REPORT OF COMMISSIONER OF FISH AND FISHERIES. 107 
'Josses occurred amounting to 139,000, and as a result distribution was 
‘commenced, 340,000 being liberated in that month. The mortality 
‘continued, and during August 100,000 additional fish were liberated, 
‘completing the distribution. 
Lake trout.—On October 1 preparations were commenced looking to 
‘the collection of lake-trout eggs at Isle Royale. This island, in the 
|northwestern portion of Lake Superior, is an uninhabited wilderness 
‘of jagged rocks and tangled thickets, containing neither trails, paths, 
nor roads, and visited by one steamer only, whose service is irregular. 
‘At Grand Portage a few eggs were obtained from fish caught in pound 
‘nets, all others being from gill-net captures. The weather was exceed- 
ingly stormy, and the quality of eggs poor. The firsteggs were received 
‘at the station October 4, packed in boxes. Other shipments followed 
‘throughout this month and in November, the spawn-takers returning 
‘November 19. Low air temperature destroyed a number of eggs in 
‘shipment and the shrinkage was great. Measured on December 13, the 
‘total number was found to be 1,527,000. The first hatching occurred 
21st December, 10,000 having come out from the eggs by the end of 
‘the month, the last hatching occurring May 16. Fry were liberated in 
sixteen lots, March 8 to April 10, aggregating 850,000, there being left on 
hand April 15, 400,000 eggs and 695,000 fry. Losses in May amounted 
to 5,000, and in June to 15,000. There being a mortality of 6,000 on 
June 19, gravity water was discontinued, the pumps supplying water 
from the lake. Distribution during the month amounted to 1,075,000, - 
‘deposited near the shores of Michigan and Minnesota, the total libera- 
tion during the year being 2,365,000. 
Whitefish.—There were collected by station employees in the fall 
750,000 eggs of whitefish, the number on hand December 13 being esti- 
mated at 500,000. This number being insufficient for stocking waters 
of that region, eggs were assigned from Alpena and Put-in Bay stations, 
6,000,000 being received from the former, with a transportation loss of 
18,000, February 24, and 5,000,000 from the latter station, with a loss 
of 300,000, March 1. Between April 1 and 10 four lots of fry Liberated in 
the vicinity amounted to 145,000, leaving 10,382,000 eggs and 100,000 
fry on hand April 15. During April 300,000 fry were liberated, and in 
May 10, 182,000, of which 2,982,000 were put out in the vicinity of the 
station, 6,000,000 near the shores of Wisconsin, 1,500,000 near the shores 
of Michigan, the last eggs hatching May 24. In December, 1892, young 
whitefish appearing in the vicinity of the station (an unusual occur- 
rence), Specimens were sent to Washington for identification. 
Rainbow trout.—The Neosho Station being overrun with rainbow- 
trout eggs, two consignments were made to the Duluth Station, 75,000 
being received February 11 and 25,000 February 15. The losses from 
date of receipt to April 15 amounted to 5,000, leaving on hand 20,000 
eges and 70,000 young. There were lost subsequently, 750 in April, 
6,000 in May, and 250 in June, the last hatching occurring May 21. The 
distribution of 83,000 occurred in June, 43,000 being placed in the St.
