What effects, if any, have the new exclusive economic zones (EEZs), dramatic changes in exchange rates, higher fuel costs, and changes in the price of alternative protein sources had on trade and investment in Fisheries? Although world harvests of seafoods have increased since 1967, fish landings among Pacific-area countries, taken in total, have increased even more over the period. Fishing patterns have changed with respect to areas and species fished as well as vessel type. Preliminary results from two general econometric models suggest that relative prices while important, account for a small percentage of the varieties in export-market shares; that, on the demand side, such shares are relatively inelastic with respect to relative prices; that the income (food expenditure) elasticity of demand for shrim in Japan has been decreasing over time (price elasticities of demand are relatively low); and that the exchange rate may serve as a separate explanatory variable. Although certain insights can be gained if one looks at broad aggregates (countries and species), the more interesting questions should be addressed through a detailed investigation of the role that fisheries play in particular countries and of the market characteristics for particular species
