＜BR＞＜P＞我國位處於熱帶及亞熱帶交界區，臺灣四周自然海域無法進行高價冷水性海水物種之繁養殖，國內高價冷水性水產品市場均仰賴國外進口，並因為長途冷凍運輸，不符合環保減碳的時代趨勢。臺灣東部深層海水離岸距離短，具取水優勢，我國應透過深層海水養殖科技發展，發展深層海水養殖產業，自行繁養殖冷水性海水物種，直接供應本國市場，可提高我國養殖水產品的多樣性與產業價值。但由於海洋深層水屬寶貴資源，為了達到海水低溫及能源多段利用之目的，本研究規劃多段利用深層海水進行不同物種配套養殖，妥善利用其水資源，搭配未來具發展性或可提升有限面積養殖獲利之物種水資源及土地資源充分利用，達到提高收益的目的，同時亦可降低排放水汙染的疑慮，另一方面可提高附加價值，養殖不同營養層及物種建立複合式養殖系統技術。本計畫將持續進行開發我國深層海水養殖技術，針對油斑及條石鯛養殖項目進行益生菌提升飼料效益之試驗，探討餵飼益生菌飼料對魚苗之成長、飼料效益及存活率是否有影響。在雜交九孔試驗，將探討飼養密度與餵食藻種的差異，對雜交九孔生長及水質管理的影響。同時針對海木耳進行營養鹽吸收試驗及最適生長條件試驗。依據試驗之數據結果，建立完整深層海水複合式養殖的最適標準流程，並進行成本效益分析。另藉由利用液態天然氣(LNG)冷排水開發冷水性物種養殖技術，希望透過冷水性養殖技術的開發引領我國養殖產業朝物種多元化發展。除延續進行大西洋鮭魚，仿刺參，牙鮃，皺紋盤鮑等養殖技術開發建立人工飼料與疾病防治技術，以建立適合台灣之商業化養殖模式，擴大冷水性物種養殖計畫開發成果，建立量產化技術並進行藻類重金屬累積等食品安全分析。同時針對不同養殖物種建立養殖技術手冊，以期成為未來發展與輔導產業生產之重要基礎資料，同時分析冷水性養殖物種之成本效益並進行產業規模之規劃評估，以創造產業多元化與創新發展。＜/P＞＜P＞＜/P＞＜BR＞＜P＞Taiwan is located in between of the tropics and subtropics, and consequently Taiwanese mariculture industry cannot culture high economical coldwater fishes. Taiwan coldwater fishes market depends on foreign imports. Also, because of the long distance refrigerated transport for product, it wouldn’t conform for goal of carbon reduction. Eastern Taiwan coast has abundant resources of deep sea water in the near distance and therefore convenient to pumping deep sea water. Fisheries authority would be needed to develop the deep sea water applied technology most suitable and feasible for the aquaculture industry in Taiwan seafood market. However, due to the scarcity of deep sea water, the multiple purposes of its adoption are highly recommended. An appropriate culturing plan of its adoption, therefore, should include the use of deep sea water in different species. Accompanied with the potential culturing species and the right water land resources, the plan will generate higher revenue and lower the concern on the contaminated water emission. Moreover, the appropriate culturing plan can be designed to address the value-add issue as well. Current project applies deep sea water that farming four culturing species which include ＜I＞Epinephelus moara＜/I＞, rock porgy, abalone, and ＜I＞Sarcodia ceylanica＜/I＞＜I＞＜/I＞in Zhiben river of Eastern Taiwan coast through factors of multiple aquaculture operations and economic analysis. Our research would be continuing the previous project results for development of deep sea water applied technology. Moreover, the research focuses on ＜I＞Epinephelus moara＜/I＞ and ＜I＞rock porgy＜/I＞ using probiotics in feed for, feed conversion ratio and survival rate. Also, this project would research that different of culture density and feed algae whether influencing growth performance and water quality management for abalone farming. Related research would also be explored the growth performance and nutritive absorption most suitable and feasible for particular conditions for the ＜I＞Sarcodia ceylanica. ＜/I＞According to our research results, we would complete an efficient business model by constructing such an integrated ecological system in deep sea water, and finding the right density and mixtures, while evaluating its cost-benefit analysis.＜/P＞＜P＞Another project is aimed for using the module of LNG cool water (CPC Corporation) for multi-temperature gradients. The project will be suitable for improving farming technology and Research and development for aqua feed for sea cucumber, abalone, flounder, salmon, enteromorpha and eaulerpa those cold- water- high- value aquatic species. And we will finish a manual instruction to promote the competitiveness of aqua industry and become practical and reliable. In order to connect with the associated applicable technology can be rooted in Taiwan and meanwhile create more value. We will timely study and exchange with oversea successful cases to make innovative concept of farming technology in cold- water- high- value aquatic species and to become the mirror of future development for cold water aquaculture industry. In the mean time we analyze the module farming factory its cost, to build a more economic pattern, and to make up the capacity gap. Eventually to make a development for technology of new cold water species and carry to the whole industry for diversification use. ＜/P＞＜P＞＜/P＞
