The economic aspects of small-scale fisheries production and marketing operations in San Miguel Bay, Philippines, and the distribution of total catch and revenues among major gear types are addressed in this report, consisting of 9 separate papers, each viewing the topic from a different angle. The initial paper describes the objectives, methodology, and major findings of an economic survey of San Miguel Bay fisheries operations. Provided next is an analysis of the costs and returns of employing gill-netters, the major small-scale fishing gear; sharing arrangements between owner and crew are also discussed. Similarly, succeeding papers examine the costs of and earnings from stationery gears and push nets at a specific Bay site, Cabusao. The costs and earnings of employing mini-, small, and medium-sized trawlers are assessed next. Subsequent papers discuss the institutional and technical aspects of access to fishery resources, and the pricing efficiency and related economic aspects of fish processing and marketing in 2 Bay communities. A final paper investigates the economic efficiency and distribution of benefits within Bay fisheries, showing that small trawlers, which represent only 3% of the fishing units and employ 7% of the labor, earn the largest share of total catch value and 50% of profits; policy implications are discussed.
