PROPAGATION AND DISTRIBUTION OF FOOD FISHES, 1931 673 



obtained from Minatare and McDowell Lakes, and black bass were transferred 

 here from the Miles City (Mont.) substation. A total of 92,825 fingerling and 

 adult pond fishes, consisting of catfish, bream, black bass, and yellow perch, 

 formed part of the station's output for the year. 



SPRINGVILLE (UTAH) STATION 

 [Claudius Wallich, Superintendent] 



The collection of eggs from rainbow trout brood stock, numbering 2,951,000, 

 exceeded that of the preceding year; and it would have been much larger had not 

 a cloudburst caused the escape of about 900 spawning fish. As approximately 

 3,000 first-year spawners will be available from growing stock next fall, however, 

 the station will doubtless be in a position to produce a continuously increasing 

 output of this species. The year's distribution of fingerling fish amounted to 

 1,910,800 as compared with a production of 1,619,000 last year. The distribution 

 was effected bj^ making a considerable number of trips with the State tank truck 

 and 74 messenger trips, the total mileage involved amounting to 30,200. Only 

 about one-fifth of the fish shipped were as small as No. 2}i fingerlings; the 

 remainder consisted of No. 3 fingerlings and larger. 



So far as the resistance of the Indians is concerned the work of collecting 

 black-spotted trout eggs in the Pyramid Lake (Nev.) field is now on a fairly 

 sound basis. During the spring of 1931 4,877,000 of these eggs were secured. 



Work in the Fish Lake (Utah) field was conducted as usual in cooperation 

 with the State. From this source the bureau derived 1,773,000 brook trout eggs 

 and 733,000 rainbow trout eggs. The State, as per agreement, received a larger 

 share. A total of 2,912,000 eyed eggs were shipped from the Springville station 

 during the year. Of this number 990,000 were black-spotted trout eggs, taken in 

 Pyramid Lake; 927,000 were rainbow and brook trout eggs, from the Fish Lake 

 field; and 995,000 were rainbow trout eggs, from the station brood stock. 



NEW ENGLAND TROUT STATIONS 



Outstanding accomplishments at these stations included the col- 

 lection of more than 4,000,000 brook trout eggs at the Craig Brook 

 (Me.) station and of more than 7,000,000 brook trout eggs at the 

 York Pond (N. H.) station. The York Pond station is being enlarged 

 to provide adequate fish-hatching apparatus and ponds. 



BERKSHIRE (MASS.) STATION 

 [E. P. Thompson, Acting Superintendent] 



Drought conditions cut down the water supply, making it necessary to dig 

 for an additional supply. Four ditches were cut into the steep bank back of the 

 springhouse. These ditches were about 50 feet long and varied in depth from 

 3 feet at the entrance to 15 feet at the back end. Approximately 100 gallons a 

 minute were made available by these excavations. 



The station brood stock of brook trout yielded 750,000 eggs, of which 308,000 

 were shipped to the Nashua (N. H.) station and 2,000 to the Bruce Museum at 

 Greenwich, Conn. There were 334,715 brook trout fingerlings, yearlings, and 

 adults, 4,325 yearling catfish and 366 smallmouth black bass fingerlings and 

 adults distributed. There were 35,042 brook trout fingerhngs and yearlings on 

 hand at the end of the season. Of the brook trout distributed, 50,800 were 

 furnished to 10 cooperative nurseries. 



A 20-foot space was added to the east end of the garage, making room for two 

 automobiles on the ground floor, and increasing the storage room above. One- 

 half of the Pond A dam, about 60 feet, was rebuilt. A small dam was constructed 

 at the upper end of the lower hatchery, making a small pond between the two 

 hatcheries, and the side walls and top of pond 3 were faced with 8 inches of con- 

 crete. Numerous minor repairs to buildings and equipment were made. On 

 account of frequent rains it was necessary to haul many loads of gravel to keep 

 the roads in condition.
