ANNUAL REPORT, 1930 



39 



hatcheries located in the Province under the control of the Dominion Government 

 and used exclusively for the propagation of commercial fish were taken over. 

 Since then a number of these hatcheries have been used for the propagation of 

 game fish, and in this connection it should be noted that Provincial hatcheries 

 under Provincial jurisdiction were the first to go into the propagation of game 

 fish extensively, that being their original objective. The work in this connection 

 was limited to the culture of game-fish fry and early fingerlings until the establish- 

 ment and development of the Normandale trout ponds opened the way for the 

 culture of large trout fingerlings in raceways suitable for the purpose. 



At present the Department's holdings include sixteen hatcheries, five trout- 

 rearing stations, and two large bass ponds. These ponds, as well as the series 

 at the Mount Pleasant hatchery, are used for the propagation of small-mouthed 

 black bass. 



A section of Codrington Trout-rearing Station. 



The construction of four trout-rearing stations, in addition to the Normandale 

 trout ponds, was commenced during the year; and in 1930 three of these were 

 used for the culture of trout to large fingerlings. These rearing stations are 

 located at (1) the headwaters of Coldwater creek, near Sault Ste. Marie, district 

 of Algoma; (2) deep-seated springs, Petawawa township, near Pembroke, 

 Renfrew county; (3) headwater springs supplying Marsh creek, near Codrington, 

 Northumberland county; (4) headwater springs supplying Gibson's creek, 

 Provincial Government Reforestry Farm, Charlotteville township, Norfolk 

 county. 



In addition a large trout-rearing station is now under construction at the 

 headwaters of Spring creek near Dorion, Thunder Bay district. 



The greatest care was exercised in making each site an individual subject of 

 study from all angles. All of the sites chosen are accessible, so that speedy 

 transportation by truck and rail may be effected.
