ing year. The collections of brook-trout eggs made by the field station at 

 Big Creek Lakes were somewhat smaller than in previous years and fell- 

 short of last year's figures by approximately 100,000. The station brood 

 stock of brook trout yielded about 300,000 eggs, and a number of eggs were 

 received from other stations, which made possible a satisfactory spring dis- 

 tribution and left 738,000 fingerliugs on hand at the close of the year. Con- 

 siderable trouble was experienced with the eggs taken in Big Creek Lakes, 

 and the losses were heavier than normal. A fairly satisfactory number of 

 eggs was derived from the Loch Leven brood stock, although a serious loss 

 occurred among these fish just at the opening of the spawning season, due to 

 the clogging of a supply pipe to one of the ponds. In the Lost Creek field 

 3,272,000 rainbow-trout eggs were collected, approximately 800,000 of which 

 will be used for stocking parent waters. A shipment of black-spotted trout 

 eggs was received from the Yellowstone Park in July, 1927, and the resulting 

 fry were distributed during the fall. A shipment of early black-spotted trout 

 eggs was received in April. 1928, from the State of Nevada, to be replaced 

 later with eggs from the Yellowstone Park field. In this way fish are brought 

 to the fingerling size much earlier, making it possible to handle them in 

 conjunction with the distribution of brook and rainbow trout. The Saratoga 

 station carries over a large stock of all three species, as its distribution begins 

 late and is carried on through the end of the fiscal year.

The pond system at this station was enlarged and improved. A pipe line 

 will be laid from the source of supply in the city park to the concrete ponds 

 in order to increase the volume of water. A substantial concrete wall was 

 built along both sides of the main-entrance driveway. The usual cooperative 

 fish-cultural work was carried on with the State of South Dakota. The State 

 paid for approximately 2,000,000 brook-trout eggs purchased from commercial 

 dealers, and the station furnished a number of Loch Leven trout eggs, which 

 were repaid with brook-trout eggs from this shipment. Over 1,220,000 fingerling 

 trout were distributed in various parts of the State under this arrangement, 

 and it is felt that the results obtained justify a continuation of such work. A 

 number of commercial fish-cultural projects have been established recently in 

 the Black Hills territory, and the station personnel has been able to render 

 some assistance and advice in this work. A satisfactory take of eggs from 

 the station stock of brook, Loch Leven, and rainbow trout was secured. Almost 

 1,500,000 trout of the three species were distributed from the bureau's stock 

 of fish.

In addition to painting all the station buildings, certain repairs were made 

 to some of the station ponds. The station brood stock of rainbow trout pro- 

 duced over 1,500.000 eggs, of which about 70 per cent hatched. The distri- 

 bution of the young fish resulting from these eggs was in progress at the close 

 of the year. At the opening of the year there were on hand almost 500,000 

 rainbow-trout fry hatched from eggs taken at Fish Lake during the preceding 

 spring. By June 30, 1928, all of these had been distributed with the exception 

 of 10,000, which are being reared to replenish the brood stock. 



Wild rainbow-trout eggs were taken on April 10 at Twin Creeks. As this 

 collecting field is conducted in cooperation with and under the supervision of 

 the State of Utah, the total number of eggs collected (about 6,000,000) was 

 divided between the two agencies, the bureau receiving 1,523,000 eggs of average 

 quality as its share. A number of eggs were shipped to Honolulu, and the fry 

 from the remaining stock are being reared for fall distribution. While the 

 rainbow-trout eggs were being taken, a number of fish that appeared to be 

 silver salmon were noted. These fish were in poor condition, and a number of 

 eggs that were taken and fertilized failed completely to show any development. 



Brook-trout eggs were collected in the Twin Creeks field in October and 

 November. The run of fish was good, and 2,606,000 eggs were secured for the 

 bureau's work in addition to about 4,300,000 allotted to the State. All but
