Despite the complexities, it is an area which may have to be addressed. 

 In international trade negotiations for example, offsetting tariff schedules 

 can be invoked where foreign subsidization can be shown. This issue has 

 arisen in the past but the existence and levels of foreign subsidies must 

 be established to invoke such tariffs. 



D. 2. Recreational Fisheries 



Sections 2(b)(3), Section 3(2) and Section 3(18) express Congressional 

 purpose or intent with respect to recreational fisheries. Although the Act

 recreational opportunities. Section 3(18) defines OSY so as to provide 

 "the greatest overall benefit to the Nation with particular reference to

 recreational benefits; a subset of which deals with recreational fishing 

 benefits. In general there are substantial conceptual gaps in measurement 

 techniques which need exploration before one can devise a rational, compre- 

 hensive economic data collection system for recreational fisheries. 



E. Species and Fisheries Most Likely Affected by the Act 

 E.l. Species 



The resources most immediately affected by the Act may be classified 

 by species or type of gear and vessel used for its harvest. The species 

 or species group classification is most relevant for biological data collec- 

 tion and research. Appendix Tables A. 1 and A. 2 list the species which are 

 likely candidates for management plans under the New England and Pacific 

 Councils, respectively. These species are candidates at least for pre- 

 liminary management plans under Section 201(g) of the Act. It is assumed
