PROPAGATION AND DISTRIBUTION OF FOOD FISHES, 1&22.

furnish in connection with the flow from the pond a water supply 

 of ample volume and, within reasonable limits, under control as to 

 temperature throughout the year. It is expected that during the 

 coming year the site will be sufficiently developed to permit of egg 

 collections being undertaken successfully. 



NASHUA (N. H.) STATION. 



[Waldo F. IIdbbard, Superintendent.] 



The 5'ear's distribution of fish from this station amounted in the 

 aggregate to 2,008,030 of the following species: Brook trout, rain- 

 bow trout, lake trout, landlocked salmon, small-mouthed black bass, 

 yellow perch, and pike perch. With the exception of some 10,000 

 rainbow-trout eggs and 125,000 brook-trout eggs, which were ob- 

 tained from the small number of brood fish maintained at the sta- 

 tion, and the small-mouthed black bass resulting from natural spawn- 

 ing in Sunapee Lake, all of the fish distributed were produced from 

 eggs purchased from commercial fish-culturists or transferred from 

 other stations. The pike perch and yellow perch were received from 

 the Vermont station on Lake Champlain, the lake trout from 

 Holden, Vt., the landlocked salmon from Green Lake, Me., and the 

 rainbow trout from Wytheville, Va. The brook-trout eggs were 

 purchased from commercial fish-culturists in the New England 

 States. There were no unusual circumstances attending the incuba^ 

 tion of the eggs or the distribution of the resulting fish. 



In discussing the affairs of this station it is considered proper to 

 mention the deplorable condition of the bureau's property. The 

 hatchery building — a temporary structure, built with no view of 

 permanency — is at present a very dilapidated affair. The rearing 

 ponds, which were originally constructed with plank sides, are in a 

 similar state of decay and are of no value to the station. If the sta- 

 tion is to continue its usefulness, funds for rather extensive repairs 

 must be provided at an early date. 



COMBINATION TROUT AND POND FISH-CULTURAL STATIONS. 



The five stations in this group produced for distribution during 

 the year 5,447,922 eggs, fry, and fingerling fish, as compared with 

 4,654,835 in 1921. The aggregate output by species for each of the 

 two vears is indicated in the followino- table : 



These" figures represent such species of fish as are actually pro- 

 duced at the stations and do not include fishes produced from eggs 

 transferred from other points. The inclusion of such species would
