However, if you do wish to catch an Oscar in the wild, the Amazon River Basin and its tributaries should be your first port of call. In the United States, established populations have been identified in Florida and other southern states.
How to Catch
Oscar Fish are aggressive feeders, and are therefore relatively easy to catch. Preferred bait includes earthworms, crickets, and even small fish. Anglers typically use light to medium tackle when fishing for Oscars. They may also bite on lures if they are presented aggressively enough.
