(Tweed District), Christie Lake (Kemptville District), Dalrymple Lake (Lind- 

 say District), and Little Lake (Lake Simcoe District). Fishing operations were 

 also carried out to collect fish for the Mount Pleasant Public Fishing Area, 

 the Canadian National Exhibition and the Canadian National Sportsmen's 

 Show. Nets were also operated for the collection of lake trout eggs in Mishi- 

 bishu Lake, Lake Simcoe and Lake Manitou and for the collection of 

 whitefish eggs on Lake Manitou. 



The Port Arthur section of the netting staff was involved in two major 

 projects, i.e. Lake Nipigon (Geraldton District) and Rainy Lake (Fort Frances 

 District) during 1963. In addition, they participated in a number of lake 

 surveys conducted on Baril Lake, Greenwich Lake, Rose Lake, Whitefish 

 Lake, Marks Lake and Sigh Lake in the Port Arthur District, and on White 

 Otter Lake in the Sioux Lookout District. 



2. PATRICIA INVENTORY 



The Patricia Fisheries Inventory Project was initiated in 1959. The 



purpose of the project was to survey the important waters, examine the 



respective fish populations in detail, and to plan and institute appropriate 



management of the fisheries in the respective waters. To achieve this objective, 



a relatively intensive study was planned for each of the larger lakes and/or 



for at least one lake on each of the major watersheds in the area. 



This fact finding program has progressed steadily since its inception in 1959. 

 The following waters were examined during the summer of 1963: 

 Big Trout Lake 

 Sakwaso-Nikip group of lakes 

 Lake St. Joseph 

 Winisk Lake 



Sachigo Lake and the Sutton River 

 In addition to these major surveys, resource management officers con- 

 ducted eleven short term or preliminary surveys on minor lakes. As a result of 

 these surveys, commercial fising licences were issued on five of the 1 1 lakes 

 and fishing operations were carried on during 1963. 



3. OUANANICHE (ATLANTIC SALMON) PROJECT 



Although this fine sporting fish has been introduced to several waters in 

 Ontario in past years, Trout Lake near North Bay is the only lake in which 

 the species is known to be established. 



A project to study the life history and ecology of the ouananiche in 

 Trout Lake was commenced in 1962 and continued in 1963. Field studies 

 are being directed towards the investigation of the natural spawning activity 

 and the assessment of spawning success in Four Mile Creek, a spring fed 

 tributary. Observations have also been made on the spawning run of adults 

 and trap nets have been installed for the capture of young salmon on their 

 downstream migration. In addition, a number of plantings of hatchery reared 

 ouananiche (origin Trout Lake) have been released in tributory waters. This 

 year two plantings, including 1,250 fry and 4,520 marked yearlings, were 

 made in North River and Four Mile Creek. Few detailed results are available 

 at this time. However, adult salmon have been sighted in Four Mile Creek, 

 presumably on their spawning run, and a few young salmon have been taken 

 on their downstream migration, but further data are required before a proper 

 analysis or assessment can be made.
