REPORT OF COMMISSIONER OF FISH AND FISHERIES. ae 
The fingerling fish derived from the ponds comprised 810 black bass, 
4,427 rock bass, 6,931 carp, and 1,911 goldfish. A consignment of 75 
adult black-spotted trout was received June 9, 1890, from the Leadville 
Station. Owing to injuries received in transit, only twenty of them 
survived the heat of the first summer, but these were in good condition 
July 1, 1891. A shipment of 5,000 eggs of,this species arriving Julye 
29, 1890, from the same station, hatched immediately, about one-half of 
fio fry denis during the first week. The remainder were further re- 
duced in numbers by the escape of some from the ponds, but several 
hundred were preserved in good condition. 
There was the usual lack of success with brook trout. Twenty thou- 
sand eggs arriving from the Northville Station January 18, 1891, imme- 
diately hatched; 7,600 fry died in the troughs by March 1, and the 
remainder soon after perished in the ponds. 
Unfavorable results also attended the handling of Von Behr trout 
eges and fry. Of a consignment of: 20,000 eggs from the Northville 
Station, received February 2, 1891, many were found either hatched or 
dead on arrival. A second rane of 20,000 arrived in good con- 
dition February 20, 1891, but they underwent 20 per cent loss in hatech- 
ing, and the fry perished, though apparently healthy—a portion in the 
troughs and the remainder in the ponds subsequent to transfer, April 9. 
Muddy water during the hatching season and the presence of lime in 
the station water supply are supposed to have been the obstacles to 
successful operations with this species and the brook trout. 
SANDUSKY STATION, OHIO (HENRY DOUGLAS, SUPERINTENDENT). 
1889-90. 
The agreement with the Ohio State Fish Commission, under which 
the operation of its hatchery at Sandusky was conducted by this Com- 
mission, was renewed. 
Higgs of the whitefish and pike perch were obtained from islands in the 
western part of Lake Erie, and from Port Clinton and Toledo. Those 
of the whitefish were collected during the month of November, 1889, to 
the number of 62,100,000. Of these, 10,000,000 were shipped to the 
Pennsylvania hate sere at Krie; 6,000, 000 to the Wisconsin State fish 
commissioners; and 6,000,000 to Conical Station, Washington, D. C. 
The Paar were Hate ned at che station, producing 30,628 000, all of 
which were liberated in Lake Erie except 100 000, at to Warren, 
Ind., at the request of the Indiana State Fish Commission. 
Pike-perch operations covered the period between April 12 and 26, 
1890, during which 81,000,000 eggs were obtained. Of these the Penn- 
Sy heer hatchery at Erie was given a consignment of 18,000,900 and the 
New York Fish Commission 1,000,000. From the remainder, 36,200,000 
fry were produced and liberated the first week in May.
