REPORT OF COMMISSIONER OF FISH AND FISHERIES. XXXVII 



each year, it is believed that the large uumber of fry planted in the last 

 few years will have an appreciable effect, as correspondeuts from various 

 points report the presence of large numbers of young lobsters. 



Shad work commenced on Albemarle Sound in Marcb, where the 

 steamer Fish Hawk had been ordered for duty. At the close of the 

 season there she proceeded to the Delaware, and continued in this work 

 until the end of June, collecting over 72,000,000 eggs. These, with the 

 large number taken at Bryan Point on the Potomac Eiver and at 

 Havre de Grace on the Susquehanna, produced over 235,000,000 fry, 

 which were liberated in the numerous shad streams emptying into the 

 Atlantic Ocean. 



The output of trout, salmon, bass, and crappie from the inland sta- 

 tions was very satisfactory. These fish are now abundant in many 

 parts of tlie country to which they are not indigenous. At Leadville, 

 Colo., where a station was originally established for the propagation of 

 the black-spotted trout, during the i)ast season over 3,000,000 eggs of 

 the brook trout were collected from lakes controlled by private parties. 



The grayling work in JNlontana was very satisfactory, and the indi- 

 cations are that large numbers of these eggs can be collected annually, 

 which will permit the introduction of this valuable fish in most of the 

 States where brook trout are now found. 



RESULTS OF FISH-CULTURE. 



Although no systematic effort is made to investigate the various 

 streams and lakes stocked with new varieties of fish, the ofiice is in 

 receipt constantly of communications showing the result of their intro- 

 duction. Particularly gratifying rej)orts have been received from Min- 

 nesota with reference to the introduction of steelhead trout in Lake 

 Superior. Mr. L. E. Baldridge, foreman of Duluth station, Minnesota, 

 reports, under date of March 13, 1899, that large numbers of steelhead 

 trout, varying in length from 7 to 28 inches, were caught during the 

 summer and fall of 1898 along the north shore of Lake Superior, 

 between Duluth, Minn., and Kossport, Ont. Mr. D. J. Greensword, 

 treasurer of the Duluth Fly-Casting Club, informed him that a number 

 of members of his club took over 400 steelhead trout from Sucker Eiver 

 in two days' fishing with hook and line and that he had captured 85 

 in a single day. He further states that not less than 2,200 steelheads 

 were taken in the same manner from the French and Sucker rivers 

 and that they take the fly as readily as do the brook trout. The fisher- 

 men operating gill nets along the north shore for lake trout have also 

 captured a number, varying from 14 to 18 inches in length. It appears 

 that the steelheads caught in nets had slipped through the nets until 

 the twine was just forward of the dorsal fin, which would indicate that 

 they were too small to be taken in very large numbers in the large-mesh 

 nets used for the capture of lake trout. The steelheads are probably 

 as plentiful in other rivers along the north shore, which are not visited 

 on account of their remoteness from Duluth.
