be calculated by simple division. A small number of economic studies exist 

 (Table 9) which together with the above price data, constitute the existing 

 economic data base. The basis for inclusion in the list is a significant 

 contribution to an economic data base. Other studies exist which emphasize 

 conceptual economic aspects of fisheries management. These have not been 

 included in the above list. It is very important to recognize that even the 

 studies which are listed in Table 9 may be deficient when viewed as part of 

 a data base. They are by their nature unique or ad hoc studies. The 

 retrievability and validity of the raw data on which the studies are based 

 can be expected to decay over time because continuity is lacking and the 

 institutional context of these studies generally favors research but is not 

 favorable to maintaining continuing data bases. Because they are not 

 current, most of the regional studies which have been done are of limited 

 use to Councils. State (i.e., non-university) supported studies relating 

 to economic data collection were found to be unknown to persons inter- 

 viewed in both the New England and Pacific Regions.
