    本計畫擬針對臺灣原生種淡水水生物進行繁殖飼育以建立種原保存進而探討合 理利用。在本年度中除持續建立鰟鮍魚類、粗首馬口鱲、羅漢魚及臺灣石賓之繁殖 方式,另外也確認粗首馬口鱲種魚可在誘導產卵注射後自行產卵以及建立羅漢魚受 精卵的蒐集方式,另本年度新蒐集齊氏田中魴鮍、七星鱧、菊池氏細鯽等原生種種 原進行培育並繁殖出魚苗。將持續研究確立種魚選育、魚卵孵化、魚苗飼育的方式 ,期能建立再現性高的魚苗生產模式。

研究報告摘要(英)


  More than 150 freshwater fish species have been identified in Taiwan. One fifth of them are endemic species or subspecies. Unfortunately ,the populations of many species have been declined because of human causes and environmental changes. Moreover, the exotic species have invased in the freshwater areas and have threaten the native population. This project is accordingly conducted to keep and breed those indigenous fish species as well as to develop the farming protocol. This year, we continue to establish the breeding methods of bitterling fish, Taiwan chub(Opsariichthys pachycephalus) , stone morocco(Pseudorasbora parva) and Taiwan torrent carp (Acrossocheilus paradoxus). In addition, it is also confirmed that mature Taiwan chub can be induced spawning repeatedly during the breeding period and the fish can spontaneous spawning without artificial stripped after injection .Recently also collected the native species such as, Paratanakia chii, Channa asiatica and Aphyoocypris kikuchii for cultivation and reproduction. This study will continue to explore the methods of fish brood breeding, fertilized eggs hatching and nursery feeding , to establish a repeatability model for fish fry breeding.
