Biological Surveys 



A creel census was commenced in the Kawartha Lakes area and intensive 

 studies were conducted on the maskinonge in its natural environment. 



Studies were made on the establishment of sanctuaries for smallniouth bass 

 in the Georgian Bay region. 



By checking the commercial fishermen's chub nets in Georgian Ba\- and 

 Lake Huron a surve\' was made to ascertain to what extent these nets catch 

 Lake Trout. 



An investigation was conducted on East Lake, Prince Edward County, to 

 determine the effect of commercial hoop net fishing on the game fish. 



A creel census was undertaken in Grey County to determine the proportion 

 of hatchery-reared speckled trout in the angler's catch. 



A creel census programme was undertaken in the District of Thunder I3a\-. 



The experiment on Round Lake, Renfrew County to determine the effect of 

 removal of coarse fish on the game fish population was continued. The lake was 

 fished heavily during the summer and a large number of coarse fish removed. 



Operations for the control of the sea lamprey were continued. 



During the past few >ears, a pound net was set in the causeway leading to 

 Osier Marsh in Lake Scugog, Ontario County, to control carp and stud>' maskin- 

 onge and bass. 



During the summer, smallniouth bass adults were harvested from the 

 following waters: — Cook's Lake, Thunder Bay District; Fox Lake, Kenora 

 District; Little Gull Lake, Haliburton District; and Burnt Lake, Parry Sound 

 District. 



In addition to these small mouth bass harvesting operations, one project 

 was undertaken for the transfer of largemouth bass and maskinonge from Xogies 

 Creek Sanctuary, Peterborough County. 



Biological investigations were made on a number of lakes and streams with 

 a view to the establishment of a sound fish management plan. These were either 

 initial surveys or an extension of a previous one. The w^aters studied were as
