REPORT OF BOARD OP FISH AND GAME COMMISSIONERS. 31 



TROUT EGG COLLECTION AND DISTRIBUTION. 



During the Avinter and spring of 1910-1911 the Commission olitained 



from the stock fish in the breeding ponds at the Sisson hatchery, the 



following numbers of trout eggs : 



Loch Leven trout 1.200,0CHi 



Rainbow trout 1,100,000 



Eastern Brook trout 750,000 



3,050,000 



In addition to the eggs collected from the stock ponds at Sisson, two 

 spawning stations were operated on the Klamath River, for the collec- 

 tion of wild rainbow trout eggs ; these stations obtained 2,500,000 eggs, 

 which were eyed and shipped to the Sisson Hatchery. A station for 

 the collecting of steelhead trout spawn was also operated at the Snow 

 Mountain Power Company '.s dam, in Eel River, and 1,900,000 eggs 

 were collected there, 300,000 of which were paid to the California 

 Trout Farm Company, which holds the leases for operating at that 

 dam. Three hundred thousand of the eggs taken at the latter place 

 were shipped to the State hatchery at Grizzly Bluff, on Eel River, in 

 Humboldt County, where they were hatched. The fry from this lot 

 were distributed in that county. Seven hundred thousand of the eggs 

 were shipped to the Ukiah Hatchery, which the Commission held under 

 lease. This lot supplied fish for Mendocino, Sonoma, Marin and Lake 

 counties. The balance of the eggs was shipped to Sisson, where they 

 were hatched and planted in public waters. The Commission also 

 operated the Scott Creek spawning station, owned by the county of 

 Santa Cruz, upon a lease, under the terms of which the county hatchery 

 at Brookdale was furnished 500,000 eyed steelhead trout eggs, from a 

 total of 1,300,000 steelhead eggs taken at this station, 600,000 of them 

 being shipped to Sisson, to be used in stocking public streams. 



Owing to unfavorable weather conditions, only 130,000 steelhead 

 trout eggs were collected at Grizzly Bluff, Humboldt County, but the 

 output of that hatchery was increased by the shipment already men- 

 tioned. 



In all, 5,800,000 steelhead trout eggs were collected during the season. 



The season at Tahoe was much later than usual, owing to the 

 excessive snow fall of the previous winter. Operations were begun 

 there in jMay and 3,000,000 Tahoe trout eggs were collected, which Avere 

 hatched at the Tahoe and Tallac hatcheries and planted in the lakes 

 in the immediate vicinity. 



The hatchery at Wawona, Yosemite National Park, was operated as 

 usual, with eggs shipped from Lake Tahoe. 



The total number of trout eggs collected for the year amounted to 

 11,980,000.
