A perusal of the detailed Re\enue Statement published elsewhere in this 



report will reveal the fact that during 1927 the revenue derived from angling 



licenses was in excess of that obtained from the commercial fishermen in license 



fees and royalties, which was chiefly due to the substantially increased revenue 



secured under the issue of angling licenses. The following statement of revenues 



derived from the sale of angling licenses during the years 1924 to 1927 inclusive 



will be of interest.

Hatcheries 



As has been stated elsewhere, accompanying this report will be found 

 statistical tables showing in detail the quantities and varieties of fry and fingerling 

 deposited in the various waters of the Province from the Department's hatcheries 

 located at Mount Pleasant, Glenora, SaultSte. Marie, Normandale, Port Carling, 

 Port Arthur, Fort Frances, CoUingwood, Wiarton, Kenora, Sarnia, Southampton, 

 Kingsville and Belleville and for comparative purposes, the following figures 

 show a summary of total distribution for the past three years.

Biological Ixvestigatiox.s 



During the summer of 1927, biological surveys were carried out on two hun- 

 dred and thirty-three {233) lakes and streams in the province, and, to date of 

 writing, biological data ha\"e been accumulated from a total of three hundred 

 and twelve (312) waters. 



The purpose of these studies is to determine the species of fish best suited 

 to the waters and to make such recommendations for restocking as will assist 

 in using them to their best possible adx'antage. 



We estimate the numbers of fish to be planted, after coordinating the follow- 

 ing data: — 



(a) Biological, physical and chemical characters of the waters. 



(b) The size of fish planted. 



(c) Area of the water. 



(d) The extent of fishing. This is not an arbitrary estimate, but one based 

 on the recent findings of scientific investigators,
