TREVALLY, BIG EYE
The Bigeye Trevally, is a species of widespread large marine fish classified in the jack family Carangidae. The species is known to grow to a length of 120 cm and 18 kg. The fish is known to move from a more crustacean dominated diet as a juvenile to a nearly completely fish dominated diet as an adult. Sexual maturity is reached at 42 cm, with spawning occurring in large aggregations occurring at different periods throughout its range, generally between July and March. The Bigeye Trevally is of moderate importance to fisheries throughout its range, and being of high importance to some artisanal fisheries.
It is similar to most other trevallys or jacks in having a compressed, oblong body, with the dorsal profile slightly more convex than the ventral profile, particularly anteriorly. The snout is slightly pointed, and is greater in length than the eye diameter. The dorsal fin is in two distinct sections; the first consisting of 8 spine and the second of 1 spine and 19 to 22 soft rays. The anal fin consists of 2 anteriorly detached spines followed by 1 spine and 14 to 17 soft rays. The pelvic fins consists of 1 spine and 17 to 18 soft rays, while the caudal fin is strongly forked and the pectoral fin falcate. The species lateral line is moderately arched anteriorly, with 49 to 50 scales in this section, while the straight section contains 0 to 3 scales and 27 to 36 strong scutes. The breast is completely covered in scales. The species has well-developed adipose eyelids, while its dentition consists of an outer row of widely spaced canine teeth and an inner band of villiform teeth in the upper jaw, with a row of widely spaced conical teeth on the lower jaw. The bigeye trevally has 21 to 25 gill rakers and 25 vertebrae.
Bigeye Trevally will take most lures, but metals like the 20gram twistie and 40gram raider will take most fish. They will also quite happily take poppers such as the Tackle House feed popper 100, the 90mm Skitter Pop or the zipbaits ZBL popper. Minnows are also used as well such as the Rapala X-Rap and megabass vision 110 (or like). Vibs such as the Zipvib 80 and Eclipse heavy slight 90 also work well when dropped down to the bottom around current lines. You can use plastics as well but they seem to be not as consistent.
The Bigeye Trevally is widely distributed throughout the tropical and subtropical waters of both the Indian and Pacific Oceans. 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. Its range extends east along India, South East Asia, Indonesia and many offshore Indian Ocean islands. The range extends north to Japan and south to Australia in this central Indo-pacific region. In the Pacific Ocean, the Bigeye Trevally inhabits most of the tropical island groups including Hawaii, with its range extending east to the western American coastline. In this eastern region of its distribution it has been recorded from the American state of California in the north, including the Gulf of California, and south to Ecuador and the Galapagos Islands.
In Australia it is known from the south-western coast of Western Australia, around the tropical north and south to the central coast of New South Wales.
