These data describe the catch and biological data from 363 bottom-set gill-net lifts distributed throughout Lake Michigan (including main basin and Green Bay) between April and November in 1930?1932. Data collected from the R/V Fulmar were recorded in notebooks and are now archived at the U.S. Geological Survey's Great Lakes Science Center. Each lift included 1?7 gangs of linen gill nets. Each gang comprised 3?5 panels each having a length of 155 m, a height of 1.5 m, and a (stretch-)mesh size of either 60, 64, 67, 70, or 76 mm. The digitization of the Fulmar data notebooks was started in the late 1990s and finished in this study.
