whereby that agency will assign C. C. C. labor for the construction 

 of a number of rearing ponds on the station property. These will be 

 used to rear fish exclusively for the waters of the Acadia National 

 Park. It is expected that a number of other improvements will be 

 effected in connection with this program. 



The Nashua, N. H., station was subjected to the ravages of the 

 spring floods which virtually wiped out the supply of trout fingerlings 

 on hand. The entire hatchery reservation was flooded and while a 

 few fish were salvaged it was necessary to ship in brook trout fry 

 from other hatcheries in order to secure a greatly reduced output of 

 fish for distribution. 



The St. Johnsbury, Vt., and York Pond, N. H., stations were sep- 

 arated administratively, the former being now independent of the 

 field operations at York Pond. At St. Johnsbury unusually good 

 results were obtained in the rearing of landlocked salmon from eggs 

 supplied by the State; 65,000 yearlings were produced, some of them 

 reaching 9 inches in length. The output of brook trout was cur- 

 tailed due to the poor quality of the eggs transferred from York Pond. 

 Considerable improvements were attempted by W. P. A. allotment. 

 The foundations of several of the buildings were repaired, painting 

 was done, and the drain line to the ponds was renewed. A new heat- 

 ing plant was installed in the hatchery building. 



At York Pond there was a combination of imfavorable circumstances 

 which caused a heavy loss of brook trout brood stock, followed by 

 an outbreak of the "soft egg" disease, which makes sporadic appear- 

 ance, particularly in the New England hatcheries. In consequence 

 the output of fry and fingerlings at this station was below normal 

 and shipments of eggs to other hatcheries produced very unsatisfactory 

 results. The development program continued by virtue of C. C. C. 

 labor and a W. P. A. project. The pond system has been improved 

 and a new well furnishing 100 gallons per minute was developed. 

 The water supply canal to the power-house has been virtually rebuilt. 

 A large ice storage building was constructed, and numerous minor 

 improvements all contributing to the efficiency of the plant have 

 been completed. Experiments in determining cheaper fish foods 

 presented some interesting information but no definite conclusions 

 have been reached as yet. 



At the Harts^alle, Mass., station operations were of a routine nature 

 with the exception that unusually favorable results were obtained in 

 the collection of smallmouth bass fry in Connecticut, in cooperation 

 with the State Board of Fisheries and Game. Over 840,000 fry were 

 handled. The collection of brook trout eggs from station stock 

 amounted to over 400,000 and a considerable number of excellent 

 fingerlings, ranging up to 6 inches in length, were placed in local 

 waters. No significant improvements or expansions could be carried 

 on during the year. 



COMBINATION TROUT AND POND-FISH STATIONS 



Most of the establishments in this category are primarily concerned 

 with the propagation of trout, and the production of warm water 

 pond fish is a sicle line or by-product. At the Manchester, Iowa, sta- 

 tion the year's operations were of normal extent. The station brood 

 stock yielded over 2,000,000 rainbow trout eggs and the eggs of other 

 species shipped in produced a quantity of fingerlings adequate for all
