Abstract: The annual production of the creek chub, Semotilus atromaculatus, and southern redbelly dace, Phoxinus erytbrogaster, was measured in a small headwater stream in southeastern Ohio. Creek chub annual production was 13.60 g • m~2 per yr, and P/B was 1.16. Dace annual production was 2.77 g • m~2 and P/B was 1.82. Even though the stream was acidic (pH 6.3) and infertile, fish production compared favorably with that of small alkaline streams. Considerable production within allochthonous food chains probably overrides the effects of low in-stream fertility.
