Biological Projects 



The biological projects undertaken during the year, consisted of the following: 

 bass harvesting, sea lamprey control, Atlantic salmon experiments, controlled poisoning 

 of a lake containing undesirable species of fish to determine the possibility of establish- 

 ing desirable species, creel census studies, fish tagging and biological surveys of lakes 

 and streams. 



Bass Harvesting 



During the summer months, adult smallmouth bass and largemouth bass were 

 harvested from the following lakes and distributed to suitable waters: Barton, Bastedo, 

 Cat, Davern, Fox, Little Gull. Little Silver. O'Reilly and Shoepac. 



Sea Lamprey Control 



Operations for the control of sea lamprey were continued. A number of weirs 

 were set in selected streams flowing into the North Channel. Many other locations 

 are being studied to determine their suitability for lamprey control operations. 



Removal of Coarse Fish 



Xets were operated on the following waters for the removal of undesirable 

 species: Bark Lake. Emily Creek. Kamaniskeg Lake, Xonquon River. Scugog Lake. 

 Twenty-Minute Lake and Wolfe Lake. 



Atlantic Salmon Experiment 



Studies relating to the re-establishment of the Atlantic salmon in Lake Ontario 

 were continued in Duffin Creek at Pickering. 



Fish Poisoning 



In Silver Lake at Port Dover, the coarse fish were removed by poisoning, and 

 yellow pickerel fry were planted. This plan seemed to offer considerable prospect for 

 the production of fingerling pickerel. 



Creel Census Studies 



Creel census studies were conducted on a number of waters to determine the 

 proportion of hatchery-reared trout in the angler's catch. This project included waters 

 in the district of Thunder Bay and Algoma, and in the counties of Bruce. Grey, 

 Victoria, Peterborough and Haliburton. 



Fish Tagging 



Six hundred yellow pickerel were tagged at the outlets of the Moon, Shawanaga 

 and French rivers to determine the facts regarding the movements of this species and 

 its availability to the anglers and commercial fishermen. 



The program, initiated last year, of tagging smallmouth bass in Georgian 

 Bay. was continued and 250 additional smallmouth bass were tagged. 



Biological Surveys 



A long term project is being conducted on Long Point Bay. Lake Erie, to 

 determine the relationshop of commercial fishing to angling. 



Investigations of a biological nature 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 extensions of previous ones. The waters studied were 

 as follows:
