Abstract
Weekly minnow collections were made from August 13 to November 26, 1960, at five stations in Grimes Creek. Six major species were identified, counted and measured. The upper region of the creek was abandoned by the minnow population within a few days after pollution from a canning factory at Grimes, Iowa entered the stream. Late spawning species of minnows were unable to spawn successfully, which suggested one mechanism for selective evolution of minnow populations.
