台灣的底拖網漁業在產值與產量上都是近海漁業中重要的一項,但自1980年以
後產量呈逐年遞減,底棲魚類資源量呈枯竭現象。因此,為確切能改善拖網作業漁
況,實有必要對本漁業之近況進行整體通盤的調查與瞭解。
有鑑於此,本研究將針對台灣西南海域主要經濟性魚種之生物生態、產卵期、
仔稚魚及作業漁場分佈狀況進行調查分析,再以科學方法精確判定產卵場之地理位
置,同時加入聲探技術的應用,藉以比較拖網及科學魚探同步探測之結果,進而做
為今後漁業資源評估、保育、管理及漁業行政決策等之參考依據。

研究報告摘要(英)


Bottom trawl fisheries are one of the important inshore fisheries in
Taiwan, but its landing is decreasing and demersal fish resources are
exhausted from1980. So, to improve definitely the fishing condition for
trawl fishery, it is necessary to investigate comprehensively the recent
situation of trawl fishery.
This studies in view of investigate the biological ecology, spawning
period, distributions of larva and fishing ground of the main economic
fishes in the southwestern waters of Taiwan, and to determine accurately
the geographical position of spawning ground by the scientific method,
join application of sounding technology at the same time; use to compare
trawl net and scientific fish detection with the result of survey
synchronously. and then it will be a reference basis in future for the
fishery resources estimate, conservation, management and fisheries
administration decision-making.
