一.鬼頭刀資源量之調查與評估This project is aiming to efficiently develop dolphin fish resources in the Eastern Taiwanby understanding precisely the environment and habitation information in order topromote the fishing industry within the structure of international fishing responsibility.The critical items are: 1. Sampling and measuring the length of dolphin fish in Hsin-Kang fish market; 2. Collect catches of dolphin fish; 3. Standering cpue of dolphin fishaccording to classification of fishing boat and fishing gear. In the end of the project weexpect to establish a complete data bank for the dolphin fish resources in the Eastern Taiwan, understand precisely the historical trend and current situation of dolphinfishfishing, and establish the TAC with the systematically collected and analyzed data.二.高度洄游性魚類資源調查、評估研究-雲嘉地區沿岸海域斑節蝦資源保育之研究The purpose of this project is to establish the techniques of stock enhancement along thecoastal of Yulin and Chiayi of kuruma prawn. The objectives are to establish the massproduction of seed, large-scale nursery, tagging techniques and to evaluate the effort ofreleasing of kuruma prawn. This year had obtained 1000 thousand 3-5 ㎝juvenile and10 thousand 10-15 ㎝adult prawn for releasing. Those were in 100:1 ratio for tagging.And analysis Mitochondria's DNA to establish DNA data of the releasing prawnpopulation.三.鮪類資源調查與評估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; it is an important andessential study in tuna fisheries. After the following studies as: (1) collecting the fisheriesstatistics data, (2) measuring the fork length of tunas, (3) examining the geographicaldistribution of tunas larva and (4) analyzing the spawning biology of main tuna species,then with the knowledge of the oceanography, i.e., drifting of current and characteristicsof TS, the potential spawning grounds and fluctuations of the recruitment for tunas canbe inferred.
