Diets of syntopic finescale dace, Phoxinus neogaeus, and northern redbelly dace, Phoxinus eos: a reflection of trophic morphology

We examined relative abundance, distribution, and gut contents of Phoxinus eos and P. neogaeus in a small northern Michigan bog lake. P. eos were usually 5–100 x more abundant than P. neogaeus, but both species were more abundant near the lake margin than offshore. Both species fed primarily on algae and invertebrates associated with the bog mat, but… (More)
