本研之目的在於建立SPF白蝦種蝦庫及其繁養殖技術並推廣防疫技術，以提高白蝦養殖收成與我國白蝦養殖的競爭力。所得結果如下：1. 白蝦種原之蒐集引進：目前已自國內外業者蒐集引進白蝦種原7批並通過WSSV、TSV、YHV及GAV IHHNV等四種病毒之篩檢。2.各批白蝦種原在成長與活存的比較：所得結果如下：試驗一：二組之成長差異不大。活存率及產量以第6批高於第1與第3批之雜交子代。試驗二：四批之成長差異不大。活存率及產量以第1批最高、第2批次之、第4/5批最低。3. SPF白蝦養殖技術之建立：完成SPF白蝦在HDPE池中進行高密度養殖之成長試驗。所得結果如下：放養時蝦苗體重0.01g，收成時體重為25.2g，活存率為72.3%，單位面積產量為3.64 kg/m2，每週平均成長速度為1.08 g，飼料轉換比為1.86。4. SPF白蝦繁養殖相關技術之技轉與推廣：共育成SPF白蝦苗約1千萬尾，大部份提供技轉廠商、少部份提供輔導廠商生產大蝦之用，97年度技轉金共新台幣97萬6千5百元整。

研究報告摘要(英) The objectives of the project are to establish the SPF broodstock of Litopenaeus vannamei and the techniques of rearing and breeding and to promote the technology of bisecured facilities, to increases the yield and competitiveness of white shrimps culture in Taiwan. The results are following: Six stocks were obtained and the virus diseases were diagnosed using commercial kits for WSSV, TSV, IHHNV and YHV/GAV. None of the above five virus was ever been detected in the samples. The growth and survival were compared among the stocks, in experiment 1, survival and yield were higher in Stock 6 than the hybrid of stock 2and 3. In experiment 2, growth rate of four stocks were about the same. Survival was highest in stock 1, follows by stock 2, while stock4 and 5 were lowest. SPF white shrimp were cultured in a biosecured HDPE pond of 650 m2 for 162 days at culture density of 200 shrimp/m2. At harvest, shrimp grew from 0.01g to 25.2g with survival rate of 72.3%, yield of 3.64 kg/m2, growth rate of 1.08 g/week and FCR of 1.86, respectively.
