The results from creel census returns also supplement growth and 

 population studies. Information provided voluntarily by Interested sportsmen 

 has provided very worthwhile reOords on fisheries, particularly in the 

 Kenora, Sault Ste. Marie and North Bay Districts where rather extensive 

 studies have been initiated. 

 Reclamation and Restoration Program 



Certain lakes and streams which have been subject to mismanagement 

 either by the introduction of an undesirable fish species, thoughtlessly and 

 illegally, or by improper or inadequate harvest, resulting in an unbalanced 

 and/or stunted fish population, have been treated with commercial toxicants 

 to eliminate the existing fish population. Such treatment is followed by 

 the introduction of one or more desirable fish species. 



In general the program is limited to small laJces that do not exceed 

 25 acres, because of the difficulty of performing a controlled treatment on 

 larger water areas and the cost of the toxicant. 



Most of this work has taken place in the Lake Erie, Huron and Swastik 

 Districts, In nearly all instances the projects have been sponsored by local 

 fish and game groups. 

 Construction of Farm Ponds 



In southern Ontario, particularly, landowners are taking more and mor 

 interest in the development of farm ponds. The establishment of such reservoirs 

 ranging from 1/2 acre or less to 15 acres, provides valuable water storage, 

 and at the same time permits the rearing of a fish population for food, 

 recreational and, in some instances, commercial purposes. 



Although the construction of farm ponds in Ontario is developed almos 

 wholly by private enterprise. Department Biologists may assist wherever posslb] 

 as consultants on the construction of the ponds, and the establishment of a ^1 

 desirable fish population. When the desired fish species, usually speckled 

 trout, smallmouth or largemouth bass or bluegills cannot be procured from 

 private hatcheries the Department may assist by providing stock for purchase 

 if the stock is available after the requirements of public waters are fulflllec 



Most of the farm pond construction is currently being developed in 

 the Lake Simoce, Erie and Huron Districts. A growing interest in the venture 

 is also noted in the Rideau, Quinte, Parry Sound and North Bay Districts.
