21. Importance of Bottom Organisms as Trout Food With Special Emphasis on the 

 Fresh Water Midge (Tendipedidae, Diptera) 



Square foot bottom samples and 25 sublegal trout were removed from three 

 streams in Michigan during a 13 -month period. The bottom samples are sorted, 

 the volumes of the fauna determined, then statistically treated. 



The objectives are: (1) To determine the importance of the midge fauna in 

 the diet of trout, (2) the importance of other aquatic insects, and (3) the rela- 

 tionship of No's. 1 and 2 with respect to the seasonal distribution of the square 

 foot bottom samples.
