REPORT OF COMMISSIONER OF FISH AND FISHERIES. 



During May and June, 1902, the angler.s reported an average of 

 about 200 pounds a day from this lake, and the largest fish, which 

 undoubtedly resulted from the plant in 1897, weighed 5^ pounds. 



The stock on hand at the close of the year is shown by the following 

 table: 



Nashua Station, New Hampshire (W. F. Hubbard, Superintendent). 



Besides the brood stock of lish on hand at the beginning of the year, 

 there were 63,810 brook-trout fry which were reared to yearlings 

 before being distributed, the product of the same amounting to 62,500 

 yearlings. There were also on hand at this time 46,100 landlocked- 

 salmon fry hatched from eggs belonging to the New Hampshire Fish 

 Commission on shares. The product of these fish amounted to 22,400 

 yearlings, one-half of which were turned over to the New Hampshire 

 Commission and the balance distributed in the usual manner. 



During the summer a disease known as pop-eye attacked the 55 

 adult rainbow trout retained as a brood stock. The eyes protruded 

 from the head, and little bubbles, some of them as large as peas, 

 appeared on the gill-covers, fins, and other parts of the body. When 

 the disease made its appearance the fish were being held in one of the 

 rearing-ponds 100 by 8 feet in dimensions and with plank sides and 

 bottom. In order to cure the affection, the fish Avere transferred to a 

 larger pond, 150 by 100 feet in area, with natural earth embank- 

 ments, and as a consequence only two of them died. When removed 

 from this pond, in November, they were found to be in good condition 

 and produced eggs during the following spawning season. 



In the course of the summer the superintendent visited various 

 places in the State with the view to finding suitable locations for field 

 stations, and as a result a station for the collection of brook-trout eggs 

 was, in September, established at the Balsams, 12 miles east of Cole- 

 brook, the nearest railroad station. Another station was established 

 at Lake Sunapee for the collection of eggs of the brook trout, golden 

 trout, and landlocked salmon. 



At the Balsams the fish were caught by means of a trap, in a brook 

 tril)utary to the pond, and held in pens. The eggs were transferred 

 daily by wagon 12 miles to the State hatchery at Colebrook, where 

 they were eyed, and in December shipped to the Nashua Station.
