一、計畫目標 本計畫擬針對種苗防疫檢疫、優質種苗量產技術改進、高效能飼料、育種平台、產業分析、市場策略及種苗資訊體系、加強石斑種魚培育多樣化…等進行研究發展，以助市場拓展增加國際競爭力。使台灣成為亞太地區重要水產種苗供應中心並以取得亞太地區種苗市場三分之一(產值百億台幣)為目標。 二、重要工作項目 (1). 開發水產種苗生產管理系統與維護(企劃資訊組)。 (2). 生產成長快速之單雄性雜交吳郭魚苗60萬尾。(淡水繁養殖研究中心) (3).點帶石斑及鞍帶石斑種魚培育、病毒感染篩檢生產優質受精卵並藉洗卵、疫苗免疫、投餵抗病毒益生菌及免疫增強劑等方式提高石斑之育苗活存率。(海水繁養殖研究中心、台灣大學、海洋大學) (4).經育種成熟種魚以自交繁殖並進行魚苗試驗，並嘗試研發大量培育魚苗之循環養殖系統。(東港生技中心) 三、預期效益 (1). 建立成長快速且單雄性之雜交吳郭魚種苗生產技術，並逐年推廣魚苗，總計達200萬尾，估計養成總產量達1,800公噸、總產值達1億元。 (2).新興石斑魚種(油斑)種魚蓄養，進行選種、育種及保種，建構石斑魚繁養殖作業流程平台及育苗餌料生物開發與量產研究，提高石斑吋苗育成率至10%以上。 (3). 進行不同來源種魚繁殖生產受精卵以循環過濾系統育苗提高育成率， 供應優良海鱺受精卵予養殖業者。 (4).水產種苗資訊系統資料的持續增加，不僅記錄了本所養殖服務內容及了解養殖場養殖狀況，亦可掌握產業發展。

研究報告摘要(英) The hybrids between Nile tilapia (Oreochromis niloticus) and blue tilapia (Oreochromis aureus) kept in Freshwater Aquaculture Research Center, F.R.I. were high male percentage, and their size was larger than the commerical strain. This strain of tilapia could be extend to fish farmers. This aims of this work are to cultivate the brood stocks of Nile tilapia (Oreochromis niloticus) and blue tilapia (Oreochromis aureus) persistently, and produce the fry of fast-growth strain for extending to fish farmers. In this project, we plan to develop a set of prophylaxis strategy to produce groupers with ability against NNV infection, including immunizing brood fish to block the vertical transmission of NNV, and we will feed grouper larvae with anti-NNV probiotic bacteria, and evaluate the protection efficiency by bath challenge test. In addition, for achieving the output value doubling ,we will propagation longtooth grouper(Epinephelus brunneus),a temperate specis. This species also suitable for aquaculture in the winter in Taiwan, so we will intend to breeding this species and prouce offspring to promote private industry Cobia, Rachycentron canadum is a relatively hardy species which exhibits high rate of growth during larval and juvenile periods. Currently, it is considered to be a good candidate for cage culture. Cage-cultured cobia juveniles are susceptible to Photobacterium damselae subsp. piscicida, resulting in low survival rates. Another problem is that cultured Cobia performed attributes of inbreeding after several generations, including precocious, retarded growth and low disease resistance recently. It is necessary for improving the quality of cobia larvae by selective breeding and producing in a large amount.
