returns to date suggest that a large proportion of the whlteflsh stooks are taken 

 annually* Further study is aimed at determining if adjustments of fishing 

 pressure will allow increased production* 



Lake trout are rarely taken in Lake Ontario where they were once 

 .abundant* In an attempt to re-establish lake trout, plantings of marked fish 

 have been made by both the Province of Ontario and the State of New Tork* An 

 evaluation of these plantings forms part of the Lake Ontario program* 



Algonquin Pcurk 



The present program in Algoncjuin Park, which is attempting to find ways 

 of maintaining and improving the sports fishing, follows two main lines* First, 

 it is attempting to adjust fishing pressure by one means or another to a level 

 that will give the most efficient use of the game fish population* Second, it 

 Is attempting to discover what improvements to the environment will give increased 

 production* Some promising techniques, such as lake closure, fertillBation, re* 

 stocking, and the construction of artificial spawning areas have not been entirely 

 effective* Certain refinements may make them more effective* The creel oenstM 

 and studies of the habits and requirements of the game fish of the area contiooe 

 to suggest where weaknesses in these techniques lie* 



Parry Sound District 



In 195^ research personnel joined the field staff of the Parry Sound 

 district in a study aimed at the improved management of the pickerel sport 

 fishery in Three Mile Lake, Huskoka District* In an effort to improve growth 

 and better utilisation of the stock, transfers of fish were made from Three Ulle 

 to other lakes, and the minimum legal length for pickerel suspended* A tagging 

 program and creel census were initiated in order to follow any changes that might 

 occur in the fishery as a result of this action*
