Maskiuouge Creek flowing from .Maskinonge Lake it) Little W'rniillion Lake; 

 Maskinonge Lake (Part); Little \'ermillion Lake (Part) located in the township 

 of Pickerel, District of Kenora. 



Moose Lake located in unorganized territory- west of the Township of 

 Smellie, District of Kenora. 



Biological Surveys 



The Game Fish Section expanded their work, especialh' in respect of bio- 

 logical surve\s. Surv'e>s were conducted on a great man\' lakes and streams 

 to obtain data basic to the fish management plan. This included four lakes in 

 Frontenac County, one in each of Lennox and Addington and Hastings Counties, 

 three in Xipissing District, fi\'e in Parr\- Sound District and several minor waters. 



A project was undertaken to assess the value of planting streams in Bruce 

 County with hatchery raised speckled trout. The trout were planted as yearlings 

 in parts of the S\denham River, Eugenia Hydro Pond and Williams Lake, and 

 were marked by removal of the adipose fin. A careful check on all of the fish 

 taken from these waters is being obtained b>- means of the creel census. The 

 experiment is being continued. 



An exjx'riment begun in 1945, was continued at Round Lake, Renfrew 

 County, to determine the eft'ect of removal of coarse fish in quantity, from a lake. 

 The lake was heavih- fished b>- means of trap and hoop nets, the coarse fish 

 removed and the game fish returned to the lake. This experiment is continuing. 



Creel census sur\-e\'s and assessment of waters was continued in Sibky 

 Provincial Park. 



Preliminar\- in\-estigations were begun to obtain information concerning 

 the life history and possible means of control of the Sea Lampre\-. Deterioration 

 of the lake trout fisher\- of the Great Lakes, particularly in Lake Huron and 

 Georgian Bay, is attributed to the abundance of this fish parasite. This most 

 important work was begun in the waters of Lake Huron adjacent to Bruce 

 Count}', and is cf)ntinuing. 



An extensi\-e siu'vex' of lakes in which Kamlocjps Irout ha\e been introduced 

 was undertaken. These waters included Lake Bernard and Poole Lake, Parr\- 

 Sound District, Echo Lake, Rill Lake, Clear Lake, Red Chalk Lake, Lake 

 Waseosa, Round Lake and Deep Lake, Muskoka District and Lake Timagami. 

 .\i|)issing District. .Assessment of fishing for this excellent game fish was made. 

 With the excejition of Lake Timagami, the Kamloops trout appears to have 

 become well established in ,ill of I he lakes noted and is proxiding fair to good 

 fishing. 



Tin- .\tlantic Salmon experinuMit, which was begun in 1944 in Duffin's 

 Crick, Ontario Count}-, was continued. The exinriment is being conducted 

 for two reasons. First, an effort is being made to establish the Atlantic .Salmon 

 in Lake Ontario and its tributary streams, where it was formerh- abundant, and 

 second, an effort is being made tf) seciu'e an appraisal of the efficienc\- of restock- 

 ing streams with hatcher\' raised lish. As this is a long term in\-estigation, it is 

 too earl\ to draw conclusions, though it ma>" be stated that some of the fish 

 that were planted in 1944 ha\-e been recaptured, and are showing .satisfactory 

 growth. (ieni'ralK' si)eaking. the results are encouraging.
