department. These practices vary all the way from intensive management (based 

 on hatchery stock) in specific areas in the south to management based on regu- 

 lation only in certain parts of the far north. 



The tools of fisheries management are numerous, but those used most 

 frequently in Ontario are fisheries research, lake and stream surveys, creel census, 

 fish stocking, fish population studies, regulations and law enforcement. A good 

 deal of such work is included in the routine duties of field personnel and is 

 reported in annual reports of Forest Districts. A number of special projects were 

 also undertaken in 1965 and some of these are outlined under separate headings 

 in this report. 



Hatcheries 



Seventeen fish hatcheries were operated in Ontario in 1965. These are listed 

 below according to classification, geographic location and Forest District.

The production and planting of hatchery reared fish forms a major part of 

 the fisheries management program in Ontario. Each year extensive plantings are 

 made with brook trout, rainbow trout and lake trout and, to a lesser extent, with 

 maskinonge, largemouth and smallmouth bass, whitefish, walleye, and the hybrid 

 splake. This year, the department also imported some three million kokanee eyed 

 eggs for planting in the eyed egg and fingerling stage in Lake Huron and Lake 

 Ontario. 



Although the assessment of fish production is difficult to determine accurately, 

 mainly because of the many variables associated with the culture of different 

 species and with the quality and size of the fish produced, production is, never- 

 theless, generally measured by the weight of fish produced. Using this parameter 

 alone, the following cost analysis data is supplied for the production at the 

 Chatsworth Trout Rearing Station following the completion of the renovation of 

 this station in 1963.
