計畫目標：鰻魚是我國重要的養殖魚種之一，至目前並無法得到天然的種鰻，而且天然的鰻苗來源亦不穩定，因此鰻魚人工催熟及幼苗培育成為重要的研究課題。目前雌雄鰻魚的人工催熟產卵、受精仍有許多的問題，例如雄鰻精巢的成熟與精子的品質不佳、雌種鰻成熟度不易操控、成熟種鰻不容易產卵、無法順利培育鰻線幼生等諸多問題，為了解決上述問題，許多基礎的生殖內分泌生理資料應急迫建立。因此本研究之長期目標為建立促進日本鰻成熟產卵與授精及育苗，並瞭解日本鰻生殖內分泌之特性。架構：本年度著重於以不同激素調控養殖日本鰻促性腺激素受體反應及性腺發育成熟之影響，並進行人工催熟繁殖之工作。預期效益：經由本研究之推動，預期將可建立鰻魚人工繁殖技術，並瞭解鰻魚的基礎生殖內分泌之特性。 Japanese eel, Anguilla japonica is an important cultured species in Taiwan. Mature spawners could not be obtained from wild population. The natural resource of eel larvae is even decreasing in recent years. Therefore, artificial induced maturation and fertilization, and larval rearing become important for eel culture. Several problems are still deserved to be studied such as the control of maturation in male and female eel, the quality of sperm and mature oocyte, the control of natural spawning and fertilization rate, the rearing of eel larvae, and larval nutrition. Also, it would accelerate the progress of artificial spawning and larval rearing if more information about the reproductive endocrine system in Japanese eel is provided. Therefore, the long-term objectives are to develop the routine techniques on the artificial induced maturation, spawning and larval rearing. The hypothalamo-pituitary-gonadal axis is also investigated. The objectives this year are to induce maturation and spawning, and also study the reproductive hormones in cultured Japanese eels. The effects of various hormones on the regulation of gonadotropin receptors will be conducted. The induction of maturation and spawning is also included. The research data will provide valuable information on the reproductive endocrine system in eels and promote eel aquaculture.
