PRINCIPAL CREEL-CENSUS and EXPENDITURE DATA 



Fisherman use in terms of total fisherman days and fisherman days per 

 surface acre of reservoir (or lake) or per mile of stream, yield in terms of num- 

 bers and pounds of fish per hour, total number and poundage of fish, and pounds 

 of fish per surface acre or per mile of stream, and expenditures per person per 

 day, total for area, per pound of fish, and per surface acre or per mile of 

 stream, are shown for 26 areas studied in the Missouri River Basin between 19147 

 and 1952 in tables 1, 2, 3, and lj. 



Creel census data demonstrate tremendous variations in use and yield 

 of the many situations studied. These data for those areas studied more than 

 one year also demonstrate that there can be considerable variation in use and 

 yield from one year to the next on a particular area. A few of the more obvious 

 factors contributing to these variations, such as ease of access, nearness to 

 centers of population, and natural attractiveness of an area, are indicated in the 

 description of the areas, but it is impossible to make any generalization of 

 correlation. 



Examination of data shown in the accompanying tables indicates that 

 fisherman expenditures per day are generally higher for cold-water fishermen 

 than for warm-water fishermen. On the average, cold-water fishermen spend 

 roughly twice as much per day as warm-water fishermen. Two factors seem im- 

 portant: (1) Cold-water fishermen spend more for equipment, and (2) cold-water 

 fishermen are inclined to travel greater distances to fish and thus not only 

 have larger transportation expenses but also have more trip expenses. Other 

 expenditure figures shown in the tables, of course, are dependent upon the use 

 and yield of the particular fishery and thus vary accordingly.
