model should incorporate the 14 squares includ- 

 ing independent measures of the size of the 

 stocks and of recruitment and the feedback 

 from the economic side. 



It is often said in international fishery dis- 

 cussions that no regulation should be adopted 

 or even proposed before it can be justified by 

 sufficient "scientific evidence." Nobody is fooled 

 any more by this sophisticated expression which 

 means that national economic short term 

 interests should prevail as long as there is no 

 definite proof that such national interests are 

 leading to detrimental international economic 

 consequences. It is obvious that such scientific 

 evidence has often been supplied by the 



biologists, if only when they stated that numer- 

 ous stocks are exploited beyond the point of 

 MSY. But the precise economic consequences 

 of these statements are very rarely available; 

 and there is practically no case where the 

 economic consequences of the cuts to be made in 

 the fishing effort have been evaluated (short 

 term costs or losses and long term benefits 

 according to the possible regulations to be 

 adopted). It is obvious that such "practical" 

 evidence will never be supplied without a close 

 cooperation between biologists and economists. 

 The possibility of successful fishery management 

 is entirely dependent on such bioeconomic 

 research work.
