Speolal Project a 



Seven major trap netting operations were undertaken by the Department in 

 1960» These included operations oonduoted on Lake Timagaml (iTorth Bay Distriot), 

 Kashagawigamog Lake (Lindsay District), Little Rideau Lake (Kemptville District), 

 Grass Lake (Lindsay District), Caxming Lake (Lindsay District), Shadow Lake (Lindsay 

 District) and Lac Seul ( Sioux Lookout District)* 



All of these projects with the exception of the operation on Lao Seul were 

 conducted primarily to obtain large samples of fish for examination (age and growth 

 studies) and for tagging or marking and release for subsequent popxilation studies. 

 The project on Lao Seul was xmdertaken to determine the effectiveness of deepwater 

 impounding gear for possible futxire use by licensed commercial fishermen operating 

 on Lao Seul* The nvimber of fish harvested during each of these operations is 

 recorded in Table 4« 

 2* Patricia Inventory Project 



This project was initiated in 1939 "^o obtain factual information on the 

 fisheries resource in the Patricia area of northern Ontario for use in the manag«nent 

 of the existing commercial and sport fisheries and for planning the future development 

 and utilization of the resotirce in the area* 



Diiring 1939 ojod. i960 comprehensive lake surveys and fish population stxidies 

 were undertaken on Deer Lake, North Caribou Lake, Big Trout Lake and Hawley Lakes, 

 and a preliminary stxidy was made on the speckled trout fishery in the Sutton Elver* 

 In i960 water samples were also obtedned from an additional 26 lakes in the Patricia 

 area for chemical analyses* Althcxigh all of these studies are still In progress 

 much valuable Infoxmatlon has already been obtained on the physical and chemical 

 qualities of the waters examined and on the characteristics of the respective fish 

 populations* For example, it is apparent from results obtained to date that the 

 lakes in the Patricia area of northern Ontario are relatively less productive than 

 compeurable western lakes located in the same latitude* It is also evident that the 

 growth rates for most speoies of fish inhabiting the lakes in northern Ontario are 

 considerably slower than in more southern lakes* Both of these factors are basic 

 considerations to management and, while it is recognized that more pertinent data 

 are required before properly detailed plans can be formulated, the information at
