FISHERY BULLETIN OF THE FISH AND WILDLIFE SERVICE 



indicates that some of the smallest individuals escaped. The average weight of the 

 legal-sized, gilled whitefish, however, did not increase progressively with an increase 

 in mesh size (the average length showed a slight increase), thus suggesting that virtu- 

 ally no whitefish of 2 pounds or larger passed through any of the meshes for which 

 there were adequate data.

Lakes Huron and Michigan, 1931-1982

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 2-pound limit, not on length]
