LXVI REPORT OF COMMISSIONER OF FISH ATs^D FISHERIES. 



points in future, bnt it will be necessary to construct temporary hatch- 

 eries, so that eggs may be eyed before being transferred to the station. 



Baird Station, California (Livingston Stone, Superintendent). 



Early in July the rack to prevent the ascent of the salmon was com- 

 pleted and a wagon and foot bridge was built across the river. A new 

 current-wheel, spawning-house, salmon corrals, etc., were constructed 

 by the station force. 



The first ripe salmon were captured on August 21, and eggs were 

 taken daily from that time to September 16, the total collection aggre- 

 gating 5,000,000. These were held until the eye-si^ots appeared, when 

 they were shipped to the State hatchery at Sisson, Cal. The last of 

 them Avere disposed of by October 20, and as it had been decided not 

 to make collections from the late run of salmon arrangements were 

 made for the transfer of a large part of the equipment and the force to 

 Battle Creek Station. During December over 2,000,000 salmon eggs 

 were forwarded to Baird from that station, to be hatched and liberated 

 in McCloud Kiver. To prevent the crowding of the troughs, 1,000,000 

 of the fry were liberated in January; the remainder were divided 

 into four lots and experiments were tried for the purpose of determining 

 what preparation of food would produce the best results. The first lot 

 was fed on liver exclusively, the second on a mixture composed of three 

 parts liver to one of mush, the third on e(pial parts of mush and liver, 

 and the fourth on three parts mush to one of liver. The fish fed on 

 liver exclusively were found to exhibit a marked superiority in size and 

 strength over those fed on the mixtures, but there was very little 

 difference in the condition of the three lots fed on liver and mush in 

 varying proportions. 



Early in June the work of commencing a new rack and bridge for 

 the coming season was undertaken, and the indications jwint to a very 

 large run of salmon.

 tion of eggs, and the maximum, minimum, and mean temperatures of 

 air and water, by months :
