EEPORT OF COMMISSIONER OF FISH AND FISHERIES. LXXIII 



g. The Brook Trout {SalveUnus fontinalis). 



Nortliville Station. — In view of the fact that the brook trout has con- 

 stituted one of the principal objects of consideration by the Fish Com- 

 missioners and fish culturists in the Northern States, it has not, as ex- 

 plained in previous reports, received much attention from the United 

 States Fish Commission. A small supply of breeders is, however, main- 

 tained b\' Mr. Clarke at the North ville (Mich.) hatchery, and the product 

 has been distributed to a few special localities — for the most part sent to 

 Europe, in exchange for other species. The disposition in question will 

 be found recorded in the table of distribution in Mr. Clarke's report. 

 There were 473,000 eggs obtained, 357,000 eggs shipped, and 50,000 fry 

 hatched. Those shii)ped to Euiope invariably arrived in good condition. 



/(. The Shad {Clupea sapidissima). 



Quantico Station. — Three stations for the propagation of shad were 

 operated on the Potomac Eiver during the season of 1882. 



The Fish Hawk, under command of Captain Tanner, was stationed at 

 Quantico and collected eggs from that section of the river lying south 

 of Indian Head. In addition to the M'ork of shad propagation, many 

 millions of eggs of the river herring were hatched and planted in local 

 waters. Of the product 2,000,000 fry were sent by car No. 2, and planted 

 in the Colorado Eiver, at Austin, Tex., the experiment being made with 

 the expectation that this species could be acclimated in these waters, 

 and from its wonderful fecundity become an important addition to the 

 resources of the river. Should these anticipations be realized, it is pro- 

 posed to plant this si)ecies largely in all the tributaries of the Gulf of 

 Mexico. 



In this connection it may be mentioned that the first Potomac shad 

 of the season was said to have been taken on the 21st of February; this 

 was at White Point, Va., nearly seventy miles below Washington. 



A summary of the work done is as follows: 



Number. 



Eggs taken and impregnated 2, 407, 000 



Shad fuinislied for distribution 800, 000 



Herring furnished for distribution 2, 000, 000 



Shad deposited in local waters 1, 755, 000 



Herring deposited in local waters 7, 883, 000 



For fuller details in regard to the work of the station, reference is 

 made to the rei)ort of Captain Tanner. 



Navy-yard Station. — This station was in charge of Lieut. W. M. Wood, 

 commanding the Lookout, Master W. C. Babcock and Master A. C. 

 Baker being in immediate charge of the hatchery. Eggs for the sup- 

 ply of this station were collected from Moxley's Point and the gillers in 

 that section of the river around Fort Washington; the Lookout being- 

 employed to collect and transfer the eggs to the station. During the 

 season 21,820,000 shad eggs were collected, which yielded 17,935,000 

 fry. Of these 3,050,000 were deposited in local waters, 14,444,000 turned
