ESM 204 Management of Fisheries in Costa Rica Background : The Government of Costa Rica is concerned about the health of one of its most important fisheries, in the Gulf of Nicoya on the Pacific side of the country. Your task . The Government of Costa Rica needs your help in managing their fisheries. In particular, they are considered levying a tax per metric ton of fish landings and want recommendations on what the level of the tax should be and your analysis of the consequences of that tax. Prepare your recommendations in a memo to the Fish Minister (max 1 page), with supporting appendices. Data . You have been provided with a dataset on annual fishing activity in the Gulf of Nicoya on the Pacific coast of Costa Rica. This was Costa Rica’s most important fishery during the 1970s and 1980s, accounting for two-thirds of the country’s fishing fleet and a third of its total marine landings. The data are drawn from a 1991 report by the World Resources Institute (Washington, DC) and the Tropical Science Center (San José, Costa Rica), Accounts Overdue: Natural Resource Depreciation in Costa Rica . The spreadsheet contains data for 19 years, 1970-88. Columns C-E contain data on landings (“catch”) of fish, sharks, and fish and sharks combined. The data are in metric tons. Column G contains data on the average price received by fishermen when they sell fish and sharks. These data are in colones/kg (not metric tons) and are in nominal (undeflated) terms. Columns I-Q contain data on the fishing fleet. Artisanal, not commercial, vessels comprised most of the fleet during the 1970s and 1980s. Artisanal fisherman used three main types of boats: botes and pangas, which are both small, simple craft that make day trips, and lanchas, which are larger and more powerful and stay out at sea for several days at a time. Columns I-K contain data on the number of vessels of each type. Botes are often oar-powered, while pangas and lanchas have motors. Columns M-O contain data on the average motor power per vessel, in kilowatts. Oar-powered botes were assumed to have 75 percent of the power of a bote with a 1-kw motor. Column Q contains data on total fishing cost for the entire fleet.
