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 which almost all of the nets were lifted. The more exact data obtained in these two years form the basis for most of the material that will be presented, a!though some references will be made to the fishing operations of 1930.
