make a distribution of doubk- that of tlie previous \ear. The plantings of this 

 species b\' age group is as follows: 



50,000 fry 

 84,730 tingcriings 

 2.760,780 yearlings 

 8,656 adults 



Broivn Trout 



The plantings of brown trout \earlings were good, with a total of 268,940 

 being distribtited. This was an increase of 20% over the previous year's distri- 

 bution. In addition, we had a surplus of fingerlings which we could not hold 

 for another \ear, and these made a distribution of 133.025. Taken together, 

 the figures for this distribution were excellent, considering the number of ponds 

 which we have available for the raising of brown trout. 



Rainboii' Trout 



(a) Steelhead. It is only in the larger rixers and lakes that rainbow trout 

 are normalK' found except in their immature stage. A river such as the Xotta- 

 wasaga is a good example in which rainbows remain throughout the >"ear. The\' 

 survive chiefly in the larger lakes such as Lake Simcoe and the Great Lakes. 

 Distribution this \'ear was mainh' confined to the larger rivers flowing into the 

 Georgian Ba\ . 



(b) Kamloops. This species was introduced to a number of carefulh" 

 selected lakes in Ontario, and the Kamloops in these lakes are showing excellent 

 results during the last few years. Up to now, the practice has been to distribute 

 this species in the yearling stage, but this year there was a distribution of 4,850 

 as adults, which was an excellent contribution to the culture of this species in 

 Ontario. 



Lake Trout 



For the last several \ears there has been a decline in the i)ro(luction in the 

 spawn collection of this species. Steps are now being taken by the Department 

 to ascertain the fact responsible for the decline, with a view to providing a 

 remedy. The distribution in 1946 shows a sharp drop over that recorded in 

 1945. As stated above, this is wholh- due to the fact that our hatcheries are 

 not getting the spawn in such large numbers as previously. The distribution 

 of 28,045 yearlings was a considerable decline over the previous year as the 

 hatcheries were not able to retain as many fingerlings from the previous \ear 

 as had been done formerK-. 



White fish 



I he s])awn collection of this species was considerablx down trom the j)revious 

 year. 'I'his gives the reason for the slight dt'cline in the plantings, as shown 

 in the tables. 



Herring 



In comparison with the last few >ears, the distribution of herring .was realK' 

 excellent. There was a total planting of 69,674,000. This large increase was 

 wholly due to a very good run of herring in the spawning season, together with a 

 week of good weather, when our sj)awn lakers can work at their best. 



Yelloii' Pickerel 



There was a ])lanting of 142,385,000 fr\ this \eai- which was a decline of 

 about 20% from the i)re\ious year. The drop in the distribution was accounted 

 for soleK" from the fact that the fish could not i)e captured in large enough 

 quantities during the spawning season. The chief spawn taking areas where
