a total output slightly greater than that of last year. The various 

 stations and substations are situated on the more important salmon 

 streams from California to Alaska. 



Afognak (Alaska) Station 



(Frank L. Snipes, Superintendent) 



The chief improvement at this station was the conversion of a storeroom 

 into an office and the addition of tliree rooms to one of the flsli-culturist cot- 

 tages. The escapement of soclieye salmon into Letnik Lake was very 

 small. Of the approximately 5,000 fish that entered the lake, 1,679 females 

 produced slightly more than 4.()00.000 eggs. A satisfactory number of these 

 hatched, and the majority of the young fish were liberated as fingerlings in 

 June. During the spawning season the adult fish were uniformly smaller 

 than in past years, but apparently this did not affect the virility of their 

 eggs. Persistent seining in Letnik Lake for the past three years has vir- 

 tually ridded it of the predatory Dolly Varden trout. There was a satis- 

 factory downstream migration of yearling sockeyes during May and June 

 in 1928. 



Yes Bay (Alaska) Station 



(A. T. LooFF, Superintendent) 



A considerable amount of repairing and replacement has been necessary to 

 keep the station in first-class condition. The entire water-supply line, includ- 

 ing penstock and flume, was recaulked and the trestle repaired. Material 

 has been obtained preparatory to rebuilding the penstock and flume. Shortage 

 of water during the winter necessitated the construction of a temporary 

 brush dam in the river in order to divert water to the intake. An entirely 

 new foundation was built under the woodshed. The floor in the boiler roon?. 

 was renewed. Bad piles in the foundation of the boathouse were replaced, 

 and the metal roof on the ice house was replaced by one of shingles. Con- 

 siderable painting was done also. The reconstruction of the tramway to the 

 landing was completed, and an addition was made to the tramway used for 

 hauling wood. A vat in which nets will be treated was built. The launch 

 Piiffln, which had been out of use, was overhauled and has given good serv- 

 ice. All othei' boats were thoroughly overhauled and repaired where 

 necessary. 



The year opened with over 10,000,000 sockeye fingerlings op hand. These 

 were planted during July and August. Collecting operations yielded a total 

 of slightly over 20,000,000 sockeye-salmon eggs. Water conditions were good, 

 and it is believed that eggs were secured from virtually every salmon that 

 entered the lake. The hatch was satisfactory, and at the close of the year 

 over 16,(X)0,000 fingerlings were retained in the ponds for feeding. The sta- 

 tion also incubated a number of brook-trout eggs, the fry of which were dis- 

 tributed in southeastern Alaska waters. A number of predatory trout were 

 destroyed by seining. 



Baker Lakh (Wash.) Station and Substations 



(.Joseph Kejim.erich, Sui>erinteJi'dent) 



Favorable weather conditions prevailed in this field during the various 

 spawning seasons, and the aggregate of the collections of eggs at all points 

 covered exceeded that of the past two years. This increase was effected in 

 spite of the fact that the run of sockeye salmon to Baker Lake has been negli- 

 gible since the erection of the power dam at Concrete. The superintendent 

 has given considerable thought to the establishment of a run of salmon in 

 streams that are now poorly stocked. Ten streams and the lakes that feed 

 some of them were inspected at various times during the year. In some of 

 the waters there seemed to be little prosi>ect of establishing a run of fish, but 

 in others it was concluded to make systematic plants of fingerlings until 

 favorable results are achieved or the futility of such attempts becomes evi- 

 dent. A very satisfactory run of chinook and humpback salmon ascended 

 Puget Sound streams during the fall of 1927, and it is thought that these
