The analysis is based on both primary and secondary data. Annual reports covering the period 1975-1993 (the most recent data available) prepared by Indonesia's Directorate General of Fisheries will be used to trace changes in landing and employment. The quality of DGF data published since 1975 are sufficiently reliable for the analysis of trends. Other published secondary data will be used to examine changes affecting resource availability and shrimp export. Primary data in the form of field observations and interviews provide the context for interpreting these secondary data.
