increases of 1,019,000, 574,000, and 231,000 pounds, 

 respectively. These increases, together with those 

 of yellow perch and of certain minor species, ex- 

 ceeded by 796,000 pounds the decreases in the take 

 of whitefish (769,000 pounds), white and redhorse 

 suckers (149,000 pounds), lake trout (134,000 

 pounds), and other varieties. 



Pound nets, which took 3,157,000 pounds, or 

 36.8 percent of the total, were the most productive 

 gear in 1950 (table 25) . Next in importance were 



large-mesh gill nets (1,998,000 pounds, 23.3 per- 

 cent), small-mesh gill nets (1,996,000 pounds, 23.3 

 percent), and shallow trap nets (1,330,000 pounds, 

 15.5 percent). No other method of fishing con- 

 tributed as much as 1 percent of the total. 



The 1950 production of 8,578,000 pounds in 

 Green Bay constituted 70.2 percent of the State of 

 Michigan total of 12,223,000 pounds for Lake 

 Michigan. The corresponding percentage was 

 65.4 in 1949.
