FOREST, FISH AND GAME COMMISSIONER. 22g 



No. 64 and 76 of the Department of Agriculture, describing the studies 

 of Messrs. George T. Moore and Karl F. Kellerman. 



It is recorded that a ratio of one part of blue vitriol, or copper sul- 

 phate, to one million parts of water will not injure black bass eggs or fry, 

 but it has proved fatal to brook trout even in a weaker solution. 



Courtesies 



Plans of black bass stations have been furnished by the U. S. Fish- 

 eries Bureau for consultation in establishing a pond station at Constantia. 

 The Commission is indebted to that bureau also for a set of blank forms 

 used in its hatcheries, for 170,000 brook trout fry, reared at the Cape Vin- 

 cent station, 5,000,000 eggs of pike perch from the same establishment, 

 4.250,000 lake trout eggs, forwarded from Northville, Mich., and 5,000,000 

 eved whiterish eggs. From the New York Aquarium 8,000 lake trout fry 

 were obtained in May, 1906, and were planted in Lake Ronkonkoma. 

 Twenty-five thousand whitefish fry and pike perch were presented by the 

 aquarium for State waters. The Southside Sportmen's Club, of Long Island, 

 through its president, Mr. George P. Slade, offered to aid Foreman Walters 

 in collecting smelt eggs at Great River. On account of repairs in progress 

 in the river the customary spawning run of smelt did not enter, but every 

 effort was made by the club employees to help our work. 



The Commissioner of Fisheries of Pennsylvania, Mr. W. E. Meehan, 

 was allotted 5,000,000 smelt eggs and 1,000 smelt from the Cold Spring 

 Harbor Station in exchange for brook trout and rainbow trout. Late in 

 the year, Commissioner Meehan was granted permission to collect the eggs of 

 lake trout on Trout Reef, near Dunkirk, with a view to restocking Lake Erie. 



An exchange was made with the Wyandanch Club, of Smithtown, L. I., 

 of 6,000 rainbow trout fingerlings, reared at Caledonia, for an equal number 

 of brook trout from the club's preserves. The brook trout thus secured 

 were planted in streams on Long Island.
