18 REPORT OF COMMISSIONER OF FISH AND FISHERIES. 
The heaviest losses having occurred among the species derived from 
eggs received from a distance, viz, the rainbow and brook trout, it is 
inferred that packing and transportation were factors in the greater 
mortalities shown, especially since the smallest loss occurred among 
the Atlantic salmon, which were produced from eggs taken at the 
station. 
When liberated, the Atlantic salmon were deposited in neighboring 
brooks. The landlocked salmon, with the exception of a few hundred, 
were taken across the country and placed in Green Lake. Of the113,159 
reared fish, 14,139 were still further retained for winter feeding, among 
them some of each kind and age. These were placed in special tanks, 
with the exception of a few which were kept in the open-air troughs 
till late in the winter. The mortality during this period was small. 
1890-91. 
The collection of Atlantic salmon eggs was conducted with the codp- 
eration of the States of Maine and Massachusetts. It having been de- 
termined to devote more attention to the rearing feature, it was decided 
to reduce the egg-collecting to a scale commensurate with the capacity 
of the station, but a smaller number of eggs was obtained than was 
desired, owing to the scarcity of adult salmon, only 133 being secured. 
At the spawning time, October 1890, 77 of these remained alive in the 
inclosures, of which 52 were females, yielding 553,400 eggs. The good 
eggs remaining in January were divided, Maine receiving 264,000, 
Massachusetts 153,000, and the United States 134,218. The share of 
the United States was increased by the Maine commissioners, who con- 
tributed 183,000 for purposes of hatching and rearing. 
In addition to the salmon eggs, there were also produced 23,146 of 
the brook trout from fish artificially reared. These and other eggs re- 
ceived at the station are noted in the list below:

Both the Von Behr and Loch Leven trout eggs arrived in poor con- 
dition, having already commenced hatching, and gave practically no 
results. AJl other eggs were good, and the epidemic usually incident 
to the months of May and June of former years did not occur. About 
150,000 fish of the hatching of 1890 were cared for in rearing troughs 
till the present fiscal year, all being liberated in October, 1890, except
