Surface currents of Lake Michigan, 1931 and 1932
Seven hundred fourty-five bottles containing post cards for recording of information were released at stations in Lake Michigan; 283 were released June 17 to August 17, 1931, south of a line from Frankfort, Michigan, to Algoma, Wisconsin, and 462 during May 9 to August 25, 1932, both south and north of that line. One hundred eighty-six bottles or 65.7 percent of those released in 1931, 331 bottle

The use of alkalinity and conductivity measurements to estimate concentrations of 3-trifluormethyl-4-nitrophenol required for treating lamprey streams
A method has been devised to estimate the minimum concentration of TFM that will kill sea lampreys and the maximum that will not kill fish. It is based on the relation of these concentrations to the alkalinity and the conductivity of various waters. Pretreatment bioassays will continue to be required for precise determination of treatment concentrations, but the estimates made possible by the me

A study of the food habits of some Lake Erie fish
A study of the food habits by means of stomach analyses of eight species of Lake Erie fishes was begun June 16, 1958. The species studied were smelt, yellow perch, troutperch, spottail shiner, sheepshead, yellow walleye (hereafter termed walleye), gizzard shad, and alewife. In a similar manner, stomach analyses were made of the white bass and channel catfish. Both projects were parts of a coope

Limnological survey of Lake Erie 1959 and 1960
Federal, provincial, state, and university organizations participated in cooperative limnological surveys of Lake Erie in September 1959 and August 1960 to determine the extent and severity of the low dissolved-oxygen content of the hypolimnetic waters. Observations were restricted to the central basin in 1959, but were lake-wide in 1960. Approximately 70 percent of the bottom waters of the cent
