[23][24] Older individuals tend to move to deeper seaward reefs, bomboras and drop-offs away from the protection of fringing reefs, often to depths greater than 80 m.[25][26] Large individuals, however, often return to these shallower waters as they patrol their ranges, often to hunt or reproduce.

Its distribution continues throughout the western Pacific, including Tonga, Western Samoa and Polynesia, with its easternmost limits known to be the Pitcairn and Hawaiian Islands. Froese, Rainer and Pauly, Daniel, eds. 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 authors argued, based on this test, the flesh of giant trevally was safe to consume. In the Indian Ocean, it ranges from South Africa and Madagascar in the west, along the east African coastline up to both the Red Sea and Persian Gulf. These young fish eventually move to inshore reefs as they mature, before again moving to deeper outer reefs. The species is most common in shallow coastal waters in a number of environments, including coral and rocky reefs and shorefaces, lagoons, embayments, tidal flats and channels. [48] So far this behaviour has not been observed elsewhere. [6] In the Philippines, the species is referred to as talakitok. Silver trevally occur in estuarine and coastal waters of southern Australian states ranging from about Coffs Harbour in NSW to about Perth in WA. The seal does not appear to gain any benefit from this relationship, and it is thought juvenile seals being followed in this way may be outcompeted by the larger fish. [58] In recent years, the development of both jigging and surface-popping techniques has seen the giant trevally become an extremely popular candidate for catch and release fishing,[10] with many charter operators based around this concept. [6] In Hawaii, the species is almost exclusively referred to as ulua, often in conjunction with the prefixes black, white, or giant. A rare opportunity to secure one of the best homes South Hedland has to offer! Larvae have no association with reefs, and appear to prefer to live pelagically. The species is considered poor to excellent table fare by different authors, although ciguatera poisoning is common from eating the fish. It is the largest species of trevally in Australian waters. Trevally Fish. Giant trevally (Caranx ignobilis) is also known as giant kingfish, barrier trevally, lowly trevally, ulua (in Hawaii) or GT for short. Hawaii has the best-kept statistics, where the 1998 catch consisted of 10,194 pounds of giant trevally worth around US$12,000. [25] Daily growth is estimated at between 3.82 and 20.87 g/day, with larger fish growing at a more rapid rate. The ulua, as the fish is known to Hawaiians, was likened to a fine man and strong warrior, which was the cause of a ban on women eating the species in antiquity. [12] The eye of the giant trevally has a horizontal streak in which ganglion and photoreceptor cell densities are markedly greater than the rest of the eye. This cottage offers an outdoor pool, a picnic area, and a … The lateral line has a pronounced and moderately long anterior arch, with the curved section intersecting the straight section below the lobe of the second dorsal fin. Rarely, they have been recorded behaving in the same way towards humans: A spearfisher in Hawaii broke three ribs when rammed by a giant trevally. 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. [25] Size is also a better predictor of endurance in larvae than age. Description of the biology and an assessment of the fishery for silver trevally Pseudocaranx dentex off New South Wales, Final Report to Fisheries Research and Development Corporation, Project 97/125, NSW Fisheries Final Report Series No. 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. Spawning occurs at specific stages of the lunar cycle, when large schools congregate to spawn over reefs and bays, with reproductive behaviour observed in the wild. Some success has been achieved in raising giant trevally commercially in small fish farms there, typically to an age of seven months. Its range extends east along India, South East Asia, Indonesia and many offshore Indian Ocean islands. 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. [26][38] Locations for spawning include reefs, the reef channels and offshore banks. However, analysis of case studies in which ciguatera poisoning was reported after eating the fish suggested an accumulative effect occurs with repeated consumption; and tests like the one outlined above are not reliable, as the toxin appears to be distributed haphazardly throughout each fish. [27] 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. No obvious relationships with age and either swimming depth or trajectory have been found. 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. Species such as Silver Trevally can be found in large schools in … [14] The pelvic fins contain 1 spine and 19 to 21 soft rays. The only time hunting in schools is a disadvantage is when only isolated prey are present, such as close to a reef; here, an individual hunter has a greater probability of capturing it than if a group is present. The trevally swim close by the seal, and when the seal stops to forage, the trevally positions its mouth inches away from the seal. The larvae actively avoid other large fish, and jellyfish are occasionally used as temporary cover. [11][16], The giant trevally inhabits a very wide range of offshore and inshore marine environments, with the species also known to tolerate the low salinity waters of estuaries and rivers.

The specimen was initially thought to be a bluefin trevally of world-record size, but was later rejected when it was discovered to be a hybrid. A group of 8 headed off to South Australia to join the MV Rodney Fox ... the water was dirty with burley and there were constant schools of trevally in the bloody way but between us we got worthwhile stuff. A hybrid of C. ignobilis and C. melampygus (bluefin trevally) has been recorded from Hawaii.

The species more common in NSW include the Silver Trevally, Bluefin Trevally and Bigeye Trevally. [52], The giant trevally's early larval stages and their behaviour have been extensively described, with all fins having formed by at least 8 mm in length, with larvae and subjuveniles being silver with six dark vertical bars. [18] Individuals with darker dorsal colouration often also display striking silvery striations and markings on the upper part of their bodies, particularly their backs. It includes a kitchen and 3 bedrooms. The Giant Trevally can be recognised by its steep head profile, strong scutes on the straight, posterior portion of the lateral line and its large size. [27], In the Philippines, a population of giant trevally inhabit (and were once common in) the landlocked fresh waters of the formerly saltwater Taal Lake, and are referred to as maliputo to distinguish them from the marine variant (locally named talakitok). [12], The giant trevally is considered one of the top gamefish of the Indo-Pacific region, having outstanding strength, speed and endurance once hooked. The chest is devoid of scales with the exception of a small patch of scales in front of the pelvic fins. [17], At sizes less than 50 cm, the giant trevally is a silvery-grey fish, with the head and upper body slightly darker in both sexes. [37], The giant trevally is a solitary fish once it reaches sexual maturity,[20] only schooling for the purposes of reproduction and more rarely for feeding. Minimum legal length: 24 cm; Personal daily bag limit: 20; Daily boat limit when 3 or more people are fishing on board: 60 It is normally a silvery colour with occasional dark spots, but males may be black once they mature. trevally in south-eastern Australian and northern New Zealand waters is distinct from the larger tropical form (Pseudocaranx dentex) and the old name (P. georgianus) has been restored.
