ST. JOHNSBURY ( VT. ) STATION AND SUBSTATIONS. 

 [A. H. DiNSMOREj Superintendent.] 



The fishes propagated at this station and its auxiliaries at Holden, 

 Vt., and York Pond, N. H., included brook, lake, rainbow, and Loch 

 Leven trout, landlocked salmon, and steelhead, the total annual 

 output for the group amounting to nearly 1,500,000 eggs, fry, and 

 fingerling fish. Owing to shortage in operating funds the propaga- 

 tion of pike perch at the S wanton (Vt.) substation was omitted. 



ST. JOHNSTSVEY (VT.) STATION. 



Of the 1,323,400 brook- trout eggs acquired for stocking the St. 

 Johnsbur}' hatchery 450,000 in round numbers were purchased from 

 a commercial trout establishment. The- I'eimnnder wis collpcted 

 from fish taken in Darling Pond and Lake Mitchell, in Vermont, on 

 the same terms as last year, the bureau collecting and incubating the 

 eggs and receiving as compensation one-third of the eyed eggs pro- 

 duced. The fry resulting from the remainder were placed at the 

 disposal of the owners of these waters. The work with this species 

 also included the incubation of 100,000 eggs that were purchased 

 and delivered at the hatchery by a local fish and game club whose 

 members distributed the resulting fry in various waters of the re- 

 gion. 



Other egg receipts were 238,350 of the lake trout, derived from 

 collections at Lake Dunmore, Vt. ; 20,350 landlocked-salmon eggs, 

 transferred from the Craig Brook (Me.) station; 10,350 Loch Leven 

 trout eggs, acquired by exchange from a commercial fish-culturist ; 

 and 49.500 steelhead eggs received from the Washougal ("^Yash.) 

 collecting station. Some of the lake-trout eggs were reshipped to 

 the York Pond auxiliary, and a consignment of 50,000 was for- 

 warded to the Nashua (N. H.) hatchery. The remainder was 

 hatched and distributed as fry in suitable local waters. The fry 

 resulting from the landlocked-salmon eggs were transferred to York 

 Pond to be reared, and the product of the Loch Leven and steelhead 

 eggs was on hand at the close of the fiscal year. 



On account of limited funds and the need of all possible additional 

 help for the development of the York Pond substation, no work in 

 the propagation of smallmouth black bass was undertaken during 

 the year. 



HOLDEN (VT.) SUBSTATION. 



The outcome of the year's work in fish culture at tliis substation 

 was very satisfactory. Only normal losses of stock were sustained 

 and an entire absence of the affection that in recent years has caused 

 such heavy mortality among the eggs and young fish gives ground 

 for the hope that the difficulty has been solved through the appli- 

 cation of the recently devised method of aerating the hatchery water 

 supply. 



The small stock of fingerling fish of various Sipecies on hand at 

 the beginning of the year was distributed in the early fall, and 

 during October and November the bureau and the State fisheries
