REPORT OF COMMISSIONER OF FISH AND FISHERIES. 



and the second March 16. Fully 75 per cent of the latter died from 

 some unknown cause after hatching. 



On November 4 there were taken at Uneva Lake 24,800 eggs from 5 

 females. These eggs began hatching January 29 ; 73 per cent hatched. 

 They began feeding February 27, and on May 25 there were on hand 

 17,000 fish, or 68^ per cent. June 30, 8,500 were delivered to Searl & 

 Lazenby, in accordance with agreement. There were taken from stock 

 fish 418,400 eggs, 47 per cent of which hatched. The total number of 

 eggs of this species taken was 1,262,100, of which 55£ per cent hatched. 

 Between December 5, 1893, and June 11, 1894, there were distributed 

 23,000 fry and 35,900 yearlings, mostly to Colorado waters. 



Blade- spotted trout. — There were 74,800 eggs taken from stock fish, 

 but they were very poor. It is thought that these fish can not be suc- 

 cessfully kept in small ponds. From October 20 to December 6 there 

 were 10,100 yearlings distributed to various parties for planting in 

 Colorado waters, and 1,000 to Ernest Barthold, of Sheridan, S. Dak., for 

 waters of that State. 



Rainbow trout. — On January 18, there were received from Neosho 

 20,000 eggs. They were in very poor condition, however, and after 

 hatching the fish were weak — would not take food — and on April 19 it 

 was thought best to plant them, and 5,000 were deposited in Lower 

 Evergreen Lake and 6,000 in Lake Creek. On November 12, 1893, 475 

 yearlings were furnished to W. B. Callicotte, of Denver, for his fish 

 ponds, and December 5, 475 were given to Capt. G-. L. Brown, Pine 

 Bidge, S. Dak., which were deposited in Medicine Boot Creek. 



Loch Leven trout. — On January 21, there were received from North- 

 ville 11,200 eggs. After hatching, 80 per cent of them died. Between 

 October 26 and December 18 there were distributed 19,800 yearlings 

 in Colorado, Montana, New Mexico, South Dakota, and Wyoming. 



Yellow-finned trout. — In December, the 2-year-old fish on hand began 

 to die rapidly, and to save them the 700 that remained were planted 

 in Lower Lake on December 13. 



Von Behr trout. — In July, 450 yearlings were distributed in Colorado 

 waters, and on December 24, 1,000 yearlings were deposited in Black 

 Lake. 



The mean air temperature for the year was 35|°, and the mean water 

 temperature 43|°. The highest air temperature was 72°, on July 2, 3, 

 4, 9, and on August 3. The lowest air temperature was on January 18, 

 when it was 16° below zero. 



The eggs, fry, and other stock on hand June 30, 1894, were as follows:
