(1)開發新的箱網養殖潛力物種，建立斑石鯛種魚培育、荷爾蒙催熟及人工繁殖技術，並完整紀錄斑石鯛受精卵胚胎發育紀錄及型態變化，供產業推廣使用，及建立孵化繁殖技術提升人工養殖魚苗產量，並研發斑石鯛人工飼料配方，探討其成長、活存及換肉率，以利於推動箱網養殖產業發展。(2)針對石鯛種原開發種群家系遺傳多型性或歧異度評估之應用分子標記、遺傳經濟性狀轉錄體資料庫之建立與差異基因表現分析、建立雜交鯛親本與子代種原遺傳管理資料庫、雜交鯛重要經濟性狀之確認與功能性分子標記篩選，以進行分子標記輔助基因鑑定與選育，作為經濟性狀遺傳改良與提升方向。另將益生菌應用於水產養殖，希望對水產養殖產業的發展有所助益。預計從魚類腸道分離益生菌，再進行鑑定及評估其安全性。(3)海鱺鏈球菌與發光桿菌乃海鱺重要之細菌性病原，目前國內仍僅限以抗生素治療本病，亦造成抗藥性菌株與藥物殘留等問題，因此本研究將發展雙價不活化注射型疫苗，以協助建立對抗此二疾病之關鍵技術，減少養殖海鱺之損失。(2)Studies on the emerging species in cage culture(1)This project aims to develop a new species for cage culture by establishing techniques in brood stock breeding, hormone based ripening method and artificial cultivation techniques on Oplegnathus punctatus. The growth and development of embryos will be fully recorded for industrial use, and artificial breeding techniques will be set up to increase the production of larva. Moreover, to further fulfill the requirement on cage culture development, research on developing artificial feed will be conducted by evaluating growth, survival rate and feed conversion rate of potential feed formula on O. punctatus.(2)Molecular markers for the determination of genetic polymorphism and heterogeneity of pedigrees, and transcript database of economic traits as well as gene expression analysis will be established in O. punctatus. Furthermore, a genetic database for the parent and progeny of crossbred Oplegnathus sp. will be built. Economic traits and functional markers for marker-assisted gene identification and selection will be established. In addition, probiotics that isolated and identified from fish will be scrutinized for the safety of its usage in aquaculture.(3)Diseases like streptococcal disease and photobacteriosis are two important bacterial problems in cobia culture, and so far the usage of antibiotics is the only way to treat these diseases. However, drug use has led to problems such as the emergence of drug resistant microbes and drug residues in farmed fish. Hence, this project aims to develop a divalent inactivated injection vaccine against these two pathogens and to reduce to loss of cobia culture industry.
