378 r". S. BUEEAU OF FISHERIES 



800.000 of the bureau*? eggs were shipped to other points. A great many of 

 the fry hatched from the eggs retained at this station died, but those that 

 survived developed well and were reared to fingerliug No. 2 size and distributed 

 in the spring. Eggs from the same lot shipped to the Saratoga station failed to 

 develop this trouble, and the heavy mortality can not be explained. 



On July 28, 1927. a cloudburst caused the Rock Canon Creek to overflow its 

 banks and flood the station grounds, which were covered with a thick layer of 

 mud : but the water supply was so situated that it was not affected, and 

 apparently no fish were lost. 



NEW ENGLAND TROUT AND SALMON STATIONS 



The intensive drain upon waters of the populous northeastern 

 section must be counteracted by the output from the hatcheries 

 situated in Maine, New Hampshire, Vermont, and Massachusetts. 

 The Craig Brook (Me.) station is the only agency in the United 

 States, outside of several of the Maine State hatcheries, that handles 

 the Atlantic salmon. It is also one of the few hatcheries that 

 propagates the landlocked salmon. 



Hartsville (Mass.) Station 

 (E. P. Thompson, Acting Superintendent) 



Attention to routine work and necessary maintenance and repairs to build- 

 ings, equipment, and grounds constituted the only activity, outside of fish- 

 cultural work, of the Berkshire hatchery. The spring-water supply was above 

 normal in abundance during the spring months, and it is believed this was the 

 cause of producing a very satisfactory output of fry and fingerling fish. The 

 station brood stock of brook trout yielded approximately 275,000 eggs, and from 

 these and a lot of eggs purchased from a commercial fish-culturist approximately 

 300.000 fry were obtained. A number of rainbow-trout fingerlings held over 

 from the previous season were distributed, as were a lot of lake-trout finger- 

 lings. The station received 500 adult horned pout and about 100 smallmouth 

 black bass. Weather conditions during the spring appeared to militate against 

 obtaining favorable results from the latter. In contradiction to the usual 

 situation at this station, there was only a normal loss of fry after hatching, 

 and the fingerlings showed good growth and only slight losses at the close of 

 the year. A carload shipment of brook trout to Pennsylvania was made during 

 the spring, and the station distribution was carried on intermittently to the 

 close of the year. 



Craig Brook (Me.) Station and Subst.^tions 

 (George N. Montgomery, Superintendent) 



Extensive improvements to the buildings, grounds, and water supply were 

 made during the year. A .sluiceway was constructed in Craig Brook to handle 

 the brook flow, and a flume was built to conduct water from the intake tank 

 at the brook for the south ponds. Four ponds in the above system that had 

 been out of service for a number of years were dug out and cement inlets 

 and outlets supplied. On the west side of this system flve similar ponds were 

 likewise put in usable condition. A dam across Craig Brook near the lower 

 hatchery was completed, and by the installation of racks and screens a race- 

 way capable of handling at least 50,000 fish was formed. Repairs were made 

 to the main cement supply dam, and the reservoir above this is now available 

 as a. rearing ix)nd. In addition to this and other work, which materially 

 Increased the station's capacity, the buildings were kept in good repair and 

 many minor improvements effected. 



Brook-trout eggs obtained from the station brood stock amounted to almost 

 1,500,000, and more than 1,100,000 of these hatched. All of these fish were 

 distributed at various ages, with the exception of 73.600 that are being held 

 over for distribution in the fall. A number of brook-trout eggs from commer- 

 cial sources and from exchanges also were handled, giving additional finger- 

 lings for distribution. The station opened the year with more than 250,000
