had to be taken on a hand car to Thrall, where they were transferred to 
the Southern Pacific Railroad, and then taken to Sisson. 
The operations at this station were very successful. There were col¬ 
lected 2,000,000 fine rainbow trout eggs. The fertilization was good. 
Mr. Requa spawned the fish and cared for the eggs en route to Sisson. 
Shovel Creek Station furnished 1,100,000 eggs. A larger number of 
eggs would have been taken, but a rise of water in the creek, which ran 
over the racks, allowed a great many fish to escape. Ten per cent of the 
eggs taken at Shovel Creek were hatched there, and the fry distributed 
in the creek. We took 5,000,000 eggs from the pond fish. This was the 
largest number of eggs taken from the pond fish since the pond work 
was begun. These, with the eggs from the Klamath River stations, gave 
us a total of 8,000,000 rainbow trout eggs for the season. They were 
hatched in good condition, and the fry show the benefit of the new 
arrangement of the troughs. Taking them as a whole, they are the finest 
lot of fish that were ever handled at this station. 
The output of salmon fry for the season of 1909-1910 was lighter than 
it has been for several years past, owing to high water in the rivers and 
streams tributary to the Sacramento River, on which the United States 
Bureau of Fisheries stations are located. The high water washed out 
the racks and a large number of spawning salmon escaped. This caused 
the take of salmon eggs to be short for this season. We received 
22,500,000 as the total take of the season. These were given extra care 
during the hatching period, and the fry were liberated under the most 
favorable conditions. 
They will give better results than a larger number of eggs would if 
not handled so systematically. We have built a couple of new ponds 
in the last two years, making a total of forty-seven ponds and nurseries 
on the grounds. 
The total number of fish on hand in the ponds at Sisson Station Sep¬ 
tember 1, 1910, is as follows: 
Rainbow trout: 
Adults - 11.000 
Two years old___ 2,000 
One year old- 8,000 
Fry -40,000 
Total _01,000 
Eastern brook trout: 
Adults - 7,000 
Two years old___ 1,000 
One year old-:- 3,000 
Fry -25,000 
Total 
— 36,000
