LAKE TROUT 225 



even though in 1899 the yield of Lake Trout was ten million 

 pounds (10,611,588). To-day the United States Bureau of 

 Fisheries is doing its utmost to help maintain the supply, and 

 in 1913 distributed 30,231,524 eggs and young of the Lake 

 Trout. 



"Lake Trout spawn on the reefs, and at other times live 

 in deep water. In Lake Superior the spawning season begins 

 in late September. In Lakes Huron and Michigan, the 

 height of the season is early November, and spawning con- 

 tinues until December. The spawning-grounds are on the 

 reefs of 'honey -comb' rock, 10 to 15 miles off shore, and in 

 water from 6 to 120 feet deep. The number of eggs pro- 

 duced is not large. A 24-pound fish produced 14,943 eggs, 

 but the usual number does not exceed 5,000 or 6,000." (Jor- 

 dan and Evermann.) 



The range of this fish is from New Brunswick and Maine 

 westward throughout the Great Lakes to Vancouver Island, 

 B. C, and northward to Labrador, Hudson Bay, and north- 

 ern Alaska. 



Deep- Water Fishing for Lake Trout. — "The Sisco- 

 wet of Lake Superior is taken by the commercial fishermen 

 in very deep water, the nets being lifted by steam-power. 

 The nets are set well out toward the centre of the lake, at 

 depths frequently as great as 500 feet. About forty nets, 

 each over 600 feet long, are set in one 'gang,' constituting 

 practically a single gill-net considerably over four miles in 

 length. Each end of each gang is buoyed. 



"The average steam fishing-boat attends to five gangs 

 of nets, lifting one each day. Each gang, therefore, remains
