There are no "seasons" on fish in Arkansas, just size & number limits. Like the rainbow trout...six fish or less is the limit with no size limitations but there is a size slot limit on the german brown trout; if I remember right I think it's 15". All this depends on the body of water you're fishing in too, some lakes have size limits & others don't & some of the ones that do have different size limits from others that do; I.E. what's legal to keep from one body of water may not be legal to keep from another. It sounds strange to hear the term "trout season" being from Arkansas.
