26 DEPARTMENT OF GAME AND FISHERIES No. 9 (194B) 



Planting of browns in suitable streams continues to yield fruitful results. 

 During the year, the Department received many reports of excellent catches from 

 waters which were previously barren of speckled trout, due largely to temperatures 

 unsuitable for them. 



Approximately 331,000 yearlings were planted this year, an increase of 90 

 per cent over the previous year's distribution. 



Rainbow Trout: 



(a) Steelhead: 



It has long been recognized that steelhead rainbow have a tendency to 

 migrate from streams in which they have been planted to larger waters such as the 

 Great Lakes during their second year or when they are about a foot in length. On 

 reaching sexual maturity, they ascend streams in spring and leave again after the 

 completion of spawning. Hence they are available to anglers for only a short time, 

 and consequently comparatively few are found in the fisherman's creel. 



It is only in the larger rivers and lakes that rainbow trout are normally 

 found, except during their immature stages. The St. Mary's, the Pine and certain 

 of the larger parts of the Nottawasaga are examples of rivers in which rainbows 

 remain throughout the year. They have survived chiefly in larger lakes, Superior, 

 Georgian Bay and Lake Simcoe, which they inhabit for the most part, as adults. 



Distribution was confined with few exceptions to the larger tumultuous 

 rivers flowing into Georgian Bay and Lake Superior, and larger rivers and lakes 

 of Southern Ontario where successful planting has been indicated. 



Approximately 32,200 flngerlings , and 4,000 yearlings were planted during 

 the year. 



(b) Kamloops Trout: 



The monthly bulletin of the Department, February, 1946, vol. 1, No. 4, con- 

 tains a detailed account of the life history, culture, and planting of Kamloops trout 

 in provincial waters. As mentioned in the Annual Report 1943-44, many of our 

 domesticated adult stock of Kamloops trout have not spawned satisfactorily with- 

 in recent years. Consequently, until eggs can be secured from the stock that is being 

 reared at Chatsworth Trout Rearing Station, the distribution of this species will be 

 limited. Notwithstanding this difficulty, a distribution of 7,200 yearlings was car- 

 ried out this year; this is a 44 per cent increase over plantings of the preceding year. 



Lake Trout: 



The collection of lake trout eggs in the fall of 1943 was 20 per cent lower 

 than that of the fall of 1942. This was reflected in the distribution in 1944 which 

 was 21 per cent lower than that of 1943. In addition to this distribution, 44,000 year- 

 ling lake trout were planted. 



Steps are being taken by the Department to ascertain the factors respon- 

 sible for the decline, with a view to providing a remedy. 



Atlantic Salmon: 



"Nearly 30,000 salmon of Miramichi stock obtained from the Dominion De- 

 partment of Fisheries, hatched at Glenora, and fed at the Waring Creek Rearing 

 Station for about 34 days, were planted on June 20, 21 and 22, 1944, in Duffin Creek 

 above Pickering by the Ontario Department of Game and Fisheries with the co-
