REPORT OF COMMISSIONER OF FISH AND FISHERIES. XXIII 



on August 27, making- a total of 33 captured by the trap. These were 

 placed in the cars and towed to Orland, whence they were transferred 

 to the Dead Brook inclosure, 20 of them being delivered alive. 



It appears that salmon do not congregate in large numbers at mid- 

 summer, and, moreover, it is very diflicult to transfer them at that 

 season to the inclosure, which is 30 miles distant, on account of the 

 high temperature of the water. To obtain good results, the trap 

 should be constructed early in the spring and a retaining pool pro- 

 vided in the immediate vicinity. 



During the summer 109 dead lish were removed from the pools, 

 which should have left o94 breeders, but as a matter of fact only 539 

 were found, indicating a loss of 25 per cent. Of these, 174 were 

 males and 3(35 females, 12 of which yielded no eggs. From the others, 

 the weight of which aggregated 1,050 pounds, 3,192,121 eggs were 

 secured, of which the Maine Commission received 496,000. From the 

 remainder, 490,000 were shipped as follows: To the New York Fish 

 Commission, 100,000; to the Connecticut Fish Commission,. 100,000; to 

 U. S. Fish Commission stations, 100,000; to W. S. Hadaway, Plymouth, 

 Mass., 25,000; to the Pennsylvania Fish Commission, 100,000; to the 

 Adirondack League Club, 25,000; to Amos Ellis, Rangeley, Me., 40,000. 



From the balance of the eggs 2,008,700 fry were hatched, all of which, 

 with the exception of 390,000, were liberated in the tributaries of the 

 Penobscot above Oldtown and in streams in the vicinity of the station; 

 150,000 were planted in the St. Croix River at Vanceboro, and 240,000 

 were retained for rearing. The loss on this stock to the close of the 

 year amounted to 24,442. At the beginning of the year there were on 

 hand 705 Atlantic salmon which had been hatched during the season 

 of 1893-94; of these^ 290 were distributed and the balance were placed 

 in one of the new ponds and retained for domestication. In June, 1897, 

 t4ie usual arrangements were made for the collection of adult salmon, 

 but owing to the late run only 595 were obtained. The losses during 

 June were very light, and favorable results are expected in the fall. 



From the two lots of domesticated salmon (descendants of parents 

 reared in confinement in fresh water) 4,400 eggs of inferior quality were 

 secured during November; these yielded 2,107 fry, but only 1,000 of 

 them survived to the close of the year. Of the parent fish there now 

 remain 41. 



Landlocked salmon. — Late in October 10,889 yearling landlocked sal- 

 mon were deposited in Toddy Pond. These fish resulted from a con- 

 signment of eggs delivered at the station by a number of citizens who 

 were interested in keeping up the supply of fish in that pond. In 

 November, 1890, the same parties furnished another consignment of 

 2,352, from which 2,129 fry were hatched. 



Other species. — The brook, rainbow, lake, and von Behr trout were 

 distributed with the other fishes in the fall, the losses being very 

 slight, except in the case of the lake trout. On July 1 there were 

 38,905 lake trout on hand, as a result of the eggs shipped from North-
