Over thirty-five million walleye eggs collected at the Talbot River (Lake 

 Simcoe) were incubated at Deer Lake hatchery, White Lake hatchery, and Glenora 

 Fisheries Station. Of the walleye incubated at Glenora, 2,731,968 were shipped 

 in eyed egg stage to Colorado and Montana in exchange for kokanee eggs received. 



The pond culture of walleye at White Lake hatchery was again carried out in 

 1965. In addition to the exploratory pond culture program, tests were made to 

 determine whether walleye fingerlings could be raised on artificial food. Finger- 

 lings two inches in length were held in troughs and presented with various diets. 

 Considerable losses of fry were experienced during these initial attempts at 

 artificial feeding. However, some limited success was experienced and plans are 

 being made to continue with the study in 1966. 



The Manitoba government again provided Ontario with 200,000 lake trout 

 eyed eggs in exchange for 100,000 brook trout eyed eggs and 50,000 maskinonge 

 fry supplied by Dorion and Deer Lake hatcheries respectively. 



Listed below are other agencies which were provided with hatchery stock for 

 research purposes.

The Dorion and Tarentorus Trout Rearing Stations again produced yearling 

 lake trout which were marked and planted into Lake Superior as part of an 

 international rehabilitation program. The location of plantings and the approximate 

 number of fish released at site was as follows:

A special project on assessing the use of plastic bags in the transfer of fish 

 was carried out by the hatchery personnel and district staff at Sault Ste. Marie. 

 Preliminary results from the experimental work were most encouraging. Plans 

 were made to continue with studies in 1966 and to include the relative carrying 

 capacities and survival of transplanted fish in comparison with established trans- 

 portation techniques.
