PROPAGATION AND DISTRIBUTION OF FOOD FISHES, 1940 599 
nurseries in Wisconsin, Minnesota, and Illinois are supervised. In 
Minnesota there was a total of 12 cooperative ponds with 8 sponsoring 
units, and in Wisconsin a total of 44 ponds, representing 29 separate 
agencies. A high percentage of fish delivered to each agency in the 
spring are planted each fall. Both the Northside station at La Crosse 
and the auxiliary unit at Lynxville were used during the spring to 
relieve congested conditions at the La Crosse hatchery. The hatchery 
pond at La Crosse produced 162,390 fingerling largemouth black bass 
(37,188 per acre). 
Because of a cold wave following warm spawning weather, the year’s 
production of largemouth black bass eggs in pond No. 1 (about 35 
acres in area) at the Genoa (Wis.) station was practically a total loss. 
Consequently, only a few early deliveries of fingerlings were made. 
Fry produced in other ponds were transferred to pond No. 1 for rearing 
and subsequent distribution. Three additional ponds with a total 
area of approximately 12 acres were stocked with smallmouth black 
bass, one 4-acre pond was stocked with sunfish, and another pond 
with crappie. Three new ponds having an area of approximately four 
acres each were constructed during the year. They complete the 
system of ponds north of the Bad Axe River. Extensive changes were 
made in two older ponds. 
The personnel of the Homer (Minn.) unit was engaged in general 
repair work for all stations in the central district. Portable equip- 
ment such as nets, seines, rowboats, small engines and motors, and 
standard forms for concrete and cement work were constructed or 
repaired. Both efficiency and economy result from such a practice 
when the work is sufficient to require full-time service of the mechanics, 
as is now the case.

AQUARIUM 
While no major changes in equipment or operations were eflected 
in the Aquarium during the year, the periodical acquisition of new 
specimens stimulated a continuing public interest in the displays. 
As usual most of the exhibit fishes were obtained from the Bureau’s
