U. S. BUEEAU OF FISHERIES 



through the Lyre River from Puget Sound, eyed eggs of that species to the 

 number of 1.028,350 were transferred to tlie station from the Quinault field, 

 with the view of rearing the resulting fry to the fingerliug stage before liberat- 

 ing them. The young fish were fed from April 26 to June 27 when the result- 

 ing fingerlings, amounting to 953,500, were planted in the lake. Returns in the 

 Lyre River are expected this summer from the first fish liberated in Lake 

 Crescent in June, 1927, and accoi'dingly a close watch is being maintained. 



QXJTNAULT (WASH.) STATION 

 [Marcus S. Meter, Superintendent] 



The fish-cultural work of this station is directed principally to the propaga- 

 tion of sockeye salmon. During the fall spawning season from November 3 to 

 December 30, 15,300,000 eggs of this species were collected, together with 

 3.000,000 of the silver salmon and a small number of chinook-salmon eggs. 

 Practically throughout the spawning season the water in the streams of the 

 region was at an extremely low stage. This caused many of the fish to spawn

 Wash. Installed to overcome loss of young salmon in ditches 



along the shores of the lake and rendt-red the movement of fish canoes and 

 equipment a somewhat laborious task. In order to provide sufficient room for 

 the development of the sockeye-salmon fry it was found necessary to transfer 

 the silver-salmon eggs in the eyed stage to other stations for the completion of 

 incubation. The stacked-tray system for handling the fry was used with excel- 

 lent results. A large pool just below the falls in Falls Creek was screened off 

 and used for the rearing of 500,000 of the fingerling salmon after filling the 

 hatchery and station ponds to capacity. 



Extensive repairs were made to the hatchery building early in the fiscal year. 

 The foundation being bady rotted, it became necessary to renew foundation 

 posts, sills, floor joists, and flooring. While such work was going on, the 

 hatching troughs were removed to the station workshop ; and, after completing 

 repairs to the building, new trough horses were constructed and the troughs 

 were again set up and painted. A 65-foot section of the flume supplying water 

 for grinding fish food was rebuilt; and a temporary flume, 200 feet in length, 

 was constructed from the hatchery head trough to connect with the flume just 

 above the hatchery settling tank. The purpose of this flume is to supply water 

 to the hatchery while a new concrete settling tank was in course of construction.
