ANNUAL REPORT, 1937-38 19 



The successful maintenance and increased usefulness of these interests are 

 being developed in a variety of ways and the re-stocking of lakes and streams in a 

 practical manner is of outstanding importance in this connection. To this end a 

 vigorous fish cultural programme is being pursued with satisfactory results. 



HATCHERIES AND REARING STATIONS 



During the year the Department operated twenty-four fish cultural stations. 

 The actual number of hatcheries operated was twenty; trout rearing stations, eleven; 

 bass rearing stations, four, and additional facilities were provided as outlined in 

 the following paragraphs. 



At the Fort Frances hatchery facilities were provided for carrying lake trout 

 to the fry and early fingerling stages. 



An excellent site for bass rearing ponds was located at the outlet of Lake 

 Manitou, Manitoulin Island, in the vicinity of Sandfield. One pond was completed 

 before the end of the year and was used, successfully, for wintering trout fingerlings 

 to the yearling stage. 



A second bass rearing pond, approximately one acre in area, was provided 

 at the White Lake Station, Frontenac County. Speckled trout were wintered in this 

 new pond very successfully. 



An additional trout pond was added to the series of three on the property of 

 the Ontario Government Reforestry Station at Midhurst, and acquired for use by the 

 Department. 



The water supply from Waring's Creek, located one and one-half miles west 

 of Picton, was used for rearing trout fingerlings. This station was provided with 

 outside rearing troughs of portable construction. 



SPECKLED TROUT: 



The Department continued the policy of rearing large numbers of trout 

 to yearling and older stages for distribution to suitable public waters. The results 

 of this plan have been successful. 



The following comparative distribution figures indicate the progress that 

 is being made: 



1936 1937 



Yearlings 557,270 1,167,073 



Adults 6,081 16,150 



In addition, 384,725 fingerling trout were planted, slightly more than one-third 

 the number planted the previous year. The entire abandonment of the distribution 

 of trout fry and fingerlings is contemplated, with the exception of any surplus which 

 cannot be accommodated in our rearing stations. 



BROWN TROUT: 



Excellent progress was made in regard to rearing brown trout to the yearling 

 stage. During the year 97,484 yearling and older brown trout were distributed as 

 compared with 7,290 during a similar period in the preceding year. 



Encouraging reports of successful angling for this species have been received and 

 intensive re-stocking of suitable streams in southern Ontario is being pursued on 

 the basis set forth in the two preceding reports. 



RAINBOW TROUT: 



(a) Steelhead Trout — 



The waters chosen for the planting of steelhead trout were such as to fulfil 

 the natural requirements of this species; the number of steelhead rainbows planted 

 was somewhat less than the number planted in 1936, but the number of Kamloops 

 trout (an allied species) distributed made up for this deficit.
