Opc'r.-itiiiiis ill tlie Oregon lu'ld were coiiducted at six iieriiiaiicnt stations, 

 and olforts were directod toward the niaiiitt'iiaiico of llie run of salmon in the 

 States of Orogoii, Idaho, and Washiii^;t()ii. The fisli-cullural W(»rk at these 

 stations was c-oncerncd clnelly with the propaj^ation of tlie cliiiiook and steel- 

 liead sahnons, though small numbers of the silver, chum, and sockeye salmon* 

 were also handled, as well as several species of trout. The total egg collections^ 

 amounted to only 22,500,01)0. as compared with appmximately 02.000,000 la 

 the preceding year. The very decided falling off in results is attributed to- 

 the extremly low-water stages whieh prevaileil in nearly all streams through- 

 out the field. As in previous reports acknowledgement is made of the very 

 hearty cooperation afforded by the Oregon State Fish and Game Commission,, 

 both linancially and otherwise. 



Clackamas {Orcg.) station. — Owing to repeated failure of egg collecting 

 operations in the Chickamas River during the seasons of 1928 and 1929, no- 

 racks were installed ; and it transpired that such action was justifiable, since only 

 a very few cliinook salmon ascended the stream. To offset this failure to secure' 

 spawn 1,230,000 eggs of this species were transferred from other points and 

 the resulting fish were reared to the No. 2 fingerling stage before l.beration.. 

 All eggs collected at the upper Clackamas substation were also hatched here ;: 

 and the fish produced therefrom were returned, in the No. 2 fingerling stage,, 

 for planting in the waters from whicli they were derived. Shipments of steel- 

 head, rainbow, and brook trout eggs were also handled. Facilities at this 

 station have recently been improved by the installation of a cold-storage room 

 for the preservation of fish food. This room has a capacity for holding 2 tons 

 of meat. In cooperation with Oregon Game Commission fishery exhibits 

 were displayed at the State fair at Salem, Oreg., and at the Pacific Coast 

 International Stock Show at Portland. Both exhibits occasioned favorable 

 comment. 



Little White Salmon {Wash.) sxuhstation. — The construction of the cold- 

 storage plant at this station, undertaken prior to the beginning of the year, was 

 completed. This plant which provides for the freezing of 2 tons of fish in 24 

 hours and has a holding capacity of 70 tons, will be used for the storage of 

 food for both the Little White Salmon and Big White Salmon stations. A 

 number of skiffs were constructed for use in this and in other fi :4ds. Chinook- 

 salmon egg collections were the poorest in years, only 9,8.30.000 being secured 

 as compared with 20,172,000 in 1928, and 26.600,000 in 1927. Increased com- 

 mercial fishing is given as one reason for this. About 500,000 chiun-salmon 

 eggs were also collected and nearly 2,000.000 chinook eggs were transferred 

 here from other collecting points. A normal percentage of hatch was secured 

 and the resulting fry were held by the stacked-tray system. The young fish 

 were fed on horse meat and spawned-out salmon preserved by freezing, about 

 8 tons of the latter being used for food in the course of the season. 



Big White Salmon (Wash.) substation.- — ^The usual preparations were made 

 for the collection of chinook-salmon eggs in the Big White Salmon River and 

 Spring Creek. The latter was formerly barren of salmon. l)ut through the 

 efforts of the station in making frequent and heavy plants of young fish, a run 

 of salmon was established and has been built up to very fair proportions. The 

 season's collection of eggs proved disappointing, only 5.845,000 being obtained. 

 P>y means of the station truck, the eggs collected in the Big White Salmon 

 River were siiccessfully transported from the racks to the hatchery in the green 

 state. Five hundred and fifty thousand of the eggs were transferred to the 

 main station at Clackamas. From the eggs retained a normal percentage of 

 hatch was secured and nearly 5,000,000 fish were reared to No. 2 and No. 2^2 

 fingerlings for liberation in the Columbia River. Spawned-out salmon to the 

 amount of 4 tons, preserved at the Little White Salmon station by freezing, 

 was fed to the young fish in connection with 7,000 pounds of horse meat and" 

 liver. In addition to the propagation of chinook salmon nearly a million brook, 

 rainbow, and steelhead eggs were incubated and the product reared. Most of 

 these were cared for as a courtesy to the Klickitat Game Commission, and the 

 resulting fingerlings were liberated by the commission in mountain lakes and' 

 streams in this county. Increased illegal net and troll fishing ol¥ the mouths- 

 of the Little White Salmon and Big AVhite Salmon Rivers at the time adlilt
