REPORT OF COMMISSIONER OF FISPI AND FISHERIES. XXI 



of the year there remained on hand 131,141 landlocked salmon, 1G,220 

 Atlantic salmon, and 9,335 steelhead tront. 



Having- decided to discontinue the distribution of Von Behr trout, 

 the 769 brood fish on hand in the fall were turned over to the fish com- 

 missions of Maine and Vermont. While the flume was being prepared 

 during' the summer it was found impracticable to provide ponds for the 

 landlocked salmon that had been reared at the station, and, in view of 

 the fact that they were about 6 years old and had never produced 

 healthy eggs, it was determined to liberate them in Green Lake. There 

 were 2,164 of these fish, varying from 1 to 3 pounds when liberated. 



Craig Brook Station, Maine (Charles G. Atkins, Superintendent). 



During- the year two large, deep ponds were constructed on the flat 

 alongside Alamoosook Lake for the purpose of continuing the experi- 

 ment of roaring Atlantic salmon under domestication and for domesti- 

 cating such species as the steelhead trout, landlocked salmon, and 

 quinnat salmon. These i}onds are each about 3,750 feet in area, and 

 the expense of building them was ^619. In addition to a number of 

 minor improvements to the buildings and grounds, the old wagon-house 

 was moved and repaired, a stone bridge was built across the brook, two 

 gravel breakwaters were constructed to protect the boat-landing, the 

 fly-house was transformed into a hatchery for the purpose of caring- for 

 the quinnat-salmon eggs transferred from the Pacific Coast, and a new 

 stand of troughs was erected for holding the fry. An aqueduct 700 

 feet long was also constructed in order to convey the water supply from 

 Craig Brook to the above-mentioned stands and hatchery. 



At the beginning of the year there were on hand the following fry, 

 hatched the previous spring: 



Atlautic salmon 244, 405 



Landlocked sjilinou 11, 033 



Quinuat salmon 7, 796 



Brook trout 2,668 



Rainbow trout 12, 778 



American lake trout 38, 965 



Swiss lake trout 46, 796 



Von Behr trout 487 



Scotch sea trout 1, 337 



Steelhead trout 12, 511 



Total 378, 776 



During July 3,315 steelheads were liberated; the remainder of the 

 stock was carried through to October, when the fish were counted and 

 distributed with comparatively small losses The food given was the 

 same material usually employed — chopped liver and other butchers' 

 offal, the flesh of horses, and maggots reared at the station. A small 

 (piautity of herring roe was also used and appeared to be acceptable 

 to the quinnats, though it was not readily taken by the Atlantic salmon. 

 As in former years the food most readily eaten was the maggots, which 

 were given alive. This year for the first time a large number of fry 

 were kept in the ponds, and although the losses were slightly heavier 

 than heretofore, these fry did remarkably well and outgrew the trough 

 fish. In all, 10i',265 Atlantic salmon and 8,122 steelhead trout were 

 transferred to the ponds; three mouths later 91,017 Atlantic salmoji 

 and 7,398 steelheads were removed, showing a loss of 11 per cent on the
