The selected framework is shown in Table 4 as a series of questions 

 that must be answered in the process of planning and performing enforce- 

 ment activities under the provisions of Public Law 94-265. The questions 

 remain general in that they can apply to any desired enforcement area 

 from the entire 200-nmi Fishery Management Zone to a small, localized 

 fishery area of particular importance. The questions are also general 

 in that they can be answered with respect to any desired strategy or 

 level of enforcement by simple and obvious modification. For example, 

 if it were desired to concentrate enforcement in a given area only on 

 Japanese vessels catching salmon with purse seines, the question "any 

 foreign fishing vessels?" becomes "any Japanese purse seiners?," and 

 the question "are they fishing?" becomes "are they purse seining for 

 salmon?." 



Table 4 

 CRUCIAL QUESTIONS FOR ENFORCEMENT

• Any fishing vessels? 



• Any foreign fishing vessels? . 



• Are they fishing? 



• Do they have a permit? 



• Is the vessel operating within the terms of the permit? 



In performing the survey, each selected remote sensing technology 

 (technique) was examined with respect to its potential to contribute to 

 answering each question in Table 4. In accordance with the assigned pur- 

 pose of the survey, the examination concentrated on the performance of 

 detection and classification functions, but whenever it appeared that a
