 Undersized fish were separated on the basis of a lV^-pound limit]

Lakes Huron and Michigan, 1931-1932 



[The total-length intervals apply to fish with lengths up to but not including the upper limit. The average lengths of legal-sized and undersized fish 

 were based only on those individuals for which records of weight also were available (number of specimens in parentheses). Undersized fish were 

 separated on the basis of a lJj-pound limit, not on length] 



The situation with respect to the lake trout was somewhat different. The few 

 trout gilled in meshes smaller than 3 inches were all undersized (less than l T /2 pounds) 

 (table 41). The legal-sized trout started to gill noticeably in meshes of 3 to 3 7/16 

 inches. Only 24 percent of the gilled fish in these meshes were undersized, and the 

 average weight (1 pound, 11.8 ounces) of all gilled fish was well over the legal size 

 limit. The percentage of undersized gilled trout decreased to 11.4 in the 3V&- to 

 3 15/16-inch meshes, and no illegal-sized fish were gilled in larger meshes. An exam-
