GAME AND FISHERIES 



The recommendations for the waters in\-estigated during the current year 

 as regards species were as follows: Speckled trout, 66; lake trout, 24; brown 

 trout, 3; small-mouth black bass, 80: large-mouth black bass, 12; pickerel, 2; 

 pike, 2 ; maskinonge, 1 ; number of waters considered unsuitable for game fish, 46; 

 number of waters closed, 6. In some cases, two species of fish have been 

 suggested for the same waters and this accounts for the apparent discrepancy in 

 the total number of waters investigated.

Biological studies were continued on Lake Simcoe at con\enieni interxals 

 during the summer. A special study of the cause of carp mortality in the lake 

 was undertaken. In this regard the F'ish Culture Branch worked in cooperation 

 with the Department of Public Health Laboratories and some interesting results 

 have been obtained. I^xperimental work is still in progress. 



Bif)logical studies of the Thames watershed were commenced and plans are 

 being made to continue the work more intensively next year.
