fishermen. These catches, therefore, cannot be reliably projected without 

 a knowledge of the cost and revenue relationships of the U.S. fleets. In 

 addition to the normal free-market forces which impinge on them, there are 

 various domestic and foreign policies which affect cost and revenue rela- 

 tionships. Among these are vessel construction subsidies, marketing pro- 

 grams, fisheries development policies and trade barriers to U.S. exports. 



(ii) Conditions of access for foreign vessels 



Section 204(b) specifies the terms under which foreign fleets may 

 fish in waters under U.S. jurisdiction, including mandatory information 

 which must be supplied by such fleets and a residual clause covering "any 

 other pertinent information and material which the Secretary may require." 



Foreign fleets employ harvest technologies which differ in varying 

 degrees from those employed by U.S. fishermen. Some of these differences 

 include vessel construction, vessel size, and gear characteristics. Given 

 the physical data collected for management purposes it may be possible to 

 measure technical efficiency by analysis of variances in catch per unit 

 effort. Indices of technical efficiency are, however, only one of the com- 

 ponents which affect cost and earnings. For economic analyses, data would 

 have to be compiled directly on major inputs and costs of foreign fleets. 

 If this information is collected, it should be reported in a form which 

 permits isolation of operating costs in transit to waters under U.S. juris- 

 diction vs. operating costs while in such waters. It should also include 

 information on capital construction costs and foreign subsidies. 



Economic information on foreign fleets is of importance where the 

 fish harvested affect international trade of U.S. importers or exporters. 

 On the import side fish may be caught in U.S. waters, processed in a
