1   協助巴拉圭建立條紋鴨嘴鯰人工繁殖技術之研究
Study of assisting Paraguay to establish artificial breeding technology for barred sorubim (Pseudoplatystoma fasciatum)
    pages 1-12
劉恒信、周俊賢、白志年*
   

本研究之鴨嘴鯰種魚主要係捕獲自南美洲巴拉圭河,捕撈漁法以短時間流刺網對種魚的傷害最輕,活存率較高。另,由民間養殖場採購巴西雜交鯰進行繁殖試驗。本研究計採集75尾野生種魚,其中只有4尾於捕獲時確認卵巢卵粒偏核率超過30%,經1次催產注射即可採卵,且受精率平均高達72.5%。另,攜回中心培育之種魚中只有3尾之卵粒偏核率超過20%......更多

The breeder of barred sorubim (Pseudoplatystoma fasciatum) in this study mostly caught from the Paraguay River of South America. According to different fishing methods, “Drift Gillnet” caused the least damage to fish, and got a higher survival rate.

International shark management and conservation
    pages 27-34
劉光明
   

鯊魚是海洋中頂端的掠食者,在海洋生態系中扮演非常重要的角色,全球鯊魚漁獲量在2000年達到歷史新高,由於過度的開發造成鯊魚資源的銳減。因此,近年來鯊魚資源保育與管理之議題逐漸成為國際矚目之焦點。聯合國糧農組織(FAO)率先提出了國際鯊魚保育與管理國際行動計畫,其他國際保育組織如國際自然保育聯盟(IUCN)及瀕危野生動植物國際貿易公約(CITES)也分別提出......更多

Sharks are apex predators in the marine ecosystem and they play an important role in the system. The global shark catch peaked around 2000 and overexploitation resulted in the decline of shark stocks. Therefore, shark conservation and management have attracted great attention in recent years......MORE
