Giant trevally

The giant trevally is a fish you catch off the pier. Look for a very large shadow. In the northern hemisphere look for it in May – Oct, at any time of day. It can only appear after you have caught 20 fish. Nook's Cranny pays 4,500 Bells, C.J. pays 6,750 Bells.

Cast from the pier at X-Large shadows after 20 catches; it never appears anywhere else. Sea bass often show up as big shadows there too, but this one is worth 4,500 Bells.
