Abstract

Although 117 fantail darters (Etheostoma flabellare) were collected from Bluff Creek, Boone County, Iowa, during summer 1962 and winter 1962-63, only 1 was found in the Des Moines River. Slenderhead darters occupy the similar riffle areas in the river. Female fantail darters were 18.7, 34.8, and 42.4 mm at the first through the third annuli, respectively, and male darters were 18.5, 36.7, 59.0, and 62.0 mm at the first through the fourth annuli, respectively. No females were found that had formed a fourth annulus. Average coefficient of condition for 104 fantail darters was 1.749. Length-weight relationships for males and females were statistically the same. Food of the fantail darter was 93% insects. The peak of the spawning period is probably in May.
