Abstract

Analysis of spatio-temporal fluctuations of East China Sea fishery resources using GIS F. Su, C. Zhou, Q. Shao, Y. Du & S. Wang State Key Lab. of Resource & Environmental Information System, Institute of Geography, Chinese Academy of Sciences, China Abstract Catch data from the East China Sea from 1987 through 1997, and other environmental factors, were overlain using Geographic Information System (GIS) technology. Maps of the spatio-temporal density of the demersal and pelagic fishery resources were produced. After analyzing the density distribution, we analyzed relationships between spatio-temporal distributions and environmental factors. The Kuroshio Current plays a major role in determining the fishery density distribution, especially for the demersal fishery. The South Yellow Sea Water Mass and the expansion of the Chang) iang Diluted Water (ECDW) are two other main environmental factors. The demersal fishery resource is mainly distributed between the 200-m
