PREFACE 



The quotations 011 the opposite page state briefly the 

 relation of fish to the use of non-agricultural, forest lands 

 and waters, as expressed by representative foresters, and this 

 clearly outlines the policy of this College on such matters. 



In addition to timber, forest lands and waters may be 

 used to produce fish, game and other plant and animal crops, 

 for which the region is suited, and in addition they may be 

 used for recreation. The diversified use of such forests is a 

 natural development which accompanies intelligent use of 

 natural resources. The proper management of waters is a 

 problem similar to that of the proper management of a farm, 

 of a business, or the care of forest trees, and each must be 

 based upon a detailed knowledge of the subject. The public 

 has not yet taken up very seriously the relation of fish pro- 

 duction to food, to recreation, and to the general economic 

 welfare of the community. There are conflicting interests 

 here which can only be justly disposed of, in part, after 

 careful, impartial investigation. It is to the solution of such 

 State problems that the College is devoting its energies. 



The present publication by Frank C. Baker, Investigator 

 in Forest Zoology of the College of Forestry, who since the 

 completion of these studies has become Curator of the Nat- 

 ural History Museum of the University of Illinois, Urbana, 

 Illinois, has here summarized two detailed studies which he 

 made on the fish food in Oneida Lake during the years of 

 1915, 1916 and 1917. His investigations show the kind of 

 food eaten by fish, particularly the molluscan or shellfish 

 food, and the conditions and relative abundance of this food 

 in certain parts of the lake. Plants are shown to have much 

 influence upon the fish food, and the depth of water has also 

 a great influence. In general, the amount of fish food 

 declines with increasing depth of water, and sand bottom
