一.多重衛星影像於漁場形成機制探討及漁海況速預報之應用In this study, the semi-automatic detection and geostatistical technology will bedeveloped to apply for hydrographic features (i.e. cold & warm eddy, fronts) extractionin multi-satellite images, which include the pseudo-color sea surface temperature images,ocean color images and their contour maps. The value-added satellite images nowcastwill be announced to the fisherman to supply more helpful and serviceful fishing groundinformation, especially in the mullet fishery industry.Integrated the multi-satellite images and in-situ hydrographic data by geographicinformation system (GIS) will expect to help decrease the coast of waste oil and promotethe efficiency of fishing operation. In addition, the instable mullet-fishing production hadbeen caused by the global warming and the inappropriate fishing method from theChina's fisherman. This study will analyze the yearly migration and distribution, age andsize structure dynamics and fishery-oceanographic data of the mullet to understand thefish population spatial-temporal distribution and the mechanism of the fishing groundformation.二.應用3S技術整合台灣沿岸養殖環境資訊與監測模式之建立Cage culture in coastal waters become popular in southern Taiwan. Problems frequentlyarise because of poor site selection. In order to acquire hydrographic conditions ofcoastal fishing grounds and cage culture areas, a prototype of data collection andtransmission system will be established. Oceangraphic parameters such as watertemperature, light intensity, turbidity others of the culture environment are collected byvarious sensors setting on site of a cage . Also, a CCD camera is used to get images offish activities in the cage. All the digital data and images are recorded in the memory ofeach sensor for a period of time and transmitted by means of wireless technology likeGPRS or Wi-Fi technology to the server in computer center of Fisheries ResearchInstitute. Integration of 3S technology(GPS,GIS,RS) will be useful to aquaculture siteselection or disaster pre-warning analysis applications .The collected data is processedand transferred into a database for further analysis using GIS system.-
