Abstract

Age, growth, and food habit studies were done on 61 johnny darters, Etheostoma nigrum, 25 slenderhead darters, Percina phoxocephala, and 18 blacksided darters, P. maculata, taken from the Des Moines River, Boone County, Iowa, during the summer 1962. The growth rate of blacksided darter is faster than either of the other two species. Coefficients of condition, length-weight relationships, and body-scale relationships are similar for the three species. The food of all species is over 90% insect. Leeches and tapeworms parasitized the darters.
