由野外採集之點石鯛種魚、中心保種之大法螺種貝已完成檢疫、馴化及投餵進食,目前大法螺種貝已成功進行人工繁殖工作,本年度幼生也提早順利孵化,刻正積極進行幼苗培育。點石鯛種魚也已經表現出正常進食、生長,預計將於104年春末利用現有之種魚進行首次的繁殖試驗。
箱網養殖區進來的嘉鱲魚及黃錫鯛種魚已經完成檢疫及馴餌,活存率97%(97/100),已經可以攝食沉性的海水魚飼料。嘉鱲魚目前仍在寄生蟲的檢疫程序中,活存率99%(99/100),以人工的軟性飼料投餵。
虎斑烏賊Sepia pharaonis,具高食物轉換率、成長快速及短的生命週期,擬建立量產及養殖相關技術,成為發展潛力之海水養殖新興物種。初期餌料試驗結果顯示,以投餵活的五鬚蝦幼蝦組>活的豐年蝦成蟲組>冷凍豐年蝦成蝦組=剛孵化豐年蝦幼生組,虎斑烏賊初期餌料以活的餌料較佳,其中以五鬚蝦幼蝦最佳。

研究報告摘要(英)


The wild-caught Oplegnathus punctatus and Charonia tritonis were successfully quarantined、 acclimated and fed in artificial environments. The C. tritonis was used for artificial reproduction this year and planktonic larvae were acquired earlier than previous ones. The O. punctatus also showed normal appetite and growth and would be used for the artificial application in coming Spring.
The cultured broodstock of Pagrus major and Sparus sarba collected from cage, the survival rate were high. The procedure of quarantine was completed and was weaned from fish meal, the survival rate of Sparus sarba were 97.00%(97/100)。And the survival rate of Pagrus major were 99.00%(99/100),still under quarantine procedures.
Pharaoh cuttlefish Sepia pharaonis, with foods a high conversion rate, rapid growth and short life cycle, In order to establish production and farming technologies become to seawater aquaculture development potential candidate. The initial feed trials to 4 group with newly hatched brine shrimp larvae, living adults brine shrimp, frozen brine shrimp, and shrimp Exopalaemon orientis juveniles after 10 days rearing. The results was that Pharaoh cuttlefish total-length, manlte length and body weighing statistical analysis to feeding live shrimp Exopalaemon orientis juveniles was the best > live brine shrimp adult group> frozen brine shrimp to shrimp group = newly hatched brine shrimp larvae group respectively.
