 gation of the marked increase in abundance of walleyes 

 in Green Bay^ The Fisherman^, Vol„ I8, No, 3s ppo 5-6o 



Popular discussion pointing out: that the abnormally high 

 abundance could be traced almost entirely to a single year class 

 (19[|.3)| that a return to a much lower level could be considered 

 inevitable; and that restrictive regulations, intended to perpe- 

 tuate the abnormal abundance would prove disappointing and would 

 place ^lnneGessary handicaps on the fishing industry.
