In our tabulations, we based the economic value of commercial fish on the actual 
poundage taken from those lakes for which records were available, Table 5 shows that an aver- 
age catch of 141 pounds per acre-year was seined from the waters of four typical Illinois River 
bottomland lakes, This amounted to an average of $9.65 per acre each year at prices prevail- 
ing, 1943-1947, table 6. 
No seining of fish has been permitted at the Chautauqua National Wildlife Refuge, but 
commercial fishermen were permitted to take rough fish in hoopnets on about 60 per cent of the
