KERAPU
Ikan kerapu dalam bahasa latin merupakan ikan yang memiliki banyak saudara dan berada dalam subfamily Epinephelinae, ikan kerapu sebenarnya terdiri dalam beberapa spesies, namun karena umumnya bentuknya hampir sama hampir tidak bisa dibedakan jenis spesiesnya apalagi saat dipancing. Perbedaan dari setiap spesies mungkin hanya dari warnanya saja dan beberapa corak tubuh saja.
Ikan kerapu memiliki bentuk tubuh yang gelap dengan totol diseluruh tubuh, ikan ini menggunakan totol tubuhnya sebagai kamuflase atau tipuan pada saat ia berburu makanannya. Ikan kerapu merupakan ikan karang dan jarang sekali berenang jauh, ikan kerapu di perairan karang makan ikan, gurita, kepiting dan lobster. Cara makan ikan ini cukup unik yakni dengan menunggu mangsanya mendekat dengan penyamaran kamuflase yang tepat. Dan setelah mangsanya mendekat ia akan menyedot mangsa tersebut dengan kekuatan mulutnya yang rahangnya besar, ikan kerapu memakan utuh ikan yang menjadi makanannya dan tidak mencabiknya. Dalam berburu ikan jarang sekali ikan ini berenang dengan cepat untuk menangkap mangsanya, ia hanya menunggu mangsanya mendekat untuk memakannya.

MANGROVE JACK
Commonly called Mangrove Jack within Australia, the Mangrove red snapper (Lutjanus argentimaculatus) is an explosive and powerful sport fish that is renowned for its superb eating and fighting qualities.
Coloration of the Mangrove Jack ranges from burnt orange, to copper, to bronze and dark reddish-brown, depending on its age and environment. Younger fish caught in estuarine areas are often darker than older fish taken from offshore reef areas,[1] and exhibit lighter vertical bands down their flanks.

Lutjanus argentimaculatus is found in the Indo-Pacific region from Australia in the south to Japan in the north, and as far west as the eastern coast of Africa.[2] Distribution within Australia is largely centered on the northern half of Australia, spreading from northern New South Wales into northern Western Australia.

As its name implies, the Mangrove Jack is commonly found in mangrove-lined estuarine systems although is known to migrate to offshore reefs in order to spawn. As ambush predators, `Jacks' often dwell around mangrove roots, fallen trees, rock walls, and any other snag areas where smaller prey reside for protection. For fishermen, the telltale sign of a hooked Mangrove Jack is the explosive run for cover once the bait (or lure) is taken. Many fish (and again, lures) are lost once they reach the protection of the snags as a result of their initial burst of speed. As they mature, Mangrove Jacks move into open waters, sometimes hundreds of kilometers from the coast[3] in order to breed. These larger fish are sometimes caught by bottom-fishers with heavy tackle, though they still remain difficult to land due to their speed and proximity to sharp reef bottoms.

The Mangrove Jack is a highly regarded table fish with firm, sweet tasting, white flesh. While often a nuisance species when targeting the infamous Barramundi, many fisherman rate the eating qualities of the Jack higher than its more famous neighbour. In reef areas, Mangrove Jack are sometimes confused with red bass (Lutjanus bohar), a known carrier of Ciguatera toxin. They are however easily distinguishable by the large deep pit in front of the eyes of the red bass.




GIANT TREVALLY
The giant trevally, Caranx ignobilis (also known as the giant kingfish, lowly trevally, barrier trevally, ulua, or GT), is a species of large marine fish classified in the jack family, Carangidae. The giant trevally is distributed throughout the tropical waters of the Indo-Pacific region, with a range stretching from South Africa in the west to Hawaii in the east, including Japan in the north and Australia in the south. The giant trevally is distinguished by its steep head profile, strong tail scutes and a variety of other more detailed anatomical features. It is normally a silvery colour with occasional dark spots, however males may be black once they mature. It is the largest fish in the genus Caranx, growing to a maximum known size of 170 cm and a weight of 80 kg. The giant trevally inhabits a wide range of marine environments, from estuaries, shallow bays and lagoons as a juvenile to deeper reefs, offshore atolls and large embayments as an adult. Juveniles of the species are known to live in waters of very low salinity such as coastal lakes and upper reaches of rivers, and tend to prefer turbid waters.
The giant trevally is a powerful apex predator in most of its habitats, and is known to hunt individually and in schools. The species predominantly takes various fish as prey, although crustaceans, cephalopods and molluscs make up a considerable part of the diet in some regions. The species has some quite novel hunting strategies including following monk seals and stealing prey that is stirred up, as well as using sharks to ambush prey. The species reproduces in the warmer months, with peaks differing by region. Spawning occurs at specific stages of the lunar cycle, when large schools of giant trevally congregate to spawn over reefs and bays, with reproductive behaviour observed in the wild. The fish grows relatively fast, reaching sexual maturity at a length of around 60 cm at 3 years of age. The giant trevally is both an important species to commercial fisheries and a recognised gamefish, with the species taken by nets and lines by professionals and by bait and lures by anglers. Catch statistics in the Asian region show hauls of 4000-10 000 tonnes, while around 10 000 lbs of the species is taken in Hawaii each year. The species is considered poor to excellent table fare by different authors, although ciguatera poisoning is common in the fish. Dwindling numbers around the main Hawaiian Islands have also led to several proposals to reduce the catch of fish in this region.
