使用水試一號試驗船進行台灣東部海域的鮪類資源分布調查、鮪類仔稚魚豐度分布調查並蒐集鮪延繩釣投放各鉤深度的深溫記錄，解析鮪類的攝食深度及相關溫鹽資訊。(1)、探討臺灣近海主要生產鮪類的漁場、漁期、漁獲量和漁獲努力量等漁業資訊，以為進行資源評估的基礎。(2)、瞭解鮪類仔稚魚資源量在西太平洋的時空分布。(3)、所累積的漁獲資料可以和美國、日本所得結果相交換研討，並據以作為各主要鮪類資源評估的重要參考，以為未來爭取本海域生產配額之籌碼。

Tuna resource is abundant in central-western Pacific Ocean. Moreover, the easternwaters off Taiwan are noted as the migrating route and potential spawning grounds forPacific bluefin tuna. To determine the spatial and temporal distributions of tunas larva,especially for bluefin tuna, yellowfin tuna and bigeye tuna is an important and essentialstudy in tuna fisheries. After the following studies as: (1) collecting the fisheries statisticsdata, (2) measuring the fork length of tunas, (3) examining the geographical distributionof tunas larva and (4) analyzing the spawning biology of main tuna species, then withthe knowledge of the oceanography, i.e., drifting of current and characteristics of TS,the potential spawning grounds and fluctuations of the recruitment for tunas can beinferred.
