PROPAGATION AND DISTRIBUTION OF FOOD FISHES, 1921, 81 
The work began at Prescott, Wis., on August 12 and was brought 
to a close at Bellevue, lowa, on Novy ember 10, these dates indicating 
an unusually short season on account of the natural conditions men- 
tioned. The work was conducted. in the following fields: 
One crew, with house boat, from Prescott, Wis., to Red Wing, Minn.; thence 
to Genoa, Wis. 
Two crews on house boats from Wabash to Winona, Minn.; thence to Dakota 
and Dressback, Minn. 
Two crews from Homer, Minn. 
One crew from La Crosse, Wis. 
One crew from Genoa, Wis. 
One crew from Ferryville, Wis. 
Two crews from Lynxville, Wis. 
One crew from Marquette, Towa, 
One crew with house boat from Dubuque to Bellevue, Towa. 
One crew from Bellevue, Lowa. 
In addition to the regular rescue work collections of eggs Soin 
earp and buffalofish taken by commercial fishermen were “made at 
Bellevue and Lynxville. The eggs were taken, fertilized, and planted 
on the natural spawning erounds. Such work was done from May 9 
to 25 and resulted in the fertilization of 68,287,000 buffalofish and 
42,718,000 carp eggs. Had these eges not been thus handled they 
would have been sent to the markets in the fish and lost. While the 
planting of fertilized eggs is not considered as efficient as incubating 
them in a well-equipped hatchery, it is believed that under certain 
conditions it is expedient and results in much good if properly done. 
In addition to the operations on the upper Mississippi rescue work 
was conducted from the Fairport (Iowa) biological station; also on 
the Illinois River at Meredosia and Cairo, IIl., and at San Mareos, 
Tex. The operations from Fairport and ‘substations were in con- 
junction with the propagation of the fresh-water mussel, large num- 
bers of the rescued fish being inoculated with the mussel elochidia 
before being liberated. Owing to unfavorable water stages the active 
season at Cairo was very short, extending cnly from October 1 to 19. 
In this field one seining crew wor king under the direction of the 
superintendent of the Louisville (Ky.) station salvaged a total of 
1,057,215 fish of miscellaneous species at a total cost “of $582 OT, or 
at the rate of 55 cents per thousand fish handled. In the vicinity of 
the San Marcos (Tex.) station 202,886 black bass, catfish, and sunfish 
were removed from the bed of a stream, which almost entir ely 
evaporated during a protracted hot spell, and were deposited in 
living waters. Reference to the table on page 7 will show the points 
from which rescue work was prosecuted during the season, the num- 
ber of fishes salvaged at each and restored to the original waters, 
and the number delivered to applicants.
