THE CREATION OF A MAN-MADE LAKE LED TO THE NATURAL DEVELOPMENT OF AN INLAND FISHERY AND SOCIOECONOMIC CHANGES AMONG THE FISHERMAN INVOLVED. THE ANALYSIS OF THESE CHANGES OF RESERVOIR MANAGEMENT ENCOMPASSES THE QUESTION OF OPTIMUM RATIO OF THE NUMBER OF FISHERMEN PER GIVEN AREA OF WATER SURFACE. THE ASPECTS OF FISHING OPERATIONS DISCUSSED IN THIS REPORT ARE: THE FISHERMEN'S SOCIOECONOMIC BACKGROUND, INCLUDING MIGRATION PATTERNS AND LOCAL GOVERNMENT; THE ECONOMICS OF THE INDUSTRY ITSELF; MARKETING FRESH WATER FISH LOCALLY AND THROUGH RETAILERS; AND A COMPARATIVE STUDY OF INCOME EARNED BY FISHERMEN, FISHMONGERS, AND WHOLESALERS. THE SURVEY OF 280 SAMPLE HOUSEHOLDS BORDERING THE RESERVOIR ALSO DETERMINED WHAT PROBLEMS IN THE OPERATION WERE SEEN BY THE FISHERMEN TO BE MOST SIGNIFICANT. REPORT RECOMMENDATIONS INCLUDE: 1. PLANNING AND SUPERVISING FISHING RESETTLEMENTS TO CONTROL THE NUMBER AND LOCATION OF FISHERMEN AROUND FUTURE RESERVOIRS, 2. STRENGTHENING THE BARGAINING POSITION OF FISHERMEN, PERHAPS VIA A FISH MARKETING COOPERATIVE, 3. CONTROLLING FISHING GEAR AND PRACTICES, AND 4. IMPROVING FISH LANDING AND MARKETING FACILITIES.
