Reference has been made previously to the fact that artificial ponds 
are used to produce fish within the refuge in addition to the large 
quantities obtained in rescue work. Construction work on several of 
these ponds continued throughout the year and they have demon- 
strated a high rate of productivity which promises a highly valuable 
yield of game fish when rescue work is discontinued, as it will be 
shortly, due to canalization of the river. 
It will be noted that crappie and sunfish were most abundant among 
the fish rescued from the landlocked overflow pools of the Mississippi, 
and bass were comparatively scarce.

ASSIGNMENTS OF FISH AND FISH EGGS TO STATES, TERRITORIES, 
AND FOREIGN COUNTRIES 
There were 162,801,475 fish and eggs assigned to the various States, 
either by direct delivery or by distribution to the credit of the State. 
The differential in comparison with the 639,000,000 listed under the 
same category last year is due to the fact that the production of pike- 
perch at the Put-in-Bay, Ohio, station is no longer listed as an assign- 
ment to the State. This hatchery is now operated on a joint basis 
with the Division of Fish and Game of the State of Ohio and its output 
of pike perch, totaling, on an average, around 500,000,000, cannot be 
considered as a direct contribution of the Federal Government. 
Thirty-nine States shared in the production of the Federal hatch- 
eries, in comparison with 32 in the previous year. Approximately 
half of these assignments consisted of eggs, principally of the various 
species of trout. In many instances the capacity of the Federal 
hatcheries is insufficient to take care of all of the trout eggs secured, in 
which case the logical procedure is to transfer them to State hatch- 
eries. In some sections, particularly in Indiana, where the available 
mileage of trout waters is limited, the State is relieved of the necessity 
of propagating trout through arrangements whereby they may be 
obtained from Federal hatcheries located in other States. A new
