橫紋鱠(chocolate hind Cephalopholis boenak)是一種以珊瑚礁為主要棲息地的小 型石斑魚類，最大體長僅約26公分，雖不是主要的漁獲對象，但在石斑魚資源日漸 貧乏的狀況下， 漸漸成為最大宗的野生石斑魚來源。豹鱠( c o r a l t r o u t Plectropomus leopardus)是一種重要經濟性珊瑚礁魚類，最大體長可達120公分 ，於2004年列入國際自然保護聯盟紅皮書（IUCN Red List ）Near Threatened等級 。在台灣，尤其在北部海域及澎湖仍屬普遍的石斑魚種，然而對於橫紋鱠與豹鱠的 了解及研究卻很有限。爰此，本研究擬針對橫紋鱠，篩選其特有之微衛星基因座 ，探討其遺傳變異，並就成長速率、生殖腺發育週期變化等進行研究試驗。另一方 面，利用粒線體控制區基因(D-loop)針對豹鱠族群進行遺傳變異分析，俾利進行漁 業資源評估與建立人工繁養殖技術之參考資料。

研究報告摘要(英) Cephalopholis boenak, commonly called Chocolate hind, is a small body size (Maximum size: 26 cm TL) species with wide geographical distribution; Coral trout Plectropomus leopardus is a high valuable species with increasing market demand, while it was listed as Near Threatened at 2004 IUCN Red List. Both species are still abundant at northern Taiwan and Peng Hu, however, the knowledge of biology and ecology is poorly researched and understood. Therefore, the aims of this project are to (1) sieve out the specific microsatellite of C. boenak as genetic marker applicable for the genetic variation, (2) investigate the biological characters, such as growth rate, gonad development of C. boenak , (3) investigate the genetic variation of P. leopardus by mtDNA control region D-loop gene. And finally supply the reliable data for assessment and management of coral reef fisheries resource and utilization of aquaculture.
