No fisii-cultural operations were carried on at the Baker Lake, 

 Wash., substation. The salvaging of material from the hatchery 

 building, which collapsed under heavy snow February 22, 1937, and 

 the remodeling of the sawmill building into a hatchery, was carried 

 on by C. C. C. enrollees. This station, which was formerly used for 

 the propagation of salmon, will now be used for rearing trout to stock 

 the waters of Mount Baker National Forest. 



The Moimt Rainier, Wash., substation collected and received 

 from other stations approximately 1,000,000 trout eggs of various 

 species. Most of the resulting fish were liberated in waters of Mount 

 Rainier National Park and the Snoqualmie National Forest. From 

 the rearing ponds at Spokane, Wash., 300,000 large fingerling trout 

 and graylings were distributed. Most of these fish were assigned to 

 the Conservation Departments of Washington and Idaho. 



In the Olympic Peninsula, the Quinault, Wash., hatchery collected 

 2,000,000 sockeye salmon eggs instead of the yearly average of 

 10,000,000 and reared the entire output of both salmon and trout to 

 larger fingerlings before liberating them. The dam from which the 

 hatchery receives its water supply was rebuilt. 



The substations located at Duckabush and Quilcene, Wash., con- 

 centrated on the propagation of chum salmon, but a number of other 

 species of salmon and trout were also handled. The steelhead trout 

 run in the Duckabush River was very small and no effort was made 

 to collect the eggs of this species. 



MARINE SPECIES 



The Woods Hole, Mass., station collected 506,824,000 winter 

 flounder eggs and distributed 452,663,000 fry. In view of the favor- 

 able reports from previous plants of floimder fry in Long Island 

 Sound and Narragansett Bay, a number of fry were planted in these 

 waters, but the largest percentage were liberated in the coastal waters 

 of Massachusetts. Several hundred feet of steam pipe between the 

 boilerhouse and hatchery building was renewed. The Massachu- 

 setts Department of Conservation was allowed the use of space in the 

 hatchery for the purpose of carrying on an experiment in the feeding 

 and rearing of young lobsters. During June, 94,600 lobster fry were 

 liberated. 



At the Gloucester, Mass., station several spawn-takers were placed 

 aboard commercial fishing vessels for the purpose of collecting haddock, 

 pollock, cod, and flounder eggs. The total number of eggs taken 

 exceeded 5,112,000,000, which was more than 16 percent over that of 

 1937. Of this number, slightly over 626,000,000 were propagated at 

 the hatchery. The balance, after fertilization, were planted directly 

 on the spawning grounds. The lobster-cultural work was carried on 

 in cooperation with the Massachusetts Department of Conservation. 

 From 273 seed lobsters approximately 2,503,000 eggs were taken and 

 placed in hatching jars and 300,000 young lobsters in the fourth larval 

 stage were liberated in Massachusetts coastal waters. Experiments 

 in the feeding of fish instead of meat to lobster fry were carried on. 

 Of the several lands of fish fed, haddock seemed to be the most 

 suitable. 



The Boothbay Harbor, Maine, station collected cod, haddock, and 

 flounder eggs. The eggs of the two former species were fertilized and
