representative lakes in the Kawartha chain and data were collected on water 

 quality, temperature and oxygen content at these sites periodically during 

 the summer. 



Fish population studies were also started on Sturgeon and Cameron 

 Lakes by extensive trap netting. Fish collected from these operations were 

 tagged and returned to the water after relevant information pertaining to 

 length and age had been recorded. 



The unit also undertook the tagging and transfer of bass and maskinonge 

 from the Nogies Creek Fish Sanctuary to other waters in the Kawartha area. 

 This project, which has been in progress for a number of years, will be 

 managed by the Kawartha Lakes unit in the future. 



7. FISH POPULATION STUDIES 



Special investigations were carried out on Rainy Lake, Lake Nipigon, 

 Pointe au Baril area of Georgian Bay, North Channel at Blind River and 

 Lake St. Francis. In these studies, particular attention was given to the 

 distribution, abundance and growth of the existing fish populations. 



Regulations 



No major changes were made in the Ontario Fishery Regulations for 1963, 

 However, the following amendments are of general interest: 



(a) The brook trout season in southeastern Ontario and parts of north- 

 eastern Ontario was opened on March 1st. 



(b) Winter fishing for lake trout was permitted in the seven northerly town- 

 ships of Peterborough County. 



(c) A three-day non-resident angling licence was introduced. 



A new regulation was also established under The Game and Fish Act which 

 provides for licensing the sale of smallmouth bass, largemouth bass, brook trout, 

 brown trout, rainbow trout, Kamloops trout and Aurora trout for restocking 

 purposes and the sale of brook trout, brown trout and rainbow trout for human 

 consumption.
