TECHNICAL MANUAL FOR RESOURCE ENHANCEMENT
MetadataShow full item record
In the last two decades, many countries throughout the world have declared their own Exclusive Economic zones (EEZ), of which there are now two hundred. However, in the case of neighbouring countries, many of them have not yet reached agreement on the extent of their territorial waters. On the other hand, on a more general level, the situation with regard to fishing gear and fishing technology has improved considerably. Nevertheless, this modernization has in turn, brought about a rapid decline in marine resources, due to both the increase and the greater efficiency in fishing activities. As a result, the den and for more advanced technology in order to enhance marine resources has grown rapidly in those regions where the EEz situation is still unresolved. As a contribution to this resource enhancement, therefore, SEAFDEC is issuing a technical manual which is concerned with artificial reefs, in particular. The author, who has been working with SEAFDEC for two years, feels that there is still a lack of knowledge of tropical marine ecology. For instance, major additions to the marine forest in the Southeast Asian region are recommended, as part of the new technology. At first it was considered whether it would be better to reconstruct coral reefs, instead of introducing more marine forest; and, given the importance of the vegetable kingdom in the environment, it was decided that the latter should be recommended. Both artificial reefs and additions to the marine forest are, therefore recommendations made in the manual. It is hoped, first of all, that this manual will be made available to the many officers, who are in charge of artificial reef projects in the SEAFDEC member-countries, and that it will reinforce the work which is being carried out.
