Whitefish and vendace are the most common fish species in Lake Inari, the latter having been accidentally naturalized. Lake trout can be caught in creeks. Other fish found in the park include Arctic char, grayling, pike, perch, burbot, three-spined stickleback, ninespine stickleback and minnow. Stocking with fish has resulted in the introduction of Atlantic salmon, vendace and lake trout.
