Abstract Longnose dace taken mainly during night hours over gravel‐rock substrates in a surge zone of east‐central Lake Michigan provided seasonal data on distribution, age, growth, maturity, fecundity, and food habits. Dominated by age‐classes II and III, longnose dace entered surge‐zone waters in mid‐May for spawning and remained in small numbers through November. Peak spawning occurred during late June and early July. Egg production ranged from 870 to 9,953 eggs per female. Age 0 fish were taken in early August and reached a mean length of 42 mm by late October. Only a few yearlings (age I) spawned the following year; all fish were mature by age II. Major foods of adult fish were from terrestrial sources.
