On Taiwan, the art, science and, most particularly, the industry of aquaculture have advanced over the last twenty-five years, as one participant has put it, "from the stone age into the space age". This study examines the expansion of Taiwan's aquacultural area and the changing nature and value of its output from 1957 to 1983 in the context of Taiwan's general economic technological development. Taiwan's aquaculture provides examples of both intensive and extensive growth but there has been a general reduction in the amount of labor per unit of output. Changes in yield are explained by two kinds of innovations: modifications in the ways a given species of fish is produced (process innovations) and introductions to aquaculture of new species (product innovations). Such innovations proliferated in the twenty years after 1963 and, in theory, should present the entrepreneur with new sets of land-use options and managerial decisions. At the same time, the government of Taiwan has encouraged aquacultural production, initially to provide low-cost protein and subsequently to utilize marginal lands, intensify land use, allow capitalization of rural production and support rural family incomes. Production patterns are described for the Island as a whole and for individual administrative districts (hsien and hsi). Production histories of six major groups of cultivated species (carps, milkfish, oysters, tilapia, eel and grass shrimp) are reviewed in their specific spatial contexts in order to elucidate the relationships between production functions, kinds of innovations and spatial patterns of their adoption. Aquacultural revenues and production costs are specified insofar as the data allow. The relationship between innovations and changes in spatial variability of yields, prices and per hectare returns is investigated. The variation among species in returns per hectare is identified as the major reason for the variability among districts in returns per hectare. Spatial data are taken primarily from public sources, but have been complemented with direct observations of Taiwan's aquacultural landscape. The data show that expansion has occurred in districts outside the earlier core area of the industry and that gross and probably net revenues have also grown faster in the peripheral districts. Government support of research, extension and investment appear to reinforce these patterns. Finally, some implications for the implementation of aquacultural development in selected other countries are drawn from this case study.Subjects--Topical Terms:
