The Great Lakes fisheries: A review of the report of the International Board of Inquiry for the Great Lakes Fisheries
In August, 1942, the International Board of Inquiry for the Great Lakes Fisheries submitted its report to the governments of the United States and States and Canada. The report, which culminated a two-year investigation, recommended a common or joint agency of control for the fisheries through an international treaty.

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

Growth of the rock bass, Ambloplites rupestris (Rafinesque), in five lakes of northeastern Wisconsin
The forms of the growth curves of rock bass from four lakes in northeastern Wisconsin with medium-hard to hard water bore a general resemblance to each other, but differed sharply from the curve for rock bass from a lake with extremely soft water. With the exception of a slight increase in growth in the third year of life the annual increments of length of the rock bass of Nebish Lake (4.0 p.p.m.

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

Age and growth of the rock bass, Ambloplites rupestris (Rafinesque), in Nebish Lake, Wisconsin
The present study of the age and growth of the Nebish Lake rock bass is another in a series of papers that have been based wholly or in part on materials collected in the course of investigations on the fishes of the lakes of the northeastern highlands, Wisconsin, conducted cooperatively by the Wisconsin Geological and Natural History Survey and the United States Bureau of Fisheries over the perio

Bathymetric distribution of fish in lakes of the northeastern highlands, Wisconsin
The present study of the bathymetric distribution of fish in the lakes of northeastern Wisconsin has been based on records of the catches of gill nets fished during the summers of 1930, 1931 and 1932. During the first of the three summers, soundings were made only of the general area in which each gang of nets was fished. In 1931 and 1932, however, individual records were made of the depths from w
