Oscar

No minimum size limit. No bag limit. No closed season. It is illegal to introduce any nonnative fish or any other nonnative organism into the waters of the state. No live nonnative fish, except variable platys and fathead minnows (aka Missouri minnows), may be transported to or between waters for use as bait. Catch an oscar over 1.25-pounds, and you qualify for the Big Catch Angler Recognition Program, which rewards anglers who catch a memorable-sized fish.
