1952 o Movements of yellow perch marked in southern Green Bay, 

 Lake Michigan., 1950„ Trans. Am. Fish. SoCo., Vol, 8l 

 (19^1), PPo 150-161. 



Analysis of data on recoveries in the commercial fishery 

 of 108 of U5I72 spawning yellow perch marked in southern Green 

 Bay in May 19^0 by strap "iags attached to the operculiim. Re- 

 coveries indicated progx-essive northward movement following 

 spawning. Fish recapt\ired outside the marking area averaged 

 significantly longer than those recaptured locally. Rise of 

 percentage return with increase in size suggested greater 

 ability of larger fish to survive tagging or to retain tags. 

 Marking by fin- clipping proved unproductive.

195lc An aquarium experiment on the American eel as a predator 

 on larval lampreys. Gopeia, 195l<, No. 2j, pp. 173-17ij.. 



A controlled experiment which proved that eels located 

 and destroyed larval lampreys in the bottom mud of an aquarium. 

 Importation of eels is suggested as a possible method of biologi- 

 cal control of the sea lamprey in the upper Great Lakes.

19iiO. Tagging experiments with lake trout, whitefish, and other 



species of fish from Lake Michigan, Trans. Am. Fish. Soc, 

 Vol. 69 (1939), pp. 63-8i;. 



Analysis of data on recoveries of 388 or 13. U percent of 

 2,902 fish (nearly half of them lake trout) tagged at Port Wash- 

 ington, Wisconsin, to establish patterns of movement of lake trout, 

 whitefish, lake herring, yellow perch, rainbow trout, sturgeon, and 

 other species. Recaptures of lake trout were at first local but 

 within 3 years were fairly well scattered throughout the lake. 

 Movements of other fishes varied from species to species. Data are 

 included on the growth of tagged lake trout, rainbow trout, whitefish, 

 and sturgeon.
