A breakdown of the cost analyis data for the total production of fish at the 

 Chatsworth station in 1965 is as follows:

The Normandale Trout Rearing Station was placed back into operation in 

 1965 following reconstruction of the ponds and the hatchery building. Land- 

 scaping, road building, and some minor modifications to the hatchery facilities are 

 the only remaining unfinished items required to complete the renovation. 



A progressive step was taken with the installation of a water heating unit in 

 the Normandale hatchery. Though experimental in nature, the unit was not only 

 used to increase the temperature of the water for egg incubation and thereby 

 accelerate the hatching of rainbow trout spawn but also tempered the wide range 

 in daily temperature fluctuations of the hatchery water supply. 



Production at the North Bay station was reduced this year in preparation for 

 its complete renovation. Though preliminary plans and surveys have been com- 

 pleted, construction is not expected to commence until 1966. 



The Thayer property, located adjacent to the Tarentorus station at Sault Ste. 

 Marie, has been set aside for future development as an experimental hatchery and 

 training centre for fisheries workers. This station will fill a gap in the Canadian 

 field of education. It will also provide a site and facilities for much needed 

 experimentation in fish culture. 



The total distribution of fish from provincial hatcheries for 1965 is outlined 

 in Table II. This year approximately 49,294,311 fish, including age classes varying 

 from eyed eggs to adults, and including ten species, were produced and planted in 

 Ontario waters. 



The distribution of hatchery reared fish, tabulated by species, for 1965 and 

 for the four previous years is recorded in Table III. 



The most significant change in the distribution this year was the production 

 of 2,579,324 kokanee, the freshwater form of the sockeye salmon. These egg 

 stocks were obtained from provincial and state agencies in British Columbia, 

 Montana, Washington and Colorado for incubation, culture and planting in Lakes 

 Huron and Ontario. It is hoped that this desirable fish will compete favourably 

 with the alewife which is currently present in very large numbers. The successful 

 introduction of kokanee is expected to quickly augment the commercial catch as 

 well as the anglers' creel in these waters. The kokanee also forms an important 

 link in the food chain between planktonic life and such desirable species as the 

 rainbow trout and splake.
