DEPARTMENT OF GAME AND FISHERIES No. 9 (1944) 



Speckled trout are cultured at fourteen stations, rainbow trout at two, brown 

 trout at six, Kamloops trout at two, lake trout at nine, small-mouthed black bass at 

 seven, large-mouthed black bass at one, maskinonge at one, perch at one, blue 

 pickerel at one, yellow pickerel at ten, white-fish at ten, herring at three and min- 

 nows at four. X 



There are facilities at three stations for retaining a selected stock of adult 

 speckled trout for breeding purposes. A breeding stock of brown, rainbow and 

 Kamloops trout are provided for at one station. 



Practically all the speckled trout, brown trout and Kamloops trout distri- 

 J)uted to suitable and publicly fished waters are either yearlings or older fish. 



Black bass, maskinonge, rainbow trout and lake trout, are, generally speak- 

 ing, distributed in the fry or fingerling stages. Culture of lake trout to the yearling 

 stage has been developed, successfuly, at certain stations, and when additional pond 

 space is available, expansion of the culture of lake trout in this direction may be 

 undertaken. 



White fish, herring, perch, blue pickerel and yellow pickerel are distributed 

 in the fry stage. 



THE CULTURE AND DISTRIBUTION OF FISH 

 Speckled Trout: 



Approximately 3,084,000 speckled trout yearlings and 10,300 adults were 

 planted in suitable waters during the year. The distribution of yearlings was ap- 

 proximately 6 per cent greater than that of the preceding year. 



Brown Trout: 



The Department has been careful to avoid planting brown trout in streams 

 which still continue to support native speckled trout satisfactorily. Distribution of 

 browns is confined to those portions of streams of southern Ontario where there is 

 little if any likelihood of re-establishing native trout on a practical basis and where 

 speckled trout fishing is unimportant with the possible exception that in some cases 

 small feeder creeks may still continue to support a limited number of speckled trout. 



Some good results have followed the introduction of browns, but it is neces- 

 sary to obtain more information on the success of many individual plantings before 

 definite conclusions may be drawn. 



A total of 314,000 browns were planted, of which yearlings numbered ap- 

 proximately 96 per cent. 



Rainbow Trout: 



(a) Steelhead Trout: 



The distribution of rainbow trout fingerlings was 34% lower and yearlings 

 20% greater than that of the preceding year. 



(b) Kamloops Trout: 



The culture of this variety of rainbow trout was disappointing. The egg 

 collection from the breeding fish in the Normandale ponds has decreased. Whether 

 conditions of the environment, or methods of spawning are responsible for evident 

 sterility is problematical. A small supply of eggs was obtained from Kamloops B.C., 

 and the product of these is being cultured at Chatsworth Trout Rearing Station to 

 determine whether water supply and other conditions are controlling factors in 

 successful culture.
