摘要


爲解決利用人力讀取、抄錄漁海況資料之缺點,並將資料作連續、同步與有系統的分析,本研究就各普遍使用之漁航儀器之傳輸訊號深入瞭解其傳送方式、速度及資料內容、格式,依照這些資料內容開發一套漁海況資料自動處理系統。經過可行性研究、模擬測試及現場實測等之結果,應用本系統於宜蘭大里海域附近,發現人工魚礁之位置與劉等(1990)所作之研究相去不遠,另分析其附近海潮流,發現該海域有局部湧昇的現象,而由流速流向分布圖,發現可能爲人工魚礁造成的擾流所形成。顯見本系統不但效率高,省時省力,可即時記錄及處理資料,使資料之準確性提高;對於海底地形、海域之表層水溫及海潮流變化等觀察亦發揮極大效用。

An oceanographic and fishery information processing system for fishery hasbeen developed.This system is to collect for oceanographic data automatically andimprove their accuracy and continuity.In this system all the data are directlytransfer from fishery-navigation equipment to data processing computer.Thesystem has been tested at the offshore nearby TA-LI,I-LAN Hsien,northeast ofTaiwan.The tubulence effect has been recognized in an artificial reef programdeveloped in this research for testing the information processing system.Thesystem can be used to develop isobath,analyze tide and current for loughprojects.The oceanographic information that are generated by the system can beused to determine candidate positions for artificial reefs and setnets.
