     近幾年來,黃鰭鮪活魚運輸技術已建立,運送至箱網或陸上活存率高達95%以 上。臺灣處於颱風經過的區域,往往造成養殖魚大量死亡,黃鰭鮪養殖應以短期肥 育為主,本研究黃鰭鮪經四個月短期肥育,脂質高出野生16倍,明顯可見短期肥育 是較具有養殖契機。目前已蓄養15尾3年齡長腰鮪種魚,最大體型超過60公分,已接 近成熟繁殖體型,目前遷移至1500噸大型種魚池中蓄養,等待其自然繁殖產卵。養 殖池採用魚藻共生循環過濾系統,海木耳生長情況良好,有顯著降低池水氨氮及磷 酸鹽濃度。在保存精子種原方面,目前仍只有保存3尾黃鰭鮪,日後儘可能增加保存 數量。

研究報告摘要(英)


   In recent years, live yellowfin tuna transportation technology has been established, and the survival rate more than 95%. However, Taiwan location in the typhoons route, and often causing a culture fish large numbers of dead. The yellowfin tuna culture should be based on short-term fattening in the sea cage. In this study, the yellowfin tuna was shortterm fattening for 4 month, and yellowfin tuna lipid was more than 16 times of wild.We have raised 15 of 3-year-oldThunnus tonggolin a 1500 m 3recirculating broodstock pond combined with algal culture to clean sea water. The tuna body length is estimated over 60 cm and close to size at maturity. The cultured red algae,Sarcodia ceylanicagrew well and remove ammonia nitrogen and phosphate from circulating aquaculture system effectively. At present, we have preserved 3 yellowfin tuna semen and try to do more as far as possible.
