 E. TiNSLEY, Esq., 



Superintendent of Game and Fisheries, Toronto. 



Dear; Sir, — I beg to report on the work of the Biological Station, Georgian 

 Bay, as follows: 



During the past searon the station was open for workers from June 1st to 

 September 10th. Mr. A. R. Cooper, B. A., continued his previous work on the life 

 history of parasites affecting fresh water fishes. Mr, A. D. Robertson took charge 

 of the collection of mollusks, tlie latter being collected systematically for the first 

 time. Dr. A. G. Huntsman supervised this work during the month of August 

 and the collection is now being worked over by Mr. Robertson as a post-graduate 

 student. Mr. E. M. Coatsworth made collections of fiat-worms and leeches and 

 worked out a provisional classification embracing both parasitic and free living 

 forms. The work on the species of fish and their distribution was continued, and 

 the thanks of the staff are due to the Department for permission to use certain 

 nets for this purpose. 



Yours respectfully, 



B. A. Bensley, 



Assistant Director. 



REPORT OF THE WORK DONE AT THE BRANTFORD BASS POND 

 DURING THE SEASON OF 1910. 



To the Superintendent, Gajne and Fisheries Department, Parliament Buildings, 

 Toronto, Ontario. 



Sir,— I herewith beg to submit my second annual report in connection with 

 work done, and the result thereof, at the Provincial Experimental Pond here. 



The Bass fingerlings number over fifty thousand, which were transplanted 

 by myself in different inland waters. The mortality through transit was not 

 noticeable. 



On April 22nd, 83 parent fish, 3'5 male and 48 female, were deposited in the 

 pond, with the result that on the 17th May, they began in several instances to 

 build their nests. The weather this year was not nearly as favorable as last, owing 

 to the continued low temperature. 



Some sixteen nests were built and hatched, twelve of which were in sheltered 

 nests, and four on the natural gravel beds. The dimensions of the ponds are 155 

 feet by 135 feet, total area 580 feet of hatching space, and this being divided into 

 2C feet, gave us the sixteen nests, which was the only available place in which 

 nests could be successfully built and hatched. The total hatched and reared from 

 those sixteen nests averaged a trifle over three thousand per nest. 



The Department are to be congratulated upon the success this year, and the 

 activity they have displayed in connection with the establishing of the new hatch- 

 ery at Mount Pleasant. 



Yours truly, 



J. T. Edwards.
