Review on Induced Breeding Research of Grey Mullet (Mugil cephalus) in Taiwan

Abstract

中文摘要1963年冬季在台灣高雄縣汕尾肇始烏魚人工繁殖試驗，第一年的試驗成果在日本魚類學雜誌(Japanese Journal of Ichthyology)發表，後來三年都沒有顯著之突破，因次停了一年。1968年冬季才正式重新在東港海洋研究所(Tungkang Marine Laboratory，正式名稱為台灣省水產試驗所東港分所，後來改稱行政院農業委員會水產試驗所東港生技研究中心)，加強以及改進烏魚稚魚之培育技術，克服了許多培育上的困難。1969年養活2尾，為世界上首次成功的紀錄，第2年育成431尾之後，第3、第4及第5年分別育成7786尾、23695尾及21688尾，並於1977年完成此魚之「完全養殖」。這一章詳述促進產卵、擠卵、受精、孵化、培育稚魚的詳實過程。AbstractThe first work on induced breeding of grey mullet in Taiwan was done by a team of dedicated workers and researchers during the early 1960s. Studies focused on general biology and habits, methods of collection and selection of mature spawners, transportation of spawners from the fishing grounds to the experimental station, techniques on maintenance of spawners in ponds, induced spawning and egg hatching, and preliminary experiments on larval rearing. From 1969 onwards, all works were undertaken at the newly established Tungkang Marine Laboratory including refinement and improvement of techniques that were developed, overcoming difficulties during the critical periods of rearing larvae, and improving the survival rate of the larvae. The first success in closing the reproductive cycle of grey mullet in captivity was achieved in 1977, and consequently the adoption of the mass propagation technology by the private sector. An important factor to consider in the mass propagation of grey mullet is a good source of spawners whether from the wild or from the aquaculture itself. Established protocols on induced spawning, stripping and artificial fertilization, egg incubation and hatching, and larval rearing are summarized in detail in this chapter.
