It is also easily attracted to artificial reefs, where studies have found it to be one of the predominant species around these structures in Taiwan. The giant trevally is considered one of the top gamefish of the Indo-Pacific region, having outstanding strength, speed and endurance once hooked. Larvae appear to also opportunistically feed on small zooplankton while swimming. Each individual appears to spawn more than once in each period, with only part of the gonads ripe in spawners. But unlike Mr. T's jewelry, the GT's physique isn't just for show. Known to anglers as the "GT," the giant trevally ranges in color from silver to jet black and grows to as much as 5.5 feet long and 175 pounds. In some of these locations, such as Australia, it is a common and relatively abundant inhabitant, while in others, including South Africa and Hawaii, it is much rarer in estuaries. Sharks are beautiful”, as she was was being wheeled to the hospital after landing in the rescue helicopter. One thing everyone loves about the GT’s is their fighting powers. The eye is covered by a moderately well-developed adipose eyelid, and the posterior extremity of the jaw is vertically under or just past the posterior margin of the pupil. This is believed to allow the fish to gain a panoramic view of its surroundings, removing the need to constantly move the eye, which in turn will allow easier of detection of prey or predators in that field of view.

This number is considerably less in heavily fished Hawaiian waters. Eggs are described as pelagic and transparent in nature. 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 conical teeth. Long-term studies show juveniles can move up to 70 km away from their protected habitats to outer reefs and atolls. Think of the giant trevally as the Mr. T of the oceans, a burly, aquatic intimidator, that's so voracious and powerful, it doesn't have anything to fear besides sharks and humans. The giant trevally is abundant in the central Indo-Pacific region, found throughout all the archipelagos and offshore islands including Indonesia, Philippines and Solomon Islands. However, fish of this length can vary in weight by as much as 20lb. There are many mentions of ulua in Hawaiian proverbs, all generally relating to the strength and warrior-like qualities of the fish. If you’re looking for a scary Halloween costume at the last minute, BBC Earth’s Blue Planet II just provided a good idea for you: a giant trevally. Eventual photos shown in this page may or may not be from Wikipedia, please see the license details for photos in photo by-lines. Length at the age of one year is 18 cm, at two years is 35 cm and by three years, the fish is around 50 to 60 cm. But catches have declined by 84 percent in the course of the last century, which implies the population is only getting smaller. The opportunistic nature of giant trevally has also been made evident by studies on the mortality rate of undersized or egg-bearing lobsters released from traps at the water's surface of the Hawaiian Islands. The leading edges and tips of the anal and dorsal fins are generally lighter in colour than the main part of the fins. Dwindling numbers around the main Hawaiian Islands have also led to several proposals to reduce the catch of fish in this region. Research has been conducted on the movements of larger fish around their habitats, as well as the movement between habitats as the species grows, to understand how marine reserves impact on the species. Lunar cycles are also known to control the spawning events, with large schools forming in certain locations at specific phases of the moon in Hawaii and the Solomon Islands. Juvenile turtles and dolphins were reported being found within the stomach contents of larger giant trevally. The GT will eat just about any small fish found in tropical waters, but it's particularly partial to species of fusiliers from the Lutjanidae family. The curved section of the lateral line contains 58-64 scales, while the straight section contains none to four scales and 26 to 38 very strong scutes. The giant trevally is a solitary fish once it reaches sexual maturity, only schooling for the purposes of reproduction and more rarely for feeding. Our range maps are based on limited data we have collected. After Forsskål's initial description and naming, the species was independently renamed three times as Caranx lessonii, Caranx ekala and Carangus hippoides, all of which are now considered invalid junior synonyms. You're also going to need a rugged spin stick that can put the brakes on quickly, or else it's likely to snap like a twig. The dorsal fin is in two parts, the first consisting of eight spines and the second of one spine followed by 18 to 21 soft rays. Studies in controlled environments on the giant trevally's feeding strategies have found hunting in schools increases their capture efficiency, but is not necessary for an individual's survival. Caranx itself is part of the larger jack and horse mackerel family Carangidae, a group of percoid fishes in the order Perciformes. Juveniles and subadults commonly school, both in marine and estuarine environments. Copyright © 2021 Discovery Communications, LLC. The species predominantly takes various fish as prey, although crustaceans, cephalopods and molluscs make up a considerable part of their diets in some regions. The species is also popular with spearfishermen throughout its range. You are NOT in control and you are not going to land that fish in 20 minutes. Giant trevally also feed on fledgling sooty terns on Farquhar Atoll snatching them from the water surface and even jumping acrobatically to catch them in the air as seen on the BBC documentary Blue Planet II, episode 1. The species has also successfully been bred for aquaculture purposes in Taiwan. Talk about a feeding frenzy! Please post your images to our Thai Biodiversity Survey & Species ID group on Facebook.

Binomial name: Caranx ignobilis, Peter Forsskål, 1775. As previously mentioned, as the giant trevally grows, it shifts from turbid inshore waters or estuaries to reefs and lagoons in bays, moving finally to outer reefs and atolls. The giant trevally (Caranx ignobilis), also known as the lowly trevally, barrier trevally, giant kingfish or ulua, is a species of large marine fish classified in the jack family, Carangidae. Giant trevally gathered in schools of over 100 individuals, although ripe individuals occurred slightly deeper; around 2–3 m above the seabed in groups of three or four, with one silver female being chased by several black males. It's even been known to eat juvenile turtles and dolphins. Spawning occurs during the warmer months in most locations, although the exact dates differ by location. Some recreational fishing groups are also promoting a catch and release practice for the giant trevally, with this becoming an increasingly popular option for charter boat operators, who have also begun to tag giant trevally for scientific purposes. He named the species Caranx melampygus, placing the speci… Despite this, populations have decreased, and in light of their continued falling abundance in Hawaii, several recommendations, including banning the commercial take of the species, increasing minimum lengths and decreasing bag limits for anglers, as well as reassessment of protected areas for the species, have been proposed by officials. These observations suggest the species becomes an effective swimmer (is able to swim against a current) around 7–14 mm. GTs will even attack and eat smaller members of its own species. After 4 days you know when you hook a giant. The use of von Bertalanffy growth curves fitted to observed otolith data show an individual of around 1 m in length is about eight years old, while a 1.7 m fish would be around 24 years old. Also, learn the most dangerous fishing waters around the world. This fish is a powerful swimmer, capable of handling the strong currents in deepwater environments and the pounding swells along the edges of reefs. The giant trevally is an apex predator in most of its habitats, and is known to hunt individually and in schools. No problem if you do not know the species, we will do our best to identify it for you. Giant Trevally has become hugely popular for both lure and fly anglers. Please help us improving our species range maps. The species' edibility has been rated from poor to excellent by different authors, although numerous cases of ciguatera poisoning have been reported from the species. In fact, after we posted it a few people made comments saying there was no way the GT were moving that fast in the shallow water (but it … The giant trevally was first scientifically described by the Swedish naturalist Peter Forsskål in 1775 based on specimens taken from the Red Sea off both Yemen and Saudi Arabia, with one of these designated to be the holotype. The species has a wide salinity tolerance, as evident from the ranges from which juvenile and subadult fish in South African estuaries have been recorded; 0.5 to 38 parts per thousand (ppt), with other studies also showing tolerance levels of less than 1 ppt. Name: Giant Trevally HNI 0036 giant trevally.jpg Value: 4,500 Location: Tropical Island Shadow: Very Long Size Range: 69.70 in - Mr Phillips said both fish were known to attack humans, and giant trevally bites were capable of causing fractures. Think of the giant trevally as the Mr. T of the oceans, a burly, aquatic intimidator, that's so voracious and powerful, it doesn't have anything to fear besides sharks and humans. Giant Trevally, Bonefish, Giant Trevally, Permit, Triggerfish, Astove for many was the pinnacle atoll of the original Assumption, Cosmoledo, Astove mother boat accessed fishing program. The speed at which larvae swim increases with age from 12 cm/s at 8 mm in length to 40 cm/s at 16.5 mm, with size rather than age a better predictor of this parameter.
