deposited in commercially-fished waters and 23,790,000 in game-fish waters. 

 In addition, 2,000,000 eyed eggs were supplied Sparrow lake hatchery. 



The unsatisfactory season at the Bay of Quinte station, operated from the 

 Glenora Hatchery, also contributed to the reduced output. 



Whitefish 



The increase in the distribution of whitefish fry from 277,100,000 in 1930 

 to 342,107,000 in 1931 was due, in the main, to the favourable weather conditions 

 in Lake Superior, Georgian Bay, Lakes Erie and Ontario, the hatcheries at 

 Port Arthur, Collingwood, Normandale, Belleville, and Glenora, located on 

 these waters, contributing towards successful spawn-taking operations and 

 increased output. 1,000,000 eyed whitefish eggs were exchanged and 500,000 

 distributed. See Appendix 1, page 76. 



Lake Herring 



A glance at Appendix No. 3 will reveal that the distribution of lake herring 

 fry is on the up-grade. Since 1926 a gradual improvement has been evident, 

 the increase in 1931 over that of 1930 being 9,738,000. The successful spawn- 

 taking operations carried on by the hatcheries at Belleville and Glenora have 

 been largely responsible for this improvement. 



Maskinonge 



The artificial propagation of maskinonge fry is carried out each spring in 

 a portable type of hatchery located on the Pigeon river at Omemee in Victoria 

 county. The bulk of the fry reared has been planted in the Pigeon river and 

 suitable waters in the counties of Victoria and Peterborough. During the year 

 a bulletin entitled "The Maskinonge and Its Conservation" was published by 

 the Department. This deals with the interesting subject of maskinonge culture 

 and may be obtained from the Department on request. 



Black Bass 



The subject of black bass propagation is one which has been given the 

 closest possible attention by the Biological and Fish Culture Branch. The 

 small-mouthed black bass holds the admiration of most anglers and is ranked 

 as the gamest fish that swims. 



Re-stocking depleted waters with small-mouthed black bass or large- 

 mouthed black bass must be viewed from many angles, particularly on account 

 of the large extent of the waters with which we have to deal. The introduction 

 of small quantities of bass-fry or fingerlings to inshore waters of the Great 

 Lakes and such large inland lakes as Nipissing and Simcoe appears unnecessary 

 when we consider the numbers of bass fry produced in these waters annually 

 by natural propagation. Suitable restrictive measures on inshore waters and 

 large inland lakes pertaining to bag limit, size limit, season and closed areas 

 should suffice. No one remedy will succeed in reaching our objective, namely, 

 to maintain and, if possible, to improve the bass fishing in Provincial waters. 

 The courses being pursued to establish such conditions are:
