1931. These fingerlings measured from 3 to 8 inches in length. During subsequent 

 years this number has not been approximated and, in fact, none of the States 

 culturing maskinonge in their hatcheries has since produced in excess of 2,000 

 maskinonge fingerlings by the pond cultural method. 



As a result of a study of this problem in Ontario, it was found that the factors 

 chiefly responsible for unsuccessful attempts to rear maskinonge in appreciable 

 numbers were twofold. 



1. The difficulty of supplying adequate and suitable food requisites. 



2. The problem of cannibalism. 



These two factors must be surmounted and the only way in which this can be done 

 is to study the problem in a practical manner, by experimental rearing in ponds of 

 the fish themselves and of the forms of life which they require for their sustenance. 



SANCTUARIES 



In view of the limitations of bass and maskinonge culture and to fulfill the re- 

 quirements of these important species in our waters, their protection in a natural 

 state is essential. 



From the fisheries standpoint the sanctuary principle consists in having an area 

 completely removed from public or private use. In view of an ever-increasing 

 tourist trade, fishing for the species under discussion will become more and more 

 intensive and, considering the inaccessibility, ease and speed with which our waters 

 may be fished, it becomes increasingly evident that sanctuaries are necessary. Fish 

 sanctuaries fulfill three important purposes: 



1. They give the fish a chance to grow. Fish do not grow by magic and if we 

 want larger and better fish, we must give them a chance to grow and repro- 

 duce normally. 



2. Sanctuaries act as bases of supply for replenishing outer or adjacent fishing 

 waters. 



3. They may be very useful for stock and supply. 



It is only within comparatively recent years that this fundamental factor in 

 fisheries' management has been pursued with vigor and during the past few 

 years the Department has made marked progress along these lines. 



With these facts and also the conservational principles already discussed in 

 mind, the Department's objective is to bring all feasible measures to bear on the 

 problem of maskinonge and bass maintenance and protection, in order to shorten 

 any gap between supply and demand. 



During the past spring and summer a biological survey of the Kawartha Lakes 

 was conducted in order to dertemine the most suitable water areas adjacent to 

 lakes and streams to set aside as sanctuaries for bass and maskinonge. As a resiiU. 

 the following areas were established on this basis: 



(a) In Peterborough County: 



Black Duck Lake (Deer Bay), located in the Township of Harvey; Chemong 

 Lake, that portion located in the Township of Smith, Concession 4, Lots 1-3, 

 inclusive; 



Duck Ponds (Stony Lake) located immediately east of Gilchrist Bay, between 

 McCracken's Landing and Crow Landing, located in the Township of Dummer; 



Katchiwano Lake, that portion located in the vicinity of Lakefield, south of a 

 line drawn from Haig's Point to Webster's Farm, in the Township of Smith;
