indicated a ratio of six chubs to one trout in shallow water and two 

 to one in deeper water, While studies made by Hays indicate no signifi- 

 cant competition for food between trout and chubs, chubs certainly com- 

 pete with trout for space,, 



Recent management of the Madison River fishery has consisted 

 of stocking and enforcement of fishing regulations. 



Legal-sized fish s mostly rainbow and brown trout, have been 

 stocked almost exclusively during the past 10 years. Most of these fish 

 have been provided by the U. S. Fish Cultural Station located near Ennis, 

 with some being supplied by the U„ S„ Fish Cultural Station at 3ozeman 



State fishing regulations in force during the study specified 

 a creel limit of 15 fish, including not more than 5 fish under 7 inches 

 in length, or 10 pounds and 1 fish for the river and Madison Reservoir,, 

 The creel limit on Hebgen Reservoir was 5 fish not to exceed 10 pounds 

 and 1 fish„ Seasons are shown in Table 1 by year and area affected.
