44 REPORT OF COMMISSIONER OF FISH AND FISHERIES. 



Native and rainbotc trout. — A substantial trap having been built at 

 Twin Lakes, it was hoped that a large collection of eggs of the black- 

 spotted, yellow-liniied, and rainbow fronts would be secured. Very few 

 fish were taken, however, either by the State or the station trap, probably 

 because of very cold and rough weather prevailing during the spawning 

 season. The total egg collections were G2,C00 black-sitotted (43,100 i'roiii 

 Twin Lakes and 19,500 from the station fish), 20,500 yellow-finned 

 from Twin Lakes, and 13,500 rainbows (11,000 from Uneva and 2,500 from 

 the station stock. 



At the close of the year the stock of eggs and fish was as follows : 



Baiim) Station, California (Livingston Stonk, Superintendent). 



Work at this station during the year was couliued, as in i)ast years, to 

 thequinnat salmon {Oncorhynchus tschawytscha). There are two runs 

 of this salmon each year, one in the summer and one in the fall. Tlie 

 summer run spawn from about August 20 to kSeptember 20; the fall run 

 spawn from about October 25 to the first week in December. By rea- 

 son of the fact that the close season in California does not begin 

 (according to the law of that State) until September 1, thereby permit- 

 ting the operation of seines until that time, very few, comparatively, of 

 the summer run of salmon reach this statiou. 



On August 24 the summer fishing and spawning season opened with 

 the taking of 90,000 eggs and continued until Sei)tember 30. The total 

 number of eggs taken from the 816 fish secured was 3,294,300, an 

 average yield of 4,037 eggs per fish. The fall run began October 22 in 

 the midst of seven days' storm, which commenced on the 17th and lasted 

 until the 24th. The McCloud Eiver rose rapidly, and on the night of 

 the 23d a portion of the rack was carried away, notwithstanding the 

 fact that several men were kept on it day and night to keep it clear of 

 leaves and dirt. This caused a large number of breeding salmon to 

 escape through the breach. The river was closed again on the 27th, 

 but it was too late to retrieve the great loss of breeders occasioned by the 

 accident to the rack. 



The total number of eggs taken up to November 23, when the fall run 

 ceased, was 1,098,800, an average of 4,300 per fish. 



During the fiscal year 3,520,300 eggs were sent to the State hatchery at 

 Sisson, Cal., and 150,000 to the Societc d'AccMmatation, Paris, France. 

 From the remainder, 400,000 young salmon were deposited in McCloud
