The Fish Set is a furniture in Animal Crossing: New Leaf that is obtained from Chip during the Fishing Tourney. Despite containing traditional furniture items such as lamps and tables, it is classified in-game as a set rather than a series. The entire Fish Set cannot be ordered from the catalog, although it can be viewed.
If the player gives Chip an entry that breaks the first-place record during any fishing tourney, and the entry is above average size for that particular type of fish, then he will reward the player with a Fish Set item. However, if the fish is a record-breaker but at or below the average size for that type of fish, he will simply give the player a regular furniture item instead.
