Provides a study of opportunities for Title XII collaborative research between the U.S. and developing countries in the areas of fisheries and aquaculture and proposes a plan for such research. Potential collaborators are identified through inventories of U.S. universities and of universities and other institutions in Africa, Asia, South America, the South Pacific, and the West Indies. U.S. universities are listed in 3 broad categories on the basis of overall capability. Specific developing country institutions are recommended for participation in collaborative programs. Developing country research needs in fisheries and aquaculture are analyzed and lists of research needs (as distinct from training, technical assistance and other needs) are provided. The sources of information in this section of the report are interviews with governmental and other key personnel in developing countries and a country-by-country literature review. Priority research areas are identified on the basis of the following criteria: size of target group; geographical area; the perceived needs of developing countries; time required to conduct research; cost; probability of research success and of application of research results; research capability and preparedness of U.S. and developing country institutions. A five-year plan of 9 priority programs embracing 16 specific areas within the general areas of capture fisheries, aquaculture, and product utilization is proposed as follows: (1) principles and mechanisms of pond culture systems; (2) resource assessment, feed and nutritional requirements, seed availability, causes and rates of spoilage of catch in tropical waters; (3) new or expanded fisheries; (4) fisheries administration and the extended economic zone; (5) control of spoilage in fisheries products; (6) environmental analysis and habitat protection; (7) culture systems for native species, morbidity causes and controls, new product and processing technique development; (8) low-energy preservation and processing techniques; (9) genetic improvement. A bibliography of nearly 600 titles on fisheries and aquaculture issues is provided. Appended also are a glossary of key report terms; common acronyms of U.S. and developing country institutions involved in fisheries and aquaculture; and a directory of international development organizations active in developing countries.
