The distributions from the Grand Lake substation consisted of 

 47,880 brook-trout fry, 115,000 eyed egfjs of the hmdlocked salmon, 

 55,000 hindlocked-sahnon fry, and 79,100 landlocked-sahnon finger- 

 lings, -with approximately 74,000 fingerlings of that species on hand 

 at the end of the year. 



NASHUA (N. H.) STATION. 

 [Waldo F. IIubbakd, Superintendent.] 



The work at this station Avas concerned with the brook and rainbow 

 trouts, pike perch, and suialhnouth black bass. A few brook-trout 

 eggs were obtained from brood hsh at the station, but most of the 

 eggs of this species were acquired by purchase. The rainbow eggs, 

 with the exception of 16,638 taken from fish in the hatchery ponds, 

 were transferred from the Wytheville (Va.) station, and the pike- 

 perch operations consisted in the incubation of 2,000,000 eyed eggs 

 shipped from Swanton, Vt. During the spawning season of the 

 smallmouth black bass in Lake Sunapee, extending from June 2 to 

 June 17, collections of fry of that species to the number of 31,700 

 were made and shipped to applicants. The work with the various 

 species was conducted without unusual incident, and the output of 

 fish for distribution is shown in the table on page 12. 



ST. JOHNSBURY (VT.) STATION. 

 [A. II. DiNSMOKE, Superintendent.] 



From this station as a center the usual field stations for the collec- 

 tion of brook-trout eggs were operated at Lake Mitchell and Darling 

 Pond. Largely because of climatic conditions, the results of the 

 w'ork at both points were rather unsatisfactory. The e<i<^ collec- 

 tions amounted to 214,148 and 411,777, respectively, all of which 

 were of the usual high quality. 



During the summer of 1920 an investigation was made of the 

 fish-cultural possibilities existing at points on the Big Margalloway 

 and Little Margalloway Rivers and Parmacheence Lake, in northern 

 Maine. As the field gave promise of satisfactory returns, a tentative 

 plan was formulated for undertaking work in cooperation with the 

 Northern Oxford Guides Association. The first eggs were taken 

 October 13, and the collections, which extended to October 27, aggre- 

 gated 300,000. As the main objects of the work were to build up the 

 supply of trout in the local waters and to encourage the local or- 

 ganization in their fish-cultural activities, the bureau claimed only 

 50.000 of the eggs secured. The others were successfully incubated 

 in the log hatchery put up by the association, and the resulting fry 

 were ])lanted, with but slight loss, in local waters. While the work 

 was not particularly successful from a fish-cultural standpoint, the 

 information gained will be useful in connection with any future work 

 that may be attempted in that field. 



At Lake Dunmore, Vt., a new field station was established for the 

 collection of lake-trout eggs and was operated jointly by Federal 

 and State employees. Eggs to the niunber of 130,000 were collected 

 and sent to the Holden hatchery, another subsidiary of the St. Johns- 

 bury station, to be eyed. After reaching the eyed stage half of 

 them were turned over to the State fisheries authorities.
