- "I caught a giant trevally! Pfff. I've seen bigger!"
An information board in the aquarium will provide information about this fish.
"Though you wouldn't guess it because of their size, giant trevallies are actually a type of mackerel. Unlike normally slim and sleek mackerels, giant trevallies have wide, silver bodies. Surprisingly, though, these fish cannot tolerate the cold, so they tend to live in warmer places. Their jaw strength is great enough to bite off a person's finger, so be very careful when fishing for them!"
In real life
The Giant Trevally, also known as the Giant Kingfish, Lowly Trevally, Barrier Trevally, Ulua, or GT, is distributed throughout the tropical waters of the Indo-Pacific region, ranging from South Africa to Hawaii, including Japan and Australia. They have been recorded to grow as large as 170cm (or 5'7") and weighing as much as 80kg (roughly 175lb). The Giant Trevally will inhabit a wide range of environments, from estuaries, shallow bays, and lagoons as a juvenile to deeper reefs, offeshore atolls, and large embayments as an adult. Young Trevally are known to live in waters with very low salinity such as coastal lakes and upstream in rivers.
The species mainly preys on crustaceans, cephalopods, and molluscs. They have some interesting hunting strategies, such as shadowing monk seals to pick off escaping prey, and using sharks to ambush prey. Spawning occurs at specific stages of the lunar cycle, when large schools come together over reefs and bays. They reach full maturity at around three years.
Giant Trevally is considered poor to excellent table fare by different authors, although ciguatera poisoning is common in this fish. This has led to a decline in their numbers around inhabited regions such as Hawaii.
