Relationship between plantings of fry and production of whitefish in Lake Erie
An attempt was made to substantiate the repeated assertions of the commercial fishermen on the Great Lakes and of others that there was a direct causal relationship between the plantings of whitefish fry and subsequent catch. The records of whitefish fry plantings in Lake Erie during the years, 1920–1937, were correlated with those of catch during the period, 1923–1940. No causal relationship coul

Age, growth, and production of the yellow perch, Perca flavescens (Mitchill), of Saginaw Bay
Ages were determined and individual growth histories computed from the examination and measurement of scales from 820 yellow perch collected in 1929 and 1930. Calculated lengths greater than 101 millimeters were computed on the assumption (supported by empirical data) that the ratio of body length to scale length is constant. Lengths below 101 millimeters were determined with the aid of an empiric
