In order to meet the needs of marine fishery agencies

an operational GIS & RS application system for marine fishery in East China Sea has been developed. RS

GIS

CBR

Database/Data warehouse

and GPS technologies have been integrated in this system. Because there are fuzzy

dynamic

three dimension characters in the marine environment

traditional GIS can not meet the needs. For the spatial-temporal dynamic change character of fishing ground

and there is not robust math model for forecasting

Case-based reasoning technology has been applied. For the operational character

layer-map-atlas hierarchy based data organizing method has been put forward and applied

and template is also applied for layer making. Expert system and model base management technologies have been integrated for fish stock access. An extent spatial ER methods is presented for dynamic marine fishery data concept modeling. The vector primitives （face

edge

vertex and volume） are introduced into 3D raster structure in order to express and analyze three dimension marine fishery data. This system can nowcast and forecast fishing ground of East China Sea for every week

and access fish stock of East China Sea for every fishing season

and this system also can be served for marine fishery management

eg. fishing boat tracing.
