The Channel Catfish was shown by Speaker (1948) in a sample of 1800 Iowa anglers to be the most important species of fish inhabiting the inland streams of Iowa. Therefore, any information concerning its life history and habits is important and of value in formulating a management policy for the species. To get information on the life history and habits of the channel catfish, tagging experiments were initiated in 1947. Tagging was carried on through 1949 and recoveries are continuing. The information sought by this investigation was: (1) to study the possibility of using marked fish for an inventory of stream populations of channel catfish, (2) to determine the extent of movements of catfish in Iowa's inland streams, and (3) to secure factual information relative to the rate of growth of catfish in what is presumed to be good catfish habitat. The purpose of this paper is to record the information gathered to date and to discuss the value of the methods employed as instruments for studying the channel catfish.
