ANNUAL REPORT, 1943-44 25 



Work was continued on the study of insect population of streams as fish food 

 and the studies of the temperature and oxygen conditions in lakes as related to the 

 movements of fish. Experiments were continued on the rate of digestion of food 

 by fish to determine the amount of food used by fishes during a year as the basis for 

 measuring the productive capacity of game fish in the various Park lakes." 



The work of the laboratory has been reported, annually, in several publi- 

 cations. 



ACKNOWLEDGEMENTS 



In conclusion I desire to express general satisfaction with the services of res- 

 pective members of the Departmental staff, both at headquarters and in the field. 

 They were conscientious in the performance of their duties and courteous in their 

 contacts with the general public. 



The co-operation of the Ontario Federation of Anglers and Hunters, as well 

 as the local Fish and Game Protective Associations and the Northern Ontario Tour- 

 ist Trade Association has been provided at all times and has resulted in a better 

 degree of law observance in the interests of protecting the fish and game resources 

 of Ontario and has resulted in easing the burdens of administration. 



Assistance has been forthcoming from many other organizations and indi- 

 viduals too numerous to specify in detail, and particularly from Municipal Coun- 

 cils and Controlling Organizations in the Townships incorporated in the scheme 

 of Regulated Game Preserve Areas and which in large measure has been respon- 

 sible for the success which this scheme has presently attained. 



All of which is respectfully submitted. 



I am, Sir, 



Your obedient servant, 



D. J. TAYLOR, 



Deputy Minister of Game and Fisheries
