spot.
