The bluefin trevally is widely distributed, occupying the tropical and subtropical waters of the Indian and Pacific Oceans, ranging along the coasts of four continents and hundreds of smaller islands and archipelagos. Where the prey is schooling reef fishes, once the prey school has been attacked, the trevally chases down the prey as they scatter back to cover in the corals, often colliding with coral as they attempt to snatch a fish.

A fast growing, species, bluefin trevally mature in 2 years at around 35-40 cm long and 1.2 kg, while 75 cm fish around 10 kg have been aged at 7 years old. Solitary or occasionally in schools. Nutritional Facts by Serving Size: 100g / 3.5oz (raw) Calories Fat Calories Total Fat Saturated Fat Cholesterol Sodium Potassium Protein Omega-3 The fins of juveniles are a pale to dusky blue color and they have yellow pectoral fins. They also are countershaded with a dark dorsal side and a lighter colored ventral side. The pelvic and pectoral fins are white, with the pectoral fin having a yellow tinge. It is usually sold fresh, as well as frozen or salted. These estuaries are often lined by mudflats and mangroves, however the species rarely enters these shallow waters. The size of these fish varies with the geographic region where they are found.The maximum reported length of this species is 1.2 m (3.8 ft) with a maximum weight of 43.5 kg (96 lb). [23], The bluefin trevally is a schooling species as a juvenile, transitioning to a more solitary fish with well defined home ranges as an adult. The 1999 yearbook of the International Game Fish Association has begun arriving in island mailboxes. The species grows to a maximum known length of 117 cm and a weight of 43.5 kg, however is rare above 80 cm. Black spots are found on the adults on the upper areas with the fish developing more spots as they age. It is thought that hybridisation is more likely if one or both parent species is rare in an area, which is the case in much of the Main Hawaiian Islands, where overfishing has severely depleted all trevally species populations. Bluefin trevally also enter lagoons as the tide rises to hunt small baitfish in the shallow confines, leaving as the tide falls. Observations from South African estuaries indicate the schools of smaller juveniles tend not to intermingle with schools of other species, but larger subadults are known to form mixed-species schools with the brassy trevally. [8] The eye is covered by a moderately weakly developed adipose eyelid, and the posterior extremity of the jaw is vertically under or just past the anterior margin of the eye. Trevally Fish Characteristics: Scientific Name: Caranx ignobilis: Other Names: Barrier Trevally, Lowly Trevally: Average Size: Approx 70 cm: Average Weight: up to 5 Kg: Average Life Span: About 35 years: Trevally Fish Size Juveniles lack the blue coloration on their fins and instead have dark… This is a carnivore fish that usually feed the small size fish species in their diet. It tells the tale of a very mystifying case of mistaken identity for what was thought to be the largest bluefin trevally (omilu) ever caught. Commercial fisheries record up to 50 tonnes of the species taken per year in the west Indian Ocean, and around 700 lbs per year in Hawaii. They are opportunistic, voracious, and aggressive predators preying during the day, primarily on fishes such as sardines, anchovies, and small mackerel. The fish move from these shallower inshore waters to deeper reefs as they grow. If a predator is looking down from above, the dark back of the trevally blends in with the dark ocean bottom, but if the predator is looking up from below, the lighter belly of the trevally blends in with the glare of the sun and the light coming from above water. The species' range extends eastwards along the Asian coastline including Pakistan, India and into South East Asia, the Indonesian Archipelago and northern Australia. Juveniles consume a higher amount of small crustaceans, but transfer to a more fish based diet as they grow. This is a stunning fish to view underwater. [17][22] The species appears to have a preference for fish of a specific size, which depends on its own length and age. [39] Spawning events are often clustered in a few consecutive or alternate days, usually in the third or fourth lunar phases. Waiting in ambush to attack prey they can change their coloration to a darker hue. [16], The bluefin trevally occurs in a wide range of inshore and offshore marine settings throughout its range, including estuarine waters. Only the meanest will take fly. [22] Apart from the typical predator-prey relationship the species shows (described later), an individual of the species has been seen to rub itself against the skin of a Galapagos shark, apparently to rid itself of parasites. [19] Otolith data fitted to the von Bertalanffy growth curve shows the species grows to 194 mm in its first year, 340 mm in the second and 456 mm in the third year. [8][11] In the south, the species reaches as far south as Sydney in Australia. [17] In the inshore environment, the species is present in almost all settings including bays, harbours, coral and rocky reefs, lagoons, sand flats and seagrass meadows. The fish living in a particular region congregate in one area at night, before returning to their individual daytime range during the day. [17], The bluefin trevally displays a remarkable array of hunting techniques, ranging from midwater attacks to ambush and taking advantage of larger forage fish. In this case, the parasite invaded the victim's body by entering an open wound while he was filleting the species, and is believed to be one of the first records for such cross contamination. They launch themselves at their intended prey at high speeds and they are also ambush predators, attacking from hiding places. Bluefin trevally eat mainly smaller fish, and occasionally shrimp and crabs. melampygus. The bluefin trevally, Caranx melampygus is also known as the bluefin jack, blue finned crevalle, and in South Africa as the bluefin kingfish. Caranx itself is part of the larger jack and horse mackerel family Carangidae, which in turn is part of the order Carangiformes.[3]. The upper half of the body is grey to brassy in colour with scattered small blue-black spots. [39] The only barrier in these studies to successful production was problems with commercial food items. [19] The diet overlap with the similar C. ignobilis is low in the Hawaiian Islands, suggesting there is some separation of feeding niches. This top eating fish has an average size that will range from 2-4kg and they will put up a powerful fight on lighter gear. They inhabit coastal waters of reefs and rocky islands, peaks of outside outer reefs, channels and lagoons, and open water up to 190 m (623 ft) in depth. The upper body is a brassy color lightening down the body to a silvery white color on the stomach. [31][36], The bluefin trevally reaches sexual maturity at between 30 and 40 cm in length and around 2 years in age,[37] The maximum theoretical size indicated from the growth curves is 89.7 cm, much less than the 117 cm reported as the known maximum size. Growth is well studied, with the fish reaching 194 mm in its first year, 340 mm in the second and 456 mm in the third year. Both were initially identified as hybrids by intermediate physical characteristics, and were later confirmed by DNA sequencing. [13] In Hawaii the species has bag and size limit restrictions in place to prevent further overexploitation. [51], {{cite iucn}}: error: |doi= / |page= mismatch (. While most fish patrol the one reef, some have been observed to make excursions to nearby reefs, before returning to their home reef later. This is a bluefin trevally love story. The average length of a Bluefin Trevally is 60cm and weigh about 3 – 7kg. Sportfishers favor them because of their ability to give a good fight when hooked. Juveniles prefer shallower, protected waters, even entering estuaries for short periods in some locations. Video of Bluefin Trevally (Caranx melampygus) accompanying Smalltooth Emperor (Lethrinus microdon) and Redmouth Grouper (Aethaloperca rogaa) in pack-hunting behaviour in … Their blue color helps them blend in with the clear blue waters of their habitat. [32] Two studies of adult fish in Hawaii found fish to be the dominant food type in the species, making up over 95% volume of the stomach contents by weight. [10] There is no dark spot on the operculum. The study found the fish grew to a commercial size of 300 g in 6 to 8 months and only suffered a 5% mortality rate. [48] The species readily accepts both bait and lures, with live fish or squid often used as bait and a variety of lures also used on the species. [8] In the Indian Ocean, the species easternmost range is the coast of continental Africa, being distributed from the southern tip of South Africa[13] north along the east African coastline to the Red Sea and Persian Gulf. The size of these fish varies with the geographic region where they are found.The maximum reported length of this species is 1.2 m (3.8 ft) with a maximum weight of 43.5 kg (96 lb). Trevallies use camouflage for added protection from predators and to hide from potential prey. DMSP is a naturally occurring chemical produced by marine algae and to a lesser extent coralsand their s… [43] Further investigations into the potential for offshore aquaculture were conducted in Hawaii, where the species successfully spawned in captivity. The names C. bixanthopterus and C. stellatus were often used in the literature, and were variably classed as synonyms of C. melampygus or valid individual species after their naming. The species is most commonly referred to as the 'bluefin trevally', with the species's distinctive blue fins contributing to most of its other common names. [32] Once the prey is close enough to the hiding spot, the fish ram the base of the school, before chasing down individual fish. This species is safe for now. [32] Ambushes have also been observed on small midwater planktivorous fishes are moving to or from the shelter of the reef. Small trevally are edible; however, when they reach a length of about 0.5 m (1.6 ft), they may become toxic and if eaten, may cause ciguatera poisoning in humans. Fishermen love the bluefin trevally for its taste and fighting ability. [42] Also of concern is one report of infection by a dracunculoid parasite while preparing the fish for eating. Body covered with mottled blue specks. And search more of iStock's library of royalty-free stock images that features Animal photos available for quick and easy download. [4] He named the species Caranx melampygus, placing the species in the jack genus Caranx which had been established by Bernard Lacépède three decades previously. The Aquarium of the Pacific’s mission is to instill a sense of wonder, respect, and stewardship for the Pacific Ocean, its inhabitants, and ecosystems. The dorsal fin is in two parts, the first consisting of … [33] They will always fight for their food. [5] This is still currently considered the correct placement, however later authors placed in other now defunct genera (Carangus and Carangichthys) which has since been deemed incorrect, and the original classification stands. The all tackle world record for the species stands at 13.24kg (29lb 3oz) taken off Clipperton Island in 2012. Despite the preference of several families, bluefin trevally do take a very wide variety of fish in small amounts, including various species of eel. 495. More fun to catch? It is similar in shape to a number of other large jacks and trevallies, having an oblong, compressed body with the dorsal profile slightly more convex than the ventral profile, particularly anteriorly. How big. [40] Measurements from juveniles in Hawaii indicate the fish is around 70 mm by 100 days and 130 mm by 200 days. [32] While hunting in midwater, fish swim both against and with the tide, although significantly more fish hunt when swimming with the tide (i.e. They are slightly smaller and has a rounder nose than the regular Trevally. It is a multiple spawner, capable of reproducing up to 8 times per year, releasing up to 6 million eggs per year in captivity. lists as the all-tackle world record a 160-pound, 7-ounce giant trevally caught from a … [47][48] The species inshore habits make it a popular target for spearfishermen also. DMSP is a naturally occurring chemical produced by marine algae and to a lesser extent corals and their symbiotic zooxanthellae. [44] An in vitro cell culture has recently been established for the species, which will allow long term management of potential viral diseases that may arise during aquaculture of the fish. [18] Laboratory tests have confirmed the presence of the toxin in the species flesh,[49] with fish greater than 50 cm likely to be a carrier. They are aggressive fish, sometimes taking food out of the mouths of feeding sharks. The entire body is an iridescent brassy, or gray color of brassy, with blue-black spots scattered on the mid to rear body. Yes, catching this blue gangsters for the flats is much more fun because they are an actively pack hunting fish. [17] There is also a difference in the length at maturation between the two sexes, with females on average reaching maturity at 32.5 cm length, while males attain maturity at 35 cm on average. By using our website, you agree to our cookie policy. The Hawaiian name for this species is omilu. Juveniles lack these obvious colours, and must be identified by more detailed anatomical features such as fin ray and scute counts. Download this Bluefin Trevally Fish photo now. [39] Fecundity in the natural environment has been reported to range from around 50 000 to 4 270 000, with larger individuals releasing more eggs. The species is usually seen singly or occasionally in small schools around coral reefs. The Bluefin Trevally is a large fish, growing to a maximum known length of 117 cm and a weight of 43.5 kg Golden Trevally- Karang Saser Golden Trevally or Karang Saser is a relatively large fish, growing to a maximum recorded size of 120 cm in length and 15.0 kg in weight. [17] Studies in captive fish show females may produce over 6 000 000 eggs per year. This slight convexity leads to the species having a much more pointed snout than most other members of Caranx. Habitat. Average fish are on the smaller side of the Jack/Trevally spectrum, with most caught up to 20lbs, but rarely over 12lbs. They will eat anything that is not to large for them too swallow. Largest Size. [17] The period of the year over which spawning occurs is also variable by location, with African fish reproducing between September and March[37] while in Hawaii this occurs between April and November, with a peak in May to July. Welcome! [26] The number of fish present in an area is also influenced by tidal factors and possibly the abundance of prey and other environmental factors. There is evidence the species is only resident in these estuaries for short periods. The current IGFA All-Tackle Record for giant trevally stands at 160lbs for a specimen caught in Kagoshima, Japan. [29] A study on carangids caught during a fishing tournament in Hawaii found the bluefin trevally is the most common trevally species taken, accounting for over 80% of the carangid catch. The trevallies were purchased from a local fisherman and were held in captivity for 6 months prior to the experiment. [27] Long term studies have found the fish may range up to 10.2 km over several months, however, is much less restricted in its movements than its relative, the giant trevally. Adults do school to form spawning aggregations or temporarily while hunting, with evidence from laboratory studies indicates bluefin trevally are able to coordinate these aggregations over coral reefs based on the release of dimethylsulfoniopropionate (DMSP) from the reef. Bluefin Trevally can grow up to almost 4ft in length and 100lbs in weight, however, giants like that haven't been officially recorded. [34] In some cases, only one individual in a group will attack the prey school. [7] Under ICZN nomenclature rules, these later names are deemed junior synonyms of C. melampygus and rendered invalid. They are also found in waters around islands off East Africa. Reels Bonefish and Trevally reels rigged with floating lines Offshore reel rigged with intermediate full sinking line. Although they are usually solitary animals, they can be found in pairs or small groups. The bluefin trevally inhabits both inshore environments such as bays, lagoons and shallow reefs, as well as deeper offshore reefs, atolls and bomboras. [2] Juveniles often enter estuaries, however the species is not estuary dependent as breeding is known to occur where no estuaries are present, suggesting the use of these habitats is facultative. Small fish are able to effectively filter these small crustaceans from the water, while adults are not. Photo taken at the Aquarium's Soft Coral Reef Aquarium of the Pacific, Juvenile bluefin trevally NW Hawaiian Islands. The largest specimens reach about 39”/100 cm, but most average 23-27”/60-70cm. The species is known to move throughout the water column; however is most often observed in a demersal setting, swimming not far from the seabed. [12] The upper jaw contains a series of strong outer canines with an inner band of smaller teeth, while the lower jaw contains a single row of widely spaced conical teeth. This slight convexity leads to the species having a much more pointed snout than most other members of Caranx. [11] The caudal fin is strongly forked, and the pectoral fins are falcate, being longer than the length of the head. After they reach lengths greater than 16 cm, blue-black spots appear on the upper flanks of the fish, with these becoming more prolific with age. [17] The maximum theoretical size indicated from the growth curves is 89.7 cm,[17] much less than the 117 cm reported as the known maximum size. [45] The bluefin trevally has been successfully kept in large saltwater aquaria, but require large water volumes to adapt well. Adult bluefin trevally are both coastal and pelagic fish. Dateline June, 1999. [8] It is similar in shape to a number of other large jacks and trevallies, having an oblong, compressed body with the dorsal profile slightly more convex than the ventral profile, particularly anteriorly. The bluefin trevally is a large fish, growing to a maximum known length of 117 cm and a weight of 43.5 kg, however it is rare at lengths greater than 80 cm. [17] Calculations suggest each individual bluefin trevally consumes around 45 kg of fish per year on average, making it one of the most effective predators in this habitat. [42] In Hawaii, the nearshore stocks of the species have been in decline since the early 1900s, with commercial landings dropping over 300% from 1990 to 1991, and have not recovered. Leaders Bonefish: 10 … your username. [42] It is considered to be a good to excellent food fish, however many cases of ciguatera poisoning have been attributed to the bluefin trevally. [24] In both cases, a transition to a more fish based diet with age was found to occur, although the length at which this transition occurred varied between location. Dorsal, anal and tail fins electric blue in colour in adult fish. It reaches 75 cm by 8 years of age and 85 cm by 12 years. Females are multiple spawners laying eggs as often as every five days. The species' aquaculture potential was first investigated in a 1975 experiment in French Polynesia, where juveniles of the species were caught in the wild and transported back to a laboratory. [50] The IGFA maintains full line and ripped class records for the bluefin trevally. [2] The southernmost record from the west coast of Australia comes from Exmouth Gulf. The bluefin trevally is a schooling species as a juvenile, transitioning to a more solitary fish with well defined home ranges as an adult. Found singly or in schools patrolling reef slopes over coastal and oceanic reefs. [24] The species is also absent from coastal lakes that many other carangids are known from. 100 Aquarium Way, [2] Its offshore range does extend north to Hong Kong, Taiwan and southern Japan in the north western Pacific. Log into your account. The species grows to a maximum known length of 117 cm and a weight of 43.5 kg, however is rare above 80 cm. Juveniles and subadults are more common in these settings, and prefer these more protected environments, where they live in water to a minimum of around 2 m depth. The rapid decimation of the Hawaiian population due to overfishing has led to increased research in the aquaculture potential of the species, with spawning achieved in captivity. [17] Sex ratios in the species vary by location with population off east Africa being skewed towards males (M:F = 1.68:1),[37] while in Hawaii the opposite is true with the M:F ratio being 1:1.48. Bluefin Trevally may not be the biggest member of the family, but they’re definitely the prettiest. A large trevally with a tapered snout, electric blue second dorsal, anal and caudal fins and numerous blue and black spots on the sides. [22], Juvenile and subadult bluefin trevally have been recorded in estuaries in several locations,[19] and generally occupy large, open estuaries up to the middle reaches of the system. (2019). [6] The species was independently redescribed and named seven times after Cuvier's initial description, with all of these names assigned between 1836 and 1895. Founded in June 1998, the Aquarium of the Pacific is a 501©3 non-profit organization. Giant Trevally: 10 or 11-weight. [39] The species is taken by a variety of netting and trapping methods, as well and by hook and line in commercial fisheries. The Bluefin Trevally can be recognised by the electric blue colour of the second dorsal, caudal and anal fins. [40] Digestive enzymes active from hatching to 30 days old show an apparent shift from carbohydrate utilisation to protein and lipid utilisation as the larvae grows older. External fertilization occurs in the open ocean usually from May to August. Bluefin trevally are easily recognised by their electric blue fins, tapered snout and numerous blue and black spots on their sides. [18] The bluefin trevally displays some habitat partitioning with giant trevally, Caranx ignobilis, tending to be more common outside the major bays than their relatives. [8] Despite their wide range, the only geographical variation in the species is the depth of the body in smaller specimens. [17] Natural spawning behaviour in the species has never been observed,[38] although large aggregations of bluefin trevally observed in Palau consisting of over 1000 fish are believed to be for the purpose of spawning. 'downstream'), suggesting some mechanical advantage is gained when hunting in this mode. The authors note that this may not only reflect its abundance, but also it vulnerability to specific fishing methods used in the tournament. Bluefin jack is the most common jack on Maldivian reefs. The reason for this congregation is unclear, but may be important to the social structure of the species. Evidence in Hawaii has shown that a GT can mate with bluefin trevally after an impressive 88lb bluefin was captured. )", "Contrasts in density, size, and biomass of reef fishes between the northwestern and the main Hawaiian islands: the effects of fishing down apex predators", "Feeding Relationships of Teleostean Fishes on Coral Reefs in Kona, Hawaii", "Indigenous ecological knowledge and its role in fisheries research design: A case study from Roviana Lagoon, Western Province, Solomon Islands", "Two hybrids of carangid fishes of the genus, "Evaluation of the status of the recreational fishery for ulua in Hawai'i, and recommendations for future management", "First Experiments on the Rearing of Tropical Carangidae in Floating Cages", "Establishment and characterization of two cell lines from bluefin trevally, "A review of the movements of fish held in captivity in the Reunion Island Aquarium over a five-year period", https://en.wikipedia.org/w/index.php?title=Bluefin_trevally&oldid=1000639832, Creative Commons Attribution-ShareAlike License, Approximate range of the bluefin trevally, This page was last edited on 16 January 2021, at 01:00. The bluefin trevally is distributed throughout the tropical waters of the Indian and Pacific Oceans, ranging from Eastern Africa in the west to Central America in the east, including Japan in the north and Australia in the south. The bluefin trevally is a large fish, growing to a maximum known length of 117 cm and a weight of 43.5 kg, however it is rare at lengths greater than 80 cm. This behaviour is also observed in rainbow runner and is a rare example of a commensal cleaner relationship where the cleaner does not gain anything. The species is easily distinguishable by their electric blue fins, which in real life are more vibrant than in the photographs. The Bluefin Trevally is found in the Eastern Central Pacific, Indo-Pacific region growing up to 70cm in length. The giant trevally is a solitary fish once it reaches sexual maturity, only schooling for the purposes of reproduction and more rarely for feeding. [25] Adults do school to form spawning aggregations or temporarily while hunting, with evidence from laboratory studies indicates bluefin trevally are able to coordinate these aggregations over coral reefs based on the release of dimethylsulfoniopropionate (DMSP) from the reef. (562) 590-3100. [7], The upper body of the bluefin trevally is a silver-brassy colour, fading to silvery white on the underside of the fish, often with blue hues. Spawning apparently occurs at night to minimise predation on eggs. GTs have been known to follow monk seals and sharks when hunting, feeding on ‘forgotten’ prey. Also known as the Blue Jack Fish. Most trevallly are smaller. The catch statistics for the bluefin trevally are poorly reported in most of its range, with only parts of the western Indian Ocean supplying information to the FAO. Usually solitary, they may also be found in small groups in shallow coastal water and in deep, open ocean habitats. Despite its popularity as a table fish, many cases of ciguatera poisoning have been reported from the species. [18] Extensive studies on the species in captivity has revealed the species to be a multiple spawner, capable of spawning at least 8 times a year, and up to twice in 5 days. Juveniles and subadults commonly school, both in marine and estuarine environments. [14] Its distribution continues throughout the western Pacific including Tonga, Western Samoa and Polynesia, and the Hawaiian Islands.
