MICHIGAN REPORT NO. 533 A THIRD EXAMINATION OF MICHIGAN INLAND LAKES IN WHICH PLANTINGS OF GREAT LAKES SHINERS (NOTROPIS ATHERINOIDES) HAVE BEEN MADE During 1933, 1934, and 1935 the Michigan Department of Conservation introduced into various inland lakes of Michigan numbers of the Great Lakes Shiners (Notropis atherinoides atherinoides). A summary of the plantings which have been made in lakes which were later examined is given in Table 1. From August 29 to September 1 Mr. W. F. Carbine assisted by Edwin L. Cooper examined these nine lakes in an effort to determine whether or not the species had become established in sufficient numbers to make it important in the ecological set up on these lakes. Data pertaining to these examinations are given in Table 2. To date five examinations of these lakes have been made. Four of these were made by Mr. Gerald P. Cooper during 1934 and 1935. His findings are summarized in Table 3; (also see Institute Reports Nos. 264 and 323a). From the data obtained by Mr. Cooper it seems safe to say that natural reproduction has occurred in some of these lakes. The only additional data obtained by Mr. Carbine comes from one specimen taken in Crystal Lake in Oceana County on August 30, 1938. As there appear to be five annuli present on the scales of this fish, it may represent one of the original planting.

Page  2 -2 -This species of fish is a popular bait fish, and is sold quite generally in the region by bait dealers, so there has probably been incidental introduction into these lakes by fishermen. After three years these seinings should indicate whether or not the shiner is able to maintain itself in inland lakes. However, it must be pointed out here that to date the examinations which have been made were rather cursory, and because of the fish's schooling habit, it would be quite possible for the persons who were conducting the examination to miss the species entirely. Mr. Carbine feels that in order for the examinations to have any significant value at least a day at each lake should be spent in trying to collect them. He makes the suggestion that more thorough examination of these lakes be made this year. INSTITUTE FOR FISHERIES RESEARCH By Walter R. Crowe Fisheries Research Technician
