異種鰻養殖產業發展現況及養殖生產與管理技術之研究

年度 2014
計劃名稱 異種鰻養殖產業發展現況及養殖生產與管理技術之研究
中文摘要 異種鰻為臺灣新興養殖漁業,而一項養殖產業發展,唯有經濟面及生產面雙管齊下,產業方可永續經營。因此,本計畫於經濟面,針對產業之投入與產出進行資料收集,應用經濟學及管理學原理進行分析,以期瞭解異種鰻養殖產業獲利關鍵及產業現階段與未來之發展策略;生產技術面,則針對養殖池底質與水質管理技術、飼料投餵管理技術、益生菌疾病預防防治管理技術、及異種鰻養殖標準作業流程等之建立,藉以推動科學化養殖管理之技術。 結果顯示,經營型態、池塘種類及養殖物種,均會影響產業之投入與獲利,不同地區的經濟性指標則差異不大。生產函數分析,黑鰻之生產彈性為2.42,鱸鰻則為1.07,產業均具有規模經濟效應。養殖生產管理技術方面,本計畫建立不同養殖環境下有益微生物與水質改良產品應用技術、應用腐植酸鈉對異種鰻養殖水質及作為飼料添加劑之管理技術、有益微生物在鱸鰻養殖上之應用技術,並評估17項風險危害因子,建立養殖標準作業流程。 未來臺灣異種鰻養殖產業,在短期策略方面:1.善用臺灣養殖經驗,克服目前異種鰻養殖技術層面問題,並透過臺灣加工技術,提升異種鰻產品優勢,擴大市場佔有率。2.落實水產品之各項檢驗制度,確保產品食用安全性,提昇產品信賴度,增加我國水產品出口競爭力。3.加強產銷合作組織功能,建立異種鰻資訊產銷平台,活絡產業資訊,提昇產品議價能力。4.透過4P及4C行銷策略,提升國內消費需求,建立基本市場需求量。長期發展策略則建議:1.創立臺灣異種鰻自有品牌,利用品牌形象拓展國際消費市場。2.積極參與異種鰻養殖國際交流,學習不同異種鰻養殖技術,提升我國異種鰻養殖生產管理能力,增加國際競爭力。3.開發多元鰻魚養殖種類,掌握生產技術,針對市場供需適時調節。4.透過產、官、學與鰻苗生產國洽談鰻苗進口供應相關協定,穩定國內鰻苗來源及需求。 據此,臺灣異種鰻養殖正處於產業生命週期的初始期,因此,尚有許多生產與經營管理等內部議題需要克服。未來,若異種鰻列入CITES,產業發展勢必再次遭遇外部衝擊,所以,異種鰻養殖產業,除藉由技術面之研發,掌握生產關鍵技術,也必須審慎考量產業發展之短、中、長期策略,以期我國鰻魚養殖產業之永續經營。
英文摘要 Non-Japanese Anguillid species aquaculture is emerging in Taiwan. The development of an aquaculture industry can only be sustainable if it is well-developed in economic and production dimensions. In the economic dimension, this study collected the data about industrial input and output, and applied the economics and management theories in analysis, in order to determine the key factors of making profits, and propose the present and future development strategies of the non-Japanese Anguillid species farming industry. In the production technology dimension, this study explored the farming pool sediment and water quality management technology, feed ration management technology, probiotic prevention of disease prevention and management technology and the establishment of standard operating procedures of the non-Japanese Anguillid species, in order to promote the scientific management of aquaculture technology. The results showed that operating patterns, types and breeding pond species affect the profitability and investment of the industry. The economic indicators in different regions vary slightly. According to the production function analysis, the production elasticity of Anguilla bicolor pacifica and Anguilla bicolor bicolor is 2.42, and it is 1.07 of the swamp eel. The industries have economies of scale. In the direction of aquaculture production and management technology, this study established the microorganisms and water quality improvement product application technology for different farming environments. In addition to applying the management technology of using sodium humate as the feed additive of non-Japanese Anguillid species water quality improvement, and probiotics in the farming of swamp eel, this study evaluated 17 risk factors to establish the standard operating procedures of farming. For the future development of non-Japanese Anguillid species aquaculture in Taiwan, short-term strategies are proposed as follows: (1) use Taiwan’s aquaculture experience to overcome the technological problems of non-Japanese Anguillid species aquaculture technology; the processing technology of Taiwan can increase the advantages of non-Japanese Anguillid species products to obtain more market shares; (2) implement the various inspection systems to ensure the food safety and enhance product reliability, improve the competitiveness of exports of Taiwan’s aquaculture products; (3) strengthen production-sales cooperation to establish non-Japanese Anguillid species information sales platform and improve product negotiation capabilities; (4) use 4P and 4C marketing strategies to improve consumption demands in Taiwan, and establish basic market demand. The suggestions for long term development strategy are as follows: (1) create self-owned brands of non-Japanese Anguillid species to expand the international consumption market by brand image; (2) actively participate in international exchange of non-Japanese Anguillid species, learn different aquaculture technologies, improve production management capabilities, and increase international competitiveness; (3) develop multiple eel aquaculture varieties, utilize production technology, and make adjustment according to market demand and supply; (4) negotiate eel fry import supply agreements with eel fry production countries through the industry, the government and the academia to stabilize the sources and demand of eel fry. Accordingly, Taiwan’s non-Japanese Anguillid species farming industry is in the initial stage of the life cycle. Therefore, there are various production and management and other internal issues to overcome. In the future, if non-Japanese Anguillid species is listed in CITES, industrial development is bound to encounter external shocks. Hence, for the non-Japanese Anguillid species farming industry, in addition to the technical dimension of research and develpoment and mastering of key production technology, the short, medium and long term strategies should be carefully considered for the sustainable development of Taiwan’s eel farming industry.
