水產研究(1993年創刊)-溫度、鹽度和餌藻種類對雙葉紡錘水蚤增殖的影響
主題: 溫度、鹽度和餌藻種類對雙葉紡錘水蚤增殖的影響
摘要(中):
海產魚苗培育過程中,需要大量餌料生物,而橈足類的不飽和脂肪酸含量高,是合適的餌料生物之一。雙葉紡錘水蚤 (Acartia bilobata) 是一種相當具有養殖潛力的橈足類,其無節幼生 (nauplius)體型小,適合做為海水經濟魚種成長初期之餌料。本研究分別探討雙葉紡錘水蚤在四種溫度22℃、27℃、32℃ 和37℃,七種鹽度5、10、15、20、25、30和35 psu以及三種餌藻等鞭金藻 (Isochrysis galbana) 、擬球藻 (Nannochloropis oculata) 和周氏扁藻 (Tetraselmis chui) 的增殖。結果顯示,雙葉紡錘水蚤最適培養條件為溫度27℃、鹽度15 psu及等鞭金藻。

摘要abstract(英): Rearing fish larvae process is needed to supply enough live food. Copepods and their nauplii contain highly unsaturated fatty acids are the most important live food sources for fish larvae. Acartia bilobata is a kind of copepod that has been cultured potentiality as live food for marine fish larvae in aquaculture. However, the techniques for culturing A. bilobata need to be improved in terms of its productivity. The effects of salinities, temperatures and food algae on the growth and production of A. bilobata were investigated.
Four temperature treatments of 22℃, 27℃, 32℃ and 37℃, seven salinity treatments of 5, 10, 15, 20, 25, 30 and 35 psu, and three microalgae species, Isochrysis galbana, Nannochloropis oculata and Tetraselmis chui were conducted, separately to find the effects on production of A. bilobata. Results showed that the optimum production of A. bilobata was achieved with temperature at 27 ℃, salinity at 15 psu, and fed with microalgae I. galbana.
