trieves the net and removes the fish from 
the net. 
Hoop nets of 1-, 214-, and 3-inch mesh 
were used in the survey. The 3-inch- 
mesh nets were fished only at the Du- 
buque station. 
The wing net, fig. 9, is identical in con- 
struction to the hoop net insofar as the net 
proper is concerned. Attached to the first 
hoop of the wing net are two pieces of 
netting called wings, which give the net 
its name. The wings are set at about 45 
degree angles to the main axis of the net 
and are secured in position with poles. 
The wing net is fished either with or with- 
out a lead, a piece of netting extending 
outward from the first hoop and continu- 
ing the main axis of the net. It is fished 
in sloughs, backwaters, and sluggish sec- 
tions of rivers; also in shallower water 
than the hoop net. It is held in position 
by poles. On the Illinois River, the wing 
net is the net most commonly used by 
fishermen, whereas on the Mississippi the 
hoop net is the one most generally fished. —
