Abstract

Saugers, Stizostedion canadense (Smith), were collected in the Mississippi River (Pool 19) in 1966 and 1967 as part of a study of fish ecology and food habits. The length-weight relationship was described as

Log W = -5.552 + 3.184 Log L

where W = weight in grams and L = total length in millimeters. In August, 1966, and June and July, 1967, condition did not increase with increase in length as expected from the slope of 3.184, but in the other seasons there was such an increase. The average growth was similar to that reported for other sections of the Mississippi River. Growth was more rapid than that from Lake of the Woods, but slower than in new impoundments. Little difference in abundance of 1963 to 1966 year classes was evident.
