82 Thirty-ninth Annual Meeting 



since 1894 has been al)out 1,500 per cent. In Minnesota and 

 Wisconsin the increase has been from 6,863 pounds in 1894 

 to 228,690 in 1899, and to 3,379,400 in 1908, or 49,000 per 

 cent more than in the year first named. 



The increase in abundance of carp has not unfavorably 

 affected the yield of the more valuable species, as appears 

 from the returns of the' present census. For instance, the 

 yield of black bass in Illinois shows an increase from 96,829 

 pounds in 1894, to 126,180 in 1889, and to 502,300 pounds 

 in 1908, or more than five times as much as in 1894. In 

 those States bordering the Missouri River, the yield of this 

 species shows an increase from 195,867 pounds in 1894 to 

 413,100 in 1908. In Tennessee and Kentucky blass bass 

 have increased from 98,195 pounds in 1894 to 184,200 

 pounds in the census year. 



A similar condition exists in the yield of crappie. Illinois 

 shows an increase in this species from 168,280 pounds in 

 1894 to 356,320 in 1899 and to 1,260,560 pounds in 1908. 

 In the States bordering the lower Mississippi there appears 

 an increase from 298,500 pounds in 1894 to 486,000 pounds 

 in 1899 and to 684,000 pounds in 1908. In those States 

 bordering the Missouri River the yield of crappie has in- 

 creased from 180,200 pounds in 1894 to 471,000 in 1908. 



A similar comparison might be made for bream or sunfish. 

 which shows a corresponding increase; the combined yield in 

 Missouri, Tennessee, Arkansas, and Iowa amounting to 

 155,000 pounds in 1894, 325,000 in 1899, and 954,000 in 

 1908, or six times as much as in the year first named. 



Probably more interesting to the fish culturist of the Great 

 Lakes is the very large increase in the yield of whitefish. 

 especially in Lake Erie, where the results of the hatching 

 operations are especially striking. The catch of the fleet of 

 vessels at Erie, Pennsylvania, for instance, shows an increase 

 from 53.276 pounds in 1903 to 451.200 pounds in 1908. or 

 nearly nine times as rtnich. The increase of whitefish in Ohio 



-g( 

 respondingly as jn Pennsylvania.
