*297,000 eggs of this lot shipped from station. 



The total collection exceeded that of the previous year by nearly 

 1,000,000. The superintendent and foremen performed all the work of 

 taking and fertilizing the eggs, and, except those from Musgrove and 

 Decker lakes, they were of excellent quality, considering the conditions 

 under which they were taken. The large loss on those from Musgrove 

 Lake was undoubtedly due to the necessity of crowding the fish into a 

 very small pond and holding them there for several weeks to ripen. 

 The poorest eggs were obtained from fish that had been held a consid- 

 erable time before spawning. All of the eggs were transferred to the 

 Leadville Station to be hatched, and during the spring 581,000 of the 

 fry were distributed in public waters and supplied to applicants in 

 Colorado and Utah; 930,900 were turned over to the owners of the 

 various lakes from which collections were made, and 340,000 were held 

 for distribution in the fall. Shipments of the eyed eggs, aggregating 

 172,000, were made in January and February to private hatcheries in 

 Utah, Montana, Washington, and California, and 150,000 were trans- 

 ferred to other stations of the Commission. The capacity of the hatch- 

 ery was severely tested by the large collections, and in April it was 

 found necessary to erect a number of temporary troughs. The finger- 

 lings on hand at the beginning of the year (241,465) were carried in 

 troughs and ponds until September, with a loss of 69,365, when they 

 were distributed in public waters in the Northwestern States. 



Of the Loch Leven trout fry on hand in July, 8,000 were distributed 

 in October, leaving 2,000 on hand January 1; these will beheld for 

 brood stock. There were also 4,170 two-year olds on hand in July, but 

 severe losses during the summer reduced the number to 1,870 at the 

 close of the year. The brood-fish commenced spawning October 14, 

 and during the fall produced 53,100 eggs, which hatched with a loss of 

 9,720, or about 18 per cent. When the eye-spots developed 15,000 of 

 the eggs were shipped, and at the close of the year there were 25,100 fry. 



On September 1 the 21,695 fry remaining from rainbow-trout eggs 

 hatched during the summer were distributed with little loss. In April 

 26,800 eggs were collected from Loveland Lake, but the majority of 

 them were lost in incubation. This was undoubtedly because the 

 fish were held in a small crate for some time before they were ready to
