This, we agreed, was necessary because of the distinctive and numerous specialized subjects that are dealt with in the papers included in these proceedings. We thought that any reader might benefit from a comparison of the past and present situation, and perhaps therefore obta in a better perspective on where or in which directions fishery research should be going. Several names of well known fishery scientists come to mind who might provide the critical, yet positive messages about what had or had not been done in the past, what needed attention now and perhaps directions to take in the future. To our surprise and satisfaction we found these kinds of messages clearly stated in an existing text. The following excerpts were even alre ady available under a chapter headed, “Review of the Present Position of Investigations”: “The study of methodically collected material, embracing a period of many years, has demonstrated the existence of an intimate relation between the fluctuations in the numerical value of the stock of fish and the yield of the great fisheries… -
Technical reportRapport de la Consultation d'experts chargés d'examiner les variations de l'abondance et de la composition spécifique des stocks néritiques. San José, Costa Rica, 18-29 avril 1983
Une réunion préparatoire pour le Conférence mondiale de la FAO pour l'aménagement et le développement des pêches.
1985L'étude des différents stocks néritiques comporte une assez grande marge d'incertitude. Il est difficile de fonder des politiques de développement national sur la base des données provenant d'un secteur halieutique instable. Des objectifs à long terme peuvent difficilement être atteints sans la mise au point d'une stratégie du développement qui tienne compte de cette instabilité. Pour permettre au secteur des pêches de s'adapter à ces fluctuati ons de la ressource il faut y introduire davantage de souplesse. Ces fluctuations et le processus écologique qui en est la cause doivent être suivis avec attention. Un certain nombre de problèmes et de solutions possibles concernant l'exploitation, la recherche et l'aménagement des pêcheries instables sont discutés.
