66 U. S. BUKEAL" OF FISHERIES. 



Under an agreement effected witli the Utah fisheries authorities 

 the station jDarticipated with the State in the collection of rainbow- 

 trout eggs from wild fish in the Fish Lake field during ^May and 

 June and received one-fifth of the proceeds as its share. The quality 

 of these eggs was about the average of the stock secured in this field. 

 After shipping 25,000 eggs to the Manchester (Iowa) station the 

 remainder was hatched, producing 310,000 fry, all of which were 

 on hand at tlie end of June. 



Complete failure attended the efforts put forth to collect eggs 

 in the Kjame Reservoir, near Colton, Utah, where the bureau has 

 recently been making annual plants of rainbow trout with the view 

 to building up an egg-collecting source. The two trips made to this 

 point — one in March and the other in May — failed to disclose the 

 presence of any brood fish whatever. It is feared that this 13-acre 

 lake is almost too small to warrant anj^ profitable returns in eggs, 

 but a few rainbow fingerlings will be liberated there annually for 

 a while and a close watch kept on the results. 



Having failed for two successive years to secure any results from 

 the experiment undertaken some time ago with the object of de- 

 termining the feasibilit}' of holding a brood stock of native trout 

 in the station ponds as a source of egg supply, it was decided to 

 liberate the fish in suitable waters and abandon the attempt. The 

 number of eggs taken in each instance was negligible and their 

 quality was very poor. 



NEW ENGLAND TROUT AND SALMON STATIONS. 



Included under this head are the stations located at Hartsville, 

 Mass., East Orland, Me., St. Johnsbury, Vt., and Nashua, N. H.., 

 together with their several auxiliary substations. During the past 

 year the former station at Green Lake, Me., was reduced to the 

 status of a substation and placed under the direction of the official 

 in charge of the Craig Brook station at East Orland. Although 

 the work in this field was interfered with to some extent by un- 

 seasonable climatic conditions the results attained at these stations 

 were very satisfactory, their aggregate output being more than 100 

 per cent greater than in 1922. 



BERKSHIRE (MASS.) STATION. 

 [W. A. Casleu, Superintendent.] 



The year's fish-cultural work at this station consisted mainly in 

 the incubation of eggs of the brook trout, rainbow trout, and pike 

 perch, and the rearing and distributing of the resulting fish, the ag- 

 gregate output of which amounted to 754,400 fry and fingerlings. 



During the spawning season of the adult brook trout held in the 

 station ponds 203,750 eggs were obtained, of which 149.260, or about 

 73 per cent, were hatched. This low percentage of hatch compares 

 favorably with the results of recent years at this point and is attrib- 

 uted bv the superintendent to the advanced age of the brood stock. 

 A lot of 247,000 brook-trout eggs purchased from the establishment 

 of a commercial trout breeder was apparently far superior in quality 

 to those produced at the station, fry in excess of 240,000 being
